What does DBS mean in Physiology?

Deep brain stimulation

Deep brain stimulation is a surgical treatment involving the implantation of a medical device called a brain pacemaker which sends electrical impulses to specific parts of the brain. DBS in select brain regions has provided therapeutic benefits for otherwise treatment-resistant movement and affective disorders such as chronic pain, Parkinson's disease, tremor and dystonia. Despite the long history of DBS, its underlying principles and mechanisms are still not clear. DBS directly changes brain activity in a controlled manner, its effects are reversible and is one of only a few neurosurgical methods that allows blinded studies. The Food and Drug Administration approved DBS as a treatment for essential tremor in 1997, for Parkinson's disease in 2002, and dystonia in 2003. DBS is also routinely used to treat chronic pain and has been used to treat various affective disorders, including major depression. While DBS has proven helpful for some patients, there is potential for serious complications and side effects.
