Wanita mempertahankan skor normal pada tes ingatan standar hampir tiga tahun lebih lama daripada pria, bahkan setelah perubahan otak terkait Alzheimer mulai terjadi. Keunggulan kognitif ini dapat menutupi tanda-tanda awal penyakit tersebut dan menunda pengobatan. Analisis baru terhadap studi jangka panjang di AS dan Kanada menyoroti masalah ini.

Para peneliti yang dipimpin oleh Sasha Novozhilova di McGill University memeriksa data dari orang dewasa lanjut usia yang menjalani tes kognitif dan pemindaian otak secara berkala. Peserta diminta mengingat daftar 15 kata dalam kondisi segera, tertunda, dan terdistraksi. Wanita dengan penumpukan amiloid yang signifikan di otak mereka tetap mendapatkan skor normal rata-rata 2,7 tahun lebih lama daripada pria dengan patologi serupa.

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.

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.
