Mechanistic insights toward dissociating therapeutic from psychedelic effects: bridging the gap between psychedelic research and mental health care
Translational Psychiatry June 24, 2026 Mauro Pettorruso, Giacomo D’andrea, Antonio Inserra et al.
Emerging clinical and preclinical evidence suggests that the therapeutic benefits of psychedelics for depression and anxiety may be separable from their consciousness-altering effects. Psychedelics produce profound brain changes, including suppression of the default mode network, leading to intense subjective experiences such as ego dissolution. These effects require extensive preparation and integration, exclude individuals with certain psychiatric vulnerabilities, and raise scalability concerns. Pharmacological strategies like serotonin 2A receptor antagonism and development of biased psychedelic analogues might retain therapeutic efficacy without psychedelic experiences. Preclinical data indicate that downstream molecular and network-level mechanisms could mediate therapeutic effects independently of subjective states. Confirming this dissociation could enable more scalable, accessible treatments for broader psychiatric populations.
