Exercise-only interventions and exercise-based multidomain lifestyle interventions to promote cognitive function in older adults without dementia: a systematic review and meta-analysis.
British journal of sports medicine·September 21, 2026·PMID 42767813

This meta-analysis clarifies that exercise alone broadly improves cognition, while multidomain approaches may selectively enhance executive function and processing speed.
