- The 'urge despite risk' construct provides a functional common denominator for OCD, addiction, and binge eating disorders.
- Intraoperative stimulation can provide immediate relief for movement disorders and diagnostic clues for psychiatric targets.
- Invasive epilepsy-style recordings (SEEG) offer a rigorous framework for identifying brain networks suitable for future non-invasive therapy.
- Machine learning models may eventually provide predictive 'early warnings' for impulsive or depressive episodes using multisensory physiological data.

Essentials: Compulsive Behaviors & Deep Brain Stimulation | Dr. Casey Halpern
This content explores the application of advanced neurosurgical techniques like deep brain stimulation and focused ultrasound to treat severe, refractory neuropsychiatric disorders such as OCD, addiction, and binge eating.
Key Takeaways
- Severe OCD and addiction are increasingly understood as circuit disorders involving the nucleus accumbens and prefrontal cortex.
- Stereotactic functional neurosurgery aims to interrupt pathological 'urge despite risk' loops in patients who fail traditional therapies.
- Future progress depends on using invasive human recordings to define precise neural targets for later non-invasive modulation.
