Kvinnors verbala minnesförmåga kan fördröja Alzheimers-diagnos med flera år

Svenska

Kvinnor upprätthåller normala resultat på standardiserade minnestester i nästan tre år längre än män, även efter att Alzheimers-relaterade hjärnförändringar har börjat. Denna kognitiva fördel kan dölja tidiga tecken på sjukdomen och fördröja behandling. En ny analys av långtidsstudier i USA och Kanada belyser problemet.

Forskare ledda av Sasha Novozhilova vid McGill University har granskat data från äldre vuxna som genomgått regelbundna kognitiva tester och hjärnavbildningar. Deltagarna fick återge listor med 15 ord vid omedelbara, fördröjda och störda förhållanden. Kvinnor med betydande amyloidansamlingar i hjärnan fortsatte att prestera normalt i genomsnitt 2,7 år längre än män med jämförbar patologi.

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.

Study finds lower normal B12 levels tied to brain changes

A University of California San Francisco study has linked lower but still normal levels of active vitamin B12 to slower thinking and white matter damage in healthy older adults. The research, published in Annals of Neurology in 2025, suggests current guidelines may miss early neurological risks. Researchers examined 231 participants with an average age of 71.

Severe infections raise dementia risk in large Finnish study

Rapporterad av AI

A study of over 375,000 Finns has linked hospital treatment for severe infections like cystitis and pneumonia to a higher risk of developing dementia within five to six years. Researchers identified 29 conditions associated with at least a 20 percent increased risk, with infections playing a key role. The findings suggest that preventing such infections could help modify dementia risk.
