The effect of exercise on behavioural and psychological symptoms of dementia: towards a research agenda

Background: Behavioral and psychological symptoms of dementia (BPSD) are common and are core symptoms of the condition. They cause considerable distress to the person with dementia and their carers and predict early institutionalization and death. Historically, these symptoms have been managed with anxiolytic and antipsychotic medication. Although potentially effective, such medication has been used too widely and is associated with serious adverse side-effects and increased mortality. Consequently, there is a need to evaluate non-pharmacological therapies for behavioral and psychological symptoms in this population. One such therapy is physical activity, which has widespread health benefits. The aim of this review is to summarize the current findings of the efficacy of physical activity on BPSD.
