science 💡 Stress hormone might actually help brain repair
New research indicates that corticotropin-releasing hormone (CRH), linked to stress, could aid brain myelin repair after injury. Researchers at the Max Planck Institute of Psychiatry found CRH triggers a repair mechanism in the brain following damage. The study noted this CRH response appears within hours of injury but subsides after about three days. This suggests the stress system might act as an early emergency signal for brain damage. Clinically, this reframes myelin as actively tuned by stress signaling across the lifespan. 🧠
