Research Discovery: Older adults who get ten minutes of daily exercise—even leisurely exercise, like taking walks—have better brain health than their sedentary peers.
Research Topic: Cognitive aging.
Key Findings: Of a study of 279 older adults without dementia, those who engaged in at least ten consecutive minutes of daily exercise had fewer lesions in the white matter brain tissue and performed better on tests of executive function.
What’s Next? Further research could improve upon this study’s precision, by accounting for differing “modes” of exercise, for example. In addition to preventing brain lesions, regular exercise improves cardiovascular health, which supports brain health.
Rowan Saloner (Next Generation Researcher, 2024) and Gil Rabinovici (Potamkin Prize recipient 2025) contributed to study finding that older adults who get as little as ten minutes of low-intensity exercise per day have healthier brains than sedentary peers.
