“Cannabis may contribute to increased risk for mental disorders, which has actually been shown in schizophrenia,” Penzes said. “Conversely, cannabis could be beneficial in some brain disorders, which prompted trials of medical marijuana in patients with autism.”

Summary: Findings reveal a role the endocannabinoid system plays in a range of psychiatric disorders, including schizophrenia, bipolar disorder, and ASD.

Northwestern Medicine scientists discovered an unexpected connection between a synapse protein that has been implicated in neuropsychiatric disorders and the endocannabinoid pathway, according to a study published in Biological Psychiatry.

These findings suggest a role for the endocannabinoid system in conditions including bipolar disorder, according to Peter Penzes, PhD, the Ruth and Evelyn Dunbar Professor of Psychiatry and Behavioral Sciences, professor of Physiology and Pharmacology, and senior author of the study.
