Chronic constipation linked to cognitive decline
Compared with individuals who have a bowel movement once daily, adults with constipation who have a bowel movement every 3 days or more had significantly worse cognition that was commensurate with an additional 3 years of chronological cognitive aging, the investigators found.
“We should watch for symptoms of abnormal intestinal function, especially constipation, in older individuals, as these symptoms may hint at a higher risk of cognitive decline in the future,” study investigator Chaoran Ma, MD, PhD, former research fellow at Brigham and Women’s Hospital and Harvard Medical School, both in Boston, and current assistant professor at the University of Massachusetts Amherst, said in an interview.
The findings were presented at the Alzheimer’s Association International Conference.
Prevent constipation, improve brain health?
It’s estimated that 16% of the world’s population suffers from constipation. The problem is more common in older adults, owing to age-related factors such as a lack of dietary fiber and exercise and the use of constipating drugs to treat other medical conditions.
Chronic constipation – defined as having bowel movements every 3 days or more – has been associated with long-term health problems, such as inflammation, hormonal imbalances, anxiety, and depression.
However, few studies have investigated variations in intestinal motility and cognitive function.
“Our study provides first-of-its-kind evidence that examined a wide spectrum of bowel movement frequency, especially an analysis of the more frequent end, in relation to cognitive function,” Dr. Ma said.
The analysis involved data from 112,753 women and men from the Nurses’ Health Study (aged 30-55 years), the Nurses’ Health Study II (aged 25-42), and the Health Professionals Follow-up Study (aged 40-75).
Data on participants’ bowel movement frequency was collected between 2012 and 2013, and self-assessments of cognitive function were obtained from 2014 to 2017. A subgroup of 12,696 participants completed a standard neuropsychological test battery for objective cognitive assessment between 2014 and 2018.
The results show that bowel movement frequency was associated with overall objective cognitive function and learning and working memory in an inverse J-shape dose-response manner (both P for nonlinearity < .05).
Compared with adults who had one bowel movement daily, those who only had a bowel movement every 3 or more days had significantly worse cognition, equivalent to 3 years of additional aging (95% confidence interval, 1.2-4.7).
The researchers also observed similar J-shape dose-response relationships of bowel movement frequency with the odds of subjective cognitive decline and the likelihood of having more subjective cognitive complaints over time.
Compared with once-daily bowel movements, having bowel movements every 3 or more days was associated with a greater likelihood of subjective cognitive decline (odds ratio, 1.73; 95% CI, 1.60-1.86).
These relationships were generally consistent across the three cohorts and subgroups.
“These results stress the importance of clinicians discussing gut health, especially constipation, with their older patients,” senior investigator Dong Wang, MD, ScD, with Harvard Medical School and Brigham and Women’s Hospital, said in a conference statement.
“Interventions for preventing constipation and improving gut health include adopting healthy diets enriched with high-fiber and high-polyphenol foods such as fruits, vegetables, and whole grains; taking fiber supplementation; drinking plenty of water every day; and having regular physical activity,” Dr. Wang added.
The researchers also explored the role of the gut microbiome in the association between bowel movement frequency and cognitive function in a subgroup of 515 women and men.
They found that bowel movement frequency and subjective cognition were significantly associated with the overall variation of the gut microbiome (both P < .005) and specific microbial species.
“This research adds further evidence for a link between the microbiome and gastrointestinal function with cognitive function,” Dr. Ma said in an interview.
Interconnected systems
Commenting on the study in a conference statement, Heather M. Snyder, PhD, vice president of medical and scientific relations at the Alzheimer’s Association, noted that “our body systems are all interconnected. When one system is malfunctioning, it impacts other systems. When that dysfunction isn’t addressed, it can create a waterfall of consequences for the rest of the body.”
Dr. Snyder cautioned, however, that “there are a lot of unanswered questions about the connection between the health of our digestive system and our long-term cognitive function. Answering these questions may uncover novel therapeutic and risk-reduction approaches for Alzheimer’s and other dementias.”
In an interview, Percy Griffin, PhD, director of scientific engagement at the Alzheimer’s Association, noted that the U.S. Study to Protect Brain Health Through Lifestyle Intervention to Reduce Risk, is evaluating the impact of behavioral interventions on the gut-brain axis.
“We want to better understand how engaging in healthier habits can impact microorganisms in the gut and how changes in gut bacteria relate to brain health,” Dr. Griffin said.
The study was funded by the National Institutes of Health. Dr. Ma, Dr. Wang, Dr. Snyder, and Dr. Griffin have no relevant disclosures.

Opioid initiation in dementia tied to an 11-fold increased risk of death
Opioid initiation for older adults with dementia is linked to a significantly increased risk of death, especially in the first 2 weeks, when the risk is elevated 11-fold, new research shows.
“We expected that opioids would be associated with an increased risk of death, but we are surprised by the magnitude,” study investigator Christina Jensen-Dahm, MD, PhD, with the Danish Dementia Research Centre, Copenhagen University Hospital, Rigshospitalet, Denmark, told this news organization.
“It’s important that physicians carefully evaluate the risk and benefits if considering initiating an opioid, and this is particularly important in elderly with dementia,” Dr. Jensen-Dahm added.
The findings were presented at the Alzheimer’s Association International Conference.
Risky business
Using Danish nationwide registries, the researchers analyzed data on all 75,471 adults in Denmark who were aged 65 and older and had been diagnosed with dementia between 2008 and 2018. A total of 31,619 individuals (42%) filled a prescription for an opioid. These “exposed” individuals were matched to 63,235 unexposed individuals.
Among the exposed group, 10,474 (33%) died within 180 days after starting opioid therapy, compared with 3,980 (6.4%) in the unexposed group.
After adjusting for potential differences between groups, new use of an opioid was associated with a greater than fourfold excess mortality risk (adjusted hazard ratio, 4.16; 95% confidence interval, 4.00-4.33).
New use of a strong opioid – defined as morphine, oxycodone, ketobemidone, hydromorphone, pethidine, buprenorphine, and fentanyl – was associated with a greater than sixfold increase in mortality risk (aHR, 6.42; 95% CI, 6.08-6.79).
Among those who used fentanyl patches as their first opioid, 65% died within the first 180 days, compared with 6.7% in the unexposed – an eightfold increased mortality risk (aHR, 8.04; 95% CI, 7.01-9.22).
For all opioids, the risk was greatest in the first 14 days, with a nearly 11-fold increased risk of mortality (aHR, 10.8; 95% CI, 9.74-11.99). However, there remained a twofold increase in risk after taking opioids for 90 days (aHR, 2.32; 95% CI, 2.17-2.48).
