Essentials: Compulsive Behaviors & Deep Brain Stimulation | Dr. Casey Halpern

About this video

In this Essentials episode, neurosurgeon Dr. Casey Halpern explains deep brain stimulation and its expanding uses. Dr. Halpern describes DBS as implanting a thin wire to deliver electrical stimulation to a small brain region — a tool for delivering therapy in the form of electricity. He explains how stimulation can affect both motor circuits and nearby limbic circuits, which is why treating tremor in Parkinson’s patients sometimes also improves mood, compulsions or gambling. Dr. Halpern discusses efforts to identify ‘craving’ signals to treat binge eating and obsessive-compulsive disorder, and compares invasive DBS with non-invasive options such as transcranial magnetic stimulation and focused ultrasound. He emphasizes that scalable, rigorous solutions are still needed for problems affecting tens of millions.

Key takeaways

• Dr. Halpern describes deep brain stimulation as delivering electrical therapy through an implanted wire into a small brain region.
• Dr. Halpern explains that stimulation can affect limbic circuits near motor circuits, sometimes improving mood and compulsive behaviors.
• Dr. Halpern describes craving as the appetite analogue of tremor that his team tries to identify and modulate.
• Dr. Halpern notes transcranial magnetic stimulation is FDA-approved for depression, OCD and nicotine addiction, with effects that can be temporary.
• Dr. Halpern argues that non-invasive approaches should be embraced while acknowledging their precision still needs work.
