What this Trial Is About
Researchers are evaluating a new treatment approach for adults with Obsessive-Compulsive Disorder (OCD), a condition marked by unwanted repetitive thoughts and behaviors. This study aims to determine whether combining specialized inpatient care with repetitive Transcranial Magnetic Stimulation (rTMS) is feasible, well-tolerated, and effective. Two types of rTMS will be tested: deep TMS (dTMS) and intermittent theta burst stimulation (iTBS), using an accelerated protocol over two weeks. Participants will be randomly assigned to one of three groups: one group will receive dTMS plus Exposure and Response Prevention (ERP), another will receive iTBS plus ERP, and the third will receive ERP alone without rTMS. Both rTMS treatments involve four sessions per day, four days per week, totaling 32 sessions over two weeks. ERP therapy includes cognitive behavioral techniques, psychoeducation, and exposure exercises, with family involvement. The treatment occurs during a twelve-week hospitalization. During the study, participants complete questionnaires before, immediately after, and four weeks post-treatment. Brain imaging (MRI) and brain wave recordings (EEG) are done before and after treatment. Patients keep a daily diary of any side effects during rTMS. Researchers will monitor safety, feasibility, clinical outcomes, and brain changes related to treatment. Total participation lasts about ten weeks, integrated into usual inpatient care including medication and psychotherapy.

Your Study Journey
Duration - Up to 2 weeks before hospital admission
Participants are screened for eligibility to participate in the trial.
1 consultation visit including diagnostic interviews
Duration - 2 weeks
Participants are admitted to the inpatient OCD program and complete baseline assessments including questionnaires, MRI, and EEG before starting treatment.
Baseline imaging and questionnaire visits within hospitalization
Duration - 2 weeks
Participants receive standard inpatient care including Exposure and Response Prevention (ERP). Two groups additionally receive accelerated rTMS treatment (either deep TMS or intermittent theta burst stimulation) over a two-week period with four sessions per day, four days per week.
Multiple daily treatment sessions over 2 weeks plus daily adverse effect diary
Duration - A few days
Immediately after treatment, participants complete questionnaires and repeat MRI and EEG scans to assess treatment effects.
1 to 2 visits for post-treatment imaging and questionnaires
Duration - 4 weeks
Participants complete follow-up questionnaires assessing OCD symptoms and related measures approximately four weeks after treatment ends.
1 follow-up questionnaire visit