“Opioids are associated with severe and well-known side effects, such as sedation, confusion, respiratory depression, falls, and in the most severe cases, death. In the general population, opioids have been associated with an increased risk of death, and similar to ours, greatest in the first 14 days,” said Dr. Jensen-Dahm.
Need to weigh risks, benefits
Commenting on the study, Percy Griffin, PhD, director of scientific engagement at the Alzheimer’s Association, told this news organization that the use of strong opioids has “increased considerably over the past decade among older people with dementia. Opioid therapy should only be considered for pain if the benefits are anticipated to outweigh the risks in individuals who are living with dementia.”
“Opioids are very powerful drugs, and while we need to see additional research in more diverse populations, these initial findings indicate they may put older adults with dementia at much higher risk of death,” Nicole Purcell, DO, neurologist and senior director of clinical practice at the Alzheimer’s Association, added in a conference statement.
“Pain should not go undiagnosed or untreated, in particular in people living with dementia, who may not be able to effectively articulate the location and severity of the pain,” Dr. Purcell added.
These new findings further emphasize the need for discussion between patient, family, and physician. Decisions about prescribing pain medication should be thought through carefully, and if used, there needs to be careful monitoring of the patient, said Dr. Purcell.
The study was supported by a grant from the Capital Region of Denmark. Dr. Jensen-Dahm, Dr. Griffin, and Dr. Purcell have no relevant disclosures.

Alzheimer’s disease and the primary care physician
Recent news highlights advancements in the understanding of Alzheimer’s disease: Increased information on biomarkers to be used for evaluation and diagnosis and recent studies on lifestyle factors or medications that do and do not correlate with Alzheimer’s disease.
It is helpful for family medicine physicians and other primary care physicians to be aware of this information to better help our patients and their families. When we have patients with strong family history of cognitive decline, they often will ask us for an early assessment or help with next steps and requests for treatment. Patients and their families want to understand what testing will be done by the neurologist they will likely be seeing.
An article published in Alzheimer’s and Dementia put forward a consensus statement by 11 European scientific societies on diagnosis and management of the disease. These societies defined work flows for processes to utilize biomarkers to diagnose Alzheimer’s disease. Although these work flows may help with diagnosis, they are not able to definitively rule out other causes of dementia. However, they may lead to consistency in how treatments are determined.1 More consistency will be helpful in counseling patients and their families on the next steps in the treatment plan.
Another study evaluated the correlation between lean mass and dementia. This study demonstrated a decreased risk of dementia in patients with higher lean mass. It is unclear from this study whether the higher lean mass is protective or if decreased cognitive function decreases the amount of lean mass. However, this study does provide hope in two possible ways: it provides potentially predictive information on who may be more at risk of declining cognitive function as well as a modifiable risk factor to address.2 Family physicians may use this as part of their counseling for patients who are concerned about their potential risk of dementia. It is yet another reason why we may counsel on healthy diet and weight-bearing exercise to help maintain lean mass.
Other associations related to dementia have been disproven. An article in Gastroenterology discussed the association between cognitive decline and use of proton pump inhibitors and H2 blockers – indicating that there is no association.3 Although there are reasons why we want to limit the use of these medications – particularly when they are not needed, it is a relief that they are not causing cognitive decline in patients.
Most of these studies provide information that is helpful for both family medicine physicians and patients. We are learning more about cognitive decline and Alzheimer’s disease. This gives hope to patients with strong family history that we may be able to reduce their risks. These studies also give us possible risk factors on which we can counsel our patients.
Developments in Alzheimer’s disease research are speeding ahead and give family physicians a bit more information to discuss with patients and their families as they face the challenging symptoms of cognitive decline. Future research, it is hoped, will help with treatment plans and modifiable risk factors to improve the outcomes for patients at high risk of cognitive decline.

Although these work flows may help with diagnosis, they are not able to definitively rule out other causes of dementia. However, they may lead to consistency in how treatments are determined.1 More consistency will be helpful in counseling patients and their families on the next steps in the treatment plan.
Another study evaluated the correlation between lean mass and dementia. This study demonstrated a decreased risk of dementia in patients with higher lean mass. It is unclear from this study whether the higher lean mass is protective or if decreased cognitive function decreases the amount of lean mass. However, this study does provide hope in two possible ways: it provides potentially predictive information on who may be more at risk of declining cognitive function as well as a modifiable risk factor to address.2 Family physicians may use this as part of their counseling for patients who are concerned about their potential risk of dementia. It is yet another reason why we may counsel on healthy diet and weight-bearing exercise to help maintain lean mass.
Other associations related to dementia have been disproven. An article in Gastroenterology discussed the association between cognitive decline and use of proton pump inhibitors and H2 blockers – indicating that there is no association.3 Although there are reasons why we want to limit the use of these medications – particularly when they are not needed, it is a relief that they are not causing cognitive decline in patients.
Most of these studies provide information that is helpful for both family medicine physicians and patients. We are learning more about cognitive decline and Alzheimer’s disease. This gives hope to patients with strong family history that we may be able to reduce their risks. These studies also give us possible risk factors on which we can counsel our patients.
Developments in Alzheimer’s disease research are speeding ahead and give family physicians a bit more information to discuss with patients and their families as they face the challenging symptoms of cognitive decline. Future research, it is hoped, will help with treatment plans and modifiable risk factors to improve the outcomes for patients at high risk of cognitive decline.

U.S. states, counties with highest Alzheimer’s prevalence rates identified
Investigators at Rush University in Chicago found AD prevalence was highest in Maryland, New York, Mississippi, and Florida. At the county level, Miami-Dade in Florida, Baltimore city, and Bronx County in New York were among the U.S. counties with the highest prevalence of the disease.
Such geographical variations may be caused by the unique make-up of regional populations, study investigator Kumar Rajan, PhD, professor of medicine and director of Rush Institute for Healthy Aging, Rush University Medical Center, Chicago, said in an interview.
Dr. Rajan presented the research at the Alzheimer’s Association International Conference.
High-impact research
An estimated 6.7 million Americans are living with AD, a figure that’s expected to double by 2050. Estimating the prevalence of Alzheimer’s across states’ counties can provide a better understanding of region-specific disease burden and have policy implications for resource allocation, Dr. Rajan noted.
To determine the state- and county-specific prevalence of AD, the researchers applied AD data from the Chicago Health and Aging Project, a population-based study that’s about 60% African American, to county- and state-level data from the National Center for Health Statistics.
