Investigating Midlife Physical Activity and Cognition Trial: Observational Study (IMPACT- Obs)
Summary
This study will look at how everyday physical activity levels relate to thinking and memory in 200 adults aged 45–59 with a family history of dementia. You will wear a small activity watch on your wrist for seven days to track your daily movement and sedentary behaviour (like sleep). During a lab visit, you will do some thinking and memory tests, where brain activity and brain blood flow will be measured using sensors placed over your head. Blood and stool samples will also be collected. We also want to see how your stress axis functioning may be related to your level of physical activity and how it is involved in how your brain works. In order to look at stress axis functioning, you will collect 5 saliva samples at specific times over two consecutive days. During the lab visit, you will also take part in a game that is known to temporarily and mildly increase stress. We will see whether these links between the brain, physical activity, and blood/stool/stress differ for females and males and across menopause stages for females. This is not an exercise program, rather we will observe your usual movement. Our goal is to learn if and how daily movement supports brain health in midlife so people can act early, before memory problems begin.
