TL;DR: Among Hispanic and Latino adults in the U.S., people with one particular DNA pattern around the APOE gene were more likely to show steep thinking decline over about 7 years. The well-known APOE4 risk version had a weaker link in the same group. Key Find…

TL;DR: A 2026 Molecular Psychiatry study tested Regional Vulnerability Index for Alzheimer’s disease (RVI-AD), a structural-MRI score of how closely a person’s brain pattern resembles amyloid-positive Alzheimer’s disease, and found that higher RVI-AD predicted…

Meat Intake Linked to Lower Dementia Risk in APOE4 Carriers TL;DR: In APOE4 carriers, higher total meat intake tracked with lower observed dementia risk over 15 years, while a higher processed-to-total meat ratio moved in the unfavorable direction. Key Finding…
