Changes in metabolism tied to risk of subsequent dementia
in new findings that may provide a prevention target.
Investigators found one of the clusters includes small high-density lipoprotein (HDL) metabolites associated with vascular dementia, while another cluster involves ketone bodies and citrate that are primarily associated with Alzheimer’s disease.
Ketone bodies, or ketones, are three related compounds – acetone, acetoacetic acid, and beta-hydroxybutyric acid (BHB) – produced by the liver during fat metabolism. Citrate is a salt or ester of citric acid.
These metabolite clusters are not only linked to the future development of dementia but also correlate with early pathology in those under age 60 years, said study investigator Cornelia M. van Duijn, PhD, professor of epidemiology at Nuffield Department of Population Health, Oxford (England) University.
“These metabolites flag early and late pathology and may be relevant as targets for prevention of dementia,” she noted.
The findings were presented at the 2021 Alzheimer’s Association International Conference.
Weight loss before dementia explained?
For the study, investigators included 125,000 patients from the UK Biobank, which includes 51,031 who were over age 60 at baseline. Of these, 1,188 developed dementia during a follow-up of about 10 years; 553 were diagnosed with Alzheimer’s disease and 298 with vascular dementia.
Researchers used a platform that covers 249 metabolic measures, including small molecules, fatty acids, and lipoprotein lipids.
They estimated risk associated with these metabolites, adjusting for age, sex, body mass index, technical variables, ethnicity, smoking, alcohol, education, metabolic and neuropsychiatric medication, and APOE4 genotypes.
Of the 249 metabolites, 47 (19%) were associated with dementia risk in those over age 60, after adjustment.
The investigators examined effect estimates for associations of metabolites with both Alzheimer’s disease and vascular dementia over age 60 versus hippocampal volume under age 60. They found a “very strong, very significant” association for Alzheimer’s disease, and a “marginally significant” association for vascular dementia, said Dr. van Duijn.
This would be expected, as there is a much stronger correlation between hippocampal and Alzheimer’s disease versus vascular dementia, she added.
“We not only see that the metabolites predict dementia, but also early pathology. This makes these findings rather interesting for targeting prevention,” she said. An analysis of total brain volume showed “very strong, very similar, very significant associations” for both Alzheimer’s disease and vascular dementia,” added Dr. van Duijn.
The researchers found a major shift in various metabolites involved in energy metabolism in the 10-year period before the diagnosis of Alzheimer’s disease. These changes include low levels of branched-chain amino acids and omega-3 fatty acids and high levels of glucose, citrate, acetone, beta-hydroxybutyrate, and acetate. “This finding is in line with that in APOE models that show reduced energy metabolism over age in the brain,” said Dr. van Duijn.
She added that high levels of some of these metabolites are associated with low body weight before dementia onset, which may explain the weight loss seen in patients before developing the disease. “Our hypothesis is that the liver is burning the fat reserves of the patients in order to provide the brain with fuel,” she explained.
Diet a prevention target?
The results also showed ketone bodies increase with age, which may represent the aging brain’s “compensation mechanism” to deal with an energy shortage, said Dr. van Duijn. “Supplementation of ketone bodies, branched-chain amino and omega-3 fatty acids may help support brain function.”
The fact that ketone bodies were positively associated with the risk of dementia is “a very important finding,” she said.
Following this and other presentations, session cochair Rima Kaddurah-Daouk, PhD, professor in psychiatry and behavioral sciences, Institute for Brain Sciences, Duke University, Durham, N.C., noted the research is “an important part of trying to decipher some of the mysteries in Alzheimer’s disease.”
The research contributes to the understanding of how nutrition and diet could influence metabolism and then the brain and is “opening the horizon” for thinking about “strategies for therapeutic interventions,” she said.
The study received funding support from the National Institute on Aging. The investigators have reported no relevant financial relationships.

‘Staggering’ increase in global dementia cases predicted by 2050
, new global prevalence data show. “These extreme increases are due largely to demographic trends, including population growth and aging,” said study investigator Emma Nichols, MPH, a researcher at the Institute for Health Metrics and Evaluation at the University of Washington in Seattle.
“Our estimates of expected increases can and should inform policy and planning efforts that will be needed to address the needs of the growing number of individuals with dementia in the future,” Ms. Nichols said.
The latest global prevalence data were reported at the 2021 Alzheimer’s Association International Conference.
“The numbers are staggering: Nearly 153 million cases of dementia are predicted worldwide by the year 2050. To put that in context, that number is equal to approximately half of the U.S. population in 2020,” Heather M. Snyder, PhD, vice president of medical and scientific relations for the Alzheimer’s Association, said in a statement.
Prevalence by country
To more accurately forecast global dementia prevalence and produce country-level estimates, the investigators leveraged data from 1999 to 2019 from the Global Burden of Disease study, a comprehensive set of estimates of worldwide health trends.
These data suggest global dementia cases will increase from 57.4 million (50.4 to 65.1) in 2019 to 152.8 million (130.8 to 175.9) in 2050.
Regions that will experience the worst of the increase are eastern Sub-Saharan Africa, North Africa, and the Middle East.
The researchers also factored into the forecasts expected trends in obesity, diabetes, smoking, and educational attainment.
Increases in better education around the world are projected to decrease dementia prevalence by 6.2 million cases worldwide by 2050. However, anticipated trends in smoking, high body mass index, and diabetes will offset this gain, increasing global dementia cases by 6.8 million cases.
“A reversal of these expected trends in cardiovascular risks would be necessary to alter the anticipated trends,” Ms. Nichols said. “Interventions targeted at modifiable risk factors for dementia represent a viable strategy to help address the anticipated trends in dementia burden,” she added.
Need for effective prevention, treatment
Commenting on the research, Rebecca M. Edelmayer, PhD, senior director of scientific engagement at the Alzheimer’s Association, said the global increase in dementia cases is something the association has been following for many years. “We know that if we do not find effective treatments that are going to stop, slow, or prevent Alzheimer’s disease, this number will continue to grow and it will continue to impact people globally,” Dr. Edelmayer said.
She noted that although there are some positive trends, including the fact that increased education may drive down dementia risk, other factors, such as smoking, high body mass index, and high blood sugar level, are predicted to increase in prevalence.
“Some of these factors are actually counterbalancing each other, and in the end, if we don’t continue to develop culturally tailored interventions or even risk reduction strategies for individuals across the globe, we will continue to see those numbers rise overall,” Dr. Edelmayer said.

Money buys life, and a cigarette maker wants to ‘unsmoke the world’
With COVID, the fun never ends
Welcome to America’s favorite pandemic-themed game show! Let’s play Covidiot Proof! And now, here’s your host, the lovely and talented Anthony Grouchy!
Tony: Hello everyone! Our first category today is America or [blank], and the first clue is for you, Don. This country requires “individuals to use a health pass to patronize indoor establishments such as restaurants, bars, nightclubs and cinemas.”
Don: Freedom-loving Americans would never stand for that, Tony, so I’m going to say Greece.
Tony: That’s correct, Don. One hundred points for you. Okay Joe, here’s your clue: In this country, some people wear disguises to get a COVID vaccination so their friends and families won’t find out.
Joe: Sounds like communism to me, Tony. I’ll say Cuba.
Tony: Sorry Joe, that’s incorrect. Don?
Don: The friends and families sound like freedom-loving Americans, so it must be America.
Tony: It is America. Missouri, to be exact. And now, one last question for both of you to win the game. True or false? Did the pastor of a church in Tennessee say that mask-wearers would be kicked out of the building because “I am not playing these Democrat games up in this church”?
Joe: That’s fake news, Tony. It’s gotta be false.
Tony: Incorrect! It’s absolutely true. That means today’s winner is … Joe? Yes, I’m being told that Tennessee goes to Joe.
Don: That’s bulls#&@! I won this thing! I’ll see you in court!
More money, more life
Does it seem to you that the wealthy live forever, while the less financially comfortable live shorter lives? If you answered, yes, it turns out that you’re right.
Researchers analyzed the effect of net worth at midlife with mortality. To take out genetic differences among the sample of 5,400 adults aged 46 years, the investigators also studied a subset of 2,490 twin and sibling pairs.
“The within-family association provides strong evidence that an association between wealth accumulation and life expectancy exists, because comparing siblings within the same family to each other controls for all of the life experience and biology that they share,” said coauthor Eric Finegood of Northwestern University, Chicago.
