Comparing transcranial magnetic stimulation and esketamine treatment response trajectories in resistant depression.

Journal of Affective Disorders June 7, 2026 Lindsay L Benster, Jordan N Kohn, Benjamin Wade et al.

Repetitive transcranial magnetic stimulation (rTMS) and intranasal esketamine are FDA-approved for treatment-resistant depression (TRD), yet comparative real-world data on response trajectories and predictors of outcomes remain limited. A retrospective analysis was performed using electronic medical records from UC San Diego Health. Adults with TRD treated with rTMS (n = 279) or intranasal...

Efficacy of intranasal esketamine versus rTMS for treatment-resistant depression: analysis of individual participant data from two clinical trials.

EClinicalMedicine December 1, 2025 Tyler S Kaster, Yi Dai, Fidel Vila-Rodriguez et al. 5 citations

Repetitive transcranial magnetic stimulation (rTMS) and intranasal esketamine are effective treatment options for treatment-resistant depression (TRD) that have not been directly compared. We aimed to compare the effectiveness of rTMS, intranasal esketamine, and pharmacotherapy for TRD using data from two randomised clinical trials (RCTs). This secondary analysis of individual patient data...

Neurophysiological biomarkers of treatment response in suicidal ideation: a systematic review.

Translational Psychiatry November 17, 2025 Noah Stapper, Lindsay L Benster, Sahit Menon et al. 1 citation

Suicidal ideation (SI) is associated with increased morbidity and is one of the main modifiable risk factors for suicide. While initial evidence indicates the efficacy of several treatments for SI, most treatments were not developed to specifically target SI and are often associated with side effects or high relapse rates. Limited understanding of the neurophysiological basis of SI has hindered...

A Systematic Review of Study Design and Placebo Controls in Psychedelic Research.

Psychedelic Medicine March 12, 2024 Alexander Wen, Nikhita Singhal, Brett D. M. Jones et al. 36 citations

Introduction: Effective blinding is especially challenging in randomized controlled trials (RCTs) involving psychedelics due to the inherent alterations in consciousness that these compounds induce. In this systematic review and exploratory analysis, we aim at synthesizing the methodologies used in RCTs involving classic psychedelics and identify procedures that can help minimize unblinding and...

Management of Treatment-Resistant Depression: Challenges and Strategies

Neuropsychiatric Disease and Treatment 2020 Daphne Voineskos, Zafiris J Daskalakis, Daniel M. Blumberger 430 citations

Treatment-resistant depression (TRD) is a subset of Major Depressive Disorder which does not respond to traditional and first-line therapeutic options. There are several definitions and staging models of TRD and a consensus for each has not yet been established. However, in common for each model is the inadequate response to at least 2 trials of antidepressant pharmacotherapy. In this review, a...
