The cell that might trigger Alzheimer’s disease
It all started with genetic data. A gene here, a gene there. Eventually the story became clearer: If scientists are to one day find a cure for Alzheimer’s disease, they should look to the immune system.
Over the past couple decades, researchers have identified numerous genes involved in various immune system functions that may also contribute to Alzheimer’s disease. Some of the prime suspects are genes that control microglia, now the focus of intense research in developing new Alzheimer’s drugs.
Microglia are amoeba-like cells that scour the brain for injuries and invaders. They help clear dead or impaired brain cells and literally gobble up invading microbes. Without them, we’d be in trouble.
In a normal brain, a protein called beta-amyloid is cleared away through our lymphatic system by microglia as molecular junk. But sometimes it builds up. Certain gene mutations are one culprit in this toxic accumulation. Traumatic brain injury is another, and, perhaps, impaired microglial function.
One thing everyone agrees on is that in people with Alzheimer’s disease, too much amyloid accumulates between their brain cells and in the vessels that supply the brain with blood. Once amyloid begins to clog networks of neurons, it triggers the accumulation of another protein, called tau, inside of these brain cells. The presence of tau sends microglia and other immune mechanisms into overdrive, resulting in the inflammatory immune response that many experts believe ultimately saps brain vitality in Alzheimer’s disease.
The gene scene
To date, nearly a dozen genes involved in immune and microglial function have been tied to Alzheimer’s disease. The first was CD33, identified in 2008.
“When we got the results, I literally ran to my colleague’s office next door and said, you gotta see this!” said Harvard neuroscientist Rudolph Tanzi. Dr. Tanzi, who goes by Rudy, led the CD33 research. The discovery was quickly named a top medical breakthrough of 2008 by Time magazine.
“We were laughing because what they didn’t know is we had no idea what this gene did,” he joked. But over time, research by Dr. Tanzi and his group revealed that CD33 is a kind of microglial on-off switch, activating the cells as part of an inflammatory pathway.
“We kind of got it all going when it came to the genetics,” he said.
Microglia normally recognize molecular patterns associated with microbes and cellular damage as unwanted. This is how they know to take action – to devour unfamiliar pathogens and dead tissue. Dr. Tanzi believes microglia sense any sign of brain damage as an infection, which causes them to become hyperactive.
Much of our modern human immune system, he explained, evolved many hundreds of thousands of years ago. Our lifespans at the time were far shorter than they are today, and the majority of people didn’t live long enough to develop dementia or the withered brain cells that come with it. So our immune system, he said, assumes any faulty brain tissue is due to a microbe, not dementia. Microglia react aggressively, clearing the area to prevent the spread of infection.
“They say, ‘We better wipe out this part of the brain that’s infected, even if it’s not.’ They don’t know,” quipped Dr. Tanzi. “That’s what causes neuroinflammation. And CD33 turns this response on. The microglia become killers, not just janitors.”
A brake on overactive microglia
If CD33 is the yin, a gene called TREM2 is the yang. Discovered a few years after CD33, TREM2 reins in microglial activation, returning them to their role as cellular housekeepers.
Neurologist David Holtzman, MD, of Washington University in St. Louis, who studies TREM2, agrees that wherever you find amyloid, tau, or dead brain cells, there are microglia raring to go and ready to scavenge.
“I think at first a lot of people thought these cells were reacting to Alzheimer’s pathology, and not necessarily a cause of the disease,” he said.
It was the discovery of TREM2 on the heels of CD33 that really shifted the thinking, in part because it produces a protein that in the brain is only found in microglia. “Many of us [in the field] immediately said, ‘Look, there’s now a risk factor that is only expressed in microglia. It must be that innate immune cells are important in some way in the pathogenesis of the disease,’ “ he added.
Dr. Holtzman sees microglial activation in impending dementia as a double-edged sword. In the beginning, microglia clear unwanted amyloid to maintain brain health. But once accumulated amyloid and tau have done enough damage, the neuroinflammation that comes with microglial activation does more harm than good. Neurons die en masse and dementia sets in.
But not all researchers are convinced.
Serge Revist, PhD, is a professor in the department of molecular medicine at the Laval University Medical School in Quebec. Based on his lab’s research, he believes that while impaired immune activity is involved in Alzheimer’s disease, it is not the root cause. “I don’t think it is the immune cells that do the damage, I still think it is the beta-amyloid itself,” he said, “In my lab, in mouse studies, we’ve never found that immune cells were directly responsible for killing neurons.”
He does believe that in some patients with Alzheimer’s disease, microglia may not be able to handle the excess amyloid that accumulates in the disease and that developing treatments that improve the ability of microglia and the immune system to clear the protein could be effective.
Microglial medicines
The biological cascade leading to Alzheimer’s disease is a tangled one. Gene variants influencing the accumulation and clearance of amyloid are likely a major contributor. But immune activity caused by early life infection might also be involved, at least in some cases. This infectious theory of Alzheimer’s disease was first proposed by Dr. Tanzi’s now-deceased colleague Robert Moir, PhD. Dr. Tanzi’s group even has evidence that amyloid itself is antimicrobial and evolved to protect us from pathogens, only to become a problem when overactive and aggregated.
And the same goes for microglia, cells whose over-ambition might cause much of the brain degeneration seen in Alzheimer’s disease.
In theory, if a treatment could decrease CD33 activity or increase that of TREM2, doctors might one day may be able to slow or even stop the progression of dementia. Instead of going after amyloid itself – the mechanism behind so many failed investigational Alzheimer’s drugs – a therapy that quells the immune response to amyloid might be the answer in treating dementia.
“There are a number of scientists and companies trying to figure out how to influence genes like TREM2 and CD33 and to both decrease amyloid and act on the downstream consequences of the protein,” said Dr. Holtzman. “All of this is to say that somewhere in the biology that causes Alzheimer’s disease, the immune system is involved.”
It seems that in many cases, the most common form of a dementia might be due to a well-intentioned immune cell going rogue. “I think you’d hear this from basically any researcher worth their salt,” said Dr. Tanzi. “I feel strongly that without microglial activation, you will not get Alzheimer’s disease.”

Dr. Jeremiah Stamler, pioneer of preventive cardiology, dies at 102
On the occasion of his 100th birthday, The Washington Post wrote of the trailblazing cardiologist and scientist Jeremiah Dr. Stamler, MD: “You may not know him, but he may have saved your life.”
Hyperbole, it was not.
Over a career spanning more than 70 years, Dr. Stamler transformed medicine and the public’s understanding of diet and lifestyle in cardiovascular health and helped introduce the concept of readily measured ‘risk factors’ such as cholesterol, hypertension, smoking, and diabetes.
