An Amazon indigenous group whose brains age 70 per cent slower than those of Europeans could offer valuable insight into preventing dementia, scientists have said.

Researchers said the Tsimane indigenous people’s healthy diet and active lifestyle could explain the difference in brain decay compared to western populations.

They believe their findings may help scientists understand how to avoid Alzheimer's and dementia in later life.
