This 28-year-old Chinese man was referred for deep brain stimulation (DBS) evaluation for an 8-year history of refractory obsessive-compulsive disorder. After the patient had signed an informed consent, the authors implanted DBS leads. Hypomania with hypersexuality was noted on stimulation at Contact 2 and became aggravated with a higher voltage (≥ 3 V) during chronic bilateral DBS. After the voltage was decreased to 1 V, the patient's hypomanic symptoms subsided and his libido returned to baseline.
