Deep brain stimulation (DBS) is one of the most invasive focal neuromodulation techniques available. It is being investigated for several psychiatric disorders, most notably treatment-resistant depression and treatment-refractory obsessive-compulsive disorder, but also Tourette’s Syndrome, Alzheimer’s dementia, and addiction. The rationale for using DBS in the treatment of psychiatric disorders is based on its effectiveness in several movement disorders and the development of detailed neuroanatomical models for regulating emotion, cognition, and behavior. Above, you can see a diagram* of a deep brain stimulation system. Electrodes are implanted via stereotactic neurosurgery and attached to an implanted pulse generator via subcutaneous extension wires.
