Steps and lower dementia risk
Association of Daily Step Count and Intensity With Incident Dementia in 78 430 Adults Living in the UK
Quick answer
What this study found
Del Pozo Cruz et al. (2022, JAMA Neurology, PMID 36066874) followed 78,430 UK adults for about 7 years. The lowest dementia risk was seen at about 9,800 steps a day (49% lower), and about 3,800 steps a day captured half of that benefit. Steps taken at higher intensity showed stronger associations.

Kris's practical takeaway
Here's what to do with it.
Walking is brain training you can do on a phone call. Close to 10,000 steps was linked to the lowest dementia risk, and brisker steps showed stronger links.
