A genetic predisposition to ADHD may increase risk for cognitive decline + Alzheimers disease, new research suggests.
have suggested a possible link between ADHD and Alzheimer's and other dementias. But exploring the association has been challenging because there are few large datasets on adults with ADHD.
At baseline, all participants underwent Aβ positron-emission tomography scanning, longitudinal cerebrospinal fluid phosphorylated tau at threonine 181 assessment, MRI, and a cognitive assessment. All returned at 6 months, 1 year, and annually thereafter. "Previous studies indicate that the effects of amyloid pathology in cognitive decline may depend on individual mechanisms of resilience and susceptibility," Laffe said.
Snyder emphasized that the findings"do not necessarily mean people with ADHD are at greater risk for cognitive decline. Larger, diverse population studies that further examine this possible association are needed."
