Open-label, randomised Phase I trial (n=20) assessing safety and tolerability of single 25 mg or split 12.5 mg+12.5 mg oral psilocybin in people with chronic stroke; secondary outcomes explore motor recovery.
This Phase I study evaluates safety and tolerability of psilocybin administered as either a single 25 mg dose or a split 12.5 mg + 12.5 mg dose (second dose 2 hours later) in individuals at least 12 months post-ischemic or haemorrhagic stroke.
Secondary objectives include exploratory assessment of psilocybin's potential to enhance motor recovery after stroke, informed by preclinical data suggesting psychedelics may reopen critical periods for learning.
Single 25 mg oral psilocybin dose.
Split dose: 12.5 mg followed by 12.5 mg two hours later.
Second 12.5 mg given 2 hours after first.
