Recent research from the University of Pittsburgh School of Medicine suggests ADHD—a common neurodevelopmental disorder—is associated with a higher risk of dementia. The study involved over 187,000 adults aged 50 and above and revealed a significant correlation between ADHD and cognitive decline.
Research Findings
The researchers utilized electronic health records and genetic data from participants in the U.S. National Institutes of Health All of Us Research Program. The study discovered cognitive impairment in 6.7% of those with ADHD compared to 3.4% of those without, indicating nearly a twofold increase.
Even after adjusting for factors like age, gender, and other health conditions, individuals with ADHD faced a risk more than four times higher. The findings, published in JAMA Psychiatry on October 7, only indicate an association, not causation.
“Seeing the same pattern independently in medical records and genes gives us greater confidence that the association isn’t simply how ADHD is diagnosed,” noted Tharick A. Pascoal, senior author and associate professor at Pitt.
Genetic predisposition to ADHD also raises dementia risk by 35%, according to research co-first author Guilherme Bauer-Negrini.
Understanding the Link
Dr. Elizabeth Landsverk, a geriatric medicine and dementia expert, observed that individuals with ADHD struggle with organization, potentially affecting their ability to manage health issues and increasing dementia risk.
Among people with ADHD, a 20% higher incidence of using health resources was noted. This complexity in managing healthcare could contribute to cognitive decline.
ADHD vs Dementia
Confusion arises as symptoms of ADHD and dementia may overlap, making differentiation challenging. Difficulty in managing daily tasks becomes a matter of concern.
“Changes in judgment, mood, or social behavior may be more suggestive of dementia,” Landsverk added.
Reducing the Risk
Despite the association identified in the study, lifestyle changes can potentially mitigate dementia risk. Maintaining a healthy weight alongside regular physical activity, avoiding smoking and excessive alcohol consumption, and controlling blood pressure and diabetes are crucial.
Landsverk recommends a largely plant-based diet and at least 30 minutes of daily exercise for overall well-being and focus enhancement.
Individuals facing persistent memory, focus, or organizational challenges should consult an expert for evaluation.
