These indigenous people never suffer from dementia


  • In France, 1,227,558 people developed dementia in 2018.
  • In 2050, dementia will affect 3.31% of our population.

according to New studyPublished in the Journal of the Alzheimer’s Association, two indigenous groups have the lowest rates of dementia in the world.

Only one case between two music

Scientists from the University of Southern California have discovered that only 1% of Bolivians Tsimanes and Musétins, Bolivians who live in the Amazon rainforest, have dementia. By comparison, 11% of Americans age 65 or older have dementia.

To reach their conclusions, the team studied the brain condition of the Tsimanes and Moseténs using scanners and questionnaires. Of the 435 Tsimanes, researchers identified only five people over the age of 60 with dementia, and included only one case among the Mosetén. To their surprise, the researchers also found that Tsimanes and Mosetén with dementia often had unusual calcifications in the arteries buried in the skull.

Lots of physical activity

According to scientists, the low incidence of dementia in this population is due to their lifestyle. The Tsimanes and Mosetén already do a lot of physical activity through farming, hunting and fishing, and they have a very healthy diet, based on fruits, vegetables, meat and fish. They also do not suffer from air pollution.

It’s also clear that this quality of life pays off in other ways. Previous studies have shown that Tsimanes’ brains tend to age 70% less quickly than their Western counterparts. They also have significantly healthy hearts and the lowest prevalence of coronary atherosclerosis of any population.
