Episode notes

There are disorders like depression, let's say, that I would describe as a bit more of a state disorder. Binging disorder or OCD or addiction and binging disorder in the context of obesity,. A lot of these patients are functioning quite normally every single day. It's just that intermittently throughout the day there's brief interruptions in their normal functions. And so we want to deliver a episodic therapy delivered at the right time to try to interrupted the circuit aberration"

My guest is Casey Halpern, M.D., Chief of Stereotactic and Functional Neurosurgery and Professor of Neurosurgery at the Perelman School of Medicine at the University of Pennsylvania. Dr. Halpern’s research and clinical practice focus on using deep brain stimulation to treat compulsive and movement disorders (e.g., binge eating disorders, bulimia, obsessive-compulsive disorder (OCD) and Parkinson’s disease essential tremor, dystonia). We discuss using deep brain stimulation to help patients who suffer from movement and compulsive disorders and applying this treatment to patients afflicted with binge eating. We also explore applications of this technology to other conditions such as OCD, anorexia and tremor, and the future therapeutic directions of the use of non-invasive brain stimulation approaches, including transcranial magnetic stimulation and ultrasound, for the treatment of other psychiatric illnesses and conditions. This episode will interest those curious about the biology of eating, anorexia, bulimia, compulsive thoughts and behaviors, and movement.
