Does deep brain stimulation work for bi-polar?

Deep brain stimulation (DBS) is primarily used for conditions like Parkinson’s disease and treatment-resistant depression, but its effectiveness for Bipolar disorder is still under research. Some studies suggest that DBS may help alleviate certain symptoms in patients with severe, treatment-resistant bipolar disorder, particularly depressive episodes. However, more extensive clinical trials are needed to establish its safety, efficacy, and the specific patient populations that might benefit from this treatment. As of now, it is not a standard treatment for bipolar disorder.
