Playing table tennis, also known as ping-pong, appears to improve motor symptoms in patients with Parkinson’s disease, new research suggests. The results of a small pilot study show that table ping-pong is a safe and effective rehabilitative intervention for patients with Parkinson’s disease that can be easily introduced, study investigator Shinsuke Fujioka, MD, Department of Neurology, Fukuoka University, Japan, told Medscape Medical News.

He emphasized that any rehabilitation for patients with Parkinson’s disease could be beneficial, especially during the early stages of their illness. “The most important thing is that patients have fun when doing rehabilitation.”

The findings were released February 25 ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology. The AAN canceled the meeting and released abstracts and access to presenters for press coverage.
 

All exercise beneficial

The idea of studying ping-pong as a therapy for patients with Parkinson’s disease originated when Dr. Fujioka heard about a patient who used a cane but no longer needed it after taking up the exercise as a weekly rehabilitation therapy.

“It’s apparent that the exercise can improve motor function of Parkinson’s disease. However, to date, the effects of the sport have not been well investigated for this patient population, so our study aimed to disclose the effects that table tennis can bring to patients with Parkinson’s disease,” said Dr. Fujioka.

The study included 12 patients with Parkinson’s disease – 10 women and two men. Mean age at disease onset was 67 years, and mean disease duration was 7 years. Mean stage on the Hoehn & Yahr scale, which assesses severity of Parkinson’s disease symptoms, was three, so most patients had balance problems.

Study participants played ping-pong at once-weekly 5-hour sessions that included rest breaks whenever they felt it was necessary.

Researchers assessed participants using the Unified Parkinson’s Disease Rating Scale (UPDRS) part I-IV. Parts II and III assess motor function whereas parts I and IV evaluate nonmotor function and motor complications, respectively.

The main motor symptoms of Parkinson’s disease include bradykinesia and muscle rigidity, tremor, and postural instability.

Researchers also assessed participants using the Montreal Cognitive Assessment (MoCA), Frontal Assessment Battery (FAB), Self-Rating Depression Scale (SDS), and Apathy scale.

Results showed that UPDRS part II significantly improved at 3 and 6 months (both P < 0.001), as did UPDRS part III (P = 0.002 at 3 months; P < 0.001 at 6 months).

Dr. Fujioka speculated, “twisting axial muscles when hitting a ping-pong ball may be the most efficacious for patients, especially for bradykinesia and balance problems.”
 

Significant improvement

Such findings may not be that surprising. Dr. Fujioka pointed to other rehabilitation therapies such as tai chi or tango that may also improve Parkinson’s disease motor symptoms.

For UPDRS part II, subscores of speech, saliva and drooling, dressing, handwriting, doing hobbies and other activities, getting out of bed, a car, or a deep chair, and walking and balance, significantly improved.

In addition, for UPDRS part III, subscores of facial expression, rigidity, postural stability, posture, bradykinesia, and kinetic tremor of the hands also significantly improved.

As for nonmotor symptoms such as mood, anxiety, depression, and apathy assessed in UPDRS part I, scores did not significantly change, which was also the case for part IV.

However, Dr. Fujioka pointed out that patient scores didn’t worsen. “Given the nature of disease, not worsening of nonmotor features can potentially be a good effect of the sport.” MoCA, FAB, SDS, and Apathy scale scores also did not change.

Dr. Fujioka noted that all participants enjoyed the table tennis rehabilitation, and “gradually smiled more during the study period.” All study participants continued the table tennis rehabilitation after the 6-month program.

Dr. Fujioka noted that although patients with Parkinson’s disease often have difficulty moving in a front-to-back direction, they can move relatively easily in a lateral direction.

“In that sense, table tennis is suitable for them,” he said. However, he added, court tennis, handball, and badminton may not be suitable for most patients with Parkinson’s disease.

One patient suffered a fall and another backache. Dr. Fujioka cautioned that more frequent ping-pong playing might increase the risk of adverse events.

He also suggests patients with Parkinson’s disease have their bone density checked before starting regular rehabilitation exercise as they are at increased risk for osteoporosis.

The investigators are currently organizing a prospective, multicenter randomized study to compare the effectiveness of table tennis with conventional rehabilitation and the Lee Silverman Voice Treatment, which is designed to increase vocal intensity in patients with Parkinson’s disease.
 

Fun, engaging

Commenting on the findings, Cynthia Comella, MD, professor emeritus, Neurological Sciences, Rush University Medical Center, New Philadelphia, Ohio, said ping-pong is a “fun and engaging” exercise for patients with Parkinson’s disease. Dr. Comella noted prior studies have shown many types of exercise are beneficial for patients with Parkinson’s disease “provided that they continue” with it.

In that regard, these new results are “promising,” she said. “It may be that this type of community generating, fun exercise would lead to a continuation of the exercise after a study is completed.”

A controlled trial that includes a post-study follow-up to evaluate compliance and continued benefit is needed, she said.

Purchase of equipment, including tables, rackets, and balls, was possible through funds donated by Hisako Kobayashi-Levin, which provides Murakami Karindoh Hospital with an annual fund to improve the quality of their rehabilitation program. The authors reported no relevant financial relationships.

Hypersomnolence, or excessive daytime sleepiness, in older adults is a risk factor for developing several serious medical conditions, including hypertension, heart disease, cancer, and diabetes, new research suggests. A study of almost 11,000 participants shows those who reported excessive sleepiness were twice as likely as their nonsleepy counterparts to develop these conditions. Hypersomnolence was also linked to development of musculoskeletal and connective tissue conditions.

“Paying attention to sleepiness in older adults could help doctors predict and prevent future medical conditions,” study investigator Maurice M. Ohayon, MD, PhD, Stanford University, California, said in a news release.

The findings were released March 1 ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology. The AAN canceled the meeting and released abstracts and access to presenters for press coverage.
 

Early warning sign

Prior research has suggested an association between hypersomnolence and several psychiatric disorders, as well as cognitive decline and Alzheimer’s disease. However, its role in the development of other medical conditions is not as well studied.

The current investigation included 10,930 adults who were interviewed by phone on two separate occasions 3 years apart. At the second interview, 3,701 participants were at least 65 years old and 59% were women.

About 23% of the elderly participants reported hypersomnolence in the first interview and 24% reported it in the second interview. Of these individuals, 41% said during the first and second interviews that excessive daytime sleepiness was a chronic problem.

After adjusting for gender and obstructive sleep apnea status, participants who reported hypersomnolence in the first interview had more than a twofold greater risk of developing diabetes (relative risk [RR], 2.3; 95% CI, 1.5 - 3.4) or hypertension (RR, 2.3; 95% CI, 1.5 - 3.4) 3 years later than those who did not report this problem. They were also twice as likely to develop cancer (RR, 2.0; 95% CI, 1.1 - 3.8).

