About this trial
Repetitive transcranial magnetic stimulation (rTMS) is a FDA-approved treatment for depression and Obsessive Compulsive Disorder (OCD). The goal of the study is to learn how to optimize the treatment to improve symptoms of depression and OCD. This research project will test a new accelerated 5-day accelerated rTMS protocol for treating symptoms of depression and OCD.
A second goal of this study is to identify biomarkers of depression and OCD in the brain using functional magnetic resonance imaging (fMRI). This approach will predict who will benefit from TMS, determine the optimal treatment target, and improve treatment outcomes. Subjects will receive a clinical assessment of symptoms and an fMRI brain scan before and after each treatment course to measure the effect of treatment on symptom severity and on fMRI measures of functional connectivity.
Participants will be randomized to receive rTMS targeting either the lateral prefrontal cortex (LPFC) or the dorsomedial prefrontal cortex (DMPFC). Participants will complete a 5-day course of rTMS delivered hourly for 10 hours per day. Participants who show a partial response to treatment but not a full response will then receive a second 5-day course. Treatment non-responders will be crossed over to receive rTMS targeting the opposite brain area.
The primary hypothesis is that accelerated rTMS treatment will yield rapid improvement in symptoms for patients with depression and OCD in just 5 days, and that response rates can be further improved by adding a second 5-day treatment course.
Eligibility criteria
Qualifiers
Diagnosis of major depressive disorder OR obsessive-compulsive disorder (DSM-V criteria)
Hamilton Depression Rating Scale score greater than or equal to 18 OR Yale-Brown Obsessive-Compulsive Scale score greater than or equal to 16
Failed at least 1 prior trial of standard first-line treatment for depression or OCD per the modified Antidepressant Treatment History form and APA Practice Guidelines (e.g. serotonin reuptake inhibitor [SRI] or cognitive behavioral therapy with exposure and response prevention) OR had refused these treatments for individual reasons (e.g., cannot tolerate side effects, cannot tolerate exposure therapy, etc.).
Off antidepressants OR on a stable dose of antidepressants for greater than or equal to four weeks with plans to remain on this stable dose during the study Note: Medications that are known to increase cortical excitability (e.g., buprorion, 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.
Disqualifiers
Imminent risk of suicide (based on the CSSRS)
Presence of primary psychiatric diagnoses other than OCD, MDD and/or co-morbid GAD (ex. PTSD, MDD with psychotic features, primary psychotic illness, Bipolar I or II)
Evidence of cognitive impairment (MMSE score falling 1 SD below mean score for his/her age and education)
Evidence of psychotic symptoms on diagnostic interview (interfering with capacity to consent)
