Simple Blood Test Can Predict Dementia Risk in Women Decades Before Symptoms
Diagnostic tests are continuing to get better at spotting the earliest signs of dementia, and new research suggests that a simple blood sample could help identify those at most risk, some 25 years before symptoms start showing. Warning is crucial with conditions like dementia. It gives more time for preventative treatments to be put in place, for support and care to be prepared, and for researchers to study the biological processes involved. In …
Alzheimer's: A simple blood test could reveal the disease 25 years before the first symptoms And if a routine analysis, apparently banal, would ever be enough to say if you risk losing your memory in 20 years? For many people who fear Alzheimer's disease, the idea of a simple bottle of blood capable of projecting such a future makes as much hope as it worries. U.S. research teams have looked at this issue by following for decades thousands of ol…
Anticipating dementia decades before its first clinical signs: this is the horizon of a new American study published in JAMA Network Open. Researchers from several American institutions analyzed the blood samples of nearly 2,800 cognitively healthy women in the 1990s, and then followed their brain development on a large scale. ...

UCSD study: Simple blood test may predict dementia decades early
A new study from the University of California, San Diego, suggests a simple blood test could help predict dementia decades before symptoms appear.Researchers analyzed blood samples from more than 2,700 women between the ages of 65 and 79 who were part of a large national memory study that began in the late 1990s. They measured a protein in the blood called p-tau217 and then followed the women for up to 25 years to see who later developed dementi…
What if a simple extraction could tell you well in advance of a risk that is usually detected late today? A study published on JAMA Network Open suggests that a blood test with a biomarker called p-tau217 is associated with the probability of developing mild cognitive impairment or dementia in women, even up to 25 years before clear symptoms appear. The idea is easy to understand: certain biological changes linked to Alzheimer’s may start long b…
