Brain differences suggest therapeutic targets in Takotsubo
A new study has identified differences in the brain present in patients with the cardiac disorder Takotsubo syndrome versus control scans, which may lead to new therapeutic targets.
Takotsubo syndrome is an acute heart failure cardiomyopathy mimicking an acute myocardial infarction in its presentation, but on investigation, no obstructive coronary disease is present. The syndrome, which mainly affects women, typically occurs in the aftermath of intense emotional or physical stress and has become known as “broken heart syndrome.”
The mechanism by which emotional processing in the context of stress leads to significant cardiac injury and acute left ventricular dysfunction is not understood. So, the current study examined both structural and functional effects in the brain in patients with Takotsubo syndrome to shed more light on the issue.
“The abnormalities in the thalamus-amygdala-insula and basal ganglia support the concept of involvement of higher-level function centers in Takotsubo syndrome, and interventions aimed at modulating these may be of benefit,” the authors conclude.
The study was published online in JACC: Heart Failure.
Lead author Hilal Khan, MB BCh, BAO, from the University of Aberdeen (Scotland), explained to this news organization that patients with Takotsubo syndrome have a substantial drop in heart function and show an apical ballooning of the heart.
It is a relatively newly defined condition and was first described in 1990 in Japan, and so named because the heart was thought to resemble the Takotsubo pot used by Japanese fishermen to trap octopus.
Although uncommon, the condition is not rare. Dr. Khan estimates that about 1 in 20 women with suspected MI turn out to have Takotsubo syndrome, with cases increasing in times of global stress such as in the recent pandemic.
While patients tend to recover in a few weeks and the pumping function of the heart usually returns to normal, there are some long-term cardiac complications including a reduction in global longitudinal strain, and patients have similar long-term outcomes as those with MI.
“It is believed that these cardiac changes may be triggered by changes in the brain caused by emotional stress, so we wanted to look at this more closely,” Dr. Khan said.
There have been a couple of studies published previously looking at brain changes in Takotsubo syndrome, but they haven’t reported patients in the acute stage of the condition and they haven’t compared the patients to controls, he noted.
For the current study, the researchers looked at brain scans for 25 acute Takotsubo patients and in 25 controls matched for age, gender, comorbidities, and medications. All the patients and controls were examined using the same MRI scanner in the same hospital.
“This is the largest structural and functional brain study of acute Takotsubo syndrome patients compared with matched control subjects,” Dr. Khan said.
The researchers looked at many different factors including brain volume in different regions, cortical thickness, small-vessel disease, and functional and structural connectivity to try and obtain a complete holistic view of the brain.
Key findings were that patients with Takotsubo syndrome had smaller brain volumes, compared with matched controls, driven by a reduction in brain surface area. In contrast, the insula and thalamus regions were larger.
“A reduction in brain volume could be caused by inflammation; this is often seen in depression,” Dr. Khan commented.
The researchers also found that certain areas of the brain had a reduction in functional connectivity, particularly the thalamus – the central autonomic area of the brain, which regulates the autonomic nervous system – and also the insula region, which is also involved in the autonomic regulation of the heart.
They suggest that there may be a loss of parasympathetic inhibition in Takotsubo syndrome, which would fit the theory that Takotsubo brings with it a surge of catecholamines, which could injure the heart.
Reduced functional connectivity was also seen in parts of the basal ganglia, abnormalities of which have been associated with an increased risk of both arrhythmias, and in the amygdala, similar to patients with a tendency to catastrophize events.
The other observation was that there appeared to be an increase in structural connectivity in certain areas of the brain.
“Structural pathways seem to be increased but functional connectivity was reduced, so while physical pathways are enhanced, they don’t seem to be doing anything,” Dr. Khan said. “We don’t know why this occurs, or if this has happened over time and made the brain and heart more vulnerable in some way.”
One possibility is that ,under a significant emotional stress, the brain may divert function from some areas to others to be able to cope, and that this results in reduced functioning in areas of the brain responsible for regulating the heart, Dr. Khan suggested.
“We believe this study confirms that the brain is involved in Takotsubo syndrome, and we have identified markers in the brain that may be contributing to the condition,” he said.
The researchers are planning to further study these markers and whether it might be possible to modulate these changes with various interventions such as exercise or mindfulness.
“We believe there is some interface between the brain changes and the impact on the heart. We don’t think it is just the release of catecholamines that causes damage to the heart. We think there is something else happening as well,” Dr. Khan commented.
It is also possible that the hearts of patients with Takotsubo syndrome are predisposed in some way and more vulnerable to this condition occurring.
“It will be important to obtain a greater understanding of the triggers and identify people who may be vulnerable,” Dr. Khan noted. “Around 10% of individuals who experience Takotsubo syndrome will have a recurrence, so we need to try and develop preventative strategies to reduce this.”
He suggested that possible preventive or therapeutic approaches may involve interventions such as exercise or mindfulness.

FROM JACC: HEART FAILURE
The loss of letters
My desk looks nothing like my grandfather’s. It stands about mid-abdomen high and has a small surface, perhaps just enough for the monitor and a mug. Yes, I can move it up and down (thank you 21st century), but it has no drawers. It is lean and immaculate, but it has no soul.
My grandfather sat at a large oak desk with three drawers on each side. Each was so heavy you had to be at least 6 years old to pull one open for exploring the contents inside. The desk surface was vast and although immobile, it had a greenish leather blotter for writing. Alongside his pile of correspondences was a treasure for those of us tall enough to get it: A heavy brass letter opener. It came, I believe, with a secretary who would open his letters and stack them neatly before placing this sometimes-pirate’s-sword far enough away from the edge for us to not reach it.
Upon my skinny, adaptable desk the other day sat a white envelope that was hand addressed to me. It was postmarked more than 2 weeks before as it had been waylaid in Endocrinology before being couriered to the rightful recipient. It had not been opened. Nor did I have any way to do so gracefully. I tore it apart with a fat finger while clicking through path reports that just arrived in my inbox.
Dear Dr. Benabio,
Pat
. She carefully looped her “y’s” and crossed her “t’s.” Not one cross out. She thought about each sentence before transcribing it. The paper once sat on her desk, touched her fingers and the envelope sealed with her saliva. It was not filled with trifling requests or complaints. It was not efficient, but it was more than just communication. She took the time to choose the words to capture her emotion and express her gratitude. It was respectful, dignified, decidedly nondigital. For a brief moment I thought I might write back, but quickly realized that was impractical. I knew I wouldn’t make the time to do so. I wish I had.
Having no drawers to save it, I held it up with just a corner of the page resting on my desk and scribbled in black ink “Reviewed. Please scan to media file. 12/8/22. JAB”

