A new blood test could determine a woman’s dementia risk as early as 25 years before symptoms emerge.

That’s according to new research from the University of California San Diego, which found that a specific biomarker protein associated with early pathological processes of Alzheimer’s disease was “strongly linked” to future dementia risk.

The researchers analyzed blood samples from 2,766 participants in the Women’s Health Initiative Memory Study in the late 1990s, according to the study’s press release.

The women ranged from 65 to 79 years of age and showed no signs of cognitive decline at the start of the study.

After tracking the participants for up to 25 years, the researchers concluded that the biomarker phosphorylated tau 217 (p-tau217) was “strongly associated” with future mild cognitive impairment and dementia.

Women who had higher levels of p-tau217 at the beginning of the study were “much more likely” to develop the disease. The findings were published today in JAMA Network Open.

“The key takeaway is that our study suggests it may be possible to detect risk of dementia two decades in advance using a simple blood test in older women,” first author Aladdin H. Shadyab, a UC San Diego associate professor of public health and medicine, told Fox News Digital. 

“These biomarkers may help us identify who is at greatest risk and develop strategies to delay or prevent dementia.”

“Our findings show that the blood biomarker p-tau217 could help identify individuals at higher risk for dementia long before symptoms begin,” he added.

This long lead time could open the door to earlier prevention strategies and more targeted monitoring, rather than waiting until memory problems are already affecting daily life, according to Shadyab.

“As the research advances, these biomarkers may help us identify who is at greatest risk and develop strategies to delay or prevent dementia,” he said.

This risk relationship wasn’t the same across the board, however. Women over 70 with higher p-tau217 levels had “poorer cognitive outcomes” compared to those under 70, as did those with the APOE ε4 gene, which is a known risk factor for Alzheimer’s disease.

The study also found that p-tau217 was a stronger predictor of dementia in women who were randomly assigned to receive estrogen and progestin hormone therapy compared to those who received a placebo.

“Blood-based biomarkers like p-tau217 are especially promising because they are far less invasive and potentially more accessible than brain imaging or spinal fluid tests,” said senior author Linda K. McEvoy, senior investigator at Kaiser Permanente Washington Health Research Institute and professor emeritus at the Herbert Wertheim School of Public Health, in the release.

“This is important for accelerating research into the factors that affect the risk of dementia and for evaluating strategies that may reduce risk.”

Blood tests for Alzheimer’s disease are still being studied and are not recommended for routine screening in people without symptoms, Shadyab noted.

More research is needed before this approach can be considered for clinical use prior to cognitive symptoms. 

Future studies should investigate how other factors — like genetics, hormone therapy and age-related medical conditions — might interact with plasma p-tau217, the researchers added.

“The study examined only older women, so the findings may not necessarily apply to men or younger populations,” Shadyab noted. “We also examined overall dementia outcomes rather than specific subtypes such as Alzheimer’s disease.”

Leading oncologist reveals 6 habits that could promote longevity and reduce your risk of chronic illness

Leading oncologist reveals 6 habits that could promote longevity and reduce your risk of chronic illness

NEWYou can now listen to Fox News articles!

The health and wellness information put out on television, podcasts, social media, websites and elsewhere can be overwhelming, but a leading oncologist and University of Pennsylvania bioethicist argues healthy aging can be simplified into six evidence-based rules.

“Don’t be a schmuck” is the first principle offered by Dr. Ezekiel Emanuel in his book, “Eat Your Ice Cream: Six Simple Rules for a Long and Healthy Life.”

“Don’t be stupid,” Emanuel said recently on the ZOE Science & Nutrition podcast. “This is something my father used to say to his three sons very commonly when we were doing something dumb.”

Emanuel’s brothers are former Chicago Mayor Rahm Emanuel and powerful talent agent Ari Emanuel.

Emanuel argued that obviously dangerous activities, such as BASE jumping, climbing Mount Everest and smoking and vaping are examples of being a schmuck because they carry a high risk of death.

His other principles for living longer and reducing disease risk include prioritizing an active social life, staying mentally active with new hobbies and opportunities to learn, limiting processed and sugary foods and drinks without being overly restrictive, engaging in moderate exercise and getting proper sleep.

“Our entire brain is constructed around social interactions, and it does way more for us,” Emanuel said. “We know that if you’re lonely, socially isolated, you dramatically increase your risks of mortality.

“More than 3 million people worldwide have been enrolled in studies about social interaction and longevity,” he added. “And the socially isolated, people who have zero or one friends, don’t see friends a lot. Those people are much more likely to die in the next few years.”

A leading health expert argues that loneliness poses health risks comparable to smoking cigarettes. (iStock)

According to Emanuel, being socially isolated or lonely “is the equivalent of smoking 15 cigarettes a day.”

Both close relationships and casual social interactions contribute to well-being, he said.

Emanuel explained why he thinks much of society’s obsession with wellness is toxic and what he labels as “the wellness industrial complex” gets wrong.

“You should not be obsessed about wellness,” Emanuel said on the podcast. “You should be obsessed about living a meaningful life. That’s really what’s important, and wellness is only a means to an end.”

