A groundbreaking meta-analysis unveils a promising link: provoking symptoms before brain stimulation, specifically repetitive transcranial magnetic stimulation (rTMS), may significantly boost treatment outcomes for obsessive-compulsive disorder (OCD) and nicotine dependence. This research suggests that activating specific brain circuits before rTMS could nearly double its effectiveness.This innovative approach, detailed in the JAMA psychiatry study, highlights the potential of symptom provocation to enhance clinical responses, offering new hope for those struggling with these conditions.

Provoking Symptoms Before brain Stimulation Shows Promise for Treating OCD and Nicotine Dependence
Updated June 07, 2025
A meta-analysis published in JAMA Psychiatry indicates that symptom provocation could improve the effectiveness of repetitive transcranial magnetic stimulation (rTMS) for treating depression, obsessive-compulsive disorder (OCD), and nicotine dependence. Repetitive transcranial magnetic stimulation is a noninvasive brain stimulation method.
The study, led by dr. Heather Burrell Ward of Vanderbilt University Medical Center, investigated whether triggering symptoms before rTMS enhances treatment outcomes. their work represents the first large-scale analysis of this approach.
According to Ward, current FDA-approved protocols for OCD and nicotine dependence include symptom provocation before rTMS. Such as, someone with hygiene obsessions might touch a trash can before treatment. For nicotine dependence, a person might imagine smoking.
Ward said that while some evidence suggests activating a brain circuit before rTMS makes the treatment more effective, prior studies have been small. The meta-analysis aimed to provide more reliable results by combining data from multiple studies.
The analysis revealed that while symptom provocation did not significantly improve clinical response rTMS was nearly twice as effective when combined with symptom provocation. This suggests a potential benefit.
Ward noted the surprising consistency of this effect across OCD and nicotine dependence,despite differences in rTMS protocols,targets,and provocation methods.
She also suggested that symptom provocation’s effects might vary across populations. For instance, people with schizophrenia may not experience cigarette cravings when presented with smoking-related images, perhaps impacting the effectiveness of symptom provocation in treating nicotine dependence within this group.
“It was surprising to see that symptom provocation seemed to enhance clinical response for both OCD and nicotine dependence, despite different rTMS protocols, targets and provocation methods,” Ward said.
What’s next
Ward emphasized the need for prospective, randomized, controlled studies to directly assess whether symptom provocation improves response to rTMS. These studies should encompass OCD, nicotine dependence, other substance use disorders, and various rTMS targets to optimize rTMS treatment.