It’s all about the brains: Guilt placebos, transplants, and negative feelings
Guilt reduction, now in deceptive and open-secret forms
Guilt plagues a lot of us, sometimes regularly. Maybe you felt bad about eating the leftovers that your partner was looking forward to eating at the end of the day. Or for not saving a seat for your friend who was running late to the movies. Maybe even hiding a secret that you know would hurt a person’s feelings. We’ve all felt it, and it doesn’t feel good.
But what if there was a pill that would make those feelings seem to hurt less? There’s already a pill for almost everything, right?
Well, researchers from the University of Basel are on the case and have conducted a study suggesting that a placebo might work. They asked participants to write down a time they felt super guilty about something, just to stir up those feelings again, then they were divided into three groups. One group was told they would receive real medication that was actually a placebo, one was told they would get a placebo, and one got nothing. The subjects’ guilty feelings were reduced in both the medication-that-was-really-a-placebo group and placebo-that-was-a-placebo group.
“Our study therefore supports the intriguing finding that placebos work even when they are administered openly, and that explanation of the treatment is key to its effectiveness,” lead author Dilan Sezer said in a written statement.
More research is needed, but the human mind is a very interesting place. It seems like we can convince ourselves of just about anything. Especially to feel less guilty.
It’s a mad, mad, mad, mad scientist’s world
Mad scientists. Life’s just more interesting with a few of them running around, but they’re mostly relegated to works of fiction. Real life is boring; we don’t actually have neurosurgeons going around claiming human brain transplant is technically feasible.
Best of all, this isn’t even Dr. Sergio Canavero’s first rodeo with mad science: In 2015 he claimed human head transplants were technically feasible, and in the past few years has claimed to have rehearsed head transplants on cadavers and successfully repaired spinal cord injuries in animals. Lots of claims in there, but precious little evidence. And contrary to what everyone at the head enhancement clinic says, people will notice if you start going around with a new head.
But let’s get back to brains. Ignoring the fact that brain transplant sounds like a zombie with a PhD nibbling on your skull, the article does appear in a peer-reviewed journal. So surely there’s some level of legitimacy. After all, it’s not like Dr. Canavero is an editor for this journal. [Editor’s note: By that we mean he is an editor for the journal.]
Man, he’s taking all the fun out of this.
Anyway, now that we’ve prefaced this with the mother of all caveats, what exactly is Dr. Canavero proposing with his brain transplant? It’s pretty simple: Just have a robot scoop out the first brain and place it into a fresh body, either a donated but moribund younger body or a cloned body. Reconnect all the nerves and vasculature and you’re good to go. Enjoy your wine and laugh in the face of death.
Naturally, such a … bold proposal is lacking in the details, but who cares about details, anyway? This is mad science, not respectable science. Professionals have standards. And if we hear that a human brain transplant was successfully completed on a non–dark and stormy night and the doctor didn’t cackle madly “It’s alive! It’s alive!” then honestly, what even was the point?
Ambivalence rules!
As the office’s unofficial Sith lord/Star Wars nerd, LOTME takes notice when science extols the benefits of unhappiness: “It’s good to be grumpy: Bad moods make us more detail-oriented, study shows.”
The investigators manipulated the emotions of participants by having them watch a clip from “Sophie’s Choice” or one from “Friends.” Then the subjects listened to short, emotionally neutral stories, some of which contained inconsistencies, with the text displayed on a computer screen. Sorry to say, gang at Central Perk, but round one went to the sad movie.
“When people are in a negative mood, they are more careful and analytical. They scrutinize what’s actually stated in a text, and they don’t just fall back on their default world knowledge,” lead author Vicky Lai, PhD, of the University of Arizona said in a statement from the school.
Negative mood. Careful and analytical. Grumpy is good.
You’ve fallen into Darth Science’s little trap, and we have you now.
A study conducted at the University of Geneva offers a slightly different conclusion. And by slightly different, we mean completely different. People over age 65 who watched a series of short TV clips depicting people in a state of emotional suffering experienced excessive modification of their neuronal connections, compared with those who watched emotionally neutral videos.
The brains of these subjects remained “frozen in a negative state by relating the suffering of others to their own emotional memories,” lead author Sebastian Baez Lugo said in a written release from the university.
Emotional suffering. Frozen brains. Grumpy is … not good?
So there you have it. Darth Science’s lesson for the day: A negative mood makes you careful and analytical, but negative thoughts are bad for your brain.