Dr. Stamler, the founding chair and a professor emeritus of preventive medicine at Northwestern University’s Feinberg School of Medicine, Chicago, died Wednesday at his home in Sag Harbor, New York, at age 102.
“It is no exaggeration to say that few people in history have had as great an impact on human health,” Donald Lloyd-Jones, MD, chair of the department of preventive medicine at Feinberg and president of the American Heart Association, said in a statement.
“Jerry was a giant intellect who founded the fields of cardiovascular epidemiology and preventive cardiology and led [the way] in defining new prevention concepts right up until his last days,” Dr. Lloyd-Jones added in a statement issued by the university.
Tom Frieden, MD, former director of the Centers for Disease Control and Prevention, tweeted, “Jerry and my father did research on sodium together in the early 1950s. He was a giant in the field of public health, and we’re still benefiting from his brilliance and dedication.”
Roger Blumenthal, MD, director of the Johns Hopkins Ciccarone Center for Prevention of Cardiovascular Disease, tweeted, “R.I.P., Dr. Jeremiah Stamler, ‘the father of preventive cardiology,’ dies at 102 – a true legendary force for health.”
The son of Russian immigrants, Dr. Stamler was born in Brooklyn in 1919 and received a bachelor’s degree from Columbia University and a medical degree from State University of New York.
Discharged from the U.S. Army with the rank of captain, Dr. Stamler and his first wife, Rose, herself a distinguished cardiology researcher, moved to Chicago in 1947 and began researching nutrition and atherosclerosis under pioneering cardiology researcher Louis N. Katz, MD, ultimately showing that atherosclerosis could be introduced by changing the diet of chickens. She died in 1998.
Dr. Stamler also worked for Chicago’s Public Health Department in the 1950s, starting a rheumatic fever prevention program for children and the Chicago Coronary Prevention Evaluation Program, working with higher-risk middle-aged men.
Dr. Stamler’s international INTERSALT study established an independent relationship between blood pressure and increased sodium intake, as well as body mass index and heavy alcohol intake. First published in 1988, the research faced opposition from fellow scientists and the food industry alike.
In a 2006 interview, Dr. Stamler said he and fellow researchers began pressing the American Heart Association in the late 1950s to adopt a public policy of support to improve lifestyles, including smoking cessation and better nutrition. “It took some doing. The AHA was initially reluctant and was under pressure from industry.”
Their efforts were rewarded with the AHA’s first statement on smoking in 1959 and first statement on diet in 1960, whereas, Dr. Stamler noted, “the first World Health Organization statement did not come out until the 1980s.”
Philip Greenland, MD, professor of cardiology and former chair of preventive medicine at Northwestern, described Dr. Stamler as a “force for truth that never backed down when confronted by others who did not share his passion for truth and the best science.”
“I loved working with him since I always knew he would make our research better, clearer, more relevant, and more impactful,” he said in the AHA statement.
A lifelong activist and opponent of the Vietnam War, Dr. Stamler was subpoenaed in May 1965 by the House Un-American Activities Committee (HUAC) along with his nutritionist-assistant Yolanda Hall. Rather than pleading the Fifth Amendment against self-incrimination, Dr. Stamler and Ms. Hall refused to testify before the committee and were charged with contempt of Congress.
With the help of local attorneys, Dr. Stamler filed a civil suit against the HUAC, charging that its mandate was unconstitutional. After 8½ years of litigation that went all the way to the Supreme Court, the government agreed to drop its indictment against Dr. Stamler and he dropped his civil suit against the committee.
A year after the Stamler v. Willis case ended, the House voted to terminate the HUAC. In an essay detailing the high-profile case, Henry Blackburn quipped, “They simply did not know who they were taking on when they tagged ol’ Jerry Stamler.”
“Dr. Stamler’s exceptional science was paralleled by his remarkable humanity. He was a champion of our best American ideals, he was fearless when facing the status quo, and he was tireless in the pursuit of what was right and just. He remains a beacon for all that is noble in medicine,” said Clyde Yancy, MD, MSc, Northwestern’s chair of cardiology.
Over the course of his career, Dr. Stamler published more than 670 peer-reviewed papers, 22 books and monographs, and his work has been cited more than 56,000 times. A committed mentor, Dr. Stamler was the 2014 recipient of the AHA’s Eugene Braunwald Academic Mentorship Award.
A lifelong proponent of the Mediterranean diet, Dr. Stamler divided his time between New York, a home in Italy, and Chicago, with his wife Gloria Beckerman Stamler, whom he married in 2004 and who preceded him in death.

Roger Blumenthal, MD, director of the Johns Hopkins Ciccarone Center for Prevention of Cardiovascular Disease, tweeted, “R.I.P., Dr. Jeremiah Stamler, ‘the father of preventive cardiology,’ dies at 102 – a true legendary force for health.”
The son of Russian immigrants, Dr. Stamler was born in Brooklyn in 1919 and received a bachelor’s degree from Columbia University and a medical degree from State University of New York.
Discharged from the U.S. Army with the rank of captain, Dr. Stamler and his first wife, Rose, herself a distinguished cardiology researcher, moved to Chicago in 1947 and began researching nutrition and atherosclerosis under pioneering cardiology researcher Louis N. Katz, MD, ultimately showing that atherosclerosis could be introduced by changing the diet of chickens. She died in 1998.
Dr. Stamler also worked for Chicago’s Public Health Department in the 1950s, starting a rheumatic fever prevention program for children and the Chicago Coronary Prevention Evaluation Program, working with higher-risk middle-aged men.
Dr. Stamler’s international INTERSALT study established an independent relationship between blood pressure and increased sodium intake, as well as body mass index and heavy alcohol intake. First published in 1988, the research faced opposition from fellow scientists and the food industry alike.
In a 2006 interview, Dr. Stamler said he and fellow researchers began pressing the American Heart Association in the late 1950s to adopt a public policy of support to improve lifestyles, including smoking cessation and better nutrition. “It took some doing. The AHA was initially reluctant and was under pressure from industry.”
Their efforts were rewarded with the AHA’s first statement on smoking in 1959 and first statement on diet in 1960, whereas, Dr. Stamler noted, “the first World Health Organization statement did not come out until the 1980s.”
Philip Greenland, MD, professor of cardiology and former chair of preventive medicine at Northwestern, described Dr. Stamler as a “force for truth that never backed down when confronted by others who did not share his passion for truth and the best science.”
“I loved working with him since I always knew he would make our research better, clearer, more relevant, and more impactful,” he said in the AHA statement.
