Women’s verbal memory may delay alzheimer’s diagnosis by years

Women maintain normal scores on standard memory tests for nearly three years longer than men even after Alzheimer’s-related brain changes begin. This cognitive advantage can mask early signs of the disease and delay treatment. A new analysis of long-term studies in the US and Canada highlights the issue.

Researchers led by Sasha Novozhilova at McGill University examined data from older adults who underwent regular cognitive tests and brain scans. Participants recalled lists of 15 words in immediate, delayed, and distracted conditions. Women with significant amyloid buildup in their brains continued to score normally for an average of 2.7 years longer than men with comparable pathology.

A new study shows that blood tests can detect signs of Alzheimer's several years before the disease develops. American researchers published the findings in The Lancet.

Study finds alzheimer's risk factors hit women harder

New research from the University of California San Diego shows that several common dementia risk factors affect women's cognitive performance more strongly than men's. The findings help explain why women account for nearly two thirds of Alzheimer's cases in the United States.

People who reported more mentally stimulating experiences from childhood through older age were less likely to develop Alzheimer’s disease and tended to develop symptoms years later than peers with the lowest enrichment, according to an observational study published in Neurology.

Woman with Alzheimer's regains speech after psilocybin treatment

June 22, 2026 由 AI 报道

An 83-year-old woman with severe Alzheimer’s disease began speaking in full sentences and regained bladder control after taking a large dose of psilocybin. The changes occurred following a single session with the psychedelic compound derived from magic mushrooms. Researchers describe the case as dramatic but stress it is only one anecdotal report.