People over age 65 who watched a series of short TV clips depicting people in a state of emotional suffering experienced excessive modification of their neuronal connections, compared with those who watched emotionally neutral videos.
The brains of these subjects remained “frozen in a negative state by relating the suffering of others to their own emotional memories,” lead author Sebastian Baez Lugo said in a written release from the university.
Emotional suffering. Frozen brains. Grumpy is … not good?
So there you have it. Darth Science’s lesson for the day: A negative mood makes you careful and analytical, but negative thoughts are bad for your brain.
Guilt reduction, now in deceptive and open-secret forms
Guilt plagues a lot of us, sometimes regularly. Maybe you felt bad about eating the leftovers that your partner was looking forward to eating at the end of the day. Or for not saving a seat for your friend who was running late to the movies. Maybe even hiding a secret that you know would hurt a person’s feelings. We’ve all felt it, and it doesn’t feel good.
But what if there was a pill that would make those feelings seem to hurt less? There’s already a pill for almost everything, right?
Well, researchers from the University of Basel are on the case and have conducted a study suggesting that a placebo might work. They asked participants to write down a time they felt super guilty about something, just to stir up those feelings again, then they were divided into three groups. One group was told they would receive real medication that was actually a placebo, one was told they would get a placebo, and one got nothing. The subjects’ guilty feelings were reduced in both the medication-that-was-really-a-placebo group and placebo-that-was-a-placebo group.
“Our study therefore supports the intriguing finding that placebos work even when they are administered openly, and that explanation of the treatment is key to its effectiveness,” lead author Dilan Sezer said in a written statement.
More research is needed, but the human mind is a very interesting place. It seems like we can convince ourselves of just about anything. Especially to feel less guilty.
It’s a mad, mad, mad, mad scientist’s world
Mad scientists. Life’s just more interesting with a few of them running around, but they’re mostly relegated to works of fiction. Real life is boring; we don’t actually have neurosurgeons going around claiming human brain transplant is technically feasible.
Best of all, this isn’t even Dr. Sergio Canavero’s first rodeo with mad science: In 2015 he claimed human head transplants were technically feasible, and in the past few years has claimed to have rehearsed head transplants on cadavers and successfully repaired spinal cord injuries in animals. Lots of claims in there, but precious little evidence. And contrary to what everyone at the head enhancement clinic says, people will notice if you start going around with a new head.
But let’s get back to brains. Ignoring the fact that brain transplant sounds like a zombie with a PhD nibbling on your skull, the article does appear in a peer-reviewed journal. So surely there’s some level of legitimacy. After all, it’s not like Dr. Canavero is an editor for this journal. [Editor’s note: By that we mean he is an editor for the journal.]
Man, he’s taking all the fun out of this.
Anyway, now that we’ve prefaced this with the mother of all caveats, what exactly is Dr. Canavero proposing with his brain transplant? It’s pretty simple: Just have a robot scoop out the first brain and place it into a fresh body, either a donated but moribund younger body or a cloned body. Reconnect all the nerves and vasculature and you’re good to go. Enjoy your wine and laugh in the face of death.
Naturally, such a … bold proposal is lacking in the details, but who cares about details, anyway? This is mad science, not respectable science. Professionals have standards. And if we hear that a human brain transplant was successfully completed on a non–dark and stormy night and the doctor didn’t cackle madly “It’s alive! It’s alive!” then honestly, what even was the point?
Ambivalence rules!
As the office’s unofficial Sith lord/Star Wars nerd, LOTME takes notice when science extols the benefits of unhappiness: “It’s good to be grumpy: Bad moods make us more detail-oriented, study shows.”
The investigators manipulated the emotions of participants by having them watch a clip from “Sophie’s Choice” or one from “Friends.” Then the subjects listened to short, emotionally neutral stories, some of which contained inconsistencies, with the text displayed on a computer screen. Sorry to say, gang at Central Perk, but round one went to the sad movie.
“When people are in a negative mood, they are more careful and analytical. They scrutinize what’s actually stated in a text, and they don’t just fall back on their default world knowledge,” lead author Vicky Lai, PhD, of the University of Arizona said in a statement from the school.
Negative mood. Careful and analytical. Grumpy is good.

How to talk with patients in ways that help them feel heard and understood
How do we become those professionals and make sure that we are doing a good job connecting and communicating with our patients?
Here are a few suggestions on how to do this.
Practice intent listening
When a patient shares their symptoms with you, show genuine curiosity and concern. Ask clarifying questions. Ask how the symptom or problem is affecting their day-to-day life. Avoid quick, rapid-fire questions back at the patient. Do not accept a patient self-diagnosis.
When a patient with a first-time headache says they are having a migraine headache, for example, ask many clarifying questions to make sure you can make a diagnosis of headache type, then use all the information you have gathered to educate the patient on what you believe they have.
It is easy to jump to treatment, but we always want to make sure we have the diagnosis correct first. By intently listening, it also makes it much easier to tell a patient you do not know what is causing their symptoms, but that you and the patient will be vigilant for any future clues that may lead to a diagnosis.
Use terminology that patients understand
Rachael Gotlieb, MD, and colleagues published an excellent study with eye-opening results on common phrases we use as health care providers and how often patients do not understand them.
Only 9% of patients understood what was meant when they were asked if they have been febrile. Only 2% understood what was meant by “I am concerned the patient has an occult infection.” Only 21% understood that “your xray findings were quite impressive” was bad news.
It is easy to avoid these medical language traps, we just have to check our doctor speak. Ask, “Do you have a fever?” Say, “I am concerned you may have an infection that is hard to find.”
Several other terms we use all the time in explaining things to patients that I have found most patients do not understand are the terms bilateral, systemic, and significant. Think carefully as you explain things to patients and check back to have them repeat to you what they think you said.
Be comfortable saying you don’t know
Many symptoms in medicine end up not being diagnosable. When a patient shares symptoms that do not fit a pattern of a disease, it is important to share with them why you think it is okay to wait and watch, even if you do not have a diagnosis.
Patients find it comforting that you are so honest with them. Doing this also has the benefit of gaining patients’ trust when you are sure about something, because it tells them you don’t have an answer for everything.
Ask your patients what they think is causing their symptoms
This way, you know what their big fear is. You can address what they are worried about, even if it isn’t something you are considering.
Patients are often fearful of a disease a close friend or relative has, so when they get new symptoms, they fear diseases that we might not think of. By knowing what they are fearful of, you can reassure when appropriate.

Renowned stroke expert Ralph L. Sacco, MD, dies
Ralph L. Sacco, MD, the first neurologist to serve as president of the American Heart Association and the only physician to serve as president of both the AHA and the American Academy of Neurology, died Jan. 17 at the age of 65.
He died of a brain tumor at his home in Amagansett, N.Y., according to an obituary published in Neurology, Circulation, and Stroke.
“Ralph was one of a kind,” Nancy Brown, chief executive officer for the AHA and American Stroke Association, said in a statement. “His leadership was unparalleled, and his warm, generous heart and care transcended his research and clinic to every person fortunate to meet him and likely become a friend,” Ms. Brown said.
In a tweet, Natalia S. Rost, MD, professor of neurology at Harvard Medical School, Boston, called him, “a dear friend, an inspiring colleague, a generous mentor, an astute scientist, a consummate advocate for brain health worldwide.”
Dedicated to improving stroke care
Dr. Sacco was chair of the University of Miami Miller School of Medicine in the department of neurology; the Olemberg Family Chair in Neurological Disorders; professor of neurology, public health sciences, human genetics, and neurosurgery; executive director of the Evelyn F. McKnight Brain Institute; director and multi-principal investigator of the Miami Clinical and Translational Science Institute; and senior associate dean for clinical and translational science.
Dr. Sacco was a population-based researcher in the field of cerebrovascular diseases.
As founder of the Northern Manhattan Study, he paved the way for examining the differences in stroke risk related to race, ethnicity, sex, and neighborhood, and realizing the impact of modifiable lifestyle behaviors, such as alcohol consumption and physical activity, on stroke risk.
Dr. Sacco’s work led to more targeted stroke prevention programs and his “drive and dedication fueled changes that improved stroke research and fostered the development of targeted stroke care delivery, ultimately improving stroke recovery and post-stroke quality of life for many,” the AHA statement said.
Dr. Sacco was also founder and executive director of the Florida Stroke Registry, which consists of 167 Florida stroke centers. He was a member of the National Academy of Medicine.
In an obituary written by Orly Avitzur, MD, current president of the AAN, she notes that he “was the only physician to have become both the president of the AHA (2010-2011) and the AAN (2017-2019), positions that reflected the respect and admiration of professional colleagues earned over the years.”
During his tenure as AAN president, Dr. Sacco led an initiative to ensure that academic neurology, from department chairs to professors to students, knew about the abundance of academy resources available to them, the AAN noted in a statement.
Dr. Sacco was a “strong proponent of enlarging the neurology workforce through the academic pipeline and promoted the concept of the ‘newrologist’ to get people excited in careers in neurology, moving beyond just diagnosis and treatments to include interventions, preventative care, and the future of regenerative care,” the AAN said.
Dr. Sacco received numerous awards throughout his career, most recently the AHA 2022 Distinguished Scientist award. He also received the 2015 Gold Heart Award, the 2011 Distinguished National Leadership Award, and the 2006 William Feinberg Award.
In addition to his husband, Scott Dutcher, Dr. Sacco is survived by his father, Anthony P. Sacco, and his father’s wife, Rosemary; and his four siblings and their families, along with many nieces and nephews.