“We used estimates in our study in Chicago, which began in the 1990s and has approximately 10,800 people, and projected those estimates to county-level populations to see what the variations look like,” said Dr. Rajan.
Of 3,142 counties in 50 states, the East and Southeastern regions of the United States had the highest AD prevalence. For states, the highest rates were in Maryland (12.9%), New York (12.7%), Mississippi (12.5%), and Florida (12.5%).
California and Illinois were also among the top 10 states with the highest prevalence of Alzheimer’s.
California had the highest number of residents, with 719,000 (95% confidence interval, 665,000-774,400), followed by Florida with 579,000 (95% CI, 539,900 to 620,000), and Texas with 459,000 (95% CI, 422,700 to 496,000).
The three counties with the highest prevalence, all with 16.6%, were Miami-Dade County, Baltimore city, and Bronx County.
One county in the top 10 for AD prevalence was El Paso, Tex., which Dr. Rajan found “a bit surprising,” as Texas was not among the top four states with the highest prevalence.
In addition to older age, what’s likely driving elevated AD prevalence in these areas is the substantially larger proportion of minority populations who are at higher risk for AD, possibly due to health disparities, said Dr. Rajan.
Determining local-level estimates of AD should have “a very high impact” on public health programs aimed at AD prevention, detection, and treatment, he said. In addition, as more AD drugs are approved, there will likely be county-level and even state-level implications for Medicare coverage.
In addition, these new findings could help physicians treating or caring for minority populations “understand the landscape of what the disease looks like,” said Dr. Rajan.
A limitation of the study was that it was based on data from a single study, he noted.
The next step is to expand this research. Dr. Rajan and others are establishing the Regional and Ethnic Variations in Alzheimer’s and Cognitive Health Consortium, with the goal of gaining a better understanding of AD prevalence across six U.S. regions.
Optimal resource distribution
In a comment, Percy Griffin, PhD, director of scientific engagement, Alzheimer’s Association, said the research provides useful information about AD prevalence at the local level.
“We need to understand how specific demographics and characteristics can help explain some of the high prevalence in certain areas.”
Compared with White Americans, Dr. Griffin noted that Black Americans are twice as likely to have AD, and older Hispanic Americans are 1.5 times as likely.
This new data will help pinpoint areas of high risk and high need so that funding, staffing, and other resources for those with AD and other dementias can be optimally distributed, he said.
“It gives us that kind of geographic specificity in terms of the prevalence so we can dig deeper and better allocate resources on a county level,” he added.
The Alzheimer’s Association “is fully committed to working with local agencies and being in the communities to assist them in their efforts to intervene in this disease.”
The study also highlights the need for more research to determine what factors other than age and race – such as potential environmental factors – might affect regional AD prevalence, he said.
The study received funding from the National Institutes of Health. Dr. Rajan and Dr. Griffin reported no relevant financial relationships.

More children missing developmental milestones: Survey
Nearly 9 out of every 100 U.S. children are now diagnosed with a developmental disability, according to updated figures from the CDC.
Developmental disabilities include autism, intellectual disabilities such as Down syndrome, and a range of other diagnoses related to missing developmental milestones in how a child plays, learns, or speaks.
The newly reported increase amounts to just over 1 percentage point from 2019 to 2021. In 2019, the rate of developmental disability diagnoses was about 7 in 100 children. The latest figures are from 2021 data, published this week after the CDC finished analyzing responses to the National Health Survey.
Among children ages 3-17 years old in 2021, the survey showed that:
- 1.7% had an intellectual disability.
- 3.1% had autism spectrum disorder.
- 6.1% had a diagnosis of “other developmental delay.”
No significant change was seen from 2019 to 2021 in how common it was for survey respondents to report children having autism or an intellectual disability. The overall increase was driven by a jump in reports from parents that a doctor or health professional told them their child had “any other developmental delay,” excluding autism spectrum disorder or an intellectual disability.
“A lot of times developmental delays might be temporary diagnoses that evolve into something like autism, potentially, or intellectual disability. But also a lot of times children do age out of those,” lead report author and CDC statistician Benjamin Zablotsky, PhD, told CBS News.
The CDC offers an app called Milestone Tracker to help parents watch for signs of developmental delays, in addition to operating a public health education program called “Learn the Signs. Act Early.”
The new report showed that boys were nearly twice as likely as girls to have any developmental delay, a pattern that was magnified when looking specifically at autism diagnoses. Boys were more than three times as likely as girls to be diagnosed with autism spectrum disorder. The rate of autism among boys was 4.7%, compared with 1.5% among girls.
While these latest survey results showed consistent rates of autism from 2019 to 2021, a different CDC report earlier this year showed an alarming jump in the rate of autism spectrum disorder among 8-year-olds. That report, which compared data from 2008 to 2020, showed the rate of autism among 8-year-olds rose during those 12 years from 1 in 88 kids to 1 in 36 kids.
The two analyses also differed in their findings regarding prevalence of autism when looking at children by race and ethnicity. The report from earlier this year showed that Black and Hispanic children were more likely to be diagnosed with autism, compared with White children. This latest report did not find any differences in the prevalence of autism based on a child’s race or ethnicity.

Global burden of brain disorders surpasses cardiovascular disease and cancer
– at huge cost to health care systems and society, an analysis of data from the most recent Global Burden of Disease (GBD) study shows.
“The burden of brain conditions will increase as populations continue to grow and age,” said study presenter Shayla Smith, MPH, an epidemiologist at the Institute for Health Metrics and Evaluation, the University of Washington, Seattle, in a press release.
“By 2050, more than 50 million people will be aged 65-79,” she explained, adding that the COVID-19 pandemic “has also influenced the prevalence of mental disorders globally, as people were forced to isolate and social networks broke down.”
Other factors related to brain disorders, she noted, include education level, obesity, and smoking.
“There’s still research to be done on what is the most effective way to maintain brain health, but some literature suggests a healthy brain can be achieved through a healthy lifestyle of managing conditions such as high blood pressure and diabetes, limiting alcohol consumption and smoking, prioritizing sleep, eating healthy, and staying physically and mentally active,” said Ms. Smith.
The findings were presented at the annual meeting of the Congress of the European Academy of Neurology.
An ‘ambitious exercise’
Coinvestigator Xaviera Steele, also from the IHME, told press conference attendees that the institute was established at the University of Washington in 2007 with the aim of “standardizing the measurement of health outcomes around the world and for all health conditions.”