But what if one sibling has a history of cancer, heart disease, or other health conditions? The cost of treatment and employment limitations could affect someone’s ability to stack their wealth, right? Absolutely. The researchers took that into account and looked at only healthy individuals and found the same results. More money, longer life.
We have the policies and programs in place for heart health, diabetes prevention, and smoking cessation, as they are seen as major threats to public health. So why not do the same for financial security? A low bank account may just be more harmful.
Holding the ‘health care and wellness’ gun
Cigarettes are not good for us. We know this.
It’s, therefore, not surprising to learn that a business has requested for a U.K. ban on the sale of cigarettes by 2030. However, when that someone turns out to be the CEO of Philip Morris International, tobacco company and maker of Marlboro cigarettes, things get a little confusing.
Banning cigarettes, according to Jacek Olczak, would reduce confusion among consumers, many of whom feel that the alternatives are worse for their health. His company can “see the world without cigarettes ... and actually, the sooner it happens, the better it is for everyone.” A truly noble sentiment from the CEO of a large tobacco company. Nothing nefarious going on here.
And if those aren’t egregious business euphemisms, we don’t know what is.
Of course, for all the completely believable and sincere rhetoric, the fact is that Marlboros are still on the shelves. Philip Morris is still making and advertising them. If their concern was genuine, why wouldn’t they just stop manufacturing them now?
So, we ask ourselves if this a selfless act of kindness or is it an unscrupulous corporate act to get a leg up on their competitors? We’ll leave it up to the readers to decide.
Okay, we lied, it’s the second one.
Autopsy of the living dead
Imagine the absolute terror you’d feel if you opened your eyes to bright, blinding white lights only to see a bone saw 3 inches from your forehead and getting closer by the second. Horrifying for you, certainly, but think about the poor pathologist behind the saw who probably thought a zombie apocalypse was coming. This was close to being a reality for a 29-year-old prisoner at the Asturias Central Penitentiary in Spain.
Gonzalo Montoya Jiménez was discovered in his cell unresponsive. Three physicians examined him and found he was showing signs of death, such as cyanosis and rigor mortis. Mr. Jiménez was processed like any other body and was sent, in a body bag, to a hospital mortuary, where he spent time in a freezer for body preservation. Just before he was due for his autopsy, he began showing signs of life.
It’s not completely clear why this happened to poor Mr. Jiménez, but it was reported that he wasn’t feeling well the day before and that he has epilepsy. Hospital officials suggested he may have been cataleptic, possibly because he had trouble adhering to his medication schedule.
Mr. Jiménez was moved to another hospital under armed guard after coming back to life and regained consciousness after a day or so. Talk about cheating death.

“The within-family association provides strong evidence that an association between wealth accumulation and life expectancy exists, because comparing siblings within the same family to each other controls for all of the life experience and biology that they share,” said coauthor Eric Finegood of Northwestern University, Chicago.
But what if one sibling has a history of cancer, heart disease, or other health conditions? The cost of treatment and employment limitations could affect someone’s ability to stack their wealth, right? Absolutely. The researchers took that into account and looked at only healthy individuals and found the same results. More money, longer life.
We have the policies and programs in place for heart health, diabetes prevention, and smoking cessation, as they are seen as major threats to public health. So why not do the same for financial security? A low bank account may just be more harmful.
Holding the ‘health care and wellness’ gun
Cigarettes are not good for us. We know this.
It’s, therefore, not surprising to learn that a business has requested for a U.K. ban on the sale of cigarettes by 2030. However, when that someone turns out to be the CEO of Philip Morris International, tobacco company and maker of Marlboro cigarettes, things get a little confusing.
Banning cigarettes, according to Jacek Olczak, would reduce confusion among consumers, many of whom feel that the alternatives are worse for their health. His company can “see the world without cigarettes ... and actually, the sooner it happens, the better it is for everyone.” A truly noble sentiment from the CEO of a large tobacco company. Nothing nefarious going on here.
And if those aren’t egregious business euphemisms, we don’t know what is.
Of course, for all the completely believable and sincere rhetoric, the fact is that Marlboros are still on the shelves. Philip Morris is still making and advertising them. If their concern was genuine, why wouldn’t they just stop manufacturing them now?
So, we ask ourselves if this a selfless act of kindness or is it an unscrupulous corporate act to get a leg up on their competitors? We’ll leave it up to the readers to decide.
Okay, we lied, it’s the second one.
Autopsy of the living dead
Imagine the absolute terror you’d feel if you opened your eyes to bright, blinding white lights only to see a bone saw 3 inches from your forehead and getting closer by the second. Horrifying for you, certainly, but think about the poor pathologist behind the saw who probably thought a zombie apocalypse was coming. This was close to being a reality for a 29-year-old prisoner at the Asturias Central Penitentiary in Spain.
Gonzalo Montoya Jiménez was discovered in his cell unresponsive. Three physicians examined him and found he was showing signs of death, such as cyanosis and rigor mortis. Mr. Jiménez was processed like any other body and was sent, in a body bag, to a hospital mortuary, where he spent time in a freezer for body preservation. Just before he was due for his autopsy, he began showing signs of life.
It’s not completely clear why this happened to poor Mr. Jiménez, but it was reported that he wasn’t feeling well the day before and that he has epilepsy. Hospital officials suggested he may have been cataleptic, possibly because he had trouble adhering to his medication schedule.
Mr. Jiménez was moved to another hospital under armed guard after coming back to life and regained consciousness after a day or so. Talk about cheating death.
Coffee and the brain: ‘Concerning’ new data
according to the results of a large study.
“With coffee intake, moderation is the key, and especially high levels of consumption may have adverse long-term effects on the brain,” said study investigator Elina Hypponen, PhD, professor of nutritional and genetic epidemiology and director of the Australian Center for Precision Health at the University of South Australia.
“These new data are concerning, and there is a need to conduct further carefully controlled studies to clarify the effects of coffee on the brain.”
The study was published online June 24 in Nutritional Neuroscience.
Potent stimulant
Coffee is a potent nervous system stimulant and is among the most popular nonalcoholic beverages. Some previous research suggests it benefits the brain, but the investigators noted that other research shows a negative or U-shaped relationship.
To investigate, the researchers examined data from the U.K. Biobank, a long-term prospective epidemiologic study of more than 500,000 participants aged 37-73 years who were recruited in 22 assessment centers in the United Kingdom between March 2006 and October 2010.
During the baseline assessment, information was gathered using touchscreen questionnaires, verbal interviews, and physical examinations that involved collection of blood, urine, and saliva samples. An imaging substudy was incorporated in 2014, the goal of which was to conduct brain, heart, and body MRI imaging for 100,000 participants.
The investigators conducted analyses on disease outcomes for 398,646 participants for whom information on habitual coffee consumption was available. Brain volume analyses were conducted in 17,702 participants for whom valid brain imaging data were available.
Participants reported coffee intake in cups per day. Researchers grouped coffee consumption into seven categories: nondrinkers, decaffeinated coffee drinkers, and caffeinated coffee drinkers who consumed less than 1 cup/d, 1-2 cups/d, 3-4 cups/d, 5-6 cups/d, and more than 6 cups/d.
The reference category was those who consumed 1-2 cups/d, rather than those who abstained from coffee, because persons who abstain are more likely to be at suboptimal health.
“Comparing the health of coffee drinkers to the health of those choosing to abstain from coffee will typically lead to an impression of a health benefit, even if there would not be one,” said Dr. Hypponen.
The researchers obtained total and regional brain volumes from the MRI imaging substudy starting 4-6 years after baseline assessment. They accessed information on incident dementia and stroke using primary care data, hospital admission electronic health records, national death registers, and self-reported medical conditions.
Covariates included socioeconomic, health, and other factors, such as smoking, alcohol and tea consumption, physical activity, stressful life events, and body mass index.
The investigators found that there was a linear inverse association between coffee consumption and total brain volume (fully adjusted beta per cup, –1.42; 95% confidence interval, –1.89 to –0.94), with consistent patterns for gray matter, white matter, and hippocampal volumes.
There was no evidence to support an association with white matter hyperintensity (WMH) volume (beta –0.01; 95% CI, –0.07 to 0.05).
