Washington: Older people can reduce their chances of getting dementia if they remain physically active, researchers say. In a new study, non-disabled people who regularly engaged in physical activity reduced their risk of vascular-related dementia by 40 percent and cognitive impairment of any etiology by 60 percent. The protective effect of regular physical activity remained regardless of age, education, changes in the brain’s white matter and even previous history of stroke or diabetes, researchers said.
