Summary
Ketamine therapy is often misinterpreted as a consciousness-expanding treatment, but its true function lies in promoting neuroplasticity as an NMDA receptor antagonist. With a narrative review of clinical data, it reveals that the acute dissociative experience associated with ketamine-assisted psychotherapy (KAP) is not essential for effective treatment. Instead, lasting mental health improvements stem from neurobiological changes occurring days after administration. Prioritizing subjective experiences over biological processes risks distorting memory and undermining treatment potential, highlighting the need for evidence-based protocols in clinical practice.
Abstract
In recent years, ketamine therapy has become increasingly entangled with psychedelic culture, leading to widespread misinterpretation of its therapeutic mechanism. This manuscript challenges the prevailing narrative that positions ketamine as a consciousness-expanding agent or psychotherapy enhancer, highlighting the discord between this view and ketamine's well-established neurobiological function as an N-methyl-D-aspartate (NMDA) receptor antagonist that promotes neuroplasticity. Drawing on recent research and clinical data, the article argues that the acute dissociative experience often emphasized in ketamine-assisted psychotherapy (KAP) is neither necessary nor sufficient for therapeutic success. Instead, it describes how meaningful, lasting improvement in mental health outcomes requires plasticity-driven reorganization in the days following ketamine administration, not from insights gleaned during dissociation. By prioritizing subjective experience over biological timing, current KAP practitioners risk distorting memory, reinforcing maladaptive narratives, and undermining the potential of psychoplastogenic treatments. This article calls for a shift toward evidence-based protocols that align clinical practice with neurophysiology, advocating for greater education, standardization, and scientific rigor in ketamine therapy.