Higher consumption, higher risk
The analysis also revealed a nonlinear association between coffee consumption and the odds of dementia (P nonlinearity = .0001), with slightly higher odds seen with non–coffee drinkers and decaffeinated-coffee drinkers and more notable increases for participants in the highest categories of coffee consumption compared with light coffee drinkers.
After adjustment for all covariates, the odds ratio of dementia among persons in the category of coffee intake was 1.53 (95% CI, 1.28-1.83). After full adjustments, the association with heavy coffee consumption and stroke was not significant, although “we can’t exclude a weak effect,” said Dr. Hypponen.
“For the highest coffee consumption group, the data support an association which may be anywhere from 0% to 37% higher odds of stroke after full adjustment,” she added.
People at risk for hypertension may develop “unpleasant sensations” and stop drinking coffee before a serious adverse event occurs, said Dr. Hypponen. In a previous study, she and her colleagues showed that those who have genetically higher blood pressure tend to drink less coffee than their counterparts without the condition.
“This type of effect might be expected to naturally limit the adverse effects of coffee on the risk of stroke,” said Dr. Hypponen.
The odds remained elevated for participants drinking more than 6 cups/d after the researchers accounted for sleep quality. There were no differences in risk between men and women or by age.
An examination of the consumption of tea, which often contains caffeine, did not show an association with brain volume or the odds of dementia or stroke.
“We don’t know whether the difference between associations seen for coffee and tea intake reflects the difference in related caffeine intake or some other explanation, such as dehydration or effects operating through blood cholesterol,” said Dr. Hypponen.
Although reverse causation is possible, there’s no reason to believe that it is relevant to the study results. Genetic evidence suggests a causal role of higher coffee intake on risk for Alzheimer’s disease. In addition, results of a clinical trial support the association between higher caffeine intake and smaller gray matter volume, said Dr. Hypponen.
The mechanisms linking coffee consumption to brain volumes and dementia are not well established. However, Dr. Hypponen noted that caffeine has been used to induce apoptosis in cancer studies using glial cells.
“Furthermore, adenosine receptors, which mediate many of the effects of caffeine in the brain, have been suggested to influence the release of growth factors, which in turn can have an influence on astrocyte proliferation and angiogenesis in the brain,” she said.
Some types of coffee contain cafestol, which increases blood cholesterol and can have adverse effects though related mechanisms, said Dr. Hypponen.
The mechanism may also involve dehydration, which may have a harmful effect on the brain. The study suggested a correlation between dehydration and high coffee intake. “Of course, if this is the case, it is good news, as then we can do something about it simply by drinking some water every time we have a cup of coffee,” she said.
Misleading conclusions
Coffee contains antioxidants, and although previous studies have suggested it might be beneficial, this hypothesis is “too simplistic,” said Dr. Hypponen. “While coffee is not going to be all ‘bad’ either, there are a lot of controversies and suggestions about beneficial effects of coffee which may not be true, or at least do not reflect the full story.”
If the drinking of coffee is at least partly determined by an individual’s health status, then that would often lead to misleading conclusions in observational studies, said Dr. Hypponen.
“When one uses as a comparison people who already have poor health and who do not drink coffee because of that, coffee intake will by default appear beneficial simply because there are more people with disease among those choosing abstinence,” she said.
Before now, there was “very little evidence about the association between coffee intake and brain morphology,” and the studies that were conducted were relatively small, said Dr. Hypponen.
One of these smaller studies included a group of women aged 13-30 years. It found that coffee consumption was not associated with total brain volumes, but the findings suggested a U-shaped association with hippocampal volume; higher values were seen both for nondrinkers and the groups with higher consumption.
A small study of elderly patients with diabetes showed no evidence of an association with white matter volume, but there was a possible age-dependent association with gray matter volume.
The largest of the earlier studies had results that were very similar to those of the current study, suggesting that increasing coffee intake is associated with smaller hippocampal volumes, said Dr. Hypponen.
One of the study’s limitations included the fact that full dietary information was available only for a subsample and that factors such as dehydration were measured at baseline rather than at the time of brain MRI.
Another possible study limitation was the use of self-reported data and the fact that lifestyle changes may have occurred between baseline and MRI or covariate measurement.
In addition, the study is subject to a healthy-volunteer bias, and its implications are restricted to White British persons. The association needs to be studied in other ethnic populations, the authors noted.
A reason to cut back?
Commenting on the findings, Walter Willett, MD, DrPH, professor of epidemiology and nutrition, Harvard T. H. Chan School of Public Health, Boston, said the study is large and quite well done.
“It does raise questions about an increase in risk of dementia with six or more cups of coffee per day,” said Dr. Willett. “At the same time, it provides reassurance about lack of adverse effects of coffee for those consuming three or four cups per day, and little increase in risk, if any, with five cups per day.”
It’s not entirely clear whether the increase in risk with six or more cups of coffee per day represents a “true effect” of coffee, inasmuch as the study did not seem to adjust fully for dietary factors, high consumption of alcohol, or past smoking, said Dr. Willett.
The findings don’t suggest that coffee lovers should give up their Java. “But six or more cups per day is a lot, and those who drink that much might consider cutting back a bit while research continues,” said Dr. Willett.
The study was supported by the National Health and Medical Research Council.

FROM NUTRITIONAL NEUROSCIENCE
Remote cognitive assessments get positive mark
That is the message behind numerous publications in recent years, and the COVID-19 pandemic has accelerated that trend.
“The publications have just skyrocketed since 2018, but I think there are still some additional tests that we need to validate using this medium of assessment. Also, I think we need to kind of put on our thinking caps as a field and think outside the box. What novel tests can we develop that will capitalize upon the telehealth environment – interactive tests that are monitoring [the individuals’] performance in real time and giving the examiner feedback, things like that,” said Munro Cullum, PhD, in an interview. Dr. Cullum spoke on the topic at the 2021 Alzheimer’s Association International Conference.
Still, challenges remain, especially factors in the home environment that can adversely affect testing. “Some of our tests are a question-answer, pencil-paper sort of tests that can be well suited to a telemedicine environment, [but] other tests don’t translate as well. So we still have a ways to go to kind of get our test to the next generation when being administered during this type of assessment. But a lot of the verbal tests work extremely well,” said Dr. Cullum, who is a professor of psychiatry at the University of Texas Southwestern Medical Center, Dallas.
Preliminary evidence of equivalence
Some years ago, Dr. Cullum was interested in getting a better understanding of what existing tests could best be performed remotely, and what populations could most benefit from remote assessments. Existing studies were generally supportive of remote testing, but varied significantly in their methodology and design. He went on to publish a study in 2014 showing equivalency of existing tests in the in-person and remote environment, and that helped pave the way for a wave of more recent studies that seem to confirm equivalence of in-person methods.
“If you look at the literature overall, there is a nice, growing body of evidence suggesting support for a host of neuropsychological test instruments. For the most part, almost all have shown good reliability across test conditions,” Dr. Cullum said during the talk.
He said that he is often asked if different test norms will be required for remote tests, but that doesn’t seem to be a concern. “It looks like the regular old neuropsych test norms should serve as well in this remote assessment environment. Although as within hospital testing of patients, conservative use of norms is always an order. They are interpretive guidelines,” he added.
One concern is potential threats to validity within the home environment. He posted an image of a woman at home, taking a remote cognitive test. The desk she sat at overlooked a wooded scene, and had a sewing machine on it. A small dog lay in her lap. “So assessing the home environment, ensuring that it is as close to a clinical standard setting as possible, is certainly advised,” said Dr. Cullum.
Although much progress has been made in studying existing tests in a telemedicine environment, many commonly used tests still haven’t been studied. The risk of intrusions and distractions, and even connectivity issues, can be limiting factors. Some tests may be ineligible for remote use due to copyright issues that might prevent required materials from being displayed online. For those reasons and others, not all individuals are suited for a remote test.
Finally, remote tests should be viewed with healthy skepticism. “In doing clinical evaluations this way, we have to be extra careful to not mis- or overinterpret the findings in case there were any distractions or glitches in the examination that came up during the test,” said Dr. Cullum.
Looking toward the future
Moving forward, Dr. Cullum called for more research to design new tests to exploit the telehealth format. “I think this is a really important opportunity for new test development in neuropsychology with increasing incorporation of computerized measures and integration with more cognitive neuroscience and clinical neuropsychology principles.”
