Deep brain stimulation (DBS) is a surgical procedure that involves the implantation of a device called a neurostimulator, which sends electrical signals to specific areas of the brain. It is used to treat a variety of neurological and psychiatric conditions, including movement disorders such as Parkinson’s disease, essential tremor, and dystonia, as well as psychiatric conditions such as obsessive-compulsive disorder (OCD) and treatment-resistant depression.
During the procedure, a neurosurgeon implants electrodes into specific areas of the brain and connects them to a neurostimulator, which is usually placed under the skin in the chest or abdomen. The neurostimulator is programmed to deliver electrical stimulation to the brain through the electrodes at specific times and at specific levels of intensity.
DBS is generally considered to be a safe and effective treatment option for people with certain conditions that have not responded well to other treatments, such as medication or therapy. However, as with any surgical procedure, there are risks involved, including the possibility of infection, bleeding, and other complications. It is important for individuals considering DBS to discuss the potential risks and benefits with their healthcare provider and to carefully weigh their options before deciding whether to proceed with the procedure.