Of the 840 participants who reported hypersomnolence at the first interview, 52 (6.2%) developed diabetes compared with 74 (2.9%) who did not have excessive daytime sleepiness. Twenty (2.4%) individuals who reported hypersomnolence developed cancer compared with 21 (0.8%) who did not have it. Chronic hypersomnolence was associated with a greater than twofold increased risk of developing heart disease (RR, 2.5; 95% CI, 1.8 - 3.4).

Those who reported hypersomnolence at the second interview also were 50% more likely to have diseases of the musculoskeletal system and connective tissue, such as arthritis, tendinitis, and lupus, than their peers who did not have excessive daytime sleepiness.

The findings suggest that hypersomnolence in the elderly “can be an early sign of a developing medical condition,” the investigators wrote.

A limitation of the study is that it relied on participants’ memories rather than monitoring their sleep length and quality and daytime sleepiness in a sleep clinic, they noted.

Sleep as a vital sign?

Commenting on the findings, Harly Greenberg, MD, medical director at the Northwell Health Sleep Disorders Center, New York City, called the study “informative.”

However, because the findings were associations, “the study does not necessarily indicate that hypersomnolence itself is causal for these conditions. Rather excessive sleepiness may be a marker of sleep disorders that can cause sleepiness as well as contribute to the risk of these medical conditions,” said Dr. Greenberg, who was not involved with the research.

“The takeaway point from this study is that excessive sleepiness should not be ignored. Not only does it impair quality of life, daytime function, and vigilance and increase risk of sleepiness-related accidents, it may also be a marker for serious sleep disorders that can increase risk for medical disorders,” he said.

Also commenting on the study, Nathaniel Watson, MD, professor of neurology at the University of Washington (UW) and director of the UW Medicine Sleep Clinic, said it is “not surprising” that excessive daytime sleepiness might contribute to diabetes, hypertension, and other diseases.

“Sleep is something we spend a third of our lives doing. It impacts nearly every aspect of human physiology and we have a lot of basic science and epidemiologic research that shows when sleep is either inadequate or of poor quality or not timed correctly it can be associated with some of these untoward health outcomes,” said Watson, who is a past president of the American Academy of Sleep Medicine.

“This research just provides further evidence in support of the importance of sleep for overall health and well-being,” he added.

Asking patients about sleepiness, sleep, or sleep quality should be a “vital sign just like temperature, blood pressure, weight, and these other measures,” Dr. Watson said.

The study was supported by the Arrillaga Foundation. Drs. Ohayon, Greenberg, and Watson have reported no relevant financial relationships.

A healthier heart in young adulthood could mean fewer cognitive problems later in life, new research suggests. New findings from the Coronary Artery Risk Development in Young Adults (CARDIA) study show that individuals who had better cardiovascular health in their 20s scored higher on tests of thinking and memory 30 years later than their peers who had poorer cardiovascular health as young adults.

“We have learned that midlife vascular risk factors, rather than risk factors in older age, are particularly associated with cognition in older age,” study author Farzaneh Sorond, MD, PhD, Northwestern University Feinberg School of Medicine, Chicago, Illinois, told Medscape Medical News

“Our findings from the CARDIA study expand this knowledge and show that vascular health during young adulthood, rather than midlife, is also specifically associated with brain vascular health and cognitive function” in later life, Dr. Sorond said.

“These results indicate that people need to pay close attention to their health even in their early 20s,” she added in a statement.

The findings were released February 26 ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology. The AAN canceled the meeting and released abstracts and access to presenters for press coverage.
 

Early prevention key

The analysis examined data from 189 participants (45% women, 45% black) in the CARDIA study who were followed for 30 years. The mean age at baseline was 24 years.

Vascular risk factors were assessed eight times during the 30-year study period. A cardiovascular health score (range, 0 – 10) was calculated on the basis of smoking status, body mass index, blood pressure, total cholesterol level, and fasting glucose level.

At the final assessment, which was conducted 30 years after baseline, dynamic cerebral autoregulation was calculated as the transfer function phase of the spontaneous oscillations in blood pressure and flow velocity in the middle cerebral artery using transcranial Doppler ultrasound.

Good for the heart, good for the brain

Commenting on the findings, Rebecca Edelmayer, PhD, director of scientific engagement for the Alzheimer’s Association, said that the longitudinal study adds to the growing body of research showing that “what is good for the heart is also good for the brain.”

“This is still a relatively small study, and larger studies have been published that show similar results,” said Dr. Edelmayer, who was not involved with the research.

She noted that results of the large SPRINT-MIND trial, published last year in JAMA and reported by Medscape Medical News, “provided the strongest evidence to date about reducing risk of mild cognitive impairment through the management of high blood pressure.”

The Alzheimer’s Association has provided seed funding for SPRINT-MIND 2.0, a 2-year extension of the study to evaluate whether intensive blood pressure management reduces risk for all-cause dementia.

Support for the current study was provided by the National Institutes of Health, the National Heart, Lung, and Blood Institute, the University of Alabama at Birmingham, Northwestern University, the University of Minnesota, and the Kaiser Foundation Research Institute. Drs. Sorond and Edelmayer have reported no relevant financial relationships.

“We have learned that midlife vascular risk factors, rather than risk factors in older age, are particularly associated with cognition in older age,” study author Farzaneh Sorond, MD, PhD, Northwestern University Feinberg School of Medicine, Chicago, Illinois, told Medscape Medical News

“Our findings from the CARDIA study expand this knowledge and show that vascular health during young adulthood, rather than midlife, is also specifically associated with brain vascular health and cognitive function” in later life, Dr. Sorond said.

“These results indicate that people need to pay close attention to their health even in their early 20s,” she added in a statement.

The findings were released February 26 ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology. The AAN canceled the meeting and released abstracts and access to presenters for press coverage.
 

Early prevention key

The analysis examined data from 189 participants (45% women, 45% black) in the CARDIA study who were followed for 30 years. The mean age at baseline was 24 years.

Vascular risk factors were assessed eight times during the 30-year study period. A cardiovascular health score (range, 0 – 10) was calculated on the basis of smoking status, body mass index, blood pressure, total cholesterol level, and fasting glucose level.

At the final assessment, which was conducted 30 years after baseline, dynamic cerebral autoregulation was calculated as the transfer function phase of the spontaneous oscillations in blood pressure and flow velocity in the middle cerebral artery using transcranial Doppler ultrasound.