A lifelong activist and opponent of the Vietnam War, Dr. Stamler was subpoenaed in May 1965 by the House Un-American Activities Committee (HUAC) along with his nutritionist-assistant Yolanda Hall. Rather than pleading the Fifth Amendment against self-incrimination, Dr. Stamler and Ms. Hall refused to testify before the committee and were charged with contempt of Congress.
With the help of local attorneys, Dr. Stamler filed a civil suit against the HUAC, charging that its mandate was unconstitutional. After 8½ years of litigation that went all the way to the Supreme Court, the government agreed to drop its indictment against Dr. Stamler and he dropped his civil suit against the committee.
A year after the Stamler v. Willis case ended, the House voted to terminate the HUAC. In an essay detailing the high-profile case, Henry Blackburn quipped, “They simply did not know who they were taking on when they tagged ol’ Jerry Stamler.”
“Dr. Stamler’s exceptional science was paralleled by his remarkable humanity. He was a champion of our best American ideals, he was fearless when facing the status quo, and he was tireless in the pursuit of what was right and just. He remains a beacon for all that is noble in medicine,” said Clyde Yancy, MD, MSc, Northwestern’s chair of cardiology.
Over the course of his career, Dr. Stamler published more than 670 peer-reviewed papers, 22 books and monographs, and his work has been cited more than 56,000 times. A committed mentor, Dr. Stamler was the 2014 recipient of the AHA’s Eugene Braunwald Academic Mentorship Award.
A lifelong proponent of the Mediterranean diet, Dr. Stamler divided his time between New York, a home in Italy, and Chicago, with his wife Gloria Beckerman Stamler, whom he married in 2004 and who preceded him in death.

What docs don’t know about the Disabilities Act can hurt them and patients
Lisa Iezzoni, MD, a professor of medicine at Harvard Medical School and a disability researcher at Massachusetts General Hospital, both in Boston, has used a wheelchair for more than 30 years because of multiple sclerosis. When she visits her primary care doctor, she doesn’t get weighed because the scales are not wheelchair accessible.
This failure to weigh her and other patients in wheelchairs could lead to serious medical problems. Weight is used to monitor a person’s overall health and prenatal health and to determine accurate doses for medications such as some chemotherapies, said Dr. Iezzoni.
In another situation, a man who used a wheelchair said that his primary care doctor never got him out of it for a complete physical exam. The patient later developed lymphoma, which first appeared in his groin. The doctor should have accommodated his disability and used a height-adjustable exam table or a portable lift to transfer him onto the table.
When physicians don’t provide access to medical care that patients with disabilities need, they put themselves at greater risk of lawsuits, fines, and settlements.
Yet, a new study in Health Affairs suggests that a large percentage of doctors are not fully aware of what they are legally required to do.
Under federal nondiscrimination laws (Americans With Disabilities Act, American Rehabilitation Act, and ADA Amendments Act), medical practices must provide equal access to people with disabilities, accommodate their disability-related needs, and not refuse them medical services because of their disabilities, say disability experts.
Where doctors go wrong with disability laws
What doctors don’t know about providing reasonable accommodations makes them vulnerable to lawsuits, which worries more than two-thirds of the 714 outpatient doctors surveyed.
Not only are they required to provide reasonable accommodations, but they also have to pay for them, the researchers said. One-fifth of the surveyed doctors said they didn’t know that practice owners have to pay.
More than one practice has made patients pay for services needed for their disability, such as sign language interpreters – the patients later complained this violated the ADA to enforcement agencies.
Doctors also don’t know that they have to collaborate with patients to determine what reasonable accommodations they need – over two-thirds of those surveyed said they didn’t know it was a joint responsibility, the study found.
When doctors fail to accommodate patients’ disability needs, they engage in discrimination and violate the ADA, says Elizabeth Pendo, JD, a coauthor of the study and the Joseph J. Simeone Professor of Law at Saint Louis University.
The Department of Justice has investigated several patient complaints of alleged disability discrimination recently and resolved the disputes with agreements and small fines in some cases. “The goal is not to get large financial settlements but to work with practices to get the correct procedures in place to be compliant,” said Ms. Pendo.
Physicians would be wise to check out whether their practices are as accessible as they think. Even if there’s a ramp to the office building, the parking lot may not have a van-accessible space or enough handicapped parking signs, or the exam room may be too narrow for a wheelchair to navigate.
These practices violated the ADA and agreed to make changes:
- Hamden, Conn., has two buildings that patients with physical disabilities couldn’t easily enter. The physician owners agreed to change the buildings’ entrances and access routes and add features to make it easier to use examination rooms and restrooms and the check-in and check-out areas.
- Seven medical offices in Riverside, Calif., failed to communicate effectively with deaf and hard-of-hearing patients. They should have had a qualified sign language interpreter, an assistive listening device, or another appropriate aid or service available to a deaf patient and her family. Instead, the office relied on a video remote interpretation system that often failed to work. The agreement requires the clinic to provide those aids and services to patients and their companions who are deaf or hard of hearing, advertise their availability, assess each patient who is deaf or hard of hearing to determine the best aids and services for their needs, and pay $5,000 in compensation to the complainant and a $1,000 civil penalty to the United States.
- Springfield, Mass., refused to provide full joint replacements to two patients being treated with buprenorphine, a medication used to treat opioid use disorder. Rather than accommodate the patients, the surgeons referred them elsewhere because they were uncomfortable with the postoperative pain management protocol for patients prescribed buprenorphine. “The Americans With Disabilities Act protects health care access for people under medical treatment for opioid use disorder,” said Acting U.S. Attorney Nathaniel R. Mendell. “Health care providers must comply with the ADA, even when doing so is inconvenient or makes them uncomfortable.” The agreement requires the practice to adopt a nondiscrimination policy, provide training on the ADA and opioid use disorder, and pay two complainants $15,000 each for pain and suffering.
The DOJ has filed civil lawsuits against medical practices when they failed to resolve the allegations. Recent cases include an ophthalmology practice with 24 facilities in Arizona that refused to help transfer patients in wheelchairs to surgery tables for eye surgery and required them to pay for transfer support services and two obstetricians-gynecologists in Bakersfield, Calif., who refused to provide routine medical care to a patient because of her HIV status.
What doctors should know
Many people tend to think of a person with a disability as being in a wheelchair. But the ADA has a very broad definition of disability, which includes any physical or mental impairment that substantially limits any major life activity, said Ms. Pendo.
“It was amended in 2008 to clarify that the definition includes people with chronic diseases such as diabetes and cancer, cognitive and neurological disorders, substance abuse disorders, vision and hearing loss, and learning and other disabilities,” she said.
That means that doctors have to accommodate many types of disabilities, which can be challenging. The ADA only specifies that fixed structures need to be accessible, such as parking lots, driveways, and buildings, said Dr. Iezzoni.
