Ms. B is a 26 year old French teacher who was diagnosed with Obsessive Compulsive Disorder (OCD) at age 19. Since her diagnosis, she had tried multiple treatments in the United States, overseas and in Canada. However, none of these treatments improved her obsessions, which dominated her life, caused marked anxiety, and led to thoughts of suicide. She had left her work, and was living with her parents full time.

It was not until her family had heard of focused ultrasound at the Sunnybrook's Harquail Centre that things started to improve. With focused ultrasound (FUS) under MR imaging guidance, clinicians were able to more directly identify and develop personalized approaches to the treatment of her illness. These treatments are tailored to specific brain pathways, allowing clinicians to target regions involved, while preserving others.

Ms. B underwent the procedure and was discharged the following morning. Over a period of several months she began to see a gradual resolution of her obsessions. Today, her obsessions are almost entirely gone. She has resumed her job full time as a French teacher, and has applied for graduate work in the United States.