Adverse events reported in one-quarter of inpatient admissions
as indicated from data from 2,809 admissions at 11 hospitals.
The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.
“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.
In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.
Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.
A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.
A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.
The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.
Overcoming barriers to better safety
“The overall level of harm, with nearly 1 in 4 patients suffering an adverse event, was higher than I expected it might be,” Dr. Bates told this news organization. However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.
“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”
“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.
As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.
The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.
However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
Timely reassessment and opportunities to improve
In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.
“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.
“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.
“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.
The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

However, techniques for identifying adverse events have improved, and “it is easier to find them in electronic records than in paper records,” he noted.
“Hospitals have many issues they are currently dealing with since COVID, and one issue is simply prioritization,” Dr. Bates said. “But it is now possible to measure harm for all patients using electronic tools, and if hospitals know how much harm they are having in specific areas, they can make choices about which ones to focus on.”
“We now have effective prevention strategies for most of the main kinds of harm,” he said. Generally, rates of harm are high because these strategies are not being used effectively, he said. “In addition, there are new tools that can be used – for example, to identify patients who are decompensating earlier,” he noted.
As for additional research, some specific types of harm that have been resistant to interventions, such as pressure ulcers, deserve more attention, said Dr. Bates. “In addition, diagnostic errors appear to cause a great deal of harm, but we don’t yet have good strategies for preventing these,” he said.
The study findings were limited by several factors, including the use of data from hospitals that might not represent hospitals at large and by the inclusion mainly of patients with private insurance, the researchers write. Other limitations include the likelihood that some adverse events were missed and the level of agreement on adverse events between adjudicators was only fair.
However, the findings serve as a reminder to health care professionals of the need for continued attention to improving patient safety, and measuring adverse events remains a critical part of guiding these improvements, the researchers conclude.
Timely reassessment and opportunities to improve
In the decades since the publication of the report, “To Err Is Human,” by the National Academies in 2000, significant attention has been paid to improving patient safety during hospitalizations, and health care systems have increased in both system and disease complexity, Said Suman Pal, MBBS, a specialist in hospital medicine at the University of New Mexico, Albuquerque, said in an interview. “Therefore, this study is important in reassessing the safety of inpatient care at the current time,” he said.
“The findings of this study showing preventable adverse events in approximately 7% of all admissions; while concerning, is not surprising, as it is consistent with other studies over time, as the authors have also noted in their discussion,” said Dr. Pal. The current findings “underscore the importance of continuous quality improvement efforts to increase the safety of patient care for hospitalized patients,” he noted.
“The increasing complexity of medical care, fragmentation of health care, structural inequities of health systems, and more recent widespread public health challenges such as the COVID-19 pandemic have been, in my opinion, barriers to improving patient safety,” Dr. Pal said. “The use of innovation and an interdisciplinary approach to patient safety and quality improvement in hospital-based care, such as the use of machine learning to monitor trends and predict the individualized risk of harm, could be a potential way out” to help reduce barriers and improve safety, he said.
“Additional research is needed to understand the key drivers of preventable harm for hospitalized patients in the United States,” said Dr. Pal. “When planning for change, keen attention must be paid to understanding how these [drivers] may differ for patients who have been historically marginalized or are otherwise underserved so as to not exacerbate health care inequities,” he added.
The study was funded by the Controlled Risk Insurance Company and the Risk Management Foundation of the Harvard Medical Institutions. Dr. Bates owns stock options with AESOP, Clew, FeelBetter, Guided Clinical Solutions, MDClone, and ValeraHealth and has grants/contracts from IBM Watson and EarlySense. He has also served as a consultant for CDI Negev. Dr. Pal has disclosed no relevant financial relationships.

as indicated from data from 2,809 admissions at 11 hospitals.
The 1991 Harvard Medical Practice Study, which focused on medical injury and litigation, documented an adverse event rate of 3.7 events per 100 admissions; 28% of those events were attributed to negligence, write David W. Bates, MD, of Brigham and Women’s Hospital, Boston, and colleagues.
Although patient safety has changed significantly since 1991, documenting improvements has been challenging, the researchers say. Several reports have shown a decrease in health care–associated infections. However, other aspects of safety – notably, adverse drug events, defined as injuries resulting from drugs taken – are not easily measured and tracked, the researchers say.
“We have not had good estimates of how much harm is being caused by care in hospitals in an ongoing way that looked across all types of adverse events,” and the current review is therefore important, Dr. Bates said in an interview.
In a study recently published in the New England Journal of Medicine, the researchers analyzed a random sample of 2,809 hospital admissions from 11 hospitals in Massachusetts during the 2018 calendar year. The hospitals ranged in size from fewer than 100 beds to more than 700 beds; all patients were aged 18 years and older. A panel of nine nurses reviewed the admissions records to identify potential adverse events, and eight physicians reviewed the adverse event summaries and either agreed or disagreed with the adverse event type. The severity of each event was ranked using a general severity scale into categories of significant, serious, life-threatening, or fatal.
Overall, at least one adverse event was identified in 23.6% of the hospital admissions. A total of 978 adverse events were deemed to have occurred during the index admission, and 222 of these (22.7%) were deemed preventable. Among the preventable adverse events, 19.7% were classified as serious, 3.3% as life-threatening, and 0.5% as fatal.
A total of 523 admissions (18.6%) involved at least one significant adverse event, defined as an event that caused unnecessary harm but from which recovery was rapid. A total of 211 admissions involved a serious adverse event, defined as harm resulting in substantial intervention or prolonged recovery; 34 included at least one life-threatening event; and seven admissions involved a fatal adverse event.
A total of 191 admissions involved at least one adverse event deemed preventable. Of those, 29 involved at least one preventable adverse event that was serious, life-threatening, or fatal, the researchers write. Of the seven deaths in the study population, one was deemed preventable.
The most common adverse events were adverse drug events, which accounted for 39.0% of the adverse events; surgical or other procedural events accounted for 30.4%; patient care events (including falls and pressure ulcers) accounted for 15.0%; and health care–associated infections accounted for 11.9%.

