Tsimane s brains experience less brain atrophy than Westerners as they age, indicates study
A team of international researchers has found that the Tsimane indigenous people of the Bolivian Amazon experience less brain atrophy than their American and European peers. The decrease in their brain volumes with age is 70% slower than in Western populations. Accelerated brain volume loss can be a sign of dementia.
The study was published May 26, 2021 in the
Journal of Gerontology, Series A: Biological Sciences and Medical Sciences.