Good for the heart, good for the brain

Commenting on the findings, Rebecca Edelmayer, PhD, director of scientific engagement for the Alzheimer’s Association, said that the longitudinal study adds to the growing body of research showing that “what is good for the heart is also good for the brain.”

“This is still a relatively small study, and larger studies have been published that show similar results,” said Dr. Edelmayer, who was not involved with the research.

She noted that results of the large SPRINT-MIND trial, published last year in JAMA and reported by Medscape Medical News, “provided the strongest evidence to date about reducing risk of mild cognitive impairment through the management of high blood pressure.”

The Alzheimer’s Association has provided seed funding for SPRINT-MIND 2.0, a 2-year extension of the study to evaluate whether intensive blood pressure management reduces risk for all-cause dementia.

Support for the current study was provided by the National Institutes of Health, the National Heart, Lung, and Blood Institute, the University of Alabama at Birmingham, Northwestern University, the University of Minnesota, and the Kaiser Foundation Research Institute. Drs. Sorond and Edelmayer have reported no relevant financial relationships.

Patients with a mild traumatic brain injury (mTBI) who are exposed to blue light experience less depression and fewer cognitive and other concussion-related symptoms than those exposed to a placebo light, a new study has found. Exposure to blue light in the morning through a special device may be a “critical factor” in resetting the circadian rhythm and helping people who have suffered a concussion, author William D. “Scott” Killgore, MD, professor of psychiatry, psychology, and medical imaging, the University of Arizona College of Medicine, Tucson, told Medscape Medical News.

“This is very new, so I wouldn’t say it’s the treatment of choice, but we should start looking at using this system as a nonpharmacologic way to perhaps help patients recover faster from a concussion,” he said.

The findings were released March 2 ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology. The AAN canceled the meeting and released abstracts and access to presenters for press coverage.

About half of patients with a concussion experience sleep problems, including problems falling asleep, staying asleep, and waking up in the middle of the night, said Dr. Killgore.

Poor sleep interrupts the brain’s repair mechanism. “Sleep is important for cleaning out the neurotoxins that build up in your brain during the day. Sleep also helps build oligodendrocyte precursor cells that provide insulation around nerve cells,” he said.
 

Master clock

Blue light stimulates receptors in the back of the retina that respond only to this wavelength of light, said Dr. Killgore. “It specifically projects to an area in the hypothalamus – essentially the brain’s master clock – that regulates your sleep-wake schedules. So exposure to that bright light essentially resets your circadian rhythm.”

That master clock involves regulating the brain’s production of melatonin. Morning exposure to blue light shifts that production to facilitate sleep at the appropriate time.

The ideal time to be exposed to blue light is from about 8:00 to 11:00 AM. “Timing is critical,” said Dr. Killgore. “If you get light at the wrong time, it will reset your circadian rhythm in the wrong direction.”

Previous research has shown that exposure to blue light leads to improved sleep, which is widely believed to lead to improved mood.

A separate study conducted by Dr. Killgore and colleagues that involved another group of mTBI patients was recently published in Neurobiology of Disease. That study showed that the participants who received blue light experienced a shift in circadian timing of about an hour. “They were going to sleep an hour earlier and waking up an hour earlier,” said Dr. Killgore.

The blue light also appeared to change brain structure and brain function, among other things, he said.

The current study included 35 patients who had suffered an mTBI within the previous 18 months. Most injuries were sports related and occurred while playing football or soccer or riding a bike.

Participants were randomly assigned to use a device fitted with a blue LED light (peak wavelength, 469 nm) or one fitted with an amber-colored LED light. They were instructed to use the device every morning for 30 minutes within 2 hours of waking.

The blue-light group comprised five men and 12 women (mean age, 25.5 years). The amber-light group comprised eight men and 10 women (mean age, 26.3 years).

Researchers told participants only that the study was exploring various aspects of light. “Subjects didn’t know if they were getting a control or active device,” said Dr. Killgore.

Researchers used the Beck Depression Inventory (BDI) to evaluate depression symptoms and the Rivermead Post-Concussion Symptom Questionnaire (RPCSQ). This 16-item questionnaire assesses symptoms in the acute stage as well as those that are more chronic.

After 6 weeks, the blue-light group had lower scores on the BDI compared to the amber-light group (P = .005).

“We found that in the amber-light group, there was essentially no change in terms of depression,” said Dr. Killgore. “But those who got the blue light showed a significant reduction in depressive symptoms, about a 22% decline overall relative to baseline, so a nice drop in overall depression.”

Changes in BDI scores were significantly positively associated with changes in the total chronic symptom score (P = .002) in the blue-light group but not the amber-light group. “Those who got blue light showed a significant reduction in the number of symptoms associated with concussion whereas those who got the amber light stayed the same,” said Dr. Killgore.

There were similar findings for somatic symptoms, such as headache and pain (P = .031), and for cognitive symptoms (P = .014) in the blue-light group.

“These subjects were having fewer problems remembering and paying attention, so their concentration seemed to be improving, at least subjectively,” commented Dr. Killgore.

There was no significant benefit from the blue light for emotional symptoms. “There was a decline, but it wasn’t statistically significant, even though there was a decline in depression,” said Dr. Killgore.

This, he explained, could be due to the small sample size and the greater sensitivity of the BDI for emotional symptoms relative to the RPCSQ. “The BDI has 21 items that are all focused on aspects of depression, whereas the RPCSQ only asks one item for depression and one item for irritability/anger.”

Less daytime sleepiness

The researchers also found a significant improvement in daytime sleepiness. “Subjects were much less sleepy by the end of the study if they got blue light than if they got amber light,” said Dr. Killgore.

Participants wore an actigraphy device that took sleep measurements. Early results indicate that blue-light recipients were getting more sleep by the end of the study.

Researchers are now analyzing additional data to see whether the improvements in depression and post-concussion symptoms are linked to improved sleep. They also gathered data from brain imaging that will be analyzed at a later date.

Dr. Killgore and his colleagues aim to determine what distinguishes people who respond to blue-light therapy from those who don’t. “We want to know what it is that would allow some people to be more responsive than others, so we’re going to be exploring skin color, eye color, genetic factors, and other factors,” he said.

They’re also conducting a study of blue-light therapy in patients with posttraumatic stress disorder, 90% of whom have sleep problems.

“This is quite fascinating,” said Dr. Killgore. “It looks like if you get blue light after your treatment, the treatment sticks better than if you didn’t get the blue light. We think that sleep is probably playing an important role in that.”

Several light devices are available, ranging in price from about $100 to $200.

Commenting on the research, concussion expert Frank Conidi, MD, director of the Florida Center for Headache and Sports Neurology, Port St. Lucie, said the study is interesting from a number of perspectives.

