STROKE survivors face an increased risk of dementia, but new research led by Monash University suggests exercise may help protect the brain.
Published in JAMA Network Open, the study involved 104 ischemic stroke survivors who began either an eight-week aerobic program or a balance and stretching program two months after their stroke.
Sessions were delivered via telehealth during the pandemic, with participants exercising three times a week.
After 12 months, both groups showed less brain shrinkage than typically seen in stroke survivors who do not exercise.
Those in the aerobic group also demonstrated stronger cognitive function, though brain volume was not preserved more than in the control group.
Lead researcher Professor Amy Brodtmann said stroke survivors need rehabilitation options similar to programs offered after heart attacks and cancer.
“Exercise may help preserve brain volume and cognition after stroke,” she said.
