Cerebral small vessel disease and allostatic burden as mechanisms driving dementia risk in adults with ADHD
Summary
The purpose of this study is to learn about the brain health of people with attention-deficit/hyperactivity disorder (ADHD) as they age. Some people with ADHD may be at a higher risk for age-related problems, such as cognitive impairment or dementia, but it is unclear why. In this study, we will explore how brain health and physical stress impact cognitive health in adults. We will use brain scans, blood draws and physical measurements to measure vascular brain health and stress. We will use tests of thinking skills as a measure of cognitive health.
