Attention-deficit/hyperactivity disorder (ADHD) appears to be somehow linked to risk of dementia and Alzheimer’s disease, a new multigenerational study has found.
Parents and grandparents of people with ADHD have a higher risk of Alzheimer’s and dementia than people with no ADHD in their family, Swedish researchers said.
Specifically, parents of an ADHD child have a 34% higher risk of dementia and 55% higher risk of Alzheimer’s, the results showed. Grandparents have about an 11% increased risk of either condition.
“ADHD is associated with dementia across generations,” said lead researcher Le Zhang, a doctoral candidate with the Karolinska Institute’s department of medical epidemiology and biostatistics, in Stockholm. “Our study calls attention to advancing the understanding of ADHD and cognitive decline in older age.”
However, it’s unclear what might tie the two conditions together, the researchers said.
