Dementia risk more than quadruples among adults with common disorder

Key Points:

• A University of Pittsburgh study involving over 187,000 adults aged 50+ found that ADHD is associated with a significantly increased risk of dementia or mild cognitive impairment, with cognitive issues observed in 6.7% of those with ADHD versus 3.4% without.
• After adjusting for factors like age and health conditions, individuals with ADHD had more than four times the risk of cognitive impairment; those with the highest genetic susceptibility to ADHD had a 35% greater risk of dementia.
• Researchers caution that the study shows an association but does not prove causation, though the consistency of medical records and genetic data strengthens confidence in the link.
• Experts suggest difficulties with organization and healthcare management in people with ADHD may contribute to higher dementia risk, and emphasize the importance of lifestyle factors such as physical activity, diet, and managing chronic conditions to reduce overall risk.
• Individuals experiencing persistent memory, focus, or organizational problems are advised to seek professional evaluation to distinguish between ADHD symptoms and potential cognitive decline.
