NCT ID NCT07445841
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 4 times
Summary
This study tests whether starting a special exercise program soon after a stroke can protect the brain from memory loss and dementia. Researchers will enroll 120 people who had a stroke in the past 6 months. Participants will do a mix of exercises, and the study will measure changes in thinking skills and brain blood flow.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * medically stable * have had a first-ever ischemic/hemorrhagic stroke confirmed by MRI/CT 0-6 months prior to participation. * Able to independently walk at least 10 meters (assistive devices permitted) and capable of following instructions will be required. Exclusion Criteria: * Diagnosed with dementia * Medications that impact cognition * Absolute contraindications to exercise or MRI scanning * Significant disability (modified Rankin score \>3) * Participants will be excluded if they have been engaged in a structured exercise training program outside their regular in/out-patient hospital rehabilitation since suffering the stroke. * Co-morbidities that preclude exercise participation, pain worsened with exercise, and communication (e.g., severe aphasia) or behavioral issues limiting safe participation will also be reasons for exclusion.
