Psilocybin to reopen brain plasticity after chronic stroke

Psychedelic Healing: Adjunct Therapy Harnessing Opened Malleability

Phase 1 Interventional Johns Hopkins University · NCT07053917

This trial will test whether a supervised dose of psilocybin is safe and can help reopen brain plasticity in adults who had an ischemic or hemorrhagic stroke at least 12 months ago.

What this trial studies

This Phase 1 interventional study administers controlled psilocybin doses under clinical supervision to people with chronic ischemic or hemorrhagic stroke (≥12 months post-stroke) to measure safety and tolerability. Participants must follow medication and dietary restrictions and are monitored during and after dosing for adverse events, vital signs, and functional measures related to motor, language, and cognition. The protocol builds on preclinical and early human findings that certain psychedelics can reopen critical periods of brain plasticity and seeks to translate that effect to chronic stroke recovery. Findings from this study will determine whether larger trials testing efficacy are warranted.

Who should consider this trial

Good fit: Adults aged 18 or older with a confirmed ischemic or hemorrhagic stroke at least 12 months prior who can give informed consent, comply with medication and dietary restrictions, and arrange safe transportation after dosing.

Not a fit: People with strokes less than 12 months old, unstable medical or psychiatric conditions, inability to follow study restrictions, or who cannot avoid driving after dosing are unlikely to receive benefit from this protocol.

Why it matters

Potential benefit: If successful, psilocybin could restore a window of brain plasticity that helps people regain motor, language, or cognitive skills long after a stroke.

How similar studies have performed: Preclinical and early human work indicates psychedelics can reopen plasticity windows, but applying psilocybin specifically to improve chronic stroke recovery in patients is largely untested.
