A patient in a minimally conscious state plus received psilocybin, a classic psychedelic, for the first time. No increase in overt behavioral repertoire was observed on validated scales, but new spontaneous behavior not previously seen emerged, and brain complexity, measured by the Lempel-Ziv complexity index, increased with changes in underlying periodic rhythms. This case report contributes to future investigations of psychedelics for disorders of consciousness and the link between brain complexity and consciousness.
In three people with incomplete spinal cord injuries who self-medicated with psilocybin, improvements in motor function, muscle activation, and strength were reported. One person with a C4–C5 injury noted better gait automaticity; another with a T7 injury regained activation of a previously non-responsive hamstring muscle; a third with a T12 injury experienced rapid strength gains and enhanced proprioceptive awareness. All three reported psychological benefits such as increased wellbeing, motivation for recovery, and improved adjustment. Benefits appeared greatest in partially innervated muscles and diminished after stopping psilocybin. Temporary spasticity was the only adverse effect. The authors suggest psilocybin may enhance recovery by amplifying existing neural pathways and call for controlled clinical trials.
