rTMS is primarily used to treat major depressive disorder (MDD) in individuals who have not responded to medications or therapy (treatment-resistant depression). It’s also being studied and used for various other conditions including anxiety disorders (such as Generalized Anxiety Disorder (GAD)), obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), tinnitus, and certain chronic pain conditions like fibromyalgia. The effectiveness can vary depending on the individual and the specific condition being treated.
