Study Links ADHD to Higher Dementia Risk in Older Adults
Researchers found adults with ADHD had more than four times the risk of later cognitive impairment, and genetic risk was linked to a 35% higher chance.
- On October 7, 2026, University of Pittsburgh researcher Tharick Pascoal published a study in JAMA Psychiatry revealing adults with ADHD face significantly higher risk of cognitive impairment. The research followed 187,341 individuals aged 50 or older for an average of 10 years.
- Investigators combined electronic health records with ADHD polygenic risk scores to identify the association. Participants with highest genetic predisposition for ADHD were 35% more likely to develop cognitive impairment, independent of formal clinical diagnosis.
- Among participants, 6.7% of those with ADHD developed cognitive impairment compared to 3.4% without the condition. The diagnosis was associated with a more than four-fold higher hazard of cognitive impairment after accounting for age and sex.
- Patients managing both ADHD and cognitive impairment reported significantly worse mental health and social satisfaction. These individuals also utilized 20% more healthcare resources in the year following diagnosis, indicating substantial care burden.
- Experts urge regular cognitive monitoring for older adults with ADHD as a preventive measure. While the study does not establish causation, researchers emphasize that treatment and management of modifiable risk factors may support healthier cognitive aging.