He also suggested that remote testing could be combined with neuroimaging, neuromodulation, and even portable magnetoencephalography. “These opportunities for research can enhance compliance, enhance large-scale studies to allow for the inclusion of brief cognitive outcome metrics that might not have other otherwise been [possible],” said Dr. Cullum.
During the question-and-answer session, someone asked if the momentum towards telehealth will continue once the COVID-19 pandemic recedes. “We believe telehealth is here to stay, or at least I do,” said session moderator Allison Lindauer, PhD, who was asked to comment. Dr. Lindauer is an associate professor at the Layton Aging and Alzheimer’s Disease Center in Portland, Ore.
Dr. Lindauer has also conducted studies on telehealth-delivered assessments and also found encouraging results. “Work like this says, we have confidence in our work, we can believe that what we’re assessing and what we’re doing – if we did it face to face, we would get similar results,” Dr. Lindauer said in an interview.
Plenty of challenges remain, and the most important is widely available broadband internet, said Dr. Lindauer. “We need a huge push to get broadband everywhere. Granted, you’re going to have people that don’t want to use the computer, or they’re nervous about doing it online. But in my experience, most people with enough coaching can do it and are fine with it.”
Dr. Cullum and Dr. Lindauer have no relevant financial disclosures.
That is the message behind numerous publications in recent years, and the COVID-19 pandemic has accelerated that trend.
“The publications have just skyrocketed since 2018, but I think there are still some additional tests that we need to validate using this medium of assessment. Also, I think we need to kind of put on our thinking caps as a field and think outside the box. What novel tests can we develop that will capitalize upon the telehealth environment – interactive tests that are monitoring [the individuals’] performance in real time and giving the examiner feedback, things like that,” said Munro Cullum, PhD, in an interview. Dr. Cullum spoke on the topic at the 2021 Alzheimer’s Association International Conference.
Still, challenges remain, especially factors in the home environment that can adversely affect testing. “Some of our tests are a question-answer, pencil-paper sort of tests that can be well suited to a telemedicine environment, [but] other tests don’t translate as well. So we still have a ways to go to kind of get our test to the next generation when being administered during this type of assessment. But a lot of the verbal tests work extremely well,” said Dr. Cullum, who is a professor of psychiatry at the University of Texas Southwestern Medical Center, Dallas.
Preliminary evidence of equivalence
Some years ago, Dr. Cullum was interested in getting a better understanding of what existing tests could best be performed remotely, and what populations could most benefit from remote assessments. Existing studies were generally supportive of remote testing, but varied significantly in their methodology and design. He went on to publish a study in 2014 showing equivalency of existing tests in the in-person and remote environment, and that helped pave the way for a wave of more recent studies that seem to confirm equivalence of in-person methods.
“If you look at the literature overall, there is a nice, growing body of evidence suggesting support for a host of neuropsychological test instruments. For the most part, almost all have shown good reliability across test conditions,” Dr. Cullum said during the talk.
He said that he is often asked if different test norms will be required for remote tests, but that doesn’t seem to be a concern. “It looks like the regular old neuropsych test norms should serve as well in this remote assessment environment. Although as within hospital testing of patients, conservative use of norms is always an order. They are interpretive guidelines,” he added.
One concern is potential threats to validity within the home environment. He posted an image of a woman at home, taking a remote cognitive test. The desk she sat at overlooked a wooded scene, and had a sewing machine on it. A small dog lay in her lap. “So assessing the home environment, ensuring that it is as close to a clinical standard setting as possible, is certainly advised,” said Dr. Cullum.
Although much progress has been made in studying existing tests in a telemedicine environment, many commonly used tests still haven’t been studied. The risk of intrusions and distractions, and even connectivity issues, can be limiting factors. Some tests may be ineligible for remote use due to copyright issues that might prevent required materials from being displayed online. For those reasons and others, not all individuals are suited for a remote test.
Finally, remote tests should be viewed with healthy skepticism. “In doing clinical evaluations this way, we have to be extra careful to not mis- or overinterpret the findings in case there were any distractions or glitches in the examination that came up during the test,” said Dr. Cullum.

Reducing air pollution is linked to slowed brain aging and lower dementia risk
, new research reveals. The findings have implications for individual behaviors, such as avoiding areas with poor air quality, but they also have implications for public policy, said study investigator, Xinhui Wang, PhD, assistant professor of research neurology, department of neurology, University of Southern California, Los Angeles.
“Controlling air quality has great benefits not only for the short-term, for example for pulmonary function or very broadly mortality, but can impact brain function and slow memory function decline and in the long run may reduce dementia cases.”
The findings were presented at the 2021 Alzheimer’s Association International Conference.
New approach
Previous research examining the impact of reducing air pollution, which has primarily examined respiratory illnesses and mortality, showed it is beneficial. However, no previous studies have examined the impact of improved air quality on cognitive function.
The current study used a subset of participants from the Women’s Health Initiative Memory Study-Epidemiology of Cognitive Health Outcomes (WHIMS-ECHO), which evaluated whether postmenopausal women derive cognitive benefit from hormone therapy.
The analysis included 2,232 community-dwelling older women aged 74-92 (mean age, 81.5 years) who did not have dementia at study enrollment.
Researchers obtained measures of participants’ annual cognitive function from 2008 to 2018. These measures included general cognitive status assessed using the Telephone Interview for Cognitive Status-modified (TICSm) and episodic memory assessed by the telephone-based California Verbal Learning Test (CVLT).
The investigators used complex geographical covariates to estimate exposure to fine particulate matter (PM2.5) and nitrogen dioxide (NO2), in areas where individual participants lived from 1996 to 2012. The investigators averaged measures over 3-year periods immediately preceding (recent exposure) and 10 years prior to (remote exposure) enrollment, then calculated individual-level improvements in air quality as the reduction from remote to recent exposures.
The researchers examined pollution exposure and cognitive outcomes at different times to determine causation.
“Maybe the relationship isn’t causal and is just an association, so we tried to separate the timeframe for exposure and outcome and make sure the exposure was before we measured the outcome,” said Dr. Wang.
The investigators adjusted for multiple sociodemographic, lifestyle, and clinical characteristics.
Reduced dementia risk
The analysis showed air quality improved significantly for both PM2.5 and NO2 before study enrollment. “For almost 95% of the subjects in our study, air quality improved over the 10 years,” said Dr. Wang.
During a median follow-up of 6.2 years, there was a significant decline in cognitive status and episodic memory in study participants, which makes sense, said Dr. Wang, because cognitive function naturally declines with age.
However, a 10% improvement in air quality PM2.5 and NO2 resulted in a respective 14% and 26% decreased risk for dementia. This translates into a level of risk seen in women 2 to 3 years younger.
Greater air quality improvement was associated with slower decline in both general cognitive status and episodic memory.
“Participants all declined in cognitive function, but living in areas with the greatest air quality improvement slowed this decline,” said Dr. Wang.
“Whether you look at global cognitive function or memory-specific function, and whether you look at PM2.5 or NO2, slower decline was in the range of someone who is 1-2 years younger.”
The associations did not significantly differ by age, region, education, APOE ε4 genotypes, or cardiovascular risk factors.
Patients concerned about cognitive decline can take steps to avoid exposure to pollution by wearing a mask; avoiding heavy traffic, fires, and smoke; or moving to an area with better air quality, said Dr. Wang.
“But our study mainly tried to provide some evidence for policymakers and regulators,” she added.
Another study carried out by the same investigators suggests pollution may affect various cognitive functions differently. This analysis used the same cohort, timeframe, and air quality improvement indicators as the first study but examined the association with specific cognitive domains, including episodic memory, working memory, attention/executive function, and language.
The investigators found women living in locations with greater PM2.5 improvement performed better on tests of episodic memory (P = .002), working memory (P = .01) and attention/executive function (P = .01), but not language. Findings were similar for improved NO2.
When looking at air quality improvement and trajectory slopes of decline across cognitive functions, only the association between improved NO2 and slower episodic memory decline was statistically significant (P < 0.001). “The other domains were marginal or not significant,” said Dr. Wang.
“This suggests that brain regions are impacted differently,” she said, adding that various brain areas oversee different cognitive functions.
Important policy implications
Commenting on the research, Rebecca Edelmayer, PhD, senior director of scientific engagement, Alzheimer’s Association, said she welcomes new research on environmental factors that affect Alzheimer’s disease.
