Psychedelics Remodel Myelin to Heal PTSD
Neuroscience News • • health
Key Points:
- A new study reveals that psilocybin and MDMA aid long-term PTSD recovery by promoting myelin remodeling, repairing the brain’s insulating layer to restore synchronized neural circuit function beyond temporary psychedelic effects.
- Researchers demonstrated in a rat model that blocking myelin repair prevents the lasting anti-anxiety benefits of these drugs, highlighting oligodendrocytes—the myelin-producing cells—as crucial to sustained therapeutic outcomes.
- Both psychedelics also reduce astrocyte reactivity, lowering brain inflammation associated with chronic stress, suggesting a multifaceted mechanism involving structural brain repair and immune modulation.
- The findings suggest enhancing myelination could complement psychedelic-assisted therapy by stabilizing neural networks during recovery, potentially improving long-term treatment efficacy for PTSD and related
