Deep Brain Stimulation shows promise for patients with chronic, treatment resistant Anorexia Nervosa
Date:3/6/2013

TORONTO In a world first, a team of researchers at the Krembil Neuroscience Centre and the University Health Network have shown that Deep Brain Stimulation (DBS) in patients with chronic, severe and treatment-resistant Anorexia Nervosa (anorexia) helps some patients achieve and maintain improvements in body weight, mood, and anxiety.

The results of this trial, entitled Deep Brain Stimulation of the Subcallosal Cingulate Area for Treatment-Refractory Anorexia Nervosa: A Phase I Pilot Trial, are published today in the medical journal The Lancet. The study is a collaboration between lead author Dr. Nir Lipsman a neurosurgery resident at the University of Toronto and PhD student at the Krembil Neuroscience Centre; Dr. Andres Lozano, a neurosurgeon, at the Krembil Neuroscience Centre of Toronto Western Hospital and a professor and chairman of neurosurgery at the University of Toronto, whose research lab was instrumental in conducting the DBS research; and Dr. Blake Woodside, medical director of Canada's largest eating disorders program at Toronto General Hospital and a professor of psychiatry at the University of Toronto.

The phase one safety trial investigated the procedure in six patients who would likely continue with a chronic illness and/or die a premature death because of the severity of their condition. The study's participants had an average age of 38, and a mean duration of illness of 18 years. In addition to the anorexia, all patients, except one, also suffered from psychiatric conditions such as major depressive disorder and obsessive-compulsive disorder. At the time of the study, all patients currently, or had previously, suffered multiple medical complications related to their anorexia altogether, the six patients had a history of close to 50 hospitalizations during their illnesses.

Study participants were treated with Deep Brain Stimulation (DBS), a neurosurgical procedure that moderates the activity of dysfunction
