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.
Although people in industrialized nations have access to modern medical care, they are more sedentary and eat a diet high in saturated fats. In contrast, the Tsimane have little or no access to health care but are extremely physically active and consume a high-fiber diet that includes vegetables, fish and lean meat.

COVID-19 Made it Clear We Need to Care for Caregivers
April 28, 2021USC
Before the COVID-19 pandemic, life was plenty busy for Jason Trujillo and his family.
He and his wife, Sherrie Jong, had two children, ages 4 and 1. Jong a civil engineer was the family’s breadwinner as Trujillo completed his first year at Southwestern Law School in Los Angeles. As the couple raised their family and juggled work and school, Jong’s parents, Engie and Monty, were getting older; 82-year-old Monty especially struggled to see and hear.
When they found out Monty had Alzheimer’s disease, the family knew he needed someone to care for him. That job fell to Trujillo. At first, he resented the stressful and unexpected role. But his mother helped him put things in perspective. “She said, ‘I didn’t raise you to leave an old man that needs help. Take care of this,’” he recalls. “She was 100% right.”
Brain changes in people with Alzheimer's disease and in those with mild traumatic brain injuries (TBIs) have significant similarities, a new USC study shows, suggesting new ways to identify patients at high risk for Alzheimer's.
