Obsessive-Compulsive Disorder (OCD) is associated with recurrent intrusive thoughts and compulsive behaviors that can severely disrupt daily life. For patients who have not responded adequately to psychotherapy and medication, rTMS is one of the approved and promising pathways. To familiarize yourself with the basis of this method, also see the article What is rTMS?.

Why is OCD a candidate for rTMS?

Brain imaging studies have shown that OCD is associated with hyperactivity in circuits involving the orbitofrontal cortex and deeper brain structures. rTMS aims to modulate this hyperactivity by targeting these circuits.

The difference between the OCD protocol and depression

Unlike the standard depression protocol, rTMS for OCD often uses deeper coils (deep TMS) and different target areas to access the deeper circuits associated with obsession. To compare with its application in depression, read the article rTMS for treatment-resistant depression.

  • Patients seeking an option other than increasing medication dosage

What should be expected?

Similar to depression, the response is usually gradual and requires a complete course of sessions. rTMS typically does not replace behavioral therapy, but is used alongside it.

Summary for the patient

If your OCD has not responded adequately to standard treatments, rTMS is a scientifically validated option that targets specific brain circuits related to obsession — alongside behavioral therapy, not instead of it.
