Researchers Explore Blood Tests for Earlier Alzheimer’s Detection, While Experts Emphasize Healthy Habits
Researchers say exercise, diet and blood pressure control can add nearly 13 dementia-free years, while blood tests remain unreliable for symptom-free adults.
- The Food and Drug Administration has cleared four blood tests to diagnose Alzheimer in symptomatic patients, yet Nicholas Ashton of Banner Health stressed "the worried well should not be getting those tests" outside research.
- Managing high blood pressure, smoking, and diabetes is crucial, as avoiding these conditions extends dementia-free life by nearly 13 years. Josef Coresh of NYU Langone Health found reaching middle age without these issues offers significant long-term brain health benefits.
- A major trial found that half-hour sessions of moderately intense exercise four times weekly and twice-weekly resistance training slowed age-related cognitive decline. Experts also advise following the MIND diet, getting enough sleep, and treating hearing loss.
- Testing asymptomatic individuals carries risks, as a "positive" result is merely a risk factor rather than a guarantee of developing Alzheimer. Mark Yost, who received an "intermediate" result, found the uncertainty "a little disappointing."
- Clinical trials are investigating whether Alzheimer drugs might help certain people before they develop symptoms, findings that could eventually shift testing advice. For now, experts maintain individuals should prioritize addressing preventable brain risks.
