Deep Brain Stimulation is used primarily to treat which conditions?

Deep Brain Stimulation (DBS) is primarily used to treat some anxiety and mood disorders due to its ability to modulate brain activity and influence mood-regulating mechanisms. It involves the implantation of a device that sends electrical impulses to specific areas of the brain, which can help alleviate symptoms of disorders such as treatment-resistant depression and obsessive-compulsive disorder. The effectiveness of DBS in these cases has been supported by various clinical studies demonstrating significant improvements in patients' quality of life when other treatment options have failed.

While DBS has shown promise in the treatment of other conditions, such as certain movement disorders (like Parkinson's disease) and can have applications in chronic pain issues, its primary emphasis in the context of this question is its role in psychiatric conditions, particularly anxiety and mood disorders.
