A new study reveals that exposure and response prevention (EX/RP), a primary therapy for obsessive-compulsive disorder (OCD), effectively reshapes brain connectivity. This therapy enhances cognitive control by strengthening connections within key neural networks. Using advanced MRI techniques, researchers observed significant changes in the frontoparietal, cingulo-opercular, and default mode networks among OCD patients who underwent EX/RP compared to those who received stress management training.