When it comes to “reasonable accommodations,” doctors should decide that on a case-by-case basis, she said.
“We can say based on our study that 71% of doctors don’t know the right way to think about the accommodations – they don’t know they need to talk to patients so they can explain to them exactly what they need to accommodate their disability,” said Dr. Iezzoni.
Doctors are also required to provide effective communication for patients with sensory or cognitive disabilities, which can depend on the severity, said Ms. Pendo. Is the person deaf or hard of hearing, blind or partially sighted – is the dementia mild or severe?
“The requirement is there, but what that looks like will vary by patient. That’s what’s challenging,” said Ms. Pendo.
Dr. Iezzoni recommends that doctor’s offices ask patients whether they need special help or individual assistance when they make appointments and enter their responses in their records. She also suggests that patients be asked at follow-up appointments whether they still need the same help or not.
“Disabilities can change over time – a person with bad arthritis may need help getting onto an exam table, but later get a knee or hip replacement that is effective and no longer need that help,” said Dr. Iezzoni.
Benefits outweigh costs
Physicians have made progress in meeting the ADA’s physical accessibility requirements, said Dr. Iezzoni. “The literature suggests that doctors have done a good job at fixing the structural barriers people with mobility issues face, such as ramps and bathrooms.”
However, there are exceptions in rural older buildings which can be harder to retrofit for wheelchair accessibility, she said. “I recall interviewing a rural doctor several years ago who said that he knew his patients well and when a patient visits with mobility problems, he goes down and carries the patient up the steps to his office. My response was that is not respectful of the patient or safe for the patient or you. That doctor has since changed the location of his practice,” said Dr. Iezzoni.
Some doctors may resist paying for accessible medical equipment because of cost, but she said the benefits are worth it. These include preventing staff injuries when they transfer patients and being used by patients with temporary disabilities and aging people with bad knees, backs, hearing and sight. In addition, businesses may be eligible for federal and state tax credits.
Dr. Iezzoni recently visited her doctor where they finally got height-adjustable exam tables. “I asked the assistant, who really likes these tables? She said it’s the elderly ladies of short stature – the table is lowered and they sit down and get on it.”
But, Dr. Iezonni’s main message to doctors is that patients with disabilities deserve equal quality of care. “Just because we have a disability doesn’t mean we should get worse care than other people. It’s a matter of professionalism that doctors should want to give the same quality care to all their patients.”

Newly approved drug improves sleep onset in insomnia
In the first of two studies, a 50-mg dose of daridorexant was associated with a reduction in latency to persistent sleep (LPS) of 11.7 minutes at month 3 versus placebo. The drug also was associated with improved daytime function.
Based on these results, the Food and Drug Administration approved daridorexant for the treatment of insomnia in adults earlier in January.
“The study shows that it is a really good drug that works differently from most other drugs,” said Emmanuel Mignot, MD, PhD, professor of sleep medicine at Stanford (Calif.) University. “It’s more specific to sleep,” Dr. Mignot added.
The findings were published in the February issue of The Lancet Neurology.
Two trials, three doses
Daridorexant is a dual orexin receptor antagonist intended to reduce excessive wakefulness. The investigators hypothesized that, because of its therapeutic target, the drug would not cause sleepiness on the morning after administration.
To examine daridorexant’s safety and efficacy, the researchers conducted two double-blind, parallel-group, phase 3 trials. Eligible participants were aged 18 years or older, had moderate to severe insomnia disorder, and had a self-reported history of disturbed sleep at least 3 nights per week for at least 3 months before screening.
In study 1, investigators randomly assigned participants in groups of equal size to daridorexant 25 mg, 50 mg, or placebo. In study 2, participants were randomly assigned to daridorexant 10 mg, 25 mg, or placebo.
During a placebo run-in period, participants underwent polysomnography on two consecutive nights to define baseline values. At the end of months 1 and 3 of the treatment period, participants again underwent 2 nights of polysomnography. A final night of polysomnography occurred during the placebo run-out period.
Self-assessments included the Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ). This questionnaire, to which participants responded daily, is designed to measure the daytime impairments related to insomnia. The IDSIQ questions focus on sleepiness, mood, alertness, and cognition.
The study’s primary endpoints were change from baseline in wake after sleep onset (WASO) and LPS at months 1 and 3. Secondary endpoints were change from baseline in self-reported total sleep time and change in the IDSIQ sleepiness domain score at months 1 and 3.
The investigators enrolled 930 participants in study 1 and 924 in study 2. In each study, more than two-thirds of participants were women, 39% were aged 65 or older, and demographic and baseline characteristics were similar between treatment groups.
Dose-dependent effects
At month 1 in study 1, WASO was reduced by 22.8 minutes (P < .0001) in patients who received the 50-mg dose and by 12.2 minutes (P < .0001) in the 25-mg dose. At month 3, WASO was reduced by 18.3 minutes (P < .0001) in those assigned to 50 mg and by 11.9 minutes (P < .0001) in those assigned to 25 mg.
LPS was reduced by 11.4 minutes (P < .0001) at month 1 and by 11.7 minutes (P < .0001) at month 3 with the 50-mg dose versus placebo. LPS was reduced by 8.3 minutes (P = .0005) at month 1 and by 7.6 minutes (P = .0015) at month 3 with the 25-mg dose versus placebo.
At both time points, self-reported total sleep time was significantly increased and the IDSIQ sleepiness score significantly improved with the 50-mg dose. The 25-mg dose was associated with significant improvements in self-reported total sleep time at both time points, but not with significant improvements in IDSIQ sleepiness score.
In study 2, the 25-mg dose was associated with significant reductions in WASO at month 1 (11.6 minutes, P = .0001) and month 3 (10.3 minutes, P = .0028) compared with placebo. The 25-mg dose was not associated with significant differences in LPS at either time point, however.
Similarly, the 25-mg dose was associated with improvements in self-reported total sleep time, but not with the IDSIQ sleepiness score. The 10-mg dose was not associated with improvements on any endpoint compared with placebo.
Longer studies needed
In an accompanying editorial, Kai Spiegelhalder, PhD, University of Freiburg, Germany, and colleagues pointed out that although insomnia disorder is defined by self-reported difficulty initiating or maintaining sleep, none of the primary or secondary endpoints in these trials addressed these symptoms.
However, Dr. Mignot noted the use of the IDSIQ scale is the most interesting aspect of the study. Although difficulty with concentration and mood impairment are major symptoms of insomnia, they are often neglected. “This drug was reversing the daytime impairment that insomniacs have,” said Dr. Mignot. “We now need to systematically study people not only for the effect on sleep, but also that it makes them feel better the day after.”
