Scientists Discover “Immature” Brain Cells That May Defy Alzheimer’s

Researchers found rare immature neurons in very old human brains, including in people with Alzheimer’s pathology who never developed dementia.

In resilient individuals, these cells appeared to activate survival and anti-inflammatory pathways rather than simply increase in number.

The results point to a possible biological explanation for cognitive resilience despite Alzheimer’s changes.

The findings could help guide future treatments aimed at preserving brain function and protecting against dementia.
