We systematically searched the CENTRAL, Medline, CINHAL, and...

Background: Bipolar II disorder (BD-II) is often associated with chronic and treatment resistant major depressive episodes. Psilocybin has shown promise for its rapid-acting antidepressant effects, though its impact on bipolar depression remains unexplored. In the present subgroup analysis of an already published trial on treatment-resistant depression (TRD), we aimed to preliminarily evaluate...

Abstract Psilocybin is a serotonergic psychedelic with therapeutic potential for treating mental illnesses 1–4 . At the cellular level, psychedelics induce structural neural plasticity 5,6 , exemplified by the drug-evoked growth and remodeling of dendritic spines in cortical pyramidal cells 7–9 . A key question is how these cellular modifications map onto cell type-specific circuits to produce...

There is a large and rapidly growing body of literature investigating the therapeutic effects of classic psychedelics in affective and anxiety disorders, but very few studies have examined the inverse of this, that is, the potential for psychedelics to inflict anxiety and affective symptoms. A systematic literature search was performed and 39 papers were included in the final review to...
