Toronto and UCSF researchers report that older women with higher levels of 16 menopause-linked molecules were 15 percent likelier to develop Alzheimer's. The authors see menopause as a window for early-warning testing, though the evidence so far is a correlation.
Reality
Boston University researchers used language software on story-recall recordings to flag mild cognitive impairment and forecast lower scores seven years later. The test is one clinics already give, so the open question for a cheap screen is how much the speech adds to the ordinary score.
Reality
Emory researchers link 5,000 IU a day to better cognitive screening scores in people with mild cognitive impairment and sleep disturbance. The exposure sits above the recommended safety ceiling.
Reality
Wake Forest researchers following 3,873 adults over 50 linked social support to slower attention decline, with no offset for losses tied to chronic stress. Because the data are observational, they point to stress as its own prevention target without testing any program.
Reality
An NIH-funded UC Berkeley team dosed old, healthy female mice, then fed a second group 24% fewer calories to match what the drug's appetite suppression achieved. The drug still did more on memory and blood sugar.
Reality
A Berkeley group ran the drug against a matched 24 percent food cut and found it equalled dieting on strength and coordination while beating it on memory and glucose. The lifespan race between the two is still running.

Flinders University followed nearly 10,000 women over 65 for a decade and found tea drinkers with slightly denser hips, while coffee tracked with thinner bone only past five cups a day. That is a statement about dose, pinned to intake above five cups a day.

The LifeAfter90 cohort has followed more than 800 Kaiser Permanente members who reached 90 without dementia, and the disparities look much as they do at 65: women at roughly twice men's risk, APOE2 still protective.
