Secret Brain-Cell Growth May Drive Superagers' Sharp Memories
TL;DR Summary
A study of 38 postmortem brains links exceptional memory in superagers to higher hippocampal neurogenesis, finding roughly twice as many immature neurons as in typical older adults; Alzheimer's groups show reduced immature neurons, while genetic data point to stronger synaptic plasticity and BDNF activity in superagers, suggesting neurogenesis as a driver of cognitive resilience and a potential therapeutic target.
