NCT06919640

Brief Summary

This is an open-label, single-arm, pilot study exploring the neural, sensory, and cognitive effects of a single, medium dose of psilocybin in patients with chronic pain who already have implanted sensing-capable deep brain stimulation (DBS) devices. Outcomes include multi-site neural recording from previously placed ambulatory sensing-capable DBS devices, quantitative sensory and cognitive testing, and self-reports of pain. We hypothesize that psilocybin will change functional connectivity, decrease clinical and task-based pain reports, and improve cognitive functions.

Eligibility Criteria

Age21 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Currently implanted chronic brain sensing device (such as RC+S or Percept)
  • Not currently enrolled in another trial
  • Ability to speak and read English
  • Able to attend all in-person and virtual visits
  • No changes in medication or major surgical procedures anticipated for the trial