He added that most of the current hypnotics were not developed to treat insomnia. Daridorexant, in contrast, targets the wake-promoting orexin system. “It works more selectively on sleep and not on other things. Most of the other sleeping pills have more complex effects on the brain,” Dr. Mignot said.
Commenting on the study, John Winkelman, MD, PhD, professor of psychiatry at Harvard Medical School, Boston, said the low prevalence of side effects associated with daridorexant was remarkable. “This is not what most of the benzodiazepine receptor agonists looked like,” said Dr. Winkelman, who was not involved with the research.
Many insomnia drugs affect transmitter systems that are widespread in the brain, thus provoking side effects. But orexin-receptor antagonists “don’t seem to produce a lot of side effects,” he noted.
Although the study duration was reasonable, longer studies will be necessary, he added. “And it would be nice to see comparative data. Prescribers want to see some context.” said Dr. Winkelman.

In the first of two studies, a 50-mg dose of daridorexant was associated with a reduction in latency to persistent sleep (LPS) of 11.7 minutes at month 3 versus placebo. The drug also was associated with improved daytime function.
Based on these results, the Food and Drug Administration approved daridorexant for the treatment of insomnia in adults earlier in January.
“The study shows that it is a really good drug that works differently from most other drugs,” said Emmanuel Mignot, MD, PhD, professor of sleep medicine at Stanford (Calif.) University. “It’s more specific to sleep,” Dr. Mignot added.
The findings were published in the February issue of The Lancet Neurology.
Two trials, three doses
Daridorexant is a dual orexin receptor antagonist intended to reduce excessive wakefulness. The investigators hypothesized that, because of its therapeutic target, the drug would not cause sleepiness on the morning after administration.
To examine daridorexant’s safety and efficacy, the researchers conducted two double-blind, parallel-group, phase 3 trials. Eligible participants were aged 18 years or older, had moderate to severe insomnia disorder, and had a self-reported history of disturbed sleep at least 3 nights per week for at least 3 months before screening.
In study 1, investigators randomly assigned participants in groups of equal size to daridorexant 25 mg, 50 mg, or placebo. In study 2, participants were randomly assigned to daridorexant 10 mg, 25 mg, or placebo.
During a placebo run-in period, participants underwent polysomnography on two consecutive nights to define baseline values. At the end of months 1 and 3 of the treatment period, participants again underwent 2 nights of polysomnography. A final night of polysomnography occurred during the placebo run-out period.
Self-assessments included the Insomnia Daytime Symptoms and Impacts Questionnaire (IDSIQ). This questionnaire, to which participants responded daily, is designed to measure the daytime impairments related to insomnia. The IDSIQ questions focus on sleepiness, mood, alertness, and cognition.
The study’s primary endpoints were change from baseline in wake after sleep onset (WASO) and LPS at months 1 and 3. Secondary endpoints were change from baseline in self-reported total sleep time and change in the IDSIQ sleepiness domain score at months 1 and 3.
The investigators enrolled 930 participants in study 1 and 924 in study 2. In each study, more than two-thirds of participants were women, 39% were aged 65 or older, and demographic and baseline characteristics were similar between treatment groups.
Dose-dependent effects
At month 1 in study 1, WASO was reduced by 22.8 minutes (P < .0001) in patients who received the 50-mg dose and by 12.2 minutes (P < .0001) in the 25-mg dose. At month 3, WASO was reduced by 18.3 minutes (P < .0001) in those assigned to 50 mg and by 11.9 minutes (P < .0001) in those assigned to 25 mg.
LPS was reduced by 11.4 minutes (P < .0001) at month 1 and by 11.7 minutes (P < .0001) at month 3 with the 50-mg dose versus placebo. LPS was reduced by 8.3 minutes (P = .0005) at month 1 and by 7.6 minutes (P = .0015) at month 3 with the 25-mg dose versus placebo.
At both time points, self-reported total sleep time was significantly increased and the IDSIQ sleepiness score significantly improved with the 50-mg dose. The 25-mg dose was associated with significant improvements in self-reported total sleep time at both time points, but not with significant improvements in IDSIQ sleepiness score.
In study 2, the 25-mg dose was associated with significant reductions in WASO at month 1 (11.6 minutes, P = .0001) and month 3 (10.3 minutes, P = .0028) compared with placebo. The 25-mg dose was not associated with significant differences in LPS at either time point, however.
Similarly, the 25-mg dose was associated with improvements in self-reported total sleep time, but not with the IDSIQ sleepiness score. The 10-mg dose was not associated with improvements on any endpoint compared with placebo.
Longer studies needed
In an accompanying editorial, Kai Spiegelhalder, PhD, University of Freiburg, Germany, and colleagues pointed out that although insomnia disorder is defined by self-reported difficulty initiating or maintaining sleep, none of the primary or secondary endpoints in these trials addressed these symptoms.
However, Dr. Mignot noted the use of the IDSIQ scale is the most interesting aspect of the study. Although difficulty with concentration and mood impairment are major symptoms of insomnia, they are often neglected. “This drug was reversing the daytime impairment that insomniacs have,” said Dr. Mignot. “We now need to systematically study people not only for the effect on sleep, but also that it makes them feel better the day after.”

FROM THE LANCET NEUROLOGY
Omicron subvariant 1.5 times more contagious than Omicron
The Statens Serum Institut, which monitors infectious diseases in Denmark, said that BA.2 is more contagious, but it doesn’t appear to increase hospitalizations or reduce how well the vaccine works.
BA.2 overtook BA.1 as the primary variant in Denmark within a few weeks, Troels Lillebaek, director of the institute, told CNBC. The subvariant has five unique mutations on a key part of the spike protein, which is what the coronavirus uses to invade human cells. This often means a higher rate of spreading.
The Omicron subvariant has been detected in at least 29 states in the United States and 56 countries, according to the latest update from Outbreak.info. The United States has detected 188 infections, with the worldwide total nearing 25,000.
Denmark has reported the highest number of cases, followed by the United Kingdom and India. Both Denmark and India have reported that BA.2 now accounts for about half of new COVID-19 cases in those countries.
On Jan. 28, the U.K. Health Security Agency said BA.2 has a “substantial” growth advantage over the original Omicron strain. The subvariant has spread faster in all regions of England where there were enough cases to conduct an analysis, the agency said in a report.
A preliminary evaluation found that BA.2 doesn’t appear to change how well the vaccine works compared to the original Omicron strain, the agency said. A booster dose was 70% effective at preventing symptomatic illness for BA.2, compared with 63% for the original Omicron strain.
The Centers for Disease Control and Prevention also said on Jan. 28 that, although the subvariant has become more common in some countries, it is currently at a low level in the United States and doesn’t appear to be more serious.
