Improving Age-Related Cognitive Decline with Exercise in Hypertensive Older Adults

Description

The investigator aims to assess the extent to which a brief exercise intervention improves systemic growth factor concentrations, reverses loss of systemic vascular networks and hypertension, and by extension, improves neurocognition. To test the investigator's hypothesis that increased cardiovascular fitness will correlate with improved vascular density, the investigator proposes the innovative use of retinal density scans.
