Memória verbal feminina pode atrasar diagnóstico de Alzheimer em anos

As mulheres mantêm pontuações normais em testes de memória padrão por quase três anos a mais que os homens, mesmo após o início das alterações cerebrais relacionadas ao Alzheimer. Essa vantagem cognitiva pode mascarar sinais precoces da doença e atrasar o tratamento. Uma nova análise de estudos de longo prazo nos EUA e no Canadá destaca a questão.

Pesquisadores liderados por Sasha Novozhilova, da Universidade McGill, examinaram dados de idosos que passaram por testes cognitivos regulares e exames cerebrais. Os participantes recordaram listas de 15 palavras em condições imediatas, tardias e com distração. Mulheres com acúmulo significativo de amiloide no cérebro continuaram a pontuar normalmente por uma média de 2,7 anos a mais do que homens com patologia comparável.

Small speech timing habits—such as silent pauses, “um” and “uh,” and difficulty finding words—were associated with performance on standard executive-function tests in a study by researchers at Baycrest, the University of Toronto and York University.

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.

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.

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.
