Does exercise improve cognition in older adults? A meta-analysis of meta-analyses provides answers

Exercise may be an effective intervention for patients with mild cognitive impairment (MCI) and Alzheimer’s disease (AD), according to a recent review of meta-analyses.

According to Dr Patricia Heyn of the University of Colorado Anschutz Medical Campus in Aurora, Colorado, USA, numerous meta-analyses have been published on the effects of exercise on cognitive function in older adults. However, the quality of these reports can vary, and information of the overall outcome of these studies is lacking.