A central part of that is the GBD study, “which is a very ambitious exercise in descriptive epidemiology in an effort to systematically quantify health loss” due to disease, injury, and risk factors over time, stratified by country, region, age, and sex. In addition, researchers are mapping and projecting trends over the next century and are estimating disease expenditure by country, by type of expense, and by condition “to derive a health care access and quality score for each health system in the world,” Ms. Steele said.
They are also estimating exposure to risk factors, how those risk factors contribute to health burden, and associated health outcomes by race and ethnicity to reflect the “disparities that we know are very prevalent in countries such as the United States.” From that work, Ms. Steele said that brain health and related conditions “do emerge as one of the more pressing challenges of the 21st century.”
Increase in dementia, mental health conditions
The data, which were gathered from 200,000 sources by the IHME, indicate that the number of individuals aged 65 years or older will increase by 350% by 2100. Ms. Steele underlined that “policy action will be needed to help families, who will struggle to provide high-quality care for their loved ones with dementia at a reasonable cost.”
The IHME calculates that in Europe health care spending on Alzheimer’s disease will increase by 226% between 2015 and 2040.
Turning to other conditions, Ms. Steele showed that since 1990, the number of individuals living with anxiety in the European region has increased by 14%, while the number living with depressive disorders has gone up by 13%.
Worldwide, the figures are even starker. Depression is estimated to affect 300 million people across the globe, which represents a 71% increase since 1990. The number of strokes increased by 95% over the same period.
Nevertheless, the “impact of brain conditions such as stroke has decreased since the 1990s due to improved treatments available,” Ms. Smith noted in the press release.
To estimate the toll caused by brain conditions, including neurologic disorders, mental disorders, cerebrovascular disease, brain cancer, brain injuries, and select infectious conditions, the researchers calculated disability-adjusted life years (DALYs).
This, Ms. Smith explained in her presentation, “captures the morbidity and mortality associated with brain conditions” and is adjusted for patient location, age, and sex.
The investigators found that, globally, brain conditions accounted for more than 15% of all health loss in 2021, at 406 DALYs – more than the 206 million DALYs that were associated with cancer, and the 402 million that were linked to cardiovascular disease.
This health loss is associated with a $1.22 trillion loss in income for people living with health disorders worldwide and accounts for $1.14 trillion in direct health care costs.
The burden of mental disorders, neurologic conditions, and stroke is expected to increase dramatically between now and 2050, said Ms. Smith, who noted that health loss linked to brain conditions is higher in younger patients. This will create “new challenges for health systems, employers, patients, and families,” she said in the press release.
“Our goal is to see an improved prevention and treatment landscape for other brain conditions and reverse the growing health loss that we are currently forecasting.”
Worrying increase in stroke
Jurgita Valaikiene, MD, PhD, center of neurology, clinic of neurology and neurosurgery, Vilnius (Lithuania) University Faculty of Medicine, who chaired the session, was taken aback by the findings, particularly by the worldwide increase in stroke cases.
“I work in stroke,” she said, and “we spend a lot of time on the diagnosis of stroke” and its prevention. “We try to be faster, to catch asymptomatic stenosis in the neck or head, and to apply the best medical treatment to avoid a stroke. But despite that, the numbers are increasing. I understand the population is getting older ... but still it’s a huge number.”
Dr. Valaikiene pointed out that stroke is not necessarily a condition of aging, insofar as increasing age “is not related directly to stenosis in the neck. “For example, we can have healthier vessels in older age and unhealthy vessels, with high-grade stenosis, in someone aged 30 or 40 years.”
“There are a lot of risk factors, such as smoking, physical activity, and so on. It depends on the individual,” she added.
The study was funded by the Institute for Health Metrics and Evaluation at the University of Washington. The authors have disclosed no relevant financial relationships.

The investigators found that, globally, brain conditions accounted for more than 15% of all health loss in 2021, at 406 DALYs – more than the 206 million DALYs that were associated with cancer, and the 402 million that were linked to cardiovascular disease.
This health loss is associated with a $1.22 trillion loss in income for people living with health disorders worldwide and accounts for $1.14 trillion in direct health care costs.
The burden of mental disorders, neurologic conditions, and stroke is expected to increase dramatically between now and 2050, said Ms. Smith, who noted that health loss linked to brain conditions is higher in younger patients. This will create “new challenges for health systems, employers, patients, and families,” she said in the press release.
“Our goal is to see an improved prevention and treatment landscape for other brain conditions and reverse the growing health loss that we are currently forecasting.”
Worrying increase in stroke
Jurgita Valaikiene, MD, PhD, center of neurology, clinic of neurology and neurosurgery, Vilnius (Lithuania) University Faculty of Medicine, who chaired the session, was taken aback by the findings, particularly by the worldwide increase in stroke cases.
“I work in stroke,” she said, and “we spend a lot of time on the diagnosis of stroke” and its prevention. “We try to be faster, to catch asymptomatic stenosis in the neck or head, and to apply the best medical treatment to avoid a stroke. But despite that, the numbers are increasing. I understand the population is getting older ... but still it’s a huge number.”
Dr. Valaikiene pointed out that stroke is not necessarily a condition of aging, insofar as increasing age “is not related directly to stenosis in the neck. “For example, we can have healthier vessels in older age and unhealthy vessels, with high-grade stenosis, in someone aged 30 or 40 years.”
“There are a lot of risk factors, such as smoking, physical activity, and so on. It depends on the individual,” she added.
The study was funded by the Institute for Health Metrics and Evaluation at the University of Washington. The authors have disclosed no relevant financial relationships.

– at huge cost to health care systems and society, an analysis of data from the most recent Global Burden of Disease (GBD) study shows.
“The burden of brain conditions will increase as populations continue to grow and age,” said study presenter Shayla Smith, MPH, an epidemiologist at the Institute for Health Metrics and Evaluation, the University of Washington, Seattle, in a press release.
“By 2050, more than 50 million people will be aged 65-79,” she explained, adding that the COVID-19 pandemic “has also influenced the prevalence of mental disorders globally, as people were forced to isolate and social networks broke down.”
Other factors related to brain disorders, she noted, include education level, obesity, and smoking.
“There’s still research to be done on what is the most effective way to maintain brain health, but some literature suggests a healthy brain can be achieved through a healthy lifestyle of managing conditions such as high blood pressure and diabetes, limiting alcohol consumption and smoking, prioritizing sleep, eating healthy, and staying physically and mentally active,” said Ms. Smith.
The findings were presented at the annual meeting of the Congress of the European Academy of Neurology.
An ‘ambitious exercise’
Coinvestigator Xaviera Steele, also from the IHME, told press conference attendees that the institute was established at the University of Washington in 2007 with the aim of “standardizing the measurement of health outcomes around the world and for all health conditions.”
