Modulation of Social Cognition via Hallucinogens and "Entactogens".

December 3, 2019 / Ayahuasca, LSD, MDMA, Mushrooms / Psilocybin, Papers, Psychology, Publications / By / ,

Abstract

Social cognition is a fundamental ability in human everyday lives. Deficits in social functioning also represent a core aspect of many psychiatric disorders. Yet, despite its significance, deficits in social cognition skills are insufficiently targeted by current treatments. Hallucinogens and entactogens have been shown to have the potential to modulate social processing. This article reviews the literature on the influence of hallucinogens and entactogens on social processing in controlled experimental studies in humans and elucidates the underlying neurobiological and neuropharmacological mechanisms. Furthermore, it identifies current knowledge gaps and derives implications for hallucinogen-assisted treatment approaches as well as the development of novel medication for trans-diagnostic impairments in social cognition.

Therapeutic use of serotoninergic hallucinogens: A review of the evidence and of the biological and psychological mechanisms.

Abstract

Serotoninergic hallucinogens include drugs such as lysergic acid diethylamide (LSD), dimethyltryptamine (DMT) and psilocybin. Recent trials with single/few doses of these compounds show that they induce rapid and sustained antidepressive, anxiolytic, and antiaddictive effects. These effects are also observed in religious groups using the DMT-containing brew ayahuasca. The agonist action of these substances on 5-HT2A receptors expressed in frontal and limbic areas increase glutamatergic transmission and neuroplasticity. These neurochemical effects are associated with acute alterations on self-perception and increases in introspection and positive mood, and with subacute and long-term decreases in psychiatric symptoms, increases in some personality traits such as openness, improvements in emotional processing, and increases in empathy. These are preliminary but promising results that should be further explored in controlled trials with larger sample sizes, especially considering that these compounds could be beneficial in the treatment of treatment-resistant psychiatric disorders.
