A scoping review protocol describes a plan to systematically map the existing literature on psychedelic drugs as modulators of social cognition in patients with psychiatric and neurodevelopmental disorders. The protocol follows JBI Scoping Review Methodology Group guidelines and will search MEDLINE, PsycINFO, EMBASE, and Scopus, with two-stage screening by two independent reviewers. The goal is to identify what is currently known and any gaps in the literature, potentially leading to new treatments for social cognition defects in clinical populations.

A review of 20 studies examined whether psychedelic drugs can affect social cognition in people with psychiatric or neurodevelopmental disorders that involve cognitive impairment. The drugs studied were ketamine, MDMA, psilocybin, LSD, and ayahuasca, tested in depressive disorders, anxiety disorders, autism spectrum disorder, and post-traumatic stress disorder. Findings included neural activation patterns suggesting that ketamine and psilocybin may modulate processes relevant to social perception, especially facial emotion processing, in depressive disorders. MDMA was linked to improvements in self-reported psychosocial functioning, self-awareness, and self-compassion in participants with PTSD. Direct evidence of improved social-cognitive functioning remains limited.