A central part of that is the GBD study, “which is a very ambitious exercise in descriptive epidemiology in an effort to systematically quantify health loss” due to disease, injury, and risk factors over time, stratified by country, region, age, and sex. In addition, researchers are mapping and projecting trends over the next century and are estimating disease expenditure by country, by type of expense, and by condition “to derive a health care access and quality score for each health system in the world,” Ms. Steele said.
They are also estimating exposure to risk factors, how those risk factors contribute to health burden, and associated health outcomes by race and ethnicity to reflect the “disparities that we know are very prevalent in countries such as the United States.” From that work, Ms. Steele said that brain health and related conditions “do emerge as one of the more pressing challenges of the 21st century.”
Increase in dementia, mental health conditions
The data, which were gathered from 200,000 sources by the IHME, indicate that the number of individuals aged 65 years or older will increase by 350% by 2100. Ms. Steele underlined that “policy action will be needed to help families, who will struggle to provide high-quality care for their loved ones with dementia at a reasonable cost.”
The IHME calculates that in Europe health care spending on Alzheimer’s disease will increase by 226% between 2015 and 2040.
Turning to other conditions, Ms. Steele showed that since 1990, the number of individuals living with anxiety in the European region has increased by 14%, while the number living with depressive disorders has gone up by 13%.
Worldwide, the figures are even starker. Depression is estimated to affect 300 million people across the globe, which represents a 71% increase since 1990. The number of strokes increased by 95% over the same period.
Nevertheless, the “impact of brain conditions such as stroke has decreased since the 1990s due to improved treatments available,” Ms. Smith noted in the press release.

Hearing loss tied to more fatigue in middle and older age
Like many stressful chronic conditions, hearing loss appears to foster fatigue, according to an analysis of National Health and Nutrition Examination Study data published in JAMA Otolaryngology – Head & Neck Surgery.
Researchers at Johns Hopkins University, Baltimore, examined NHANES data from 2015 to 2016 and 2017 to 2018, including findings on more than 3,000 participants aged 40 and older. Based on the audiometry subset of NHANES data, hearing loss was associated with a higher frequency of fatigue – even after adjustment for demographics, comorbidities, and lifestyle variables such as smoking, alcohol, and body mass index, in a nationally representative sample of adults in middle and older age.
“We wanted to get away from small clinical data and take a look at the population level to see if hearing loss was related to fatigue and, further perhaps, to cognitive decline,” said coauthor Nicholas S. Reed, AuD, PhD, an assistant professor of epidemiology at Johns Hopkins University, Baltimore, in an interview. “We found people with hearing loss had twice the risk of reporting fatigue nearly every day versus those not reporting fatigue.” This cross-sectional study provides needed population-based evidence from a nationally representative sample, according to Dr. Reed and associates, who have been researching the possible connection between age-related hearing loss, physical activity levels, and cognitive decline.
Study details
The 3,031 age-eligible participants had a mean age of 58 years; 48% were male, and 10% were Black. Some hearing loss was reported by 24%.
They responded to the following question: “Over the last 2 weeks, how often have you been bothered by feeling tired or having little energy?” Response categories were “not at all,” “several days,” “more than half the days,” and “nearly every day.” Those with hearing loss were more likely to report fatigue for more than half the days (relative risk ratio, 2.16; 95% confidence interval, 1.27-3.67) and nearly every day (RRR, 2.05; 95% CI, 1.16-3.65), compared with not having fatigue. Additional adjustment for comorbidities and depressive symptoms showed similar results.
Hearing loss was defined as > 25 decibels hearing level (dB HL) versus normal hearing of ≤ 25 dB HL, and continuously by every 10 dB HL poorer. Each 10-dB HL of audiometric hearing loss was associated with a higher likelihood of reporting fatigue nearly every day (RRR, 1.24; 95% CI,1.04-1.47), but not for more than half the days.
The association tended to be stronger in younger, non-Hispanic White, and female participants, but statistical testing did not support differential associations by age, sex, race, or ethnicity.
While some might intuitively expect hearing loss to cause noticeably more fatigue in middle-aged people who may be straining to hear during hours in the daily workplace or at home, Dr. Reed said older people probably feel more hearing-related fatigue owing to age and comorbidities. “And higher physical activity levels of middle-aged adults can be protective.”
Dr. Reed advised primary care physicians to be sure to ask about fatigue and hearing status during wellness exams and take appropriate steps to diagnose and correct hearing problems. “Make sure hearing is part of the health equation because hearing loss can be part of the culprit. And it’s very possible that hearing loss is also contributing to cognitive decline.”
Dr. Reed’s group will soon release data on a clinical trial on hearing loss and cognitive decline.
The authors called for studies incorporating fatigue assessments in order to clarify how hearing loss might contribute to physical and mental fatigue and how it could be associated with downstream outcomes such as fatigue-related physical impairment. Dr. Reed reported grants from the National Institute on Aging during the conduct of the study and stock compensation from the Neosensory Advisory Board outside of the submitted work. Several coauthors reported academic or government research funding as well as fees and honoraria from various private-sector companies.

FROM JAMA OTOLARYNGOLOGY – HEAD & NECK SURGERY
Finding mild cognitive impairment quickly in primary care
Primary care is the ideal setting to screen for mild cognitive impairment. Screening can be performed in under 10 minutes using brief cognitive assessment tools. When it comes to treatment, deprescribing is a priority, as many drug interactions contribute to cognitive disorders. Drugs also influence the value of nondrug therapies.
At the XXIX National Congress of General and Family Medicine of the Spanish Society for General and Family Physicians, Granada, Spain, Alberto Freire, MD, a family doctor and head of the society’s neurology group, presented a way to detect cognitive impairment in a few minutes during a primary care office visit. He also presented a stepwise algorithm for diagnosing and treating the condition, which is highly prevalent and underdiagnosed.
The specialist dismissed the idea that “memory problems are associated with age,” though it is true that in normal aging, “cognitive frailty develops, and some processes will move a little slower. But there won’t be significant functional impairment.” Mild cognitive impairment falls between normal aging and dementia.
“Primary care is essential for screening for mild cognitive impairment due to its high level of accessibility, proximity, and continuity, but most of all due to its longitudinal perspective, which differentiates it from other specialties,” said Dr. Freire. He pointed out that screening is not the same as diagnosis because screening merely indicates probability or well-founded suspicion that can then be confirmed in secondary care.
