A new study has found a potential link between attention deficit hyperactivity disorder (ADHD) and an increased risk of dementia or mild cognitive impairment. The research, led by the University of Pittsburgh School of Medicine, involved over 187,000 adults aged 50 and older who were enrolled in the U.S. National Institutes of Health's All of Us Research Program.
The study analyzed electronic health records and genetic information to examine the relationship between ADHD and cognitive impairment. The findings suggest that individuals with ADHD had nearly twice the rate of cognitive impairment compared to those without the disorder, with 6.7% of participants with ADHD experiencing cognitive impairment versus 3.4% of those without ADHD.
After adjusting for factors such as age, gender, and other health conditions, the researchers found that individuals with ADHD had more than four times the risk of dementia or mild cognitive impairment. The study also found that those with the highest genetic susceptibility to ADHD had a 35% greater risk of dementia than those with the lowest susceptibility.
The researchers noted that the study only shows an association between ADHD and dementia risk, and that more research is needed to determine the underlying causes of this link. However, the findings suggest that individuals with ADHD may be at increased risk of cognitive decline, particularly as they age.
Experts suggest that maintaining a healthy lifestyle, including a balanced diet, regular exercise, and managing health conditions such as blood pressure and diabetes, can help reduce the risk of dementia. They also recommend that individuals with ADHD prioritize their health and seek medical attention if they experience persistent problems with memory, focus, or managing everyday tasks.