“Currently there is no evidence that the BA.2 lineage is more severe than the BA.1 lineage,” Kristen Nordlund, a CDC spokesperson, told CNBC.
The World Health Organization hasn’t labeled BA.2 a “variant of concern” so far but will continue to monitor it. WHO officials have said that new variants will arise as Omicron spreads across the world.
“The next variant of concern will be more fit, and what we mean by that is it will be more transmissible because it will have to overtake what is currently circulating,” Maria Van Kerkhove, the WHO’s COVID-19 technical lead, said during a livestream on Jan. 25.
“The big question is whether or not future variants will be more or less severe,” she said.

When the wrong history repeats itself
Fifteen years ago, Mrs. Smith was hospitalized for a dural sinus thrombosis.
This is a scary enough diagnosis as it is, but with the miracle of modern medicine she did great. She still checks in with me every year or so, but hasn’t had any recurrence.
Three years ago she tripped over her dog (amazing how often that seems to happen) and broke her arm. She landed in the hospital and needed orthopedic surgery, so they consulted me about the safety of getting her off the antiplatelet agent she was taking since stopping Coumadin.
When I arrived someone had already written an admitting note, which included a past history of “subdural hematoma, maintained on daily aspirin.”
Where this error came from, I don’t know. When I asked Mrs. Smith, she was quite clear on her correct diagnosis, and said she’d given it to the person who admitted her. So I dictated a consult, and typed it into my progress note each day. My notes made it clear that she’d had a dural sinus thrombosis and not a subdural hematoma.
This isn’t just nitpicking, obviously. They’re entirely different disorders. While the point may not be critical to her needing wrist surgery, these are medical records, and for this, and future hospital stays and for physicians to be aware of.
I signed off after a few days and didn’t think much of it until I was faxed a copy of her discharge summary. Which listed “subdural hematoma, maintained on daily aspirin.”
Apparently no one read my notes. Not that I’m really surprised.
We’re now 3 years later. As do many patients of her age, Mrs. Smith has landed in the hospital a few times since then. COVID, syncope, another fall. In each one of them the “subdural hematoma, maintained on daily aspirin” shows up.
At the most recent incident, the hospital’s neurologist called and asked me why I was treating a subdural hematoma with aspirin, then said Mrs. Smith had told him it was a dural sinus thrombosis. I said she was right, and he said “that makes more sense” and that he’d put it in his note.
He did, but it didn’t change anything. The discharge summary still listed “subdural hematoma, maintained on daily aspirin.”
At some point resistance is futile.
The stupidity of the whole thing is frustrating, as is knowing that it’s not just Mrs. Smith. The same scenario of incorrect history and medications is propagated from visit to visit. Taking a history is too time consuming for some. It’s easier to just read off, or cut and paste, a previous note. In cases where the patient can’t give a history I understand this. But when they can it’s just being too rushed – or lazy – to care.
It’s easy to blame EMRs as the culprits. Bashing them is fashionable. But in this case I can’t. They make it easier, but it’s nothing new. I remember a night almost 30 years ago when I was doing an admission at the Phoenix VA. When I picked up the most recent volume of the patient’s old chart to look at labs, the previous H&P said “see old chart.”
The problem is human nature. Not the computer.
But in this field the fallout can be serious – the wrong precautions taken, or medication given, based on a nonexistent contraindication. In medicine the stakes are high. Our decisions are only as good as the information we base them on, and if that information is wrong ...
Shortcuts have consequences.

Ischemic stroke rates higher in young women than young men
Young women appear to be at a higher risk of ischemic stroke than young men, according to a new systematic review of studies on this topic.
The review included 19 studies that reported on sex-specific stroke incidence among young adults and found that overall, in young adults aged 18-35 years, there were 44% more women with ischemic strokes than men.
This gap narrowed in the age group 35-45 years, for which there was conflicting evidence whether more men or women have ischemic strokes.
“An assertion that young women may be disproportionately at risk of ischemic stroke represents a significant departure from our current scientific understanding and may have important implications about the etiology of ischemic strokes in young adults,” the authors note.
“One of the take-home messages from this study is that stroke happens across the entire age spectrum, including young adults, even if they do not have traditional risk factors,” study coauthor Sharon N. Poisson, MD, associate professor of neurology at the University of Colorado Anschutz Medical Campus, Denver, told this news organization.
“If a young person presents with focal neurological symptoms, the possibility of a stroke should not be discounted just because they may not fit the typical profile of a stroke patient. We need more education of the population that young people – including young women – can have a stroke and that fast action to call emergency services is critical,” she said.
The study was published online Jan. 24 in the journal Stroke as part of a special “Go Red for Women” spotlight issue.
The researchers note that historically it has been believed that men have a higher incidence of stroke in every age group until very old age. However, recent evidence focused on the young adult age group has reported that there are more young women (ages 18-45) with ischemic strokes compared with young men, suggesting that young women may be disproportionately at risk compared with their male counterparts.
Pointing out that a better understanding of these sex differences is important in implementing strategies that can more effectively prevent and treat strokes in this age group, the researchers conducted the current review to synthesize the updated evidence.
They searched PubMed from January 2008 to July 2021 for relevant studies that were population-based and reported stroke incidence by sex or sex-specific incidence rate ratios of young adults age 45 and younger. Statistical synthesis was performed to estimate sex difference by age group (less than or equal to 35, 35-45 and less than or equal to 45 years) and stroke type.
They found 19 relevant studies, including three that reported on overlapping data, with a total of 69,793 young adults (33,775 women and 36,018 men).
Nine studies did not show a statistically significant sex difference among young adults less than or equal to 45 years. Three studies found higher rates of ischemic stroke among men among young adults less than or equal to 30 to 35 years. Four studies showed more women with ischemic strokes among young adults less than or equal to 35 years.
Overall, there was an effect of a significantly higher incidence of ischemic stroke in women younger than age 35 years, with an incidence rate ratio (IRR) of 1.44. In the 35- to 45-year age group, there was a nonsignificant sex difference in the rate of ischemic stroke, with a slight trend toward a higher incidence in women (IRR, 1.08).
“In this study the sex difference was not clear in the 35-45 age group. But in the age group of over 45 years we know that men have a higher risk of stroke than women, which is probably related to a higher level of atherosclerotic risk factors,” Dr. Poisson commented.
“Interpreting data on stroke in young people is challenging, as stroke is not so common in this population,” she said. “Combining multiple studies helps, but this also introduces a lot of variability, so we need to interpret these results with some caution. However, this is certainly intriguing data and suggests that something interesting may be going on in young adults,” she added. “These observations give us an initial clue that we need to look further into this issue.”