HRT may prevent Alzheimer’s in high-risk women
new research suggests.
Results from a cohort study of almost 1,200 women showed that use of HRT was associated with higher delayed memory scores and larger entorhinal and hippocampal brain volumes – areas that are affected early by Alzheimer’s disease (AD) pathology.
HRT was also found to be most effective, as seen by larger hippocampal volume, when introduced during early perimenopause.
“Clinicians are very much aware of the susceptibility of women to cognitive disturbances during menopause,” lead author Rasha Saleh, MD, senior research associate, University of East Anglia (England), said in an interview.
“Identifying the at-risk APOE4 women and early HRT introduction can be of benefit. Confirming our findings in a clinical trial would be the next step forward,” Dr. Saleh said.
The findings were published online in Alzheimer’s Research and Therapy.
Personalized approaches
Dr. Saleh noted that estrogen receptors are localized in various areas of the brain, including cognition-related areas. Estrogen regulates such things as neuroinflammatory status, glucose utilization, and lipid metabolism.
“The decline of estrogen during menopause can lead to disturbance in these functions, which can accelerate AD-related pathology,” she said.
HRT during the menopausal transition and afterward is “being considered as a strategy to mitigate cognitive decline,” the investigators wrote. Early observational studies have suggested that oral estrogen “may be protective against dementia,” but results of clinical trials have been inconsistent, and some have even shown “harmful effects.”
The current researchers were “interested in the personalized approaches in the prevention of AD,” Dr. Saleh said. Preclinical and pilot data from her group have shown that women with APOE4 have “better cognitive test scores with nutritional and hormonal interventions.”
This led Dr. Saleh to hypothesize that HRT would be of more cognitive benefit for those with versus without APOE4, particularly when introduced early during the menopausal transition.
To investigate this hypothesis, the researchers analyzed baseline data from participants in the European Prevention of Alzheimer’s Dementia (EPAD) cohort. This project was initiated in 2015 with the aim of developing longitudinal models over the entire course of AD prior to dementia clinical diagnosis.
Participants were recruited from 10 European countries. All were required to be at least 50 years old, to have not been diagnosed with dementia at baseline, and to have no medical or psychiatric illness that could potentially exclude them from further research.
The current study included 1,178 women (mean age, 65.1 years), who were divided by genotype into non-APOE4 and APOE4 groups. HRT treatment for current or previous users included estrogen alone or estrogen plus progestogens via oral or transdermal administration routes, and at different doses.
The four tests used to assess cognition were the Mini-Mental State Examination dot counting to evaluate verbal working memory, the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) total score, the Four Mountain Test, and the supermarket trolley virtual reality test.
Brain MRI data were collected. The researchers focused on the medial temporal lobe as the “main brain region regulating cognition and memory processing.” This lobe includes the hippocampus, the parahippocampus, the entorhinal cortex, and the amygdala.
‘Critical window’
The researchers found a “trend” toward an APOE-HRT interaction (P-interaction = .097) for the total RBANS score. In particular, it was significant for the RBANS delayed memory index, where scores were consistently higher for women with APOE4 who had received HRT, compared with all other groups (P-interaction = .009).
Within-genotype group comparisons showed that HRT users had a higher RBANS total scale score and delayed memory index (P = .045 and P = .002, respectively), but only among APOE4 carriers. Effect size analyses showed a large effect of HRT use on the Four Mountain Test score and the supermarket trolley virtual reality test score (Cohen’s d = 0.988 and 1.2, respectively).
“This large effect was found only in APOE4 carriers,” the investigators noted.
Similarly, a moderate to large effect of HRT on the left entorhinal volume was observed in APOE4 carriers (Cohen’s d = 0.63).
In members of the APOE4 group who received HRT, the left entorhinal and left and right amygdala volumes were larger, compared with both no-APOE4 and non-HRT users (P-interaction = .002, .003, and .005, respectively). Similar trends were observed for the right entorhinal volume (P = .074).
In addition, among HRT users, the left entorhinal volume was larger (P = .03); the right and left anterior cingulate gyrus volumes were smaller (P = .003 and .062, respectively); and the left superior frontal gyrus volume was larger (P = .009) in comparison with women who did not receive HRT, independently of their APOE genotype.
Early use of HRT among APOE4 carriers was associated with larger right and left hippocampal volume (P = .035 and P = .028, respectively) – an association not found in non-APOE4 carriers. The association was also not significant when participants were not stratified by APOE genotype.
“The key important point here is the timing, or the ‘critical window,’ when HRT can be of most benefit,” Dr. Saleh said. “This is most beneficial when introduced early, before the neuropathology becomes irreversible.”
Study limitations include its cross-sectional design, which precludes the establishment of a causal relationship, and the fact that information regarding the type and dose of estrogen was not available for all participants.
HRT is not without risk, Dr. Saleh noted. She recommended that clinicians “carry out various screening tests to make sure that a woman is eligible for HRT and not at risk of hypercoagulability, for instance.”
Risk-benefit ratio
In a comment, Howard Fillit, MD, cofounder and chief science officer at the Alzheimer’s Drug Discovery Foundation, called the study “exactly the kind of work that needs to be done.”
Dr. Fillit, who was not involved with the current research, is a clinical professor of geriatric medicine, palliative care medicine, and neuroscience at Mount Sinai Hospital, New York.
He compared the process with that of osteoporosis. “We know that if women are treated [with HRT] at the time of the menopause, you can prevent the rapid bone loss that occurs with rapid estrogen loss. But if you wait 5, 10 years out, once the bone loss has occurred, the HRT doesn’t really have any impact on osteoporosis risk because the horse is already out of the barn,” he said.
Although HRT carries risks, “they can clearly be managed; and if it’s proven that estrogen or hormone replacement around the time of the menopause can be protective [against AD], the risk-benefit ratio of HRT could be in favor of treatment,” Dr. Fillit added.
The study was conducted as part of the Medical Research Council NuBrain Consortium. The investigators and Dr. Fillit reported no relevant financial relationships.