Much of the wellness industry focuses on self-denial, which is misguided, said Emanuel.

“Biology for humans is about homeostasis, the balance between one extreme and another,” he said.

Society’s current obsession with wellness is nothing new, he added.

“Wellness is a response to a topsy-turvy world, a lot of uncertainty about what the future’s bringing, people feeling like their life’s out of control,” he said. 

“And, so, wellness is a response. This is something I can control — what I eat, the vaccines I get, the exercise — and I think that’s what we have today. This is a lot about self-control transmuted into wellness as the outlet.”

Dr. Ezekiel Emanuel said he is a teetotaler himself but says he serves alcohol at his dinner parties because he believes it acts as a social lubricant. (iStock)

The body thrives when it doesn’t take dieting or exercising to extremes, Emanuel said. He is a teetotaler himself, but his wife enjoys cocktails, and when they have a dinner party, they serve alcohol.

Don’t drink alone or use alcohol to drown your sorrows or avoid dealing with them, Emanuel advised.

The ZOE podcast asked Emanuel to advise listeners who aren’t following any of his six rules what to try first.

“Dinner parties,” he said. “You cook, and you both have good, healthy food because you’ve cooked it. Ynd you’ve challenged your mind ‘cause you’re adding a new recipe, and you’re figuring out how to do it right.

“You have people over, so you’ve got social connections,” he continued. “You’re challenging your mind with a good conversation. And when it’s all over, you go out for a walk so you get some physical activity. 

“This is like you’ve done almost everything in wellness. All of those elements are key to wellness, and it’s the kind of thing you can do, you know, once a weekend or … And you’ll be happier.”

Weight-loss drugs may improve job prospects and dating odds for one group

Weight-loss drugs may improve job prospects and dating odds for one group

A recent study suggests GLP-1-related weight loss may improve some women’s relationships and employment status.

Rebecca Diamond, professor of economics at Harvard University in Boston, independently published research that found an association between weight-loss medications and a change in women’s social and economic outcomes.

Diamond used the Understanding America Study, a panel survey from the University of Southern California, to compare women who started GLP-1s for weight loss to those who wanted to start but had not yet done so.

The comparison considered body mass, health, income, employment, partnership status and well-being before treatment.

The study focused on women because they are more likely to use GLP-1s than men. It excluded people taking GLP-1 drugs for diabetes, as their use is driven by a medical condition rather than weight-loss demand.

Women who successfully lost weight with GLP-1 medications experienced changes across several life outcomes, including employment, marriage and cohabitation, according to the study.

Marriage and cohabitation rose 29% for single women after about 18 months.

Among women who were not employed at the start of the study, job prospects increased by 27% after the same amount of time. Those who were already employed did not display any clear upward progress in their careers, however.

Diamond argues that these findings suggest part of the “female obesity penalty” comes from how people are judged when being matched up, either in a new relationship or a new job.

The findings say “more about societal bias than about the medication itself,” a doctor suggested. (iStock)

Dr. Peter Balazs, MD, a hormone and weight-loss specialist from New York and New Jersey, commented on these findings.

“The effects showed up during ‘new match’ situations, such as job interviews or dating, and not within existing jobs or relationships,” Balazs, who was not involved in the study, told Fox News Digital. “This says more about societal bias than it does about the medication itself.”

Balazs said his patients often report feeling more confident and “visible” after weight loss, which could translate into better interview performance and networking.

“Weight loss (commonly) improves confidence, which opens new business and relationship opportunities,” he went on. “Weight loss has hormonal impacts as well, so the normalization of hormones and the profound metabolic and psychological relief that comes with it can be a factor, too.”

Dr. Krishna Vyas, a plastic surgeon at Blechman Plastic Surgery in New York, told Fox News Digital in a separate interview that many patients seek breast lifts or body contouring after significant GLP-1 weight loss, after which they find themselves “re-engaging with life.”

“That confidence effect is real in the exam room,” said the surgeon, who also was not involved in the research. “This study, however, showed no clear improvement in depression, loneliness or life satisfaction, even as marriage and employment rates climbed dramatically.”

“The opportunities opened, yet the women didn’t report feeling better, which suggests it was largely the gatekeepers who changed, not the women.”

Potential limitations

Because this was an observational study rather than a randomized clinical trial, it could only show an association — not cause and effect. The findings are also considered preliminary because the paper has not yet been peer-reviewed, the author acknowledged.

“Additionally, since the study only looked at women, that introduces another layer of potential bias,” Balazs noted. “I’d be interested to see whether the findings would be the same if the study included men or compared them directly.”

“Weight loss has hormonal impacts as well, so the normalization of hormones and the profound metabolic and psychological relief that comes with it can be a factor, too,” an expert said. (iStock)

Another limitation is that the information from the individuals studied was self-reported, the expert noted. 

The researchers were also unable to determine whether people who found new jobs were earning more money.

“Additionally, even though GLP-1 users appeared to have better outcomes on paper, they did not report greater overall life satisfaction,” Balazs added. “That raises important questions about whether these external changes translate into meaningful improvements in well-being.”
