Episode notes

The speaker discusses the two-hit hypothesis in understanding problems such as eating disorders.
The second hit can be devastating in the context of concussion literature.
Binging disorder is the most common eating disorder affecting 3-5% of the population and is likely under-diagnosed in obesity.

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.