Whereas previous studies have linked longterm air pollution exposure to accumulation of Alzheimer’s disease-related brain plaques and increased risk of dementia, “these newer studies provide some of the first evidence to suggest that actually reducing pollution is associated with lower risk of all-cause dementia,” said Dr. Edelmayer.
Individuals can control some factors that contribute to dementia risk, such as exercise, diet, and physical activity, but it’s more difficult for them to control exposure to smog and pollution, she said.
“This is probably going to require changes to policy from federal and local governments and businesses, to start addressing the need to improve air quality to help reduce risk for dementia.”

First guidance on appropriate use of controversial Alzheimer’s drug
, the controversial anti-amyloid drug that was approved by the U.S. Food and Drug Administration in June for adults with early Alzheimer’s disease.
“There are incredible gaps between the FDA label and what most of us in the field feel needs to happen in terms of detailed guidance on using this drug,” said panel member Alireza Atri, MD, PhD, director of the Banner Sun Health Research Institute (Banner Health) in Sun City, Arizona.
“This is a first-in-class drug where the vast majority of clinicians have no experience with it, and patients and their caregivers are already asking for it, and there are some really important conversations to be had – not only about who may qualify to begin with and also about potential effectiveness and safety,” Dr. Atri added.
The aducanumab recommendations were published online July 27 in the Journal of Prevention of Alzheimer’s Disease to coincide with their presentation at the 2021 Alzheimer’s Association International Conference.
A separate article outlining the key recommendations was published in Alzheimer’s and Dementia: Translational Research and Clinical Interventions.
Patient-centered focus
The panel recommends that aducanumab only be used for patients with clinical features similar to those of the patients who took part in the clinical trials that led to the drug’s approval – patients with mild cognitive impairment (MCI) due to Alzheimer’s disease and mild Alzheimer’s disease dementia who have brain amyloid, as confirmed on amyloid positron-emission tomography (PET) or with cerebrospinal fluid (CSF) findings consistent with Alzheimer’s disease.
“You’re giving a drug that’s been approved on accelerated status for lowering amyloid, so amyloid status needs to be verified either by an amyloid PET scan or spinal fluid,” said Dr. Atri.
The panel also recommends that patients under consideration for aducanumab treatment have no psychiatric problems; that they be medically stable with no cardiovascular or cardiopulmonary conditions; that they are not taking anticoagulants; that they have no organ failure; and that they have no active cancer except for low-grade basal and squamous cell carcinomas. Current treatment with cholinesterase inhibitors and memantine is acceptable.
Dr. Atri noted that the prescribing label for the drug provides “broad strokes about titration.” The panel recommends that the drug be titrated to the highest dose to maximize opportunity for efficacy.
Monthly infusions should begin with a dose of 1 mg/kg for the first and second infusions. They should be increased to 3 mg/kg for infusions three and four and to 6 mg/kg for the fifth and sixth infusions. The intended dose of 10 mg/kg should be administered on the seventh infusion. The target dose level of 10 mg/kg should then be continued for the foreseeable future, the panel notes.
Safety monitoring is critically important. The panel recommends structured monitoring for amyloid-related imaging abnormalities of the effusion (ARIA-E) or hemorrhagic (ARIA-H) type. Patients should undergo MRI at least 1 year before aducanumab treatment is initiated or at baseline if there are any suggestions of a focal brain event since the last MRI. MRI should again be conducted before the fifth, seventh, and 12th infusions.
The panel says the “best practice” for providing aducanumab therapy is to adopt a patient-centered focus.
‘Not a cure’
“There should be comprehensive discussions and clear communication with the patient and care partner regarding the requirements for therapy, the expected outcome of therapy, potential risks and side effects, and the required safety monitoring, as well as uncertainties regarding individual responses and benefits,” said Dr. Atri.
“Patients need to know that this is not a cure. It’s not going to actually make their cognition better, but by removing amyloid, there is a reasonable chance it’s going to slow down clinical decline,” he added.
“You could have two identical twins who would qualify, and when you have this discussion with them, based on the risk and reward calculus, one may reasonably decide, ‘this is not for me,’ and that’s really important,” Dr. Atri added.
He cautioned that these initial recommendations are “a starting point, not a finishing point,” and will be updated as needed.
“This paper takes no stance on advocating for this treatment. But now that it’s available, let’s put up some guardrails and use it appropriately and safety,” Dr. Atri said.
“Clinicians are requesting clarity and more specific information about the appropriate use of this new treatment,” Rebecca Edelmayer, PhD, senior director of scientific engagement, the Alzheimer’s Association, said in an interview.
These first appropriate-use recommendations are “a first step and will certainly evolve over time as the medication is prescribed,” Dr. Edelmayer said.
The research had no specific funding. Dr. Atri has received honoraria for consulting; participating in independent data safety monitoring boards; providing educational lectures, programs, and materials; or serving on advisory boards for AbbVie, Acadia, Allergan, the Alzheimer’s Association, Axovant, AZ Therapies, Biogen, Grifols, Harvard Medical School Graduate Continuing Education, JOMDD, Lundbeck, Merck, Roche/Genentech, Novo Nordisk, Sunovion, and Suven. Dr. Edelmayer has disclosed no relevant financial relationships.

Dr. Atri noted that the prescribing label for the drug provides “broad strokes about titration.” The panel recommends that the drug be titrated to the highest dose to maximize opportunity for efficacy.
Monthly infusions should begin with a dose of 1 mg/kg for the first and second infusions. They should be increased to 3 mg/kg for infusions three and four and to 6 mg/kg for the fifth and sixth infusions. The intended dose of 10 mg/kg should be administered on the seventh infusion. The target dose level of 10 mg/kg should then be continued for the foreseeable future, the panel notes.
Safety monitoring is critically important. The panel recommends structured monitoring for amyloid-related imaging abnormalities of the effusion (ARIA-E) or hemorrhagic (ARIA-H) type. Patients should undergo MRI at least 1 year before aducanumab treatment is initiated or at baseline if there are any suggestions of a focal brain event since the last MRI. MRI should again be conducted before the fifth, seventh, and 12th infusions.
The panel says the “best practice” for providing aducanumab therapy is to adopt a patient-centered focus.
‘Not a cure’
“There should be comprehensive discussions and clear communication with the patient and care partner regarding the requirements for therapy, the expected outcome of therapy, potential risks and side effects, and the required safety monitoring, as well as uncertainties regarding individual responses and benefits,” said Dr. Atri.
“Patients need to know that this is not a cure. It’s not going to actually make their cognition better, but by removing amyloid, there is a reasonable chance it’s going to slow down clinical decline,” he added.
“You could have two identical twins who would qualify, and when you have this discussion with them, based on the risk and reward calculus, one may reasonably decide, ‘this is not for me,’ and that’s really important,” Dr. Atri added.
He cautioned that these initial recommendations are “a starting point, not a finishing point,” and will be updated as needed.
“This paper takes no stance on advocating for this treatment. But now that it’s available, let’s put up some guardrails and use it appropriately and safety,” Dr. Atri said.
“Clinicians are requesting clarity and more specific information about the appropriate use of this new treatment,” Rebecca Edelmayer, PhD, senior director of scientific engagement, the Alzheimer’s Association, said in an interview.
These first appropriate-use recommendations are “a first step and will certainly evolve over time as the medication is prescribed,” Dr. Edelmayer said.
The research had no specific funding. Dr. Atri has received honoraria for consulting; participating in independent data safety monitoring boards; providing educational lectures, programs, and materials; or serving on advisory boards for AbbVie, Acadia, Allergan, the Alzheimer’s Association, Axovant, AZ Therapies, Biogen, Grifols, Harvard Medical School Graduate Continuing Education, JOMDD, Lundbeck, Merck, Roche/Genentech, Novo Nordisk, Sunovion, and Suven.

, the controversial anti-amyloid drug that was approved by the U.S. Food and Drug Administration in June for adults with early Alzheimer’s disease.
“There are incredible gaps between the FDA label and what most of us in the field feel needs to happen in terms of detailed guidance on using this drug,” said panel member Alireza Atri, MD, PhD, director of the Banner Sun Health Research Institute (Banner Health) in Sun City, Arizona.
“This is a first-in-class drug where the vast majority of clinicians have no experience with it, and patients and their caregivers are already asking for it, and there are some really important conversations to be had – not only about who may qualify to begin with and also about potential effectiveness and safety,” Dr. Atri added.
