✓ Peer-reviewed alzhub usefulness score 76 out of 100. Prevention and risk

Topic: Risk, prevention and care in population studies

133 systematic reviews (2,724 RCTs and 258 279 participants) were included. Exercise significantly improved general cognition (SMD=0.42), memory (SMD=0.26) and executive function (SMD=0.24). Memory and executive function improvements from exercise were greater for children and adolescents than for adults and older adults. Those with attention-deficit/hyperactivity disorder exhibited greater improvement in executive function than other populations. Effects were generally larger for low- and moderate-intensity interventions. Shorter interventions (1-3 months) and exergames (video games that require physical movement) had the largest effects on general cognition and memory. Findings remained statistically significant after excluding reviews rated as low and critically low quality. These findings provide strong evidence that exercise, even light intensity, benefits general cognition, memory and executive function across all populations, reinforcing exercise as an essential, inclusive recommendation for optimising cognitive health. TRIAL REGISTRATION NUMBER: PROSPERO ID: CRD42023468991.

Key findings

Why it matters

This umbrella review found that exercise significantly improved general cognition, memory and executive function across all populations, including older adults. It provides strong evidence that exercise, even at light intensity, supports cognitive health, though memory and executive function gains were greater in children and adolescents than in adults and older adults.