FROM ALZHEIMER’S RESEARCH AND THERAPY
Nearly 50% of patients with dementia experience falls
, suggests new research that also identifies multiple risk factors for these falls.
In a study of more than 5,500 participants, 45.5% of those with dementia experienced one or more falls, compared with 30.9% of their peers without dementia.
Vision impairment and living with a spouse were among the strongest predictors of future fall risk among participants living with dementia. Interestingly, high neighborhood social deprivation, which is reflected by such things as income and education, was associated with lower odds of falling.
Overall, the results highlight the need for a multidisciplinary approach to preventing falls among elderly individuals with dementia, said lead author Safiyyah M. Okoye, PhD, assistant professor, College of Nursing and Health Professions, Drexel University, Philadelphia.
“We need to consider different dimensions and figure out how we can try to go beyond the clinic in our interactions,” she said.
Dr. Okoye noted that in addition to reviewing medications that may contribute to falls and screening for vision problems, clinicians might also consider resources to improve the home environment and ensure that families have appropriate caregiving.
The findings were published online in Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association.
No ‘silver bullet’
Every year, falls cause millions of injuries in older adults, and those with dementia are especially vulnerable. This population has twice the risk of falling and up to three times the risk of incurring serious fall-related injuries, such as fractures, the researchers noted.
Falls are a leading cause of hospitalization among those with dementia. Previous evidence has shown that persons with dementia are more likely to experience negative health consequences, such as delirium, while in hospital, compared with those without dementia. Even minor fall-related injuries are associated with the patient’s being discharged to a nursing home rather than returning home.
Dr. Okoye stressed that many factors contribute to falls, including health status; function, such as the ability to walk and balance; medications; home environment; and activity level.
“There are multidimensional aspects, and we can’t just find one silver bullet to address falls. It should be addressed comprehensively,” she said.
Existing studies “overwhelmingly” focus on factors related to health and function that could be addressed in the doctor’s office or with a referral, rather than on environmental and social factors, Dr. Okoye noted.
And even though the risk of falling is high among community-dwelling seniors with dementia, very few studies have addressed the risk of falls among these adults, she added.
The new analysis included a nationally representative sample of 5,581 community-dwelling adults who participated in both the 2015 and 2016 National Health and Aging Trends Study (NHATS). The NHATS is a population-based survey of health and disability trends and trajectories among Americans aged 65 years and older.
During interviews, participants were asked, personally or by proxy, about falls during the previous 12 months. Having fallen at baseline was evaluated as a possible predictor of falls in the subsequent 12 months.
To determine probable dementia, researchers asked whether a doctor had ever told the participants that they had dementia or Alzheimer’s disease. They also used a dementia screening questionnaire and neuropsychological tests of memory, orientation, and executive function.
Of the total sample, most (n = 5,093) did not have dementia.
Physical environmental factors that were assessed included conditions at home, such as clutter, tripping hazards, and structural issues, as well as neighborhood social and economic deprivation – such as income, education levels, and employment status.
Fall rates and counterintuitive findings
Results showed that significantly more of those with dementia than without experienced one or more falls (45.5% vs. 30.9%; P < .001).
In addition, a history of falling was significantly associated with subsequent falls among those with dementia (odds ratio, 6.20; 95% confidence interval, 3.81-10.09), as was vision impairment (OR, 2.22; 95% CI, 1.12-4.40) and living with a spouse versus alone (OR, 2.43; 95% CI, 1.09-5.43).
A possible explanation for higher fall risk among those living with a partner is that those living alone usually have better functioning, the investigators noted. Also, live-in partners tend to be of a similar age as the person with dementia and may have challenges of their own.
Interestingly, high neighborhood social deprivation was associated with lower odds of falling (OR, 0.55 for the highest deprivation scores; 95% CI, 0.31-0.98), a finding Dr. Okoye said was “counterintuitive.”
This result could be related to the social environment, she noted. “Maybe there are more people around in the house, more people with eyes on the person, or more people in the community who know the person. Despite the low economic resources, there could be social resources there,” she said.
The new findings underscore the idea that falling is a multidimensional phenomenon among older adults with dementia as well as those without dementia, Dr. Okoye noted.
Doctors can play a role in reducing falls among patients with dementia by asking about falls, possibly eliminating medications that are associated with risk of falling, and screening for and correcting vision and hearing impairments, she suggested.
They may also help determine household hazards for a patient, such as clutter and poor lighting, and ensure that these are addressed, Dr. Okoye added.
No surprise
Commenting on the study, David S. Knopman, MD, a clinical neurologist at Mayo Clinic, Rochester, Minn., said the finding that visual impairment and a prior history of falling are predictive of subsequent falls “comes as no surprise.”
Dr. Knopman, whose research focuses on late-life cognitive disorders, was not involved with the current study.
Risk reduction is “of course” a key management goal, he said. “Vigilance and optimizing the patient’s living space to reduce fall risks are the major strategies,” he added.
Dr. Knopman reiterated that falls among those with dementia are associated with higher mortality and often lead to loss of the capacity to live outside of an institution.
The study was supported by the National Institute on Aging. The investigators and Dr. Knopman report no relevant financial relationships.