For one thing, it shows that blue-light therapy “provides an inexpensive and minimally invasive way to treat concussion,” he said.

Dr. Conidi said he would recommend blue-light therapy for concussion patients. “I could see neurology practices offering the device to patients as an in-office treatment or to take home for a small fee. I think athletes would be quite receptive to this, as they’re always looking for nonpharmacological ways to treat concussion.”

Dr. Conidi noted that the new results are consistent with other studies that show that decreased depression and improved sleep help with somatic symptoms.

From a research perspective, the study provides a “stepping stone” for larger trials, said Dr. Conidi. He would like to see more studies of acute concussion, such as studies as to whether the therapy shortens the duration of symptoms.

“I would also like to see controlled studies on headache and vestibular symptoms, which are the two most common,” he said.

The study was funded by the US Department of Defense. Killgore and Conidi have disclosed no relevant financial relationships.

The take-home message from a growing number of recent COVID-19 case reports is that the infection might be far more than a respiratory disease.

Although a cause-and-effect relationship is unknown, people with the virus have presented with or developed heart disease, acute liver injury, ongoing GI issues, skin manifestations, neurologic damage, and other problems, especially among sicker people.

For example, French physicians described an association with encephalopathy, agitation, confusion, and corticospinal tract signs among 58 people hospitalized with acute respiratory distress (N Engl J Med. 2020 Apr 15. doi: 10.1056/NEJMc2008597).

In particular, Yale New Haven (Conn.) Hospital is dealing with unexpected complications up close. Almost half of the beds there are occupied by COVID-19 patients. Over 100 people are in the ICU, and almost 70 intubated. Of the more than 750 COVID admissions so far, only about 350 have been discharged. “Even in a bad flu season, you never see something like this; it’s just unheard of,” said Harlan Krumholz, MD, a Yale cardiologist and professor of medicine helping lead the efforts there.
 

Kidney injuries prominent

“When they get to the ICU, we are seeing lots of people with acute kidney injuries; lots of people developing endocrine problems; people having blood sugar control issues, coagulation issues, blood clots. We are just waking up to the wide range of ways this virus can affect people. Our ignorance is profound,” Dr. Krumholz said, but physicians “recognize that this thing has the capability of attacking almost every single organ system, and it may or may not present with respiratory symptoms.”

It’s a similar story at Mt. Sinai South Nassau, a hospital in Oceanside, N.Y. “We’ve seen a lot of renal injury in people having complications, a lot of acute dialysis,” but it’s unclear how much is caused by the virus and how much is simply because people are so sick, said Aaron Glatt, MD, infectious disease professor and chair of medicine at the hospital. However, he said things are looking brighter than at Yale.

“We are not seeing the same level of increase in cases that we had previously, and we are starting to see extubations and discharges. We’ve treated a number of patients with plasma therapy, and hopefully that will be of benefit. We’ve seen some response to” the immunosuppressive “tocilizumab [Actemra], and a lot of response to very good respiratory therapy. I think we are starting to flatten the curve,” Dr. Glatt said.
 

“Look for tricky symptoms”

The growing awareness of COVID’s protean manifestations is evident in Medscape’s Consult forum, an online community where physicians and medical students share information and seek advice; there’s been over 200 COVID-19 cases and questions since January.

Early on, traffic was mostly about typical pulmonary presentations, but lately it’s shifted to nonrespiratory involvement. Physicians want to know if what they are seeing is related to the virus, and if other people are seeing the same things.

There’s a case on Consult of a 37-year-old man with stomach pain, vomiting, and diarrhea, but no respiratory symptoms and a positive COVID test. A chest CT incidental to his abdominal scan revealed significant bilateral lung involvement.

A 69-year-old woman with a history of laparotomy and new onset intestinal subocclusion had only adhesions on a subsequent exploratory laparotomy, and was doing okay otherwise. She suddenly went into respiratory failure with progressive bradycardia and died 3 days later. Aspiration pneumonia, pulmonary embolism, and MI had been ruled out. “The pattern of cardiovascular failure was in favor of myocarditis, but we don’t have any other clue,” the physician said after describing a second similar case.

Another doctor on the forum reported elevated cardiac enzymes without coronary artery obstruction in a positive patient who went into shock, with an ejection fraction of 40% and markedly increased heart wall thickness, but no lung involvement. There are also two cases of idiopathic thrombocytopenia without fever of hypoxia.

An Italian gastroenterologist said: “Look for tricky symptoms.” Expand “patient history, asking about the sudden occurrence of dysgeusia and/or anosmia. These symptoms have become my guiding diagnostic light” in Verona. “Most patients become nauseated, [and] the taste of any food is unbearable. When I find these symptoms by history, the patient is COVID positive 100%.”
 

‘Make sure that they didn’t die in vain’

There was interest in those and other reports on Consult, and comments from physicians who have theories, but no certain answers about what is, and is not, caused by the virus.

Direct viral attack is likely a part of it, said Stanley Perlman, MD, PhD, a professor of microbiology and immunology at the University of Iowa, Iowa City.

The ACE2 receptor the virus uses to enter cells is common in many organs, plus there were extrapulmonary manifestations with severe acute respiratory syndrome (SARS), another pandemic caused by a zoonotic coronavirus almost 20 years ago. At least with SARS, “many organs were infected when examined at autopsy,” he said.

The body’s inflammatory response is almost certainly also in play. Progressive derangements in inflammatory markers – C-reactive protein, D-dimer, ferritin – correlate with worse prognosis, and “the cytokine storm that occurs in these patients can lead to a degree of encephalopathy, myocarditis, liver impairment, and kidney impairment; multiorgan dysfunction, in other words,” said William Shaffner, MD, a professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center, Nashville, Tenn.

But in some cases, the virus might simply be a bystander to an unrelated disease process; in others, the experimental treatments being used might cause problems. Indeed, cardiology groups recently warned of torsade de pointes – a dangerously abnormal heart rhythm – with hydroxychloroquine and azithromycin.

“We think it’s some combination,” but don’t really know, Dr. Krumholz said. In the meantime, “we are forced to treat patients by instinct and first principles,” and long-term sequelae are unknown. “We don’t want to be in this position for long.”

To that end, he said, “this is the time for us all to hold hands and be together because we need to learn rapidly from each other. Our job is both to care for the people in front of us and make sure that they didn’t die in vain, that the experience they had is funneled into a larger set of data to make sure the next person is better off.”

The take-home message from a growing number of recent COVID-19 case reports is that the infection might be far more than a respiratory disease.

