More women unrecorded with and are astatine higher hazard of processing dementia than men.

"Physical enactment has been identified arsenic 1 of the 3 astir promising ways to trim hazard of dementia and Alzheimer's disease. Prevention is important due to the fact that erstwhile dementia is diagnosed, it is precise hard to dilatory oregon reverse. There is nary cure," said LaCroix.

However, due to the fact that fewer ample studies person examined instrumentality measures of question and sitting successful narration to mild cognitive impairment and dementia, overmuch of the published probe connected the associations of carnal enactment and sedentary behaviour with cognitive diminution and dementia is based connected self-reported measures, said archetypal author, Steve Nguyen, Ph.D., M.P.H., postdoctoral student astatine the Herbert Wertheim School of Public Health.

"Older adults tin beryllium encouraged to summation question of astatine slightest mean strength and instrumentality much steps each time for a little hazard of mild cognitive impairment and dementia," said Nguyen.

"The findings for steps per time are peculiarly noteworthy due to the fact that steps are recorded by a assortment of wearable devices progressively worn by individuals and could beryllium readily adopted."

The authors said further probe is needed among ample divers populations that see men.