In a study of more than 5,500 participants, 45.5% of those with dementia experienced one or more falls, compared with 30.9% of their peers without dementia.
Vision impairment and living with a spouse were among the strongest predictors of future fall risk among participants living with dementia. Interestingly, high neighborhood social deprivation, which is reflected by such things as income and education, was associated with lower odds of falling.
Overall, the results highlight the need for a multidisciplinary approach to preventing falls among elderly individuals with dementia, said lead author Safiyyah M. Okoye, PhD, assistant professor, College of Nursing and Health Professions, Drexel University, Philadelphia.
“We need to consider different dimensions and figure out how we can try to go beyond the clinic in our interactions,” she said.
Dr. Okoye noted that in addition to reviewing medications that may contribute to falls and screening for vision problems, clinicians might also consider resources to improve the home environment and ensure that families have appropriate caregiving.
The findings were published online in Alzheimer’s and Dementia: The Journal of the Alzheimer’s Association.
No ‘silver bullet’
Every year, falls cause millions of injuries in older adults, and those with dementia are especially vulnerable. This population has twice the risk of falling and up to three times the risk of incurring serious fall-related injuries, such as fractures, the researchers noted.
Falls are a leading cause of hospitalization among those with dementia. Previous evidence has shown that persons with dementia are more likely to experience negative health consequences, such as delirium, while in hospital, compared with those without dementia. Even minor fall-related injuries are associated with the patient’s being discharged to a nursing home rather than returning home.
Dr. Okoye stressed that many factors contribute to falls, including health status; function, such as the ability to walk and balance; medications; home environment; and activity level.
“There are multidimensional aspects, and we can’t just find one silver bullet to address falls. It should be addressed comprehensively,” she said.
Existing studies “overwhelmingly” focus on factors related to health and function that could be addressed in the doctor’s office or with a referral, rather than on environmental and social factors, Dr. Okoye noted.
And even though the risk of falling is high among community-dwelling seniors with dementia, very few studies have addressed the risk of falls among these adults, she added.
The new analysis included a nationally representative sample of 5,581 community-dwelling adults who participated in both the 2015 and 2016 National Health and Aging Trends Study (NHATS). The NHATS is a population-based survey of health and disability trends and trajectories among Americans aged 65 years and older.
During interviews, participants were asked, personally or by proxy, about falls during the previous 12 months. Having fallen at baseline was evaluated as a possible predictor of falls in the subsequent 12 months.
To determine probable dementia, researchers asked whether a doctor had ever told the participants that they had dementia or Alzheimer’s disease. They also used a dementia screening questionnaire and neuropsychological tests of memory, orientation, and executive function.
Of the total sample, most (n = 5,093) did not have dementia.
Physical environmental factors that were assessed included conditions at home, such as clutter, tripping hazards, and structural issues, as well as neighborhood social and economic deprivation – such as income, education levels, and employment status.

Ecopipam reduces Tourette’s tics without common side effects in phase 2 trial
Ecopipam, in development for Tourette syndrome in children and adolescents, has shown in a randomized, controlled trial that, compared with placebo, it reduced tics and reduced the risk for some of the common side effects of other treatments, including weight gain.
Findings of the multicenter, double-blind, trial funded by the drug maker, Emalex Biosciences, were published online in Pediatrics. The trial was conducted at 68 sites in the United States, Canada, Germany, France, and Poland between May 2019 and September 2021.
Donald L. Gilbert, MD, MS, with the division of neurology at Cincinnati Children’s Hospital, and colleagues noted that all Food and Drug Administration–approved medications for Tourette syndrome are antipsychotics. The medications carry a risk of weight gain, electrocardiogram abnormalities, metabolic changes, and drug-induced movement disorders.
First-in-class medication ecopipam, targets the D1 dopamine receptor, while currently approved medications block the D2 receptor. It “may be a safe and effective treatment of Tourette syndrome with advantages over other currently approved therapeutic agents,” the authors wrote.
The study included 153 individuals at least 6 years old up to age 18 with a baseline Yale Global Tic Severity Score Total Tic Score of at least 20.
They were randomly assigned 1:1 to ecopipam or placebo.
Significant reduction in tic severity
Researchers saw a 30% reduction in the tic severity score from baseline to week 12 for the ecopipam group compared with the placebo group.
The data showed a least-squares mean difference of 3.44 (95% confidence interval [CI], 6.09-0.79, P = .01). Researchers also saw improvement in Clinical Global Impression of Tourette Syndrome Severity in the ecopipam group (P = .03).
Sara Pawlowski, MD, division chief for primary care mental health integration at University of Vermont Health Network and assistant professor of psychiatry, University of Vermont, Burlington, said in an interview that several things should be considered with this research.
One is that, though the results show a reduction in tics, the study lasted only 12 weeks and “tics can last a lifetime,” she noted.
“They also can ebb and flow with major life events, stressors, and various other variables. So, I wonder how the effects of improvement can be teased out from the natural ebb and flow of the condition in a 3-month window, which is a snapshot into the course of a known relapsing, remitting, lifetime, and chronically variable condition,” she said.
Headaches, insomnia among side effects
Weight gain was larger in the placebo group than in the ecopipam group: 17.1% in the ecopipam group and 20.3% of those who got a placebo had a weight gain of more than 7% over the study period.
The most common side effects of the study drug were headache (15.8%), insomnia (14.5%), fatigue (7.9%), and somnolence (7.9%).
A limitation of the study was lack of racial and ethnic diversity, as 93.5% of those in the placebo group and 86.8% in the ecopipam group were White.
Guidelines in North America and Europe agree that behavioral treatments should be the first-line therapy.
Dr. Pawlowski said that although effective medications are needed, she urges focusing on better access to nonmedication treatments “that work for children and adolescents” as children who start taking the medications early may take them for the rest of their lives.
Also, while the research didn’t find weight gain in the ecopipam group, the side effects they did find in the group, including headache and insomnia, “do impact a child’s life,” she noted.
“We also can’t be reassured that over the course of chronic treatment there wouldn’t be movement disorders or metabolic disorders that emerge. Those are side effects or disorders that can emerge surreptitiously over time, and more time than 12 weeks,” she said.
The study was funded by Emalex Biosciences. Dr. Gilbert has received consulting fees from Biogen and PTC therapeutics. Study coauthors disclosed ties with Emalex, Alkermes, and Paragon Biosciences. Dr. Pawlowski reports no relevant financial relationships.