The aducanumab recommendations were published online July 27 in the Journal of Prevention of Alzheimer’s Disease to coincide with their presentation at the 2021 Alzheimer’s Association International Conference.
A separate article outlining the key recommendations was published in Alzheimer’s and Dementia: Translational Research and Clinical Interventions.
Patient-centered focus
The panel recommends that aducanumab only be used for patients with clinical features similar to those of the patients who took part in the clinical trials that led to the drug’s approval – patients with mild cognitive impairment (MCI) due to Alzheimer’s disease and mild Alzheimer’s disease dementia who have brain amyloid, as confirmed on amyloid positron-emission tomography (PET) or with cerebrospinal fluid (CSF) findings consistent with Alzheimer’s disease.
“You’re giving a drug that’s been approved on accelerated status for lowering amyloid, so amyloid status needs to be verified either by an amyloid PET scan or spinal fluid,” said Dr. Atri.
The panel also recommends that patients under consideration for aducanumab treatment have no psychiatric problems; that they be medically stable with no cardiovascular or cardiopulmonary conditions; that they are not taking anticoagulants; that they have no organ failure; and that they have no active cancer except for low-grade basal and squamous cell carcinomas. Current treatment with cholinesterase inhibitors and memantine is acceptable.

When is MRI useful in the management of congenital melanocytic nevi?
When used for appropriate patients, results from a small multi-institutional study showed.
“The majority of congenital nevi are considered low risk for cutaneous and/or systemic complications,” Holly Neale said at the annual meeting of the Society for Pediatric Dermatology. “However, a subset of children born with higher-risk congenital nevi require close monitoring, as some features of congenital nevi have been associated with cutaneous melanoma, central nervous system melanoma, melanin in the brain or spine, and structural irregularities in the brain or spine. It’s important to understand which congenital nevi are considered higher risk in order to guide management and counseling decisions.”
One major management decision is to do a screening magnetic resonance image of the CNS to evaluate for neurologic involvement, said Ms. Neale, a fourth-year medical student at the University of Massachusetts, Worcester. Prior studies have shown that congenital nevi that are bigger than 20 cm, posterior axial location, and having more than one congenital nevus may predict CNS abnormalities, while recent guidelines from experts in the field suggest that any child with more than one congenital nevus at birth undergo screening MRI.
“However, guidelines are evolving, and more data is required to better understand the CNS abnormalities and patient outcomes for children with congenital nevi,” said Ms. Neale, who spent the past year as a pediatric dermatology research fellow at Massachusetts General Hospital, Boston.
To address this knowledge gap, she and colleagues at the University of Massachusetts, Massachusetts General Hospital, and Boston Children’s Hospital performed a retrospective chart review between Jan. 1, 2009, and Dec. 31, 2019, of individuals ages 18 and younger who had an MRI of the brain or spine with at least one dermatologist-diagnosed nevus as identified via key words in the medical record. Of the 909 patients screened, 46 met inclusion criteria, evenly split between males and females.
The most common location of the largest nevus was the trunk (in 41% of patients), followed by lesions that spanned multiple regions. More than one-third of patients had giant nevi (greater than 40 cm).
“The majority of images were considered nonconcerning, which includes normal, benign, or other findings such as trauma related, infectious, or orthopedic, which we did not classify as abnormal as it did not guide our study question,” Ms. Neale said. Specifically, 8% of spine images and 27% of brain images were considered “concerning,” defined as any finding that prompted further workup or monitoring, which includes findings concerning for melanin.
The most common brain finding was melanin (in eight children), and one child with brain melanin also had findings suggestive of melanin in the thoracic spine. The most common finding in spine MRIs was fatty filum (in four children), requiring intervention for tethering in only one individual. No cases of cutaneous melanoma developed during the study period, and only one patient with abnormal imaging had CNS melanoma, which was fatal.
All patients with findings suggestive of CNS melanin had more than four nevi present at birth, which is in line with current imaging screening guidelines. In addition, children with concerning imaging had higher rates of death, neurodevelopmental problems, seizures, and neurosurgery, compared with their counterparts with unremarkable imaging findings. Describing preliminary analyses, Ms. Neale said that a chi square analysis was performed to test statistical significance of these differences, “and neurosurgery was the only variable that children with concerning imaging were significantly more likely to experience, although sample size limits detection for the other variables.”
The authors concluded that MRI is a helpful tool when used in the appropriate clinical context for the management of congenital nevi. “As more children undergo imaging, we may discover more nonmelanin abnormalities,” she said.
Joseph M. Lam, MD, who was asked to comment on the study, said that the increased risk of CNS melanin in patients with larger lesions and in those with multiple lesions confirms previous reports.
“It is interesting to note that some patients with nonconcerning imaging results still had neurodevelopmental problems and seizures, albeit at a lower rate than those with concerning imaging results,” said Dr. Lam, a pediatric dermatologist at British Columbia Children’s Hospital, Vancouver. “The lack of a control group for comparison of rates of neurological sequelae, such as NDP, seizures and nonmelanin structural anomalies, limits the generalizability of the findings. However, this is a nice study that helps us understand better the CNS anomalies in CMN.”
Ms. Neale acknowledged certain limitations of the study, including the lack of a control group without CMN, the small number of patients, the potential for referral bias, and its retrospective design. Also, the proximity of the study period does not allow for chronic follow-up and detection of the development of melanoma or other problems in the future.
Ms. Neale and associates reported having no relevant financial disclosures. Dr. Lam disclosed that he has received speaker fees from Pierre Fabre.

Occipital nerve stimulation offers relief for patients with intractable chronic cluster headache
Occipital nerve stimulation may help safely prevent attacks of medically intractable chronic cluster headache, according to a new study.
Medically intractable chronic cluster headaches are unilateral headaches that cause excruciating pain during attacks, which may happen as frequently as eight times per day. They are refractory to, or intolerant of, preventive medications typically used in chronic cluster headaches.
“ONS was associated with a major, rapid, and sustained improvement of severe and long-lasting medically intractable chronic cluster headache, both at high and low intensity,” Leopoldine A. Wilbrink, MD, of Leiden (the Netherlands) University Medical Centre, and coauthors wrote in their paper.
The findings were published online.
The multicenter, randomized, double-blind, phase 3 clinical trial was carried out at seven hospitals in the Netherlands, Belgium, Germany, and Hungary. A total of 150 patients with suspected medically intractable chronic cluster headache were enrolled between October 2010 and December 2017, and observed for 12 weeks at baseline. Of those initially enrolled, 131 patients with at least four medically intractable chronic cluster headache attacks per week and a history of nonresponsiveness to at least three standard preventive medications were randomly allocated to one of two groups: Sixty-five patients received 24 weeks of ONS at high intensity (100% intensity, or the intensity 10% below the threshold of discomfort as reported by the patient) while 66 received low-intensity (30%) ONS. At 25-48 weeks, the patients received open-label ONS.
Safe and well tolerated
“Because ONS causes paraesthesia, preventing masked comparison versus placebo, we compared high-intensity versus low-intensity ONS, which are hypothesised to cause similar paraesthesia, but with different efficacy,” wrote Dr. Wilbrink and colleagues.
From baseline to weeks 21-24, the median weekly mean attack frequencies decreased to 7.38 (95% confidence interval [CI]: 2.5-18.5, P < .0001). A median decrease in 5.21 attacks per week (–11.18 to –0.19, P < .0001) was observed.
The 100% ONS group saw a decrease in mean attack frequency from 17.58 at baseline (range, 9.83-29.33) to 9.5 (3-21.25) at 21-24 weeks with a median change of –4.08 (–11.92 to –0.25). In the 30% ONS group, the mean attack frequency decreased from 15 (9.25 to 22.33) to 6.75 (1.5-16.5) with a median change of –6.5 (–10.83 to –0.08).
At weeks 21-24, the difference in median weekly mean attack frequency between the groups was –2.42 (–5.17 to 3.33).
The authors stated that, in both groups, ONS was “safe and well tolerated.” A total of 129 adverse events were reported in the 100% ONS group and 95 in the 30% ONS group, of which 17 and 9 were considered serious, respectively. The serious adverse events required a short hospital stay to resolve minor hardware issues. The adverse events most frequently observed were local pain, impaired wound healing, neck stiffness, and hardware damage.