He also highlighted the need for assessment of cognitive function using brief cognitive tests, as well as the need for functional assessment of activities of daily living. Many cognitive function tests are available, some of which are patient oriented and some caregiver oriented.
“The patient initially comes to see us due to memory loss that he or she, or that some reliable reporter, has detected,” said Dr. Freire. He indicated that 18.5% of consultations for cognitive impairment are prompted by subjective perceptions of memory complaints, which represent the most common subtype of the condition: mild amnestic cognitive impairment.
Quick cognitive tests
Dr. Freire was in favor of picture-based tests, which he strongly recommended. “These are the most-studied tests in Spain for detecting neurocognitive impairment, and they eliminate the reading factor. They’re quick, they’re easy to use and interpret, and are well-accepted by patients. Also, they assess executive function (verbal fluency) and memory.” Dr. Freire stressed the importance of referencing categories when showing the pictures, as well as the fact that the test is available for free online.
He also questioned whether the Mini-Mental State Examination is dead because “there’s an abbreviated version that the author rejects, and the author’s permission is required to use it. It’s very appropriate for Alzheimer’s disease, but not for cognitive impairment.”
Another notable test is the episodic test (a test that avoids interfering with working memory). It has been validated for amnestic mild cognitive impairment and Alzheimer’s disease, but a reliable caregiver is required to verify patient responses.
For caregiver-oriented tests, Dr. Freire pointed to AD8, which, when paired with any brief cognitive test, significantly increases detection of cognitive impairment.
He also recommended a useful website for everyday consultations created by several scientific societies, including the Spanish Society of General and Family Physicians. The site includes the AD8 and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) questionnaires that can be completed online. “It produces a score that indicates the likelihood that the patient has cognitive impairment, and it can be filled out by family members or caregivers to get the result during the consultation,” he said.
Functional assessment
“Functional assessment of the patient’s level of independence for their life in society is what conceptually differentiates mild cognitive impairment from dementia,” explained Dr. Freire. “There are several types of activities of daily living. The instrumental activities (cooking, laundry, talking on the phone, using transportation, managing finances, taking medications, etc.) are the activities that truly distinguish between mild cognitive impairment and dementia. They allow the person to adjust to their environment and retain their independence within the community.”
There are multiple tools for assessing activities of daily living, but Dr. Freire singled out the Mongil test (from Spain), which covers basic, instrumental, and advanced activities. The higher the score, the worse the patient’s condition, so the goal is to lower the score. On the other hand, grouping certain items together helps determine whether there is a risk of falling, sarcopenia, depression, or suicide, among other outcomes. “So, it’s not only useful for diagnosis and treatment but also detects geriatric problems and syndromes. That is, it’s useful for prevention and allows planning of preventive and therapeutic medical interventions,” he explained.
Reversible dementia
Dr. Freire presented a diagnostic and therapeutic algorithm for cognitive impairment to be used when brief cognitive tests are positive. “The first thing is to perform a clinical assessment because although many cases of cognitive impairment go undiagnosed, 10% of the cases of symptomatic dementia are potentially reversible. We shouldn’t overlook these.” These cases of dementia may be brought on by medication use, alcoholism, chronic meningoencephalitis, toxins, normal pressure hydrocephalus, certain brain tumors, hypothyroidism, and nutritional deficits, among other causes. Functional assessment follows, using the scales mentioned above.
Interactions and deprescribing
“As to polypharmacy, there is underuse of good, evidence-backed medications with no major contraindications. But care must also be taken with inappropriate or off-label medications, overtreatment, drug interactions, and adherence,” said Dr. Freire.
“We need to start deprescribing because the chemical basis of cognitive impairment traces back to reduced cholinergic activity, increased dopaminergic activity in the brain, or both. There are many commonly prescribed drugs with anticholinergic interactions that can cause cognitive disorders. These could be psychotropics, hypnotics, analgesics (nonsteroidal anti-inflammatory drugs), first-generation antihistamines, antihypertensives, antiarrhythmics, histamine2 blockers, and even antibiotics like penicillin and quinolones, among many others,” he emphasized.
The next step is to perform comprehensive laboratory testing to rule out vitamin and mineral deficiencies, diabetes, thyroid disorders, kidney failure, liver diseases, urinary infections, and infections of the central nervous system. After that, neuroimaging should be performed. MRI is the preferred method because it allows quantification of atrophy and volumetric measurements.
Strict cardiovascular control
“At this point, treatment can be started, and the patient can be referred to secondary care,” said Dr. Freire, as he proceeded through a therapeutic algorithm following diagnosis of the patient. Regular exercise increases coordination synapses, prevents disease onset, improves executive function, and delays the onset of dementia. “The problem lies in not knowing how much time should be spent daily and weekly on exercise to achieve these goals.
“It is known that a Mediterranean diet and omega-3 fatty acids improve cognitive impairment. However, care should be taken with omega-3s as they are no longer helpful in dementia that has already been established.” The importance of strictly controlling cardiovascular risk factors must also be kept in mind, as backed by validated studies; it has been shown that blood pressure levels below 128 mm Hg make mild cognitive impairment and dementia worse, atrial fibrillation increases the risk of dementia by a factor of 1.4-2.4, diabetes is a risk factor for developing amnestic mild cognitive impairment, tobacco use also leads to cognitive impairment – even in individuals exposed to second-hand smoke – and statins do not change the risk in cases of dyslipidemia.
Nondrug treatment
Dr. Freire also highlighted the importance of multiple nondrug therapies in this field, such as cognitive training and rehabilitation, reminiscence, music therapy, cognitive-behavioral psychotherapy, and sensory interventions, among others. He also recommended patient groups for these individuals.
He added: “In mild cognitive impairment, there is currently no drug that is an improvement over nondrug therapies.”
The drugs aim to improve memory loss, prevent or delay the onset of mild cognitive impairment, and treat initial symptoms of dementia if applicable. The most commonly prescribed drugs are citicoline alone in vascular disease and memory loss, EGb 761 (which is the only approved dose-dependent drug), and others such as phosphatidylserine, nimodipine, and memantine combined with galantamine or piracetam, Dr. Freire concluded.
Dr. Freire had declared receiving funding as a student in training and outreach activities for popular science sponsored by Ferrer, and on the topic of pain by Esteve, Grünenthal Pharma, and Menarini. He has also reported being a consultant for GSK, Lilly, and Pfizer.