FROM PEDIATRICS
Hearing loss strongly tied to increased dementia risk
, new national data show. Investigators also found that even mild hearing loss was associated with increased dementia risk, although it was not statistically significant, and that hearing aid use was tied to a 32% decrease in dementia prevalence.
“Every 10-decibel increase in hearing loss was associated with 16% greater prevalence of dementia, such that prevalence of dementia in older adults with moderate or greater hearing loss was 61% higher than prevalence in those with normal hearing,” said lead investigator Alison Huang, PhD, senior research associate in epidemiology at Johns Hopkins Bloomberg School of Public Health and core faculty in the Cochlear Center for Hearing and Public Health, Baltimore.
The findings were published online in JAMA.
Dose dependent effect
For their study, researchers analyzed data on 2,413 community-dwelling participants in the National Health and Aging Trends Study, a nationally representative, continuous panel study of U.S. Medicare beneficiaries aged 65 and older.
Data from the study was collected during in-home interviews, setting it apart from previous work that relied on data collected in a clinical setting, Dr. Huang said.
“This study was able to capture more vulnerable populations, such as the oldest old and older adults with disabilities, typically excluded from prior epidemiologic studies of the hearing loss–dementia association that use clinic-based data collection, which only captures people who have the ability and means to get to clinics,” Dr. Huang said.
Weighted hearing loss prevalence was 36.7% for mild and 29.8% for moderate to severe hearing loss, and weighted prevalence of dementia was 10.3%.
Those with moderate to severe hearing loss were 61% more likely to have dementia than were those with normal hearing (prevalence ratio, 1.61; 95% confidence interval [CI], 1.09-2.38).
Dementia prevalence increased with increasing severity of hearing loss: Normal hearing: 6.19% (95% CI, 4.31-8.80); mild hearing loss: 8.93% (95% CI, 6.99-11.34); moderate to severe hearing loss: 16.52% (95% CI, 13.81-19.64). But only moderate to severe hearing loss showed a statistically significant association with dementia (P = .02).
Dementia prevalence increased 16% per 10-decibel increase in hearing loss (prevalence ratio 1.16; P < .001).
Among the 853 individuals in the study with moderate to severe hearing loss, those who used hearing aids (n = 414) had a 32% lower risk of dementia compared with those who didn’t use assisted devices (prevalence ratio, 0.68; 95% CI, 0.47-1.00). Similar data were published in JAMA Neurology, suggesting that hearing aids reduce dementia risk.
“With this study, we were able to refine our understanding of the strength of the hearing loss–dementia association in a study more representative of older adults in the United States,” said Dr. Huang.
Robust association
Commenting on the findings, Justin S. Golub, MD, associate professor in the department of otolaryngology–head and neck surgery at Columbia University, New York, said the study supports earlier research and suggests a “robust” association between hearing loss and dementia.
“The particular advantage of this study was that it was high quality and nationally representative,” Dr. Golub said. “It is also among a smaller set of studies that have shown hearing aid use to be associated with lower risk of dementia.”
Although not statistically significant, researchers did find increasing prevalence of dementia among people with only mild hearing loss, and clinicians should take note, said Dr. Golub, who was not involved with this study.
“We would expect the relationship between mild hearing loss and dementia to be weaker than severe hearing loss and dementia and, as a result, it might take more participants to show an association among the mild group,” Dr. Golub said.
“Even though this particular study did not specifically find a relationship between mild hearing loss and dementia, I would still recommend people to start treating their hearing loss when it is early,” Dr. Golub added.
The study was funded by the National Institute on Aging. Dr. Golub reports no relevant financial relationships. Full disclosures for study authors are included in the original article.

“The particular advantage of this study was that it was high quality and nationally representative,” Dr. Golub said. “It is also among a smaller set of studies that have shown hearing aid use to be associated with lower risk of dementia.”
Although not statistically significant, researchers did find increasing prevalence of dementia among people with only mild hearing loss, and clinicians should take note, said Dr. Golub, who was not involved with this study.
“We would expect the relationship between mild hearing loss and dementia to be weaker than severe hearing loss and dementia and, as a result, it might take more participants to show an association among the mild group,” Dr. Golub said.
“Even though this particular study did not specifically find a relationship between mild hearing loss and dementia, I would still recommend people to start treating their hearing loss when it is early,” Dr. Golub added.
The study was funded by the National Institute on Aging. Dr. Golub reports no relevant financial relationships. Full disclosures for study authors are included in the original article.

, new national data show. Investigators also found that even mild hearing loss was associated with increased dementia risk, although it was not statistically significant, and that hearing aid use was tied to a 32% decrease in dementia prevalence.
“Every 10-decibel increase in hearing loss was associated with 16% greater prevalence of dementia, such that prevalence of dementia in older adults with moderate or greater hearing loss was 61% higher than prevalence in those with normal hearing,” said lead investigator Alison Huang, PhD, senior research associate in epidemiology at Johns Hopkins Bloomberg School of Public Health and core faculty in the Cochlear Center for Hearing and Public Health, Baltimore.
The findings were published online in JAMA.
Dose dependent effect
For their study, researchers analyzed data on 2,413 community-dwelling participants in the National Health and Aging Trends Study, a nationally representative, continuous panel study of U.S. Medicare beneficiaries aged 65 and older.
Data from the study was collected during in-home interviews, setting it apart from previous work that relied on data collected in a clinical setting, Dr. Huang said.
“This study was able to capture more vulnerable populations, such as the oldest old and older adults with disabilities, typically excluded from prior epidemiologic studies of the hearing loss–dementia association that use clinic-based data collection, which only captures people who have the ability and means to get to clinics,” Dr. Huang said.
Weighted hearing loss prevalence was 36.7% for mild and 29.8% for moderate to severe hearing loss, and weighted prevalence of dementia was 10.3%.
Those with moderate to severe hearing loss were 61% more likely to have dementia than were those with normal hearing (prevalence ratio, 1.61; 95% confidence interval [CI], 1.09-2.38).
Dementia prevalence increased with increasing severity of hearing loss: Normal hearing: 6.19% (95% CI, 4.31-8.80); mild hearing loss: 8.93% (95% CI, 6.99-11.34); moderate to severe hearing loss: 16.52% (95% CI, 13.81-19.64). But only moderate to severe hearing loss showed a statistically significant association with dementia (P = .02).
Dementia prevalence increased 16% per 10-decibel increase in hearing loss (prevalence ratio 1.16; P < .001).
Among the 853 individuals in the study with moderate to severe hearing loss, those who used hearing aids (n = 414) had a 32% lower risk of dementia compared with those who didn’t use assisted devices (prevalence ratio, 0.68; 95% CI, 0.47-1.00). Similar data were published in JAMA Neurology, suggesting that hearing aids reduce dementia risk.
“With this study, we were able to refine our understanding of the strength of the hearing loss–dementia association in a study more representative of older adults in the United States,” said Dr. Huang.