The study did not look at the possible mechanisms behind the results, as the current data came from administrative datasets that are limited in terms of the information collected.
But Dr. Poisson noted that the traditional risk factors for stroke are high blood pressure and the usual atherosclerotic factors such as high cholesterol.
“These are normally more common in men than in women, and myocardial infarction is more common in younger men than in younger women. But the observation that young women may have a higher risk of stroke than young men suggests that something different may be going on in the mechanism for stroke.”
She pointed out that women have some unique risk factors for stroke, including oral contraceptive use, pregnancy, and the postpartum period, particularly pre-eclampsia during pregnancy. In addition, migraine, especially migraine with aura, is associated with an increased stroke risk, and migraine is more common in young women than in young men.
“We don’t completely understand the role of these risk factors, but they may contribute to the results that we found,” Dr. Poisson commented. “The role of estrogen in stroke is complicated. While estrogen is generally thought to be protective against atherosclerotic risk factors, it also increases risk of clotting, so high estrogen states like pregnancy increase risk of stroke,” she added.
To better understand what is happening, prospectively collected clinical data on younger patients who have had a stroke are needed. Some such studies are underway, but a concerted effort to do this in a large, multicenter registry would be desirable, Dr. Poisson said.
She noted that the presentation of a stroke in young people would be similar to that in the older population, with the most recent acronym to help recognize stroke symptoms being “BE FAST” – balance, eyes (vision), face (drooping), arm, speech (slurred), time (call emergency services quickly).
Call for more women in clinical trials
In an accompanying commentary, Cheryl Bushnell, MD, professor of neurology at Wake Forest School of Medicine, Winston-Salem, N.C., and Moira Kapral, MD, professor in medicine and health policy at the University of Toronto, say these findings support the need for further study to understand and address the causes and risk factors of stroke in young women.
However, they point out that representation and reporting of women in clinical trials of acute stroke continues to be suboptimal, and they call for improved incorporation of sex and gender into study design, analysis, and interpretation, which they say is critical for producing research that is broadly generalizable and applicable to different populations.

Young women appear to be at a higher risk of ischemic stroke than young men, according to a new systematic review of studies on this topic.
The review included 19 studies that reported on sex-specific stroke incidence among young adults and found that overall, in young adults aged 18-35 years, there were 44% more women with ischemic strokes than men.
This gap narrowed in the age group 35-45 years, for which there was conflicting evidence whether more men or women have ischemic strokes.
“An assertion that young women may be disproportionately at risk of ischemic stroke represents a significant departure from our current scientific understanding and may have important implications about the etiology of ischemic strokes in young adults,” the authors note.
“One of the take-home messages from this study is that stroke happens across the entire age spectrum, including young adults, even if they do not have traditional risk factors,” study coauthor Sharon N. Poisson, MD, associate professor of neurology at the University of Colorado Anschutz Medical Campus, Denver, told this news organization.
“If a young person presents with focal neurological symptoms, the possibility of a stroke should not be discounted just because they may not fit the typical profile of a stroke patient. We need more education of the population that young people – including young women – can have a stroke and that fast action to call emergency services is critical,” she said.
The study was published online Jan. 24 in the journal Stroke as part of a special “Go Red for Women” spotlight issue.

FDA grants full approval to Moderna COVID-19 vaccine
Moderna announced today that its mRNA COVID-19 vaccine has received full Food and Drug Administration approval for adults 18 years and older.
The move lifts an FDA emergency use authorization for the vaccine, which started Dec. 18, 2020.
The Moderna vaccine also now has a new trade name: Spikevax.
The FDA approval comes a little more than 5 months after the agency granted full approval to the Pfizer/BioNTech COVID-19 vaccine on Aug. 23. At the time, the Pfizer vaccine received the trade name Comirnaty.
The FDA approved the Moderna vaccine based on how well it works and its safety for 6 months after a second dose, including follow-up data from a phase 3 study, Moderna announced this morning through a news release. The FDA also announced the news.
Spikevax is the first Moderna product to be fully licensed in the United States.
The United States joins more than 70 other countries where regulators have approved the vaccine. A total of 807 million doses of Moderna’s COVID-19 vaccine were shipped worldwide in 2021, the company reported.
“The full licensure of Spikevax in the U.S. now joins that in Canada, Japan, the European Union, the U.K., Israel, and other countries, where the adolescent indication is also approved,” Stéphane Bancel, Moderna chief executive officer, said in the release.

Billionaire Mark Cuban launches online pharmacy for generics
The Mark Cuban Cost Plus Drugs Company (MCCPDC) plans to offer the leukemia therapy imatinib for $47 per month, for example, compared with $120 or more with a common voucher and a retail price of $9,657 per month.
Other examples of lower-priced generics include the ulcerative colitis treatment mesalamine, which goes for $32.40 per month on the new online pharmacy versus $940 per month retail. In addition, the MCCPDC will offer the gout treatment colchicine at a lower price, charging $8.70, compared with $182 per month retail.
Likely in part because of claims of significant cost savings and in part because of Mr. Cuban’s celebrity status, the new venture is getting widespread media attention. Forbes, NPR, and TMZ have shared the news since the new digital pharmacy was announced earlier this month.
The new venture plans to charge consumers 15% above the manufacturing cost for the generic medications, plus a $3 fee for pharmacists and $5 for shipping. People will still require a prescription from their doctor to get the medications.
Generic pricing and social benefit
The top 100 generic products account for about half of generic sales, and there is enough competition for these high-demand medications that “the prices have come down close to zero,” said William Comanor, PhD, a health economist and professor of health policy and management at the University of California, Los Angeles. The remaining generic agents have lower-volume demand.
One prominent example is Daraprim, a decades-old treatment for the life-threatening parasitic infection toxoplasmosis. The drug jumped into the spotlight in 2015 when Martin Shkreli and his company Vyera Pharmaceuticals bought the rights to make the generic drug and raised the price overnight from $13.50 to $750. In January 2022, a U.S. judge banned Mr. Shkreli from the pharmaceutical industry and ordered him to pay an almost $65 million fine.
Dr. Comanor agreed the price should have been raised – $13.50 “was not economically viable” – but not as steep as $750.
“Say Mark Cuban says he will cut the price from $750 to $300. He will still make money. There is a market for these low-volume products,” he said. “There would also be a social benefit.”
A direct-to-consumer digital pharmacy
MCCPDC is “cutting out the middleman” in two ways. The business model calls for charging consumers out of pocket, so insurance companies are not involved. Also, the company created its own pharmacy business manager firm in October 2021, allowing it to negotiate prices with drugmakers in house.
The company also announced plans to complete construction of a 22,000-square-foot pharmaceutical factory in Dallas by the end of 2022.
