The effect of psilocybin on personality in patients with major depression -David Erritzoe

Over the last few years, a number of clinical pilot studies have examined the therapeutic potential of psilocybin for a variety of mental health conditions; including anxiety, OCD, smoking and alcohol dependence. David Erritzoe et al have recently
completed a similar feasibility study in treatment-resistant major depression. Based on previous observations in healthy psychedelic naïve volunteers of long-lasting increases in the personality trait “openness” after a single high-dose of psilocybin, Dr. Erritzoe et al speculated that similar changes in personality may occur in patients with major depression after their treatment with psilocybin. This talk will report on a clinical trial involving 19 pa-
tients with treatment-resistant depression who received two doses of psilocybin in an open label pilot study. Significant changes in personality traits, as assessed with pre- and post-treatment personality measurements using the full 240-item NEO-PIR, were observed. These data and their relationships with treatment response will be presented in this talk.
