Alzheimer’s disease doesn’t strike at random. While it’s not fully predictable, researchers have uncovered patterns—genetic, behavioral, and even psychological—that shape who is more likely to develop it.

First-degree relatives (parents, siblings) increase risk significantly Multiple affected relatives amplify that risk Shared genes, environments, and lifestyle habits all contribute One gene variant, APOE ε4 , is especially linked to increased risk. But even without genetic testing, family history remains a powerful clue. Personality Traits: A Surprising Predictor Recent studies show that certain personality traits may influence Alzheimer’s risk...
