Exercise at One Stage of Life May Cut Dementia Risk by Up to 45% : ScienceAlert https://share.google/j97bsFXvg8rDGBJ7i
This was a huge study, over generations, and it demonstrates a clear trend: 'The findings largely reinforce what scientists already know: exercise is good for the brain.
When researchers examined physical activity levels, the pattern was striking. Those with the highest levels of activity in midlife and later life were 41–45% less likely to develop dementia than those who had the lowest levels of activity.
What sets this study apart is its large sample, multi-decade follow-up, and its genetic analysis across different life periods.
The suggestion that midlife activity benefits some individuals differently depending on their genetic risk, while late-life activity benefits nearly everyone, may also add a new layer to public health messaging.'
For years, scientists have known that moving our bodies can sharpen our minds.