However, care should be taken with omega-3s as they are no longer helpful in dementia that has already been established.” The importance of strictly controlling cardiovascular risk factors must also be kept in mind, as backed by validated studies; it has been shown that blood pressure levels below 128 mm Hg make mild cognitive impairment and dementia worse, atrial fibrillation increases the risk of dementia by a factor of 1.4-2.4, diabetes is a risk factor for developing amnestic mild cognitive impairment, tobacco use also leads to cognitive impairment – even in individuals exposed to second-hand smoke – and statins do not change the risk in cases of dyslipidemia.
Nondrug treatment
Dr. Freire also highlighted the importance of multiple nondrug therapies in this field, such as cognitive training and rehabilitation, reminiscence, music therapy, cognitive-behavioral psychotherapy, and sensory interventions, among others. He also recommended patient groups for these individuals.
He added: “In mild cognitive impairment, there is currently no drug that is an improvement over nondrug therapies.”
The drugs aim to improve memory loss, prevent or delay the onset of mild cognitive impairment, and treat initial symptoms of dementia if applicable. The most commonly prescribed drugs are citicoline alone in vascular disease and memory loss, EGb 761 (which is the only approved dose-dependent drug), and others such as phosphatidylserine, nimodipine, and memantine combined with galantamine or piracetam, Dr. Freire concluded.
Dr. Freire had declared receiving funding as a student in training and outreach activities for popular science sponsored by Ferrer, and on the topic of pain by Esteve, Grünenthal Pharma, and Menarini. He has also reported being a consultant for GSK, Lilly, and Pfizer.

Primary care is the ideal setting to screen for mild cognitive impairment. Screening can be performed in under 10 minutes using brief cognitive assessment tools. When it comes to treatment, deprescribing is a priority, as many drug interactions contribute to cognitive disorders. Drugs also influence the value of nondrug therapies.
At the XXIX National Congress of General and Family Medicine of the Spanish Society for General and Family Physicians, Granada, Spain, Alberto Freire, MD, a family doctor and head of the society’s neurology group, presented a way to detect cognitive impairment in a few minutes during a primary care office visit. He also presented a stepwise algorithm for diagnosing and treating the condition, which is highly prevalent and underdiagnosed.
The specialist dismissed the idea that “memory problems are associated with age,” though it is true that in normal aging, “cognitive frailty develops, and some processes will move a little slower. But there won’t be significant functional impairment.” Mild cognitive impairment falls between normal aging and dementia.
“Primary care is essential for screening for mild cognitive impairment due to its high level of accessibility, proximity, and continuity, but most of all due to its longitudinal perspective, which differentiates it from other specialties,” said Dr. Freire. He pointed out that screening is not the same as diagnosis because screening merely indicates probability or well-founded suspicion that can then be confirmed in secondary care.
He also highlighted the need for assessment of cognitive function using brief cognitive tests, as well as the need for functional assessment of activities of daily living. Many cognitive function tests are available, some of which are patient oriented and some caregiver oriented.
“The patient initially comes to see us due to memory loss that he or she, or that some reliable reporter, has detected,” said Dr. Freire. He indicated that 18.5% of consultations for cognitive impairment are prompted by subjective perceptions of memory complaints, which represent the most common subtype of the condition: mild amnestic cognitive impairment.
Quick cognitive tests
Dr. Freire was in favor of picture-based tests, which he strongly recommended. “These are the most-studied tests in Spain for detecting neurocognitive impairment, and they eliminate the reading factor. They’re quick, they’re easy to use and interpret, and are well-accepted by patients. Also, they assess executive function (verbal fluency) and memory.” Dr. Freire stressed the importance of referencing categories when showing the pictures, as well as the fact that the test is available for free online.
He also questioned whether the Mini-Mental State Examination is dead because “there’s an abbreviated version that the author rejects, and the author’s permission is required to use it. It’s very appropriate for Alzheimer’s disease, but not for cognitive impairment.”
Another notable test is the episodic test (a test that avoids interfering with working memory). It has been validated for amnestic mild cognitive impairment and Alzheimer’s disease, but a reliable caregiver is required to verify patient responses.
For caregiver-oriented tests, Dr. Freire pointed to AD8, which, when paired with any brief cognitive test, significantly increases detection of cognitive impairment.
He also recommended a useful website for everyday consultations created by several scientific societies, including the Spanish Society of General and Family Physicians. The site includes the AD8 and Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) questionnaires that can be completed online. “It produces a score that indicates the likelihood that the patient has cognitive impairment, and it can be filled out by family members or caregivers to get the result during the consultation,” he said.
Functional assessment
“Functional assessment of the patient’s level of independence for their life in society is what conceptually differentiates mild cognitive impairment from dementia,” explained Dr. Freire. “There are several types of activities of daily living. The instrumental activities (cooking, laundry, talking on the phone, using transportation, managing finances, taking medications, etc.) are the activities that truly distinguish between mild cognitive impairment and dementia. They allow the person to adjust to their environment and retain their independence within the community.”
There are multiple tools for assessing activities of daily living, but Dr. Freire singled out the Mongil test (from Spain), which covers basic, instrumental, and advanced activities. The higher the score, the worse the patient’s condition, so the goal is to lower the score. On the other hand, grouping certain items together helps determine whether there is a risk of falling, sarcopenia, depression, or suicide, among other outcomes. “So, it’s not only useful for diagnosis and treatment but also detects geriatric problems and syndromes. That is, it’s useful for prevention and allows planning of preventive and therapeutic medical interventions,” he explained.
Reversible dementia
Dr. Freire presented a diagnostic and therapeutic algorithm for cognitive impairment to be used when brief cognitive tests are positive. “The first thing is to perform a clinical assessment because although many cases of cognitive impairment go undiagnosed, 10% of the cases of symptomatic dementia are potentially reversible. We shouldn’t overlook these.” These cases of dementia may be brought on by medication use, alcoholism, chronic meningoencephalitis, toxins, normal pressure hydrocephalus, certain brain tumors, hypothyroidism, and nutritional deficits, among other causes. Functional assessment follows, using the scales mentioned above.
Interactions and deprescribing
“As to polypharmacy, there is underuse of good, evidence-backed medications with no major contraindications. But care must also be taken with inappropriate or off-label medications, overtreatment, drug interactions, and adherence,” said Dr. Freire.
“We need to start deprescribing because the chemical basis of cognitive impairment traces back to reduced cholinergic activity, increased dopaminergic activity in the brain, or both. There are many commonly prescribed drugs with anticholinergic interactions that can cause cognitive disorders. These could be psychotropics, hypnotics, analgesics (nonsteroidal anti-inflammatory drugs), first-generation antihistamines, antihypertensives, antiarrhythmics, histamine2 blockers, and even antibiotics like penicillin and quinolones, among many others,” he emphasized.
