Whether these substances precipitate transient mood switches or contribute to persistent bipolar illness or diagnostic transition remains unclear. We conducted a...

Serotonergic psychedelics are re-emerging as therapeutic candidates across psychiatry, particularly for treatment-resistant depression. Their rapid and sustained antidepressant effects, alongside evidence for neuroplastic, dopaminergic, and glutamatergic modulation, have prompted interest in whether they could address depressive and negative symptoms in schizophrenia spectrum disorders (SSDs)....

While these effects are well described in healthy adults, little is known about their dynamics in clinical populations undergoing psychedelic-assisted psychotherapy. This retrospective, observational, single-center study analyzed...

Despite growing evidence supporting the efficacy of LSD-assisted psychotherapy in treating major depressive disorder (MDD), identifying reliable psychopharmacological biomarkers remains necessary. Oxytocin, a neuropeptide implicated in social bonding and flexibility, is a promising candidate due to its release following serotonergic psychedelic administration in healthy individuals; however,...

Introduction One of the main mechanisms of action of LSD in psychedelic-assisted psychotherapy (PAP) is the activation of 5HT2A receptors. This triggers a cascade of neurochemical processes with the release of neurotransmitters and neurohormonal substances. The release of oxytocin in this process is well documented in pre-clinical studies, with recent evidence in healthy subjects. We have no...