Low intensity stimulation may be best
“The main limitation of the study comes from the difficulty in defining the electrical dose, which was not constant across patients within each group, but individually adjusted depending on the perception of the ONS-induced paraesthesia,” Denys Fontaine, MD, and Michel Lanteri-Minet, MD, both from Université Cote D’Azur in France, wrote in an accompanying editorial.
Given that the primary outcome did not differ significantly between the treatment groups, the editorialists stated that “the lowest stimulation intensity that induces paraesthesia is sufficient to obtain an effect in the patients who respond. Increasing the electrical dose or intensity does not seem to bring better efficacy and might even induce discomfort (painful paraesthesia or shock-like sensations) that might substantially reduce the tolerance of this approach.”
While the trial did not provide convincing evidence of high intensity ONS in medically intractable chronic cluster headache, the editorialists are otherwise optimistic about the findings: “… considering the significant difference between baseline and the end of the randomised stimulation phase in both groups (about half of the patients showed a 50% decrease in attack frequency), the findings of this study support the favourable results of previous real-world studies, and indicate that a substantial proportion of patients with intractable chronic cluster headache, although not all, could have their condition substantially improved by ONS.” Dr. Fontaine and Dr. Lanteri-Minet added that they hope that “these data will help health authorities to recognise the efficacy of ONS and consider its approval for use in patients with intractable chronic cluster headache.”
Priorities for future research in this area should “focus on optimising stimulation protocols and disentangling the underlying mechanism of action,” Dr. Wilbrink and colleagues wrote.
The study was funded by the Spinoza 2009 Lifetime Scientific Research Achievement Premium, the Netherlands Organisation for Scientific Research, the Dutch Ministry of Health (as part of a national provisional reimbursement program for promising new treatments), the NutsOhra Foundation from the Dutch Health Insurance Companies, and an unrestricted grant from Medtronic, all to Dr. Ferrari.

In the 30% ONS group, the mean attack frequency decreased from 15 (9.25 to 22.33) to 6.75 (1.5-16.5) with a median change of –6.5 (–10.83 to –0.08).
At weeks 21-24, the difference in median weekly mean attack frequency between the groups was –2.42 (–5.17 to 3.33).
The authors stated that, in both groups, ONS was “safe and well tolerated.” A total of 129 adverse events were reported in the 100% ONS group and 95 in the 30% ONS group, of which 17 and 9 were considered serious, respectively. The serious adverse events required a short hospital stay to resolve minor hardware issues. The adverse events most frequently observed were local pain, impaired wound healing, neck stiffness, and hardware damage.
Low intensity stimulation may be best
“The main limitation of the study comes from the difficulty in defining the electrical dose, which was not constant across patients within each group, but individually adjusted depending on the perception of the ONS-induced paraesthesia,” Denys Fontaine, MD, and Michel Lanteri-Minet, MD, both from Université Cote D’Azur in France, wrote in an accompanying editorial.
Given that the primary outcome did not differ significantly between the treatment groups, the editorialists stated that “the lowest stimulation intensity that induces paraesthesia is sufficient to obtain an effect in the patients who respond. Increasing the electrical dose or intensity does not seem to bring better efficacy and might even induce discomfort (painful paraesthesia or shock-like sensations) that might substantially reduce the tolerance of this approach.”
While the trial did not provide convincing evidence of high intensity ONS in medically intractable chronic cluster headache, the editorialists are otherwise optimistic about the findings: “… considering the significant difference between baseline and the end of the randomised stimulation phase in both groups (about half of the patients showed a 50% decrease in attack frequency), the findings of this study support the favourable results of previous real-world studies, and indicate that a substantial proportion of patients with intractable chronic cluster headache, although not all, could have their condition substantially improved by ONS.” Dr. Fontaine and Dr. Lanteri-Minet added that they hope that “these data will help health authorities to recognise the efficacy of ONS and consider its approval for use in patients with intractable chronic cluster headache.”
Priorities for future research in this area should “focus on optimising stimulation protocols and disentangling the underlying mechanism of action,” Dr. Wilbrink and colleagues wrote.
The study was funded by the Spinoza 2009 Lifetime Scientific Research Achievement Premium, the Netherlands Organisation for Scientific Research, the Dutch Ministry of Health (as part of a national provisional reimbursement program for promising new treatments), the NutsOhra Foundation from the Dutch Health Insurance Companies, and an unrestricted grant from Medtronic, all to Dr. Ferrari.
FROM LANCET NEUROLOGY
Are you at legal risk for speaking at conferences?
When Jerry Gardner, MD, and a junior colleague received the acceptance notification for their abstract to be presented at Digestive Diseases Week® (DDW) 2021, a clause in the mandatory participation agreement gave Dr. Gardner pause. It required his colleague, as the submitting author, to completely accept any and all legal responsibility for any claims that might arise out of their presentation.
The clause was a red flag to Dr. Gardner, president of Science for Organizations, a Mill Valley, Calif.–based consulting firm. The gastroenterologist and former head of the digestive diseases branch at the National Institute of Diabetes and Digestive and Kidney Diseases – who has made hundreds of presentations and had participated in DDW for 40 years – had never encountered such a broad indemnity clause.
This news organization investigated just how risky it is to make a presentation at a conference – more than a dozen professional societies were contacted. Although DDW declined to discuss its agreement, Houston health care attorney Rachel V. Rose said that Dr. Gardner was smart to be cautious. “I would not sign that agreement. I have never seen anything that broad and all encompassing,” she said.
The DDW requirement “means that participants must put themselves at great potential financial risk in order to present their work,” Dr. Gardner said. He added that he and his colleague would not have submitted an abstract had they known about the indemnification clause up front.
Dr. Gardner advised his colleague not to sign the DDW agreement. She did not, and both missed the meeting.
Speakers ‘have to be careful’
Dr. Gardner may be an exception. How many doctors are willing to forgo a presentation because of a concern about something in an agreement?
John Mandrola, MD, said he operates under the assumption that if he does not sign the agreement, then he won’t be able to give his presentation. He admits that he generally just signs them and is careful with his presentations. “I’ve never really paid much attention to them,” said Dr. Mandrola, a cardiac electrophysiologist in Louisville, Ky., and chief cardiology correspondent for Medscape.
Not everyone takes that approach. “I do think that people read them, but they also take them with a grain of salt,” said E. Magnus Ohman, MBBS, professor of medicine at Duke University, Durham, N.C. He said he’s pragmatic and regards the agreements as a necessary evil in a litigious nation. Speakers “have to be careful, obviously,” Dr. Ohman said in an interview.
Some argue that the requirements are not only fair but also understandable. David Johnson, MD, a former president of the American College of Gastroenterology, said he has never had questions about agreements for meetings he has been involved with. “To me, this is not anything other than standard operating procedure,” he said.
Presenters participate by invitation, noted Dr. Johnson, a professor of medicine and chief of gastroenterology at the Eastern Virginia Medical School, Norfolk, who is a contributor to this news organization. “If they stand up and do something egregious, I would concur that the society should not be liable,” he said.
Big asks, big secrecy
Even for those who generally agree with Dr. Johnson’s position, it may be hard to completely understand what’s at stake without an attorney.
Although many declined to discuss their policies, a handful of professional societies provided their agreements for review. In general, the agreements appear to offer broad protection and rights to the organizers and large liability exposure for the participants. Participants are charged with a wide range of responsibilities, such as ensuring against copyright violations and intellectual property infringement, and that they also agree to unlimited use of their presentations and their name and likeness.
The American Academy of Neurology, which held its meeting virtually in 2021, required participants to indemnify the organization against all “losses, expenses, damages, or liabilities,” including “reasonable attorneys’ fees.” Federal employees, however, could opt out of indemnification.
The American Society of Clinical Oncology said that it does not usually require indemnification from its meeting participants. However, a spokesperson noted that ASCO did require participants at its 2021 virtual meeting to abide by the terms of use for content posted to the ASCO website. Those terms specify that users agree to indemnify ASCO from damages related to posts.
The American Psychiatric Association said it does not require any indemnification but did not make its agreement available. The American Academy of Pediatrics also said it did not require indemnification but would not share its agreement.
An American Diabetes Association spokesperson said that “every association is different in what they ask or require from speakers,” but would not share its requirements.
The American Academy of Family Physicians, the American College of Obstetricians and Gynecologists, the American College of Physicians, and the Endocrine Society all declined to participate.
