Christopher Wiegand, M.D Results from a Study of Psilocybin to Treat Obsessive-Compulsive Disorder in Human

Course Presenter(s):
Author(s): Christopher Wiegand, M.D. | (click author name for biography)

Course Description: This study investigated the safety, tolerability, and clinical effects of psilocybin, a potent serotonin agonist, in nine patients with Obsessive Compulsive Disorder (OCD). Subjects participated in up to 4 single-dose exposures to psilocybin, separated by at least 1 week, in doses ranging from sub-hallucinogenic to frankly hallucinogenic. Sessions lasted 8-hours in a controlled clinical environment, followed by overnight hospitalization. The Yale-Brown Obsessive Compulsive Scale (YBOCS) was administered at specific intervals, and vital signs monitored. Marked decreases in OCD symptoms were observed in all subjects during 1 or more of the testing sessions (23%- 100% decrease in YBOCS score) and generally lasted at least 24 hours. In a controlled clinical environment, psilocybin was safely used in subjects with OCD and was associated with acute reductions in core OCD symptoms in several subjects.

True/False Comprehension Quiz

Current OCD treatment with SSRIs (selective serotonin reuptake inhibitors) is only effective in 40 to 60% of OCD patients.
The results equivalent changes in OCD traits following sessions in which participants were given placebos instead of psilocybin.
The results Wiegand presents show significant adverse effects/events documented after 29 sessions with psilocybin.
Psilocybin is a potent activator at the serotonin 1A, 2A and 2C receptors involved in OCD.