Although a cause-and-effect relationship is unknown, people with the virus have presented with or developed heart disease, acute liver injury, ongoing GI issues, skin manifestations, neurologic damage, and other problems, especially among sicker people.

For example, French physicians described an association with encephalopathy, agitation, confusion, and corticospinal tract signs among 58 people hospitalized with acute respiratory distress (N Engl J Med. 2020 Apr 15. doi: 10.1056/NEJMc2008597).

In particular, Yale New Haven (Conn.) Hospital is dealing with unexpected complications up close. Almost half of the beds there are occupied by COVID-19 patients. Over 100 people are in the ICU, and almost 70 intubated. Of the more than 750 COVID admissions so far, only about 350 have been discharged. “Even in a bad flu season, you never see something like this; it’s just unheard of,” said Harlan Krumholz, MD, a Yale cardiologist and professor of medicine helping lead the efforts there.
 

Kidney injuries prominent

“When they get to the ICU, we are seeing lots of people with acute kidney injuries; lots of people developing endocrine problems; people having blood sugar control issues, coagulation issues, blood clots. We are just waking up to the wide range of ways this virus can affect people. Our ignorance is profound,” Dr. Krumholz said, but physicians “recognize that this thing has the capability of attacking almost every single organ system, and it may or may not present with respiratory symptoms.”

It’s a similar story at Mt. Sinai South Nassau, a hospital in Oceanside, N.Y. “We’ve seen a lot of renal injury in people having complications, a lot of acute dialysis,” but it’s unclear how much is caused by the virus and how much is simply because people are so sick, said Aaron Glatt, MD, infectious disease professor and chair of medicine at the hospital. However, he said things are looking brighter than at Yale.

“We are not seeing the same level of increase in cases that we had previously, and we are starting to see extubations and discharges. We’ve treated a number of patients with plasma therapy, and hopefully that will be of benefit. We’ve seen some response to” the immunosuppressive “tocilizumab [Actemra], and a lot of response to very good respiratory therapy. I think we are starting to flatten the curve,” Dr. Glatt said.
 

“Look for tricky symptoms”

The growing awareness of COVID’s protean manifestations is evident in Medscape’s Consult forum, an online community where physicians and medical students share information and seek advice; there’s been over 200 COVID-19 cases and questions since January.

Early on, traffic was mostly about typical pulmonary presentations, but lately it’s shifted to nonrespiratory involvement. Physicians want to know if what they are seeing is related to the virus, and if other people are seeing the same things.

There’s a case on Consult of a 37-year-old man with stomach pain, vomiting, and diarrhea, but no respiratory symptoms and a positive COVID test. A chest CT incidental to his abdominal scan revealed significant bilateral lung involvement.

A 69-year-old woman with a history of laparotomy and new onset intestinal subocclusion had only adhesions on a subsequent exploratory laparotomy, and was doing okay otherwise. She suddenly went into respiratory failure with progressive bradycardia and died 3 days later. Aspiration pneumonia, pulmonary embolism, and MI had been ruled out. “The pattern of cardiovascular failure was in favor of myocarditis, but we don’t have any other clue,” the physician said after describing a second similar case.

Another doctor on the forum reported elevated cardiac enzymes without coronary artery obstruction in a positive patient who went into shock, with an ejection fraction of 40% and markedly increased heart wall thickness, but no lung involvement. There are also two cases of idiopathic thrombocytopenia without fever of hypoxia.

An Italian gastroenterologist said: “Look for tricky symptoms.” Expand “patient history, asking about the sudden occurrence of dysgeusia and/or anosmia. These symptoms have become my guiding diagnostic light” in Verona. “Most patients become nauseated, [and] the taste of any food is unbearable. When I find these symptoms by history, the patient is COVID positive 100%.”
 

‘Make sure that they didn’t die in vain’

There was interest in those and other reports on Consult, and comments from physicians who have theories, but no certain answers about what is, and is not, caused by the virus.

Direct viral attack is likely a part of it, said Stanley Perlman, MD, PhD, a professor of microbiology and immunology at the University of Iowa, Iowa City.

The ACE2 receptor the virus uses to enter cells is common in many organs, plus there were extrapulmonary manifestations with severe acute respiratory syndrome (SARS), another pandemic caused by a zoonotic coronavirus almost 20 years ago. At least with SARS, “many organs were infected when examined at autopsy,” he said.

The body’s inflammatory response is almost certainly also in play. Progressive derangements in inflammatory markers – C-reactive protein, D-dimer, ferritin – correlate with worse prognosis, and “the cytokine storm that occurs in these patients can lead to a degree of encephalopathy, myocarditis, liver impairment, and kidney impairment; multiorgan dysfunction, in other words,” said William Shaffner, MD, a professor of preventive medicine and infectious diseases at Vanderbilt University Medical Center, Nashville, Tenn.

But in some cases, the virus might simply be a bystander to an unrelated disease process; in others, the experimental treatments being used might cause problems. Indeed, cardiology groups recently warned of torsade de pointes – a dangerously abnormal heart rhythm – with hydroxychloroquine and azithromycin.

“We think it’s some combination,” but don’t really know, Dr. Krumholz said. In the meantime, “we are forced to treat patients by instinct and first principles,” and long-term sequelae are unknown. “We don’t want to be in this position for long.”

STOWE, VT. – A large and growing number of medications is available for the acute treatment of migraine. Effective acute treatment enables patients to re-engage in their work and other daily activities, as well as reducing the likelihood that their disease will progress from episodic to chronic migraine. Considering appropriate routes of delivery, assessing efficacy and tolerability, and communicating well with the patient are essential components in the acute treatment of migraine, according to Barbara L. Nye, MD, assistant professor of neurology at the Geisel School of Medicine at Dartmouth, Hanover, N.H.. Dr. Nye discussed the acute treatment of migraine at the annual meeting of the Headache Cooperative of New England.

Choosing an initial treatment

Nonspecific medications are perhaps the first treatments to consider for a patient with acute migraine. This class includes NSAIDs such as naproxen sodium, piroxicam, diclofenac, celecoxib, and indomethacin. Emerging data indicate that some NSAIDs are associated with an increased risk of stroke, which is an important consideration as the population ages, said Dr. Nye. Other nonspecific options are neuroleptics such as prochlorperazine, metoclopramide, promethazine, and chlorpromazine. Many neuroleptics have sedative effects, however, so they do not necessarily help a patient return to function. Nevertheless, these drugs can be good rescue medications, said Dr. Nye.

Triptans are effective in the acute treatment of migraine, and seven drugs in this class are available. Most, such as rizatriptan, almotriptan, eletriptan, naratriptan, and frovatriptan, are available only as tablets. Other routes of delivery are available, however. Sumatriptan, for example, is available in injectable and intranasal formulations, and zolmitriptan is available as an orally dissolving tablet.

