What We Do

The MRI-Guided rTMS Clinic is part of the Poul Hansen Family Centre for Depression​ and offers treatment for medically refractory major depression, anxiety disorders, eating disorders and obsessive-compulsive disorder, using a non-invasive form of brain stimulation known as repetitive transcranial magnetic stimulation, or rTMS.

The technique involves using powerful, focused magnetic field pulses to induce long-lasting increases or decreases in the activity of target brain regions. The magnetic stimulation is delivered under MRI guidance to ensure that the stimulation reaches the intended regions of the brain. Over 20 – 30 sessions of stimulation, rTMS can gradually correct underactivity or overactivity in regions of the brain that are involved in emotion regulation.

The MRI-Guided rTMS Clinic is a clinical research unit. We have an ongoing program of research trials, aimed at improving the effectiveness, cost and range of applications for rTMS. We also conduct basic research into the mechanisms of rTMS, using brain imaging to study how rTMS affects neural activity in psychiatric illness.

Over the last 5 years, rTMS at UHN has expanded to 4 stimulation suites and 18 full-time staff. As of October, 2015, the clinic has received over 1,6​00 community referrals and delivered over 20,000 sessions of stimulation. The clinic currently sees some 40 to 60 patients a day, making it one of the busiest in North America.
