The goal of this clinical trial is to learn if individualized accelerated repetitive transcranial magnetic stimulation (rTMS) targeting the inferior frontal cortex combined with symptom provocation works to treat obsessive-compulsive disorders (OCD) in adults. It will also learn about the safety of rTMS over right IFC. The main questions it aims to answer are:
* Does rTMS using a new individualized IFC target relieve participants' OCD symptoms? * What medical problems do participants have when taking rTMS?
Participants will:
* Take rTMS six times per day for 5 consecutive days * Visit the clinic once at baseline, the day and four weeks after treatment for checkups and tests
