Abstract

Physical activity is increasingly recognized as a key strategy for preserving cognitive function and reducing the risk of dementia in older adults. Evidence from longitudinal studies, randomized controlled trials, and meta-analyses indicates that multicomponent exercise programs—combining aerobic training with coordination, balance, and cognitive-motor tasks—enhance neuroplasticity, cerebral perfusion, and memory performance, thereby mitigating age-related cognitive decline and lowering the risk of Alzheimer’s disease. Aerobic exercise improves cardiovascular health and increases hippocampal volume, while coordination and balance exercises stimulate sensorimotor networks, executive function, and attention. Community-based and structured preventive programs, including group classes and individualized home routines, have demonstrated improvements in episodic memory, processing speed, and functional independence. This article synthesizes current scientific evidence and practical recommendations, emphasizing the integration of combined exercise modalities into daily life as an accessible, low-cost intervention to promote healthy brain aging and cognitive resilience in older adults.
