Individualized Neuroimaging Biomarkers for Predicting rTMS Response in OCD
Individualized Neuroimaging Biomarkers for Predicting Repetitive Transcranial Magnetic Stimulation (rTMS) Response in Obsessive Compulsive Disorder (OCD)

Intervention / Treatment
Detailed Description
New interventions are urgently needed to treat obsessive compulsive disorder (OCD), as more than 25% of patients show no improvement with the standard of care. Repetitive transcranial magnetic stimulation (rTMS) is a promising alternative treatment, as it uses focused magnetic field pulses to stimulate specific brain areas. So far, medial and right prefrontal cortex stimulation targets have consistent evidence of efficacy in OCD. Patients often show a strong response to one target but not the other. It is not well understood why some patients respond, while others do not. So far, there are no biomarkers for predicting treatment response, identifying the optimal neuroanatomical target, or choosing between treatments.
The goal of this clinical trial is OCD subtype discovery and treatment optimization. Using MRI scans of OCD patients before and after rTMS treatment we aim to:
- Define novel network-based subtypes of OCD that can be diagnosed in individual patients and differentiated from healthy controls;
- Identify characteristic functional connectivity profiles predictive of response to MPFC-rTMS versus rPFC-rTMS;
- Identify characteristic changes in resting-state functional connectivity (RSFC) associated with symptom improvement for OCD patients undergoing MPFC- and rPFC-rTMS.

a. Medications that are known to increase cortical excitability (e.g., bupropion, maprotiline, tricyclic antidepressants, classical antipsychotics) or to have an inhibitory effect on brain excitability (e.g., anticonvulsants, benzodiazepines, and atypical antipsychotics), or any other medications with relative hazard for use in TMS will be allowed upon review of medications and/or motor threshold determination by TMS specialist.
- Failed at least 1 prior trial of standard first-line OCD treatment per APA Practice Guidelines (serotonin reuptake inhibitor [SRI] or cognitive behavioral therapy with exposure and response prevention) OR had refused these treatments for individual reasons.
