This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing a treatment called repetitive transcranial magnetic stimulation (rTMS) — a non-invasive procedure that uses magnetic pulses to stimulate specific areas of the brain. The study focuses on people with obsessive-compulsive disorder (OCD) who have not gotten better with at least two different psychiatric medications. Researchers believe this magnetic stimulation might help reduce OCD symptoms by targeting the parts of the brain involved in obsessive and compulsive thoughts.
Many people with OCD don't respond well enough to standard medications, leaving them struggling with intrusive thoughts and repetitive behaviors that interfere with daily life. This trial exists to see whether this treatment might offer a new option for people whose OCD hasn't improved with conventional approaches.

If you are selected, you will receive magnetic brain stimulation sessions — two sessions per day for 10 consecutive days. Half of the participants will receive active treatment, while the other half will receive a placebo (sham) version that feels similar but delivers no actual stimulation; neither you nor the research team will know which group you're in until the study ends. Throughout the trial, you must keep your current OCD medications at the same dose and cannot start any new medications.
