I'm curious about the day to day environment the Tsimané live in since I can see a relationship between dementia and increased accidental deaths in more dangerous environments. Let's say you need to walk 5 miles a day through a predator infested jungle for water. Getting lost one day due to an episode of dementia could easily kill you. Same for eating a poisonous plant or drinking water from the wrong source or even getting a simple cut that becomes infected due not paying attention. The study used 65 as a cutoff which is before most physical deteriorations so individuals are likely still self-reliant.
