Long-term physical activity participation trajectories were associated with subsequent cognitive decline, risk of dementia and all-cause mortality among adults aged ≥50 years: a population-based cohort study

for middle-aged and older adults, both gradually improved and persistently active PA participation were associated with decelerated cognitive decline, lower risk of dementia and all-cause mortality. Strategies focusing on improving and maintaining PA participation could be of significance by attaining considerable neurocognitive and longevity benefits.
