Genetics of Response to ECT, TMS, Ketamine and Esketamine.

American journal of medical genetics. Part B, Neuropsychiatric genetics : the official publication of the International Society of Psychiatric Genetics June 17, 2025 Clio E Franklin, Murat Altinay, Kala Bailey et al. 2 citations

Treatment-resistant mood disorders are often managed with intensive interventions that include electroconvulsive therapy (ECT), transcranial magnetic stimulation (TMS), ketamine, and esketamine, but the role of genetics in clinical response to those interventions is yet to be clearly determined. Here, we review the current literature on the genetics of response to these treatment modalities. To...

MDMA and MDMA-Assisted Therapy.

The American journal of psychiatry 2025 Aaron Wolfgang, Gregory A. Fonzo, Joshua C. Gray et al. 47 citations

MDMA (i.e., 3,4-methylenedixoymethamphetamine), commonly known as "Ecstasy" or "Molly," has been used since the 1970s both in recreational and therapeutic settings. The Food and Drug Administration (FDA) designated MDMA-Assisted Therapy (MDMA-AT) as a Breakthrough Therapy for posttraumatic stress disorder (PTSD) in 2017, and the FDA is requiring an additional phase 3 trial after rejecting the...

Psilocybin: From Psychiatric Pariah to Perceived Panacea

American Journal of Psychiatry 2025 Adrienne Grzenda, Gregory A. Fonzo, Aaron Wolfgang et al. 14 citations

The evidence is currently insufficient to recommend psilocybin with PST as a psychiatric treatment. Additional rigorously designed clinical trials are needed to definitively establish efficacy in larger and more diverse samples, address dosing considerations, improve blinding, and provide information on mechanisms of action and moderators of clinical response. Head-to-head comparisons with...

Novel Pharmacologic and Other Somatic Treatment Approaches for Posttraumatic Stress Disorder in Adults: State of the Evidence.

The American journal of psychiatry December 1, 2024 Lauren M. Sippel, Jessica L. Hamblen, Benjamin Kelmendi et al. 11 citations

Posttraumatic stress disorder (PTSD) is a highly prevalent psychiatric disorder that can become chronic and debilitating when left untreated. The most commonly recommended first-line treatments for PTSD among adults are individual trauma-focused psychotherapies. Other evidence-based treatments include specific antidepressant medications and non-trauma-focused psychotherapies. Despite the...

Efficacy and safety of a 4-week course of repeated subcutaneous ketamine injections for treatment-resistant depression (KADS study): randomised double-blind active-controlled trial

British Journal of Psychiatry July 14, 2023 Colleen Loo, N. Glozier, David Barton et al. 70 citations

Background Prior trials suggest that intravenous racemic ketamine is a highly effective for treatment-resistant depression (TRD), but phase 3 trials of racemic ketamine are needed. Aims To assess the acute efficacy and safety of a 4-week course of subcutaneous racemic ketamine in participants with TRD. Trial registration: ACTRN12616001096448 at www.anzctr.org.au. Method This phase 3,...

Psychedelics and Psychedelic-Assisted Psychotherapy

FOCUS The Journal of Lifelong Learning in Psychiatry 2021 Collin Reiff, Elon E. Richman, Charles B. Nemeroff et al. 17 citations

Objective: The authors provide an evidenced-based summary of the literature on the clinical application of psychedelic drugs in psychiatric disorders. Methods: Searches of PubMed and PsycINFO via Ovid were conducted for articles in English, in peer-reviewed journals, reporting on “psilocybin,” “lysergic acid diethylamide,” “LSD,” “ayahuasca,” “3,4-methylenedioxymethamphetamine,” and “MDMA,” in...

A Consensus Statement on the Use of Ketamine in the Treatment of Mood Disorders

JAMA Psychiatry March 1, 2017 Gerard Sanacora, Mark A Frye, William M. Mcdonald et al. 577 citations

IMPORTANCE: Several studies now provide evidence of ketamine hydrochloride's ability to produce rapid and robust antidepressant effects in patients with mood and anxiety disorders that were previously resistant to treatment. Despite the relatively small sample sizes, lack of longer-term data on efficacy, and limited data on safety provided by these studies, they have led to increased use of...

Ketamine and Other NMDA Antagonists: Early Clinical Trials and Possible Mechanisms in Depression

American Journal of Psychiatry October 1, 2015 D. Jeffrey Newport, Linda L. Carpenter, William M. Mcdonald et al. 594 citations

OBJECTIVE: The authors conducted a systematic review and meta-analysis of ketamine and other N-methyl-d-aspartate (NMDA) receptor antagonists in the treatment of major depression. METHOD: Searches of MEDLINE, PsycINFO, and other databases were conducted for placebo-controlled, double-blind, randomized clinical trials of NMDA antagonists in the treatment of depression. Primary outcomes were...