Another option to consider is dihydroergotamine (DHE), which has long been used for migraine. The injectable formulation of DHE can be cumbersome because it requires the patients with a headache to open a vial, draw the medication into a filter needle, and inject themselves, said Dr. Nye. “The nasal sprays that are available right now aren’t as effective as we’d like them to be,” she added. But overall, DHE is effective. Associated adverse events include flushing, nausea, and diarrhea.

Lasmiditan received approval from the Food and Drug Administration for the acute treatment of migraine in October 2019. Compared with placebo, the drug increases the likelihood of pain freedom and freedom from the most bothersome symptom at 2 hours. Driving tests indicated that patients were impaired for about 8 hours after treatment, and lasmiditan is a Schedule V drug. It is available in doses of 50 mg/day, 100 mg/day, and 200 mg/day.

The class of drugs known as the “gepants” provides further options. The most recently approved therapy in this class, which targets calcitonin gene–related peptide, is ubrogepant. Because the drug is metabolized through the CYP3A4 system, they are not appropriate for patients who use strong CYP3A4 inhibitors. The most common side effects are nausea, hypersensitivity reaction, and somnolence.

Neuromodulation can provide effective treatment without provoking side effects, said Dr. Nye. Options include transcutaneous supraorbital stimulation, single-pulse transcutaneous magnetic stimulation, noninvasive vagal nerve stimulation, and remote nonpainful stimulation.

If a patient presents during an acute attack, neurologists could consider using a nerve block. The latter may administer occipital nerve blocks, trigger point injections, auriculotemporal nerve blocks, and supraorbital and supratrochlear nerve blocks. This treatment can bring immediate relief, which is gratifying for patients and neurologists. But no consensus about which medications to use or how to administer them has been established. Neurologists most often use a combination of bupivacaine and lidocaine. Another possibility is a sphenopalatine ganglion nerve block, which requires treatment to be inserted through the nose. This treatment can be delivered in the office using the Sphenocath device or the Allevio device. Another device, the Tx360, is intended to enable patient self-administration.
 

Addressing treatment failure

If a patient returns and reports that the current treatment is ineffective, the neurologist must reevaluate the therapy. A helpful way to conduct this reassessment is to administer the Migraine Treatment Optimization Questionnaire (MTOQ), which was developed by Lipton et al., to the patient. Neurologists ask whether the patient can function normally 2 hours after treatment or whether the medication is, for example, causing a side effect that makes this outcome less likely. Other questions for the patient are whether the headache pain disappears within 2 hours and whether the medication provides consistent relief. Finally, the neurologist can ask whether the patient is comfortable taking the medication. A score lower than 2 on the MTOQ indicates that the acute treatment should be changed, said Dr. Nye.

Gastroparesis is common during migraine attacks. It is inadvisable to give an oral medication to a patient who vomits within 20 minutes of attack onset, said Dr. Nye. “It’s a little less intuitive for those people who are nauseous immediately to think that that oral tablet is probably going to sit in their stomach and not get absorbed in the intestines as intended.” Nasal sprays, injectable medicines, and oral dissolving tablets are appropriate options for patients with gastroparesis.
 

Treating migraine during pregnancy

Special consideration must be given to treatment when the patient is pregnant. Decreased headache frequency is common in pregnancy, but not universal. Occipital nerve blocks are a good option for prevention and acute management in pregnant patients. They may be administered every 2 weeks. Sphenopalatine ganglion nerve block is another option, and it can be administered several times per week. Data “suggest that stacking the injections 2 or 3 days per week for up to 6 weeks can eliminate headaches for up to 6 months,” said Dr. Nye.

Tylenol is appropriate for acute headache in pregnant patients, “but we do warn about medication overuse headache and limiting its use.” Ondansetron and promethazine are acceptable treatments for nausea. Although ondansetron has less central activity than promethazine, and thus does not reduce the headache, it lessens nausea, said Dr. Nye.

Triptan exposure during the first trimester is not significantly associated with major congenital malformations, which is reassuring, given that many patients take triptans before they realize that they are pregnant. During the second and third trimesters, triptan exposure is significantly associated with atonic uterus and increased blood loss during labor. In a 16-year registry, sumatriptan, naratriptan, and treximet were not associated with teratogenicity.

Nonpharmacological treatments, too, may help pregnant patients. Lifestyle management, including a regular sleep schedule, exercise routine, and diet, can be beneficial. Massage therapy may reduce stress, and cognitive-behavioral therapy and biofeedback are additional options. Behavioral therapy, however, should be initiated before the patient plans the pregnancy, said Dr. Nye. These therapies require training that a patient having an exacerbation of migraine is less likely to have the motivation to begin.

Many medications are transferred to infants through breast milk. The American Pediatric Association considers a relative infant dosing of less than 10% to be safe. A clinician or patient can look up a medication on websites such as LactMed to understand the relative infant dose and possible effects. Another helpful reference is Medications and Mothers’ Milk, said Dr. Nye. Acetaminophen, steroids, ibuprofen, riboflavin, indomethacin, ketorolac, and naproxen are generally safe during lactation. “Eletriptan is the triptan that’s least likely to be in the breast milk,” said Dr. Nye. Aspirin, atenolol, ergotamine, and lithium, however, should be given with caution. The safety of amitriptyline, nortriptyline, and SSRIs during lactation is unknown.

Dr. Nye is on advisory boards for Alder, Allergan, Biohaven, electroCore, Pernix, and Xoc.

Sphenopalatine ganglion nerve block is another option, and it can be administered several times per week. Data “suggest that stacking the injections 2 or 3 days per week for up to 6 weeks can eliminate headaches for up to 6 months,” said Dr. Nye.

Tylenol is appropriate for acute headache in pregnant patients, “but we do warn about medication overuse headache and limiting its use.” Ondansetron and promethazine are acceptable treatments for nausea. Although ondansetron has less central activity than promethazine, and thus does not reduce the headache, it lessens nausea, said Dr. Nye.

Triptan exposure during the first trimester is not significantly associated with major congenital malformations, which is reassuring, given that many patients take triptans before they realize that they are pregnant. During the second and third trimesters, triptan exposure is significantly associated with atonic uterus and increased blood loss during labor. In a 16-year registry, sumatriptan, naratriptan, and treximet were not associated with teratogenicity.

