Overview
Studies suggests that low educational attainment, physical inactivity, and social isolation are associated with increased risk for cognitive decline and dementia. Also higher levels of education along with cognitive and social activity produce a cognitive reserve that decreases the impact of neurodegeneration on cognitive function.[1] The stress hypothesis suggests that active individuals have more positive emotional states and reduced stress, leading to a lower susceptibility to dementia. Individuals with higher levels of education may show less cognitive decline or delayed development of clinical dementia compared with those with lower levels of education[2]
