Physical activity programs in older persons with Alzheimer's disease: a need for dedicated trials

Recent works highlight the influence of different aspects of lifestyle on cognitive decline and the risk of dementia. Some data suggest that exercise could improve cognitive performance, especially executive functions and reduce the risk of cognitive decline and dementia in the elder. There is controversial data regarding the role of physical exercise on cognitive performance in older patients with dementia, which may be due to diverse study designs. Innovative interventional trials need to adapt their aims toward physical and cognitive changes in patients suffering from Alzheimer's disease (AD) in association with physical activity (PA).