Nonpharmacological treatments, too, may help pregnant patients. Lifestyle management, including a regular sleep schedule, exercise routine, and diet, can be beneficial. Massage therapy may reduce stress, and cognitive-behavioral therapy and biofeedback are additional options. Behavioral therapy, however, should be initiated before the patient plans the pregnancy, said Dr. Nye. These therapies require training that a patient having an exacerbation of migraine is less likely to have the motivation to begin.

Many medications are transferred to infants through breast milk. The American Pediatric Association considers a relative infant dosing of less than 10% to be safe. A clinician or patient can look up a medication on websites such as LactMed to understand the relative infant dose and possible effects. Another helpful reference is Medications and Mothers’ Milk, said Dr. Nye. Acetaminophen, steroids, ibuprofen, riboflavin, indomethacin, ketorolac, and naproxen are generally safe during lactation. “Eletriptan is the triptan that’s least likely to be in the breast milk,” said Dr. Nye. Aspirin, atenolol, ergotamine, and lithium, however, should be given with caution. The safety of amitriptyline, nortriptyline, and SSRIs during lactation is unknown.

Dr. Nye is on advisory boards for Alder, Allergan, Biohaven, electroCore, Pernix, and Xoc.

The Consortium of Multiple Sclerosis Centers (CMSC) and the National Multiple Sclerosis Society (NMSS) have created a database to collect information on COVID-19 infections and outcomes in North American patients with multiple sclerosis (MS) and related diseases. The COViMS (COVID-19 Infections in Multiple Sclerosis and Related Diseases) database is gathering information from patients throughout the United States and will soon gain access to Canadian data. Data from patients with CNS demyelinating diseases such as neuromyelitis optica and myelin oligodendrocyte glycoprotein antibody diseases also will be included in COViMS. Amber Salter, PhD, MPH, the director of the North American Research Committee on MS (NARCOMS) is supervising the data collection and analyses.

“COViMS will provide valuable insight on how COVID-19 affects people with MS, including if certain disease-modifying treatments incur special risks,” said June Halper, CEO of CMSC, in a press release.

The project began when CMSC and NMSS established independent registries of epidemiologic data related to MS and COVID-19. The two groups soon began communicating and included other researchers, who also were considering establishing registries, in their discussions. In addition, representatives of the Cleveland Clinic verbally agreed to share data that they have been collecting with the COViMS registry. “The fast-moving, almost parallel, efforts led to this collaboration,” said Gary Cutter, PhD, professor of biostatistics at the University of Alabama at Birmingham. “This in itself is noteworthy because all of this took place within an incredibly short time from inception to the initiation of data collection.”

The effects of SARS-CoV-2 infection on the health of patients with MS is little understood. In North America, no reporting system had been organized to gather information on these patients and track outcomes. Such a system could influence the treatment of people with MS who become infected with the novel coronavirus or other similar future viruses. The COViMS registry is intended to define the impact of COVID-19 on patients with MS and ascertain how factors such as age, comorbidities, and MS treatments affect outcomes of COVID-19. “The estimated median age of MS patients in the U.S. is about 52 years, thus putting many at increased risk just due to age,” said Dr. Cutter.

“People with MS and their health care providers need evidence-based guidance to provide optimal MS care during the COVID-19 pandemic, and the COViMS database will help answer the many pressing questions,” said Bruce Bebo, executive vice president of research for the NMSS, in a press release.

The two organizations encourage neurologists and other health care providers who treat patients with MS and documented COVID-19 infection to complete a Case Report Form on the COViMS website, which includes answers to frequently asked questions, a sample CRF, and other resources. The website will provide real-time data once registry participation is underway.

The Food and Drug Administration has approved selumetinib (Koselugo) for the treatment of pediatric patients aged 2 years and older with type 1 neurofibromatosis (NF1) with symptomatic, inoperable plexiform neurofibromas.

FDA approval was based on results from the phase 2 SPRINT Stratum 1 trial, in which 50 patients with NF1 received selumetinib as twice-daily oral monotherapy. Of this group, 33 (66%) patients had a partial response of at least a 20% reduction in tumor volume. There were no complete responses, according to a press release.

The most common adverse events were vomiting, rash, abdominal pain, diarrhea, nausea, dry skin, fatigue, musculoskeletal pain, pyrexia, rash acneiform, stomatitis, headache, paronychia, and pruritus. Dose interruptions, dose reductions, and permanent drug discontinuation occurred in 80%, 24%, and 12% of patients, respectively.

Serious adverse reactions included cardiomyopathy, ocular toxicity, gastrointestinal toxicity, increased creatinine phosphokinase, and increased vitamin E levels and risk of bleeding, according to the press release.

“Previously, there were no medicines approved for this disease. This approval has the potential to change how symptomatic, inoperable NF1 plexiform neurofibromas are treated and provides new hope to these patients,” Roy Baynes, MD, PhD, senior vice president, head of global clinical development, and chief medical officer of Merck Research Laboratories, said in the press release.

Patients with migraine who are unable to continue preventive procedures such as onabotulinumtoxinA injections during the COVID-19 pandemic may be at risk of worsening migraine, according to an article published March 30 in Headache. To address this scenario, clinicians may need to prescribe additional acute or preventive medications. Insurance providers should adjust their policies to facilitate transitions to other preventive therapies, including monoclonal antibodies against calcitonin gene-related peptide (CGRP) or the CGRP receptor, the authors said.

“This is a particularly vulnerable time for individuals with migraine and other disabling headache disorders, with many physical and mental stressors, increased anxiety, and changes in daily routine which may serve as triggering factors for worsening headache,” said lead author Christina L. Szperka, MD, director of the pediatric headache program at Children’s Hospital of Philadelphia, and colleagues.
 

Acute treatment

The authors described potential treatment regimens based on their experience as headache specialists and the experiences of their colleagues. For acute therapy options, NSAIDs, triptans, and neuroleptics may be used in combination when needed. Medications within the same drug category should not be combined, however, and triptans, dihydroergotamine, and lasmiditan should not be coadministered within 24 hours. Since the 2015 American Headache Society guideline for the acute treatment of migraine, the Food and Drug Administration has approved additional acute migraine medications, including ubrogepant, rimegepant, and lasmiditan, the authors said. The agency also cleared several neuromodulation devices for the acute treatment of migraine.

Although few drugs have been studied as treatments for unusually prolonged severe headaches, headache doctors often recommend NSAIDs before patients seek care at an emergency department or infusion center, the authors said. NSAID options include indomethacin, ketorolac, naproxen, nabumetone, diclofenac, and mefenamic acid. Neuroleptics also may be used. “Long-acting triptan medications can be used as bridge therapies, as is often done in the treatment of menstrually related migraine or in the treatment of medication overuse headache,” they said. “We propose a similar strategy can be trialed as a therapeutic option for refractory or persistent migraine.”

