Immature neurons looked different in people who stayed sharp past 80

What the research found
ScienceDaily reported on 27 October 2026 a Netherlands Institute for Neuroscience study in Cell Stem Cell. Donated brain tissue from the Netherlands Brain Bank was compared across people without detectable brain pathology, people who had Alzheimer’s dementia, and people whose brains showed Alzheimer’s pathology but who had stayed cognitively well. Immature neurons were still present at an average age over 80 in all three groups. The count difference was smaller than the team expected. In the resilient group, those cells showed more signs of survival programs and lower signals tied to inflammation and cell death. Sex was not reported. This is a tissue study, not proof that the brain is making new neurons or that any therapy produces resilience. Not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
