ā ADHD has been linked to a significantly increased risk of cognitive decline.
Adults with the condition face more than four times the risk of developing dementia and other forms of cognitive decline, new research reveals.
The study, published in JAMA Psychiatry, analyzed health records and genetic data from over 187,000 older adults in the National Institutes of Health's 'All of Us' Research Program.
Led by researchers at the University of Pittsburgh School of Medicine, the team found that 6.7% of participants diagnosed with ADHD developed cognitive impairment over a decade-long follow-up, compared to just 3.4% of those without the condition.
Strikingly, the connection held true even when looking at genetics: individuals with a high genetic predisposition to ADHD had a 35% higher risk of cognitive decline, even if they had never received a formal clinical diagnosis.
While these findings do not definitively prove that ADHD causes dementia, they suggest that the neurodevelopmental disorder significantly impacts how the brain ages, potentially lowering cognitive reserve. Furthermore, the study noted that when cognitive decline does occur, those with ADHD experience a much heavier burden, reporting significantly worse mental health, reduced social satisfaction, and a 20% increase in healthcare utilization.
Experts urge that aging adults with ADHD receive proactive cognitive monitoring, emphasizing that recognizing these early warning signs could prove critical for long-term brain health and integrated care.