The authors also described the use of antiepileptics and corticosteroids, as well as drugs that may treat specific symptoms, such as difficulty sleeping (hydroxyzine or amitriptyline), neck or muscle pain (tizanidine), and aura with migraine (magnesium). Clinicians should avoid the use of opioids and butalbital, they said.
 

Preventive treatment

“While the injection of onabotulinumtoxinA is an effective treatment for chronic migraine, the procedure can put the patient and the provider at higher risk of COVID-19 given the close contact encounter,” wrote Dr. Szperka and colleagues. “We believe that other migraine preventive treatments should be utilized first when possible.” Since the publication of a guideline on preventive migraine therapies in 2012, the FDA has approved additional preventive therapies, including the anti-CGRP monoclonal antibodies erenumab‐aooe, galcanezumab‐gnlm, fremanezumab‐vfrm, and eptinezumab‐jjmr. “The first three are intended for self‐injection at home, with detailed instructions available for each product on its website,” they said.

Among angiotensin‐converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs), candesartan has evidence of efficacy and tolerability in migraine prevention. Lisinopril has been considered possibly effective. “There has been recent concern in the media about the possibility of these medications interfering with the body’s response to COVID‐19,” the authors said, although this theoretical concern was not based on experimental or clinical data. “For patients in need of a new preventive therapy, the potential for benefit with an ACE/ARB must be weighed against the theoretical increased risk of infection.”

In addition, studies indicate that melatonin may prevent migraine with few side effects and that zonisamide may be effective in patients who have an inadequate response to or experience side effects with topiramate.
 

Policy changes and telehealth options

Effectively treating patients with migraine during the pandemic requires policy changes, according to the authors. “Migraine preventive prior authorization restrictions need to be lifted for evidence‐based, FDA‐approved therapies; patients need to be able to access these medications quickly and easily. Patients should not be required to fail older medications,” they said. “Similarly, in order to permit the transition of patients from onabotulinumtoxinA to anti‐CGRP [monoclonal antibodies], insurers should remove the prohibition against simultaneous coverage of these drug classes.” Insurers also should loosen restrictions on the off-label use of acute and preventive medication for adolescents, Dr. Szperka and coauthors suggest.

“In the era of COVID‐19, telehealth has become an essential modality for most headache specialists, given the need for providers to take significant precautions for both their patients and themselves, limiting touch or close contact,” they said. Patients with headache may warrant additional screening for COVID-19 as well. “As headache has been reported as an early symptom of COVID‐19, patients with worsening or new onset severe headache should be reviewed for exposure risk and any other symptoms which may be consistent with COVID‐19 infection,” the authors said.

There was no direct funding for the report. Dr. Szperka and a coauthor receive salary support from the National Institutes of Health. Dr. Szperka also has received grant support from Pfizer, and her institution has received compensation for her consulting work for Allergan. Several coauthors disclosed consulting and serving on speakers’ bureaus for and receiving research support from various pharmaceutical companies.

People living with dementia and their caregivers urgently need mental health and psychosocial support during the coronavirus pandemic, according to a letter published online ahead of print March 30 in Lancet. Consistent with recommendations from Alzheimer’s Disease International and other dementia experts, teams that include mental health professionals, social workers, nursing home administrators, and volunteers should collaborate to provide mental health care for people with dementia. Experts in dementia should lead each team and support team members from other disciplines, wrote Huali Wang, MD, chair of clinical research at Peking University Institute of Mental Health in Beijing, and colleagues.

Interventions could be administered through telehealth, said the authors. Teams led by mental health professionals could use electronic media to provide self-help guidance for reducing stress, such as relaxation or meditation exercise. These teams also could use telephone hotlines to support behavioral management, and psychological counselors could provide online consultations for caregivers in nursing homes or in the community. “We encourage people who have a parent with dementia to have more frequent contact or spend more time with their parent, or to take on some of the caregiving duties so as to give the carer some respite time,” wrote Dr. Wang and colleagues.

Many local authorities are banning visits to nursing home residents to reduce the latter’s risk of COVID-19 infection. As a consequence, these elderly people are becoming more isolated, and anxiety is increasing among nursing home staffs.

In China, five organizations, including the Chinese Society of Geriatric Psychiatry and Alzheimer’s Disease Chinese, responded to the COVID-19 outbreak by publishing recommendations for providing mental health and psychosocial support. Groups of providers from various disciplines offered free counseling services for people with dementia and their caregivers. “These approaches minimized the complex impact of both COVID-19 outbreak and dementia,” wrote the authors.

“China has contained the epidemic, and business is starting to return to normal,” they continued. “We believe that learning lessons from China would empower the world to tackle the COVID-19 pandemic, with little risk of compromising the quality of life of people living with dementia and their carers.”

Dr. Wang has received lecture fees from Eisai China and Lundbeck China. She owns the copyright for the neuropsychiatric symptoms individualized management system. Her coauthors reported serving as advisory board members and receiving fees from companies such as Biogen, Novartis, and Genentech.

These teams also could use telephone hotlines to support behavioral management, and psychological counselors could provide online consultations for caregivers in nursing homes or in the community. “We encourage people who have a parent with dementia to have more frequent contact or spend more time with their parent, or to take on some of the caregiving duties so as to give the carer some respite time,” wrote Dr. Wang and colleagues.

Many local authorities are banning visits to nursing home residents to reduce the latter’s risk of COVID-19 infection. As a consequence, these elderly people are becoming more isolated, and anxiety is increasing among nursing home staffs.

In China, five organizations, including the Chinese Society of Geriatric Psychiatry and Alzheimer’s Disease Chinese, responded to the COVID-19 outbreak by publishing recommendations for providing mental health and psychosocial support. Groups of providers from various disciplines offered free counseling services for people with dementia and their caregivers. “These approaches minimized the complex impact of both COVID-19 outbreak and dementia,” wrote the authors.

“China has contained the epidemic, and business is starting to return to normal,” they continued. “We believe that learning lessons from China would empower the world to tackle the COVID-19 pandemic, with little risk of compromising the quality of life of people living with dementia and their carers.”

People living with dementia and their caregivers urgently need mental health and psychosocial support during the coronavirus pandemic, according to a letter published online ahead of print March 30 in Lancet. Consistent with recommendations from Alzheimer’s Disease International and other dementia experts, teams that include mental health professionals, social workers, nursing home administrators, and volunteers should collaborate to provide mental health care for people with dementia. Experts in dementia should lead each team and support team members from other disciplines, wrote Huali Wang, MD, chair of clinical research at Peking University Institute of Mental Health in Beijing, and colleagues.