Reactions on social media ranged from celebratory to people disappointed their generic medication would not cost significantly less or is not provided by the digital pharmacy.
When weighted by the number of prescriptions, prices for generics have declined in the United States.
“Overall, U.S. generic prices are the lowest in the world,” Dr. Comanor said. “People say U.S. drug prices are the highest in the world. That’s true for branded, but it’s not true for generics.
“So if someone asks if U.S. drug prices are the highest or lowest in the world, the answer is both,” he said.
“Maybe there is a role to play for this new pharmacy,” Dr. Comanor said when asked if the initiative seems like a positive development.
The state of California also announced plans to provide its own generic drugs, he said.
“But you won’t see a lot of entrepreneurs getting into this because the volumes are so low. If Cuban called me, I would tell him to provide Daraprim and similar, low-volume products,” Dr. Comanor said of the billionaire. “He’s a rich guy; maybe he can do it.”

Yoga maneuver may prevent vasovagal syncope
The tadasana exercise – a movement-based contemplative practice that gradually corrects orthostatic imbalance by strengthening protective neuromuscular reflexes – practiced for just 15 minutes twice a day, was associated with the complete elimination of episodes of vasovagal syncope for many patients.
“These exercises are very easy to perform, inexpensive, and very effective. This is a very easy fix for a scary and potentially dangerous condition,” lead author Hygriv Rao, MD, said in an interview. “We are excited about these results. We thought it would work, but we did not expect it to be so effective. It seems to work for almost all patients.
“We found that, with the tadasana maneuver, episodes of full syncope, where the patient actually loses consciousness, ceased completely, and episodes of near-syncope, where the patient feels faint but does not completely pass out, were greatly reduced,” Dr. Rao added. “The actual loss of consciousness, which is the most dangerous part, is practically gone. This gives a lot of confidence to patients and their families.”
The researchers reported their initial results from a pilot study of the technique in a letter to JACC: Clinical Electrophysiology that was published online Jan. 26, 2022.
Dr. Rao, a cardiologist at the KIMS Hospitals, Hyderabad, India, explained that vasovagal syncope is a brief loss of consciousness caused by a neurologically induced drop in blood pressure caused by faulty neuromuscular reflexes.
It is typically triggered by emotional stress, prolonged standing, or getting up from a sitting position too quickly.
Very few treatments have been shown effective, with current management approaches involving avoiding triggers, increasing fluids, and if the individual feels an episode coming on, they can take steps to stop it by lying down, raising their legs, or lowering their head to increase blood flow to the brain.
“Recently, there has been a lot of interest in yoga as a preventative therapy for vasovagal syncope,” Dr. Rao noted. “We considered various yoga positions and we chose the tadasana maneuver to study in this context as it resembles exercises sometimes given to patients with vasovagal syncope but with some differences including the addition of synchronized breathing, which may help stabilize autonomic tone.”
For the tadasana maneuver, the individual stands straight with their feet together, arms by their side (against a wall if they need support), and alternatively lift the front and back part of their feet.
They first lift their toes with their weight resting on the ball of their feet, then after a few seconds they raise their heels with their weight on the front of the foot. Then after a few more seconds they lift their arms over their shoulders, stretching upward while standing on their toes.
These movements are synchronized with breathing exercises, with the individual taking a deep breath in as they lift their arms and breathing out again on lowering the arms.
“Each movement takes a few seconds, and each cycle of movements takes about 2 minutes. If this is performed 8 times, then this would take about 15 minutes. We recommend this 15-minute routine twice a day,” Dr. Rao said.
For the current study, 113 patients diagnosed with recurrent vasovagal disorder were counseled to practice standard physical maneuvers and maintain adequate hydration. Medications were prescribed at the discretion of the treating physician.
Of these, 61 patients were additionally trained to practice the tadasana maneuver and asked to practice the movement for 15 minutes twice a day. The mean durations of symptoms and follow-up in the two groups were similar. The average follow-up was about 20 months.
Results showed that episodes of both near-syncope and syncope decreased in both groups but there was a much larger reduction in the patients practicing the tadasana maneuver.
Before treatment, the 52 patients in the conventional group experienced 163 syncope or near-syncope events. At follow-up, 22 symptom recurrences occurred in 12 patients (23%). Total mean events per patient declined from 3 to 0.4.
Full syncope events in this group declined from 65 in 32 patients to 2 in 2 patients (mean per patient, 1.3 to 1), and near-syncope events fell from 98 in 34 patients to 20 in 10 patients (mean per patient, 2.0 to 0.4).
In the tadasana group, 61 patients had 378 syncope/near-syncope events before treatment; at follow-up, only 6 events occurred in 5 patients (8%). Per patient, total events declined from a mean of 6 to 0.1.
Full syncope events fell from 108 in 48 patients to 0 (mean per patient, 1.8 to 0), and near-syncope events declined from 269 in 33 patients to 6 in 5 patients (mean per patient, 4.4 to 0.1).
“This combination of exercise and breathing influences the neuromuscular reflex malfunction that occurs in vasovagal syncope,” Dr. Rao noted. “The movements focus on strengthening neuromuscular reflexes in the quadriceps and the calf muscles, which can increase the blood circulation and venous return, thus preventing blood pooling in the lower body.”
The researchers said this pilot study offers three main findings. First, both conventional therapy and conventional plus tadasana therapy appeared to benefit patients, compared with their respective baseline symptom burden. Second, application of tadasana as an adjunctive treatment was associated with fewer total event recurrences (that is, syncope and near-syncope combined), and third, tadasana was well tolerated, with no adverse events reported.
“The reduction in total events (i.e., syncope and near-syncope events), compared with pretreatment numbers, was substantial and most tadasana patients were managed without any pharmacotherapy,” the authors reported.
Dr. Rao noted that at baseline almost all patients in both groups were taking medications for the condition, but during the study these medications were reduced as fewer episodes occurred. At the end of the follow-up, 80% of the conventional group were still taking medication, compared with just 14% of those in the tadasana group.
Patients had an initial training session in person with a yoga instructor and then received follow-on training by video online. Dr. Rao said there was a very high rate of compliance, “almost 100%.”
He reports that a total of 200 patients have now been treated with this approach at his hospital with very similar results to those seen in the initial study.
This work was supported in part by a grant from the Dr Earl E. Bakken Family in support of heart-brain research. Dr. Rao disclosed no relevant financial relationships.

The tadasana exercise – a movement-based contemplative practice that gradually corrects orthostatic imbalance by strengthening protective neuromuscular reflexes – practiced for just 15 minutes twice a day, was associated with the complete elimination of episodes of vasovagal syncope for many patients.
