What do we know from clinical trials on exercise and Alzheimer's disease?

AbstractAlzheimer's disease (AD) is the most common form of dementia in elderly with major symptoms of a general term for memory loss and other intellectual abilities impairment which are serious enough to interfere with daily life. While there is no treatment can prevent and revise the cognitive function impairment in AD, physical activity becomes a potential beneficial intervention for AD. Multiple evidences suggested that exercise in general plays beneficial roles in improving brain function. Most common mechanisms of exercise-induced enhancement of brain function are including alteration of neurogenesis, neuron plasticity, neuronal signaling and receptors, as well as neuronal networks. This mini review includes most recent clinical studies and focuses on the effects of physical exercise, cognitive stimulation, and combination of both physical and cognitive training on protection and rescue cognitive decline in people with AD