The next step is to perform comprehensive laboratory testing to rule out vitamin and mineral deficiencies, diabetes, thyroid disorders, kidney failure, liver diseases, urinary infections, and infections of the central nervous system. After that, neuroimaging should be performed. MRI is the preferred method because it allows quantification of atrophy and volumetric measurements.
Strict cardiovascular control
“At this point, treatment can be started, and the patient can be referred to secondary care,” said Dr. Freire, as he proceeded through a therapeutic algorithm following diagnosis of the patient. Regular exercise increases coordination synapses, prevents disease onset, improves executive function, and delays the onset of dementia. “The problem lies in not knowing how much time should be spent daily and weekly on exercise to achieve these goals.
“It is known that a Mediterranean diet and omega-3 fatty acids improve cognitive impairment. However, care should be taken with omega-3s as they are no longer helpful in dementia that has already been established.” The importance of strictly controlling cardiovascular risk factors must also be kept in mind, as backed by validated studies; it has been shown that blood pressure levels below 128 mm Hg make mild cognitive impairment and dementia worse, atrial fibrillation increases the risk of dementia by a factor of 1.4-2.4, diabetes is a risk factor for developing amnestic mild cognitive impairment, tobacco use also leads to cognitive impairment – even in individuals exposed to second-hand smoke – and statins do not change the risk in cases of dyslipidemia.

Men and women react differently to acute stress
Topline
Methodology
- The study included 80 healthy participants, mean age 24 years.
- Half the subjects immersed their nondominant hand (including the wrist) in ice water for up to 3 minutes; the other half, which served as the control group, immersed their hand in warm water for 3 minutes.
- Participants were asked to deliberately downregulate emotional responses to high-intensity negative pictures.
- Participants regularly provided saliva samples to check cortisol levels and were monitored for cardiovascular activity.
- Researchers assessed pupil dilation, which along with subject ratings of their affective state served as emotion regulation (ER) outcome measures.
Takeaway
- In men, stress rapidly improved the ability to downregulate emotional arousal via distraction that was fully mediated by cortisol.
- In women, sympathetic nervous system (SNS) reactivity was linked to decreased regulatory performances.
- Direct stress effects on ER were smaller than expected.
In practice
The study contributes to a “better understanding of the neuroendocrinological mechanisms of stress effects on ER that may help to develop adequate preventive and curative interventions of stress- and emotion-related disorders,” the researchers write.
Source
The study was conducted by Katja Langer, Valerie Jentsch, and Oliver Wolf from the Department of Cognitive Psychology, Ruhr University Bochum (Germany). It was published in the May 2023 issue of Psychoneuroendocrinology.
Limitations
The results have some inconsistencies. The ER paradigm is somewhat artificial and not fully comparable with emotional trigger and regulatory requirements in everyday life. The study did not directly assess levels of catecholamines such as adrenaline and noradrenaline.
Disclosures
The study received support from the German Research Foundation (DFG). The authors have no reported conflicts of interest.

Smartwatches able to detect very early signs of Parkinson’s
new research shows.
An analysis of wearable motion-tracking data from UK Biobank participants showed a strong correlation between reduced daytime movement over 1 week and a clinical diagnosis of PD up to 7 years later.
“Smartwatch data is easily accessible and low cost. By using this type of data, we would potentially be able to identify individuals in the very early stages of Parkinson’s disease within the general population,” lead researcher Cynthia Sandor, PhD, from Cardiff (Wales) University, said in a statement.
“We have shown here that a single week of data captured can predict events up to 7 years in the future. With these results we could develop a valuable screening tool to aid in the early detection of Parkinson’s,” she added.
“This has implications both for research, in improving recruitment into clinical trials, and in clinical practice, in allowing patients to access treatments at an earlier stage, in future when such treatments become available,” said Dr. Sandor.
The study was published online in Nature Medicine.
Novel biomarker for PD
Using machine learning, the researchers analyzed accelerometry data from 103,712 UK Biobank participants who wore a medical-grade smartwatch for a 7-day period during 2013-2016.
At the time of or within 2 years after accelerometry data collection, 273 participants were diagnosed with PD. An additional 196 individuals received a new PD diagnosis more than 2 years after accelerometry data collection (the prodromal group).
The patients with prodromal symptoms of PD and those who were diagnosed with PD showed a significantly reduced daytime acceleration profile up to 7 years before diagnosis, compared with age- and sex-matched healthy control persons, the researchers found.
The reduction in acceleration both before and following diagnosis was unique to patients with PD, “suggesting this measure to be disease specific with potential for use in early identification of individuals likely to be diagnosed with PD,” they wrote.
Accelerometry data proved more accurate than other risk factors (lifestyle, genetics, blood chemistry) or recognized prodromal symptoms of PD in predicting whether an individual would develop PD.
“Our results suggest that accelerometry collected with wearable devices in the general population could be used to identify those at elevated risk for PD on an unprecedented scale and, importantly, individuals who will likely convert within the next few years can be included in studies for neuroprotective treatments,” the researchers conclude in their article.
High-quality research
In a statement from the U.K.-based nonprofit Science Media Centre, José López Barneo, MD, PhD, with the University of Seville (Spain), said this “good quality” study “fits well with current knowledge.”
Dr. Barneo noted that other investigators have also observed that slowness of movement is a characteristic feature of some people who subsequently develop PD.
But these studies involved preselected cohorts of persons at risk of developing PD, or they were carried out in a hospital that required healthcare staff to conduct the movement analysis. In contrast, the current study was conducted in a very large cohort from the general U.K. population.
Also weighing in, José Luis Lanciego, MD, PhD, with the University of Navarra (Spain), said the “main value of this study is that it has demonstrated that accelerometry measurements obtained using wearable devices (such as a smartwatch or other similar devices) are more useful than the assessment of any other potentially prodromal symptom in identifying which people in the [general] population are at increased risk of developing Parkinson’s disease in the future, as well as being able to estimate how many years it will take to start suffering from this neurodegenerative process.
“In these diseases, early diagnosis is to some extent questionable, as early diagnosis is of little use if neuroprotective treatment is not available,” Dr. Lanciego noted.
“However, it is of great importance for use in clinical trials aimed at evaluating the efficacy of new potentially neuroprotective treatments whose main objective is to slow down – and, ideally, even halt ― the clinical progression that typically characterizes Parkinson’s disease,” Dr. Lanciego added.
The study was funded by the UK Dementia Research Institute, the Welsh government, and Cardiff University. Dr. Sandor, Dr. Barneo, and Dr. Lanciego have no relevant disclosures.
