Overview
- The Lancet Psychiatry paper identifies six symptoms linked to later dementia: losing confidence, avoiding facing problems, lacking warmth or affection, feeling constantly nervous or tense, dissatisfaction with how tasks are done, and difficulty concentrating.
- These indicators carried risk levels comparable to established factors such as hearing loss and alcohol consumption.
- For people who reported these symptoms before age 60, the pattern fully explained the previously observed association between midlife depression and later dementia.
- The conclusions draw on 23 years of data analyzed by a University College London team and suggest potential warning signs up to about two decades before diagnosis.
- The study is observational, does not show causation, and the authors call for replication in larger, more diverse cohorts before changing clinical practice or introducing routine checks.
