Ketamine-induced altered states of consciousness: a systematic review of implications for therapeutic outcomes in psychiatric practices.

This systematic review aims to elucidate the nexus between ketamine's psychoactive properties and its efficacy in treating a broad spectrum of psychiatric disorders. We searched three databases and used citation tracking to include 29 studies. Predominantly, mood disorders, including bipolar disorder (BD) and major depressive disorder (MDD) (MDD + BD: + n = 25 studies), a large part of them involve treatment-resistant patients (n = 14 studies), substance use disorder (SUD, n = 3 studies), and social anxiety disorder (SAD, n = 1 study).

Methods: Sixty-two adult men (mean age: 31.