The organizations that withheld agreements “probably don’t want anybody picking apart their documents,” said Kyle Claussen, CEO of the Resolve Physician Agency, which reviews employment contracts and other contracts for physicians. “The more fair a document, the more likely they would be willing to disclose that, because they have nothing to hide,” he said.
‘It’s all on you’
Requiring indemnification for any and all aspects of a presentation appears to be increasingly common, said the attorneys interviewed for this article. As organizations repackage meeting presentations for sale, they put the content further out into the world and for a longer period, which increases liability exposure.
“If I’m the attorney for DDW, I certainly think I’d want to have this in place,” said Mr. Claussen.
“It’s good business sense for them because it reduces their risk,” said Courtney H. A. Thompson, an attorney with Fredrikson & Byron in Minneapolis, who advises regional and national corporations and ad agencies on advertising, marketing, and trademark law. She also works with clients who speak at meetings and who thus encounter meeting agreements.
Ms. Thompson said indemnity clauses have become fairly common over the past decade, especially as more companies and organizations have sought to protect trademarks, copyrights, and intellectual property and to minimize litigation costs.
A conference organizer “doesn’t want a third party to come after them for intellectual property, privacy, or publicity right infringement based on the participation of the customer or, in this case, the speaker,” said Ms. Thompson.
The agreements also reflect America’s litigation-prone culture.
Dean Fanelli, a patent attorney in the Washington, D.C., office of Cooley LLP, said the agreements he’s been asked to sign as a speaker increasingly seem “overly lawyerly.”
Two decades ago, a speaker might have been asked to sign a paragraph or a one-page form. Now “they often look more like formalized legal agreements,” Mr. Fanelli told this news organization.
The DDW agreement, for instance, ran four pages and contained 21 detailed clauses.
The increasingly complicated agreements “are a little over the top,” said Mr. Fanelli. But as an attorney who works with clients in the pharmaceutical industry, he said he understands that meeting organizers want to protect their rights.
DDW’s main indemnification clause requires the participant to indemnify DDW and its agents, directors, and employees “against any and all claims, demands, causes of action, losses, damages, liabilities, costs, and expenses,” including attorneys’ fees “arising out of a claim, action or proceeding” based on a breach or “alleged breach” by the participant.
“You’re releasing this information to them and then you’re also giving them blanket indemnity back, saying if there’s any type of intellectual property violation on your end – if you’ve included any type of work that’s protected, if this causes any problems – it’s all on you,” said Mr. Claussen.
Other potential pitfalls
Aside from indemnification, participation agreements can contain other potentially worrisome clauses, including onerous terms for cancellation and reuse of content without remuneration.
DDW requires royalty-free licensing of a speaker’s content; the organization can reproduce it in perpetuity without royalties. Many organizations have such a clause in their agreements, including the AAN and the American College of Cardiology.
ASCO’s general authorization form for meeting participants requires that they assign to ASCO rights to their content “perpetually, irrevocably, worldwide and royalty free.” Participants can contact the organization if they seek to opt out, but it’s not clear whether ASCO grants such requests.
Participants in the upcoming American Heart Association annual meeting can deny permission to record their presentation. But if they allow recording and do not agree to assign all rights and copyright ownership to the AHA, the work will be excluded from publication in the meeting program, e-posters, and the meeting supplement in Circulation.
Mr. Claussen said granting royalty-free rights presents a conundrum. Having content reproduced in various formats “might be better for your personal brand,” but it’s not likely to result in any direct compensation and could increase liability exposure, he said.
How presenters must prepare
Mr. Claussen and Ms. Rose said speakers should be vigilant about their own rights and responsibilities, including ensuring that they do not violate copyrights or infringe on intellectual property rights.
“I would recommend that folks be meticulous about what is in their slide deck and materials,” said Ms. Thompson. He said that presenters should be sure they have the right to share material. Technologies crawl the internet seeking out infringement, which often leads to cease and desist letters from attorneys, she said.
It’s better to head off such a letter, Ms. Thompson said. “You need to defend it whether or not it’s a viable claim,” and that can be costly, she said.
Both Ms. Thompson and Mr. Fanelli also warn about disclosing anything that might be considered a trade secret. Many agreements prohibit presenters from engaging in commercial promotion, but if a talk includes information about a drug or device, the manufacturer will want to review the presentation before it’s made public, said Mr. Fanelli.
Many organizations prohibit attendees from photographing, recording, or tweeting at meetings and often require speakers to warn the audience about doing so. DDW goes further by holding presenters liable if someone violates the rule.
“That’s a huge problem,” said Dr. Mandrola. He noted that although it might be easy to police journalists attending a meeting, “it seems hard to enforce that rule amongst just regular attendees.”
Accept or negotiate?
Individuals who submit work to an organization might feel they must sign an agreement as is, especially if they are looking to advance their career or expand knowledge by presenting work at a meeting. But some attorneys said it might be possible to negotiate with meeting organizers.
“My personal opinion is that it never hurts to ask,” said Ms. Thompson. If she were speaking at a legal conference, she would mark up a contract and “see what happens.” The more times pushback is accepted – say, if it works with three out of five speaking engagements – the more it reduces overall liability exposure.
Mr. Fanelli, however, said that although he always reads over an agreement, he typically signs without negotiating. “I don’t usually worry about it because I’m just trying to talk at a particular seminar,” he said.
Prospective presenters “have to weigh that balance – do you want to talk at a seminar, or are you concerned about the legal issues?” said Mr. Fanelli.
If in doubt, talk with a lawyer.
“If you ever have a question on whether or not you should consult an attorney, the answer is always yes,” said Mr. Claussen. It would be “an ounce of prevention,” especially if it’s just a short agreement, he said.
Dr. Ohman, however, said that he believed “it would be fairly costly” and potentially unwieldy. “You can’t litigate everything in life,” he added.
As for Dr. Gardner, he said he would not be as likely to attend DDW in the future if he has to agree to cover any and all liability. “I can’t conceive of ever agreeing to personally indemnify DDW in order to make a presentation at the annual meeting,” he said.

“I would recommend that folks be meticulous about what is in their slide deck and materials,” said Ms. Thompson. He said that presenters should be sure they have the right to share material. Technologies crawl the internet seeking out infringement, which often leads to cease and desist letters from attorneys, she said.
It’s better to head off such a letter, Ms. Thompson said. “You need to defend it whether or not it’s a viable claim,” and that can be costly, she said.
Both Ms. Thompson and Mr. Fanelli also warn about disclosing anything that might be considered a trade secret. Many agreements prohibit presenters from engaging in commercial promotion, but if a talk includes information about a drug or device, the manufacturer will want to review the presentation before it’s made public, said Mr. Fanelli.
Many organizations prohibit attendees from photographing, recording, or tweeting at meetings and often require speakers to warn the audience about doing so. DDW goes further by holding presenters liable if someone violates the rule.
“That’s a huge problem,” said Dr. Mandrola. He noted that although it might be easy to police journalists attending a meeting, “it seems hard to enforce that rule amongst just regular attendees.”
Accept or negotiate?
Individuals who submit work to an organization might feel they must sign an agreement as is, especially if they are looking to advance their career or expand knowledge by presenting work at a meeting. But some attorneys said it might be possible to negotiate with meeting organizers.
“My personal opinion is that it never hurts to ask,” said Ms. Thompson. If she were speaking at a legal conference, she would mark up a contract and “see what happens.” The more times pushback is accepted – say, if it works with three out of five speaking engagements – the more it reduces overall liability exposure.
Mr. Fanelli, however, said that although he always reads over an agreement, he typically signs without negotiating. “I don’t usually worry about it because I’m just trying to talk at a particular seminar,” he said.
Prospective presenters “have to weigh that balance – do you want to talk at a seminar, or are you concerned about the legal issues?” said Mr. Fanelli.
If in doubt, talk with a lawyer.
“If you ever have a question on whether or not you should consult an attorney, the answer is always yes,” said Mr. Claussen. It would be “an ounce of prevention,” especially if it’s just a short agreement, he said.
Dr. Ohman, however, said that he believed “it would be fairly costly” and potentially unwieldy. “You can’t litigate everything in life,” he added.
As for Dr. Gardner, he said he would not be as likely to attend DDW in the future if he has to agree to cover any and all liability. “I can’t conceive of ever agreeing to personally indemnify DDW in order to make a presentation at the annual meeting,” he said.
