Exercise after brain injury: small study hints at cognitive benefits
NCT ID NCT07429526
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small pilot study looked at whether aerobic exercise can improve memory, attention, and fatigue in people who had a stroke or traumatic brain injury. Twelve participants were split into two groups: one did 30 minutes of aerobic exercise 3-4 times a week for 8 weeks, while the other continued their usual routine. The study used memory and attention tests, as well as brain scans, to measure any changes. The goal was to gather initial data to guide future, larger studies.
