Study explains why some people's brains remain preserved with aging
NEW YORK - The condition of the brain deteriorates with aging in many people, as poor protein function leads to memory loss and cognitive properties, while in others the brain remains perfectly preserved, and the latest study has offered a potential explanation for this, reports the New York Times today.
TL;DR
- Older adults with preserved memory show significantly higher numbers of new neurons in the hippocampus compared to those with Alzheimer's.
- This preservation is attributed to active stem cell division and a genetic programming that sustains new neurons.
- The study proposes that Alzheimer's may involve disrupted neurogenesis, where stem cells are deactivated.
- This finding opens potential new therapeutic avenues for Alzheimer's by reactivating dormant stem cells.
- While promising, some researchers express caution regarding the study's methodology and call for validation through different techniques.
