Weaker Link Than Expected Between Exercise and Less Cognitive Decline

Previous research has tied increased physical activity with a lower risk of cognitive decline and dementia. But a recent meta-analysis involving 104 studies that included more than 341  000 participants suggested the association might be smaller than expected. The researchers did note in JAMA Network Open that even though the association was weak, it was still “significant in a population health perspective for the potential to postpone the multifactorial diseases causing deme ntia.”
