What is Deep Brain Stimulation (DBS)
|First developed in France in the 1987, 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 remarkable therapeutic benefits for otherwise treatment-resistant movement and affective disorders such as Chronic pain, Parkinson’s disease, Tremor and Dystonia.|
After thorough examination, Doctors first will determine if the patient is a candidate for Deep Brain Stimulation Treatment. If the patient is found to be a right candidate then the doctor will review with you possible results before surgery. In this procedure, the surgeon implants a thin wire lead with four contacts (electrodes) at the tips into a specific area of your brain.
These electrodes are connected by wires to a type of pacemaker device (called an impulse generator, or IPG) implanted under the skin of the chest, below the collarbone. Once activated, the device sends continuous electrical pulses to the target areas in the brain, blocking the impulses that cause tremors ( involuntary movements and can affect the hands, arms, eyes, face, head, vocal cords, trunk, and legs). You control the generator, and you can turn it on or off when you swipe a special magnet over it.
To implant the electrodes, the neuro team fits the patient with a special head frame to keep the head still during the procedure (stereotactic head frame). Then, they use magnetic resonance imaging (MRI) to map your brain and identify the area in the brain where they’ll place the electrodes. They anesthetize your scalp before the procedure. During surgery, you’ll remain awake to report any side effects and talk to doctors while they place the electrodes. Your responses help your surgeon place the lead in the correct place while minimizing side effects. During surgery, your doctor carefully monitors your brain to help ensure correct electrode placement.
After the electrodes are implanted, you’ll receive general anesthesia so that you’re unconscious when your surgeon implants the generator in your chest and guides the wire lead from your brain to the generator.
After your surgery, doctors will perform an MRI to confirm correct placement of your device and leads. You may return to your normal activities after several days. The battery life of your generator varies with usage and settings. The battery should last about five years, if it’s used 16 hours a day. When the battery needs to be replaced, your surgeon will replace the generator during an outpatient procedure.
