Brain cells meant to protect us may be fueling cognitive decline
Key Takeaways
  • Age-related cognitive decline is associated with dysfunction in oligodendrocytes, the brain cells that support neuronal insulation and health.
  • Dysfunctional oligodendrocytes alter myelin integrity and disrupt neural wiring, which can impair information processing across brain networks.
  • Targeting oligodendrocyte health and myelin maintenance could be a promising strategy to slow or prevent age-related cognitive decline.
