Key result
Physical activity in healthy older adults was associated with exercise-induced neuroplasticity and improvements in cognitive function across 9 studies.
Why the study?
Aging is associated with cognitive decline observable via EEG, and physical activity is considered a key strategy to promote health and prevent disease in older adults.
Does physical activity improve EEG activity and cognitive function in older adults?
Systematic Review (n=9)
Does physical activity improve EEG activity and cognitive function in older adults?
Physical activity promotes exercise-induced neuroplasticity, which underlies improvements in cognitive function in healthy older adults.
Supports physical activity for cognitive health in older adults; extends neuroplasticity evidence from systematic review.
Aging is generally associated with a decline in important cognitive functions that can be observed in EEG. Physical activity in older adults should be considered one of the main strategies to promote health and prevent disease in the elderly. The present study aimed to systematically review studies of EEG activity and cognitive function changes associated with physical activity in older adults. Records from PubMed, Scopus, and EBSCO databases were searched and, following the PRISMA guidelines, nine studies were included in the present systematic review. A risk of bias assessment was performed using the National Institute of Health Quality Assessment Tool for Case-control Studies instrument. The studies analyzed used two main strategies to determine the effects of physical activity on cognition and EEG: (1) multiscale entropy and power frequencies; and (2) event-related potentials. In terms of EEG activity, it can be concluded that exercise-induced neuroplasticity underlies improvements in cognitive function in healthy older adults.

Rodríguez–Serrano et al. (2024) conducted a systematic review in Cognitive decline in aging (n=9). Physical activity was evaluated on EEG activity and cognitive function changes. Physical activity in healthy older adults was associated with exercise-induced neuroplasticity and improvements in cognitive function across 9 studies.
