Physical exercise as a non-pharmacological strategy for reducing behavioral and psychological symptoms in elderly with mild cognitive impairment and dementia: a systematic review of randomized clinical trials.

Moderate to intense aerobic and muscle strengthening exercises may have a potential benefit in the management of behavioral and psychological symptoms in dementia, but studies varied in their conclusions. This review indicates the need for further intervention studies to investigate, as a primary outcome, the absolute effect of physical exercise and its impact on behavioral and psychological symptoms in elderly people with MCI dementia, especially in the early stages of the disease.
