Alzheimer’s is the most common cause of dementia, characterized by amyloid plaques and tau tangles in the brain. Risk factors: age (strongest), genetics (APOE4 gene), cardiovascular risk factors (hypertension, diabetes, obesity), physical inactivity, hearing loss (largest modifiable risk factor per Lancet Commission), depression, social isolation, and low education. The 12 modifiable risk factors account for approximately 40% of dementia cases. Early signs go beyond memory loss: difficulty with familiar tasks, language problems, disorientation, poor judgment, and personality changes. New treatments: lecanemab and donanemab (anti-amyloid antibodies) modestly slow progression in early Alzheimer’s. Prevention through lifestyle remains the most impactful strategy.
