Deep brain neurostimulator, also called brain pacemaker, is a device used for treatment of movement disorders. The movement disorders are commonly characterized by slowed down movements, involuntary contractions, uncontrolled tremor, difficulty in walking and muscle stiffness and they have devastating effects on quality of life.
Parkinson’s disease is the most widely known one of the movement disorders; essential tremor, dystonia and other rarer diseases fall into this group of diseases.Today, brain pacemaker is among the most effective treatment options for Parkinson’s disease.
Moreover, it can also be used in treatment of essential tremor, dystonia, tic disorders and epilepsy. Deep brain stimulation is the medical term used for the brain pacemaker.
A brain pacemaker consists of three parts; the stimulator, cables and battery. In the first phase of the treatment, cross-sectional images of the brain are obtained (CT and MRI) to determine location of the affected part of the brain precisely. CT and MRI images are combined and the resultant brain map is uploaded to the neuronavigation device.
The patient stays awake in the first phase of the surgery. Local anesthetic agent is administered to block the pain. The error rate is minimized by the use of advanced technologies, such as neuronavigation and neuromonitoring.
Electrodes are inserted into various parts of the brain tissue to check whether contraction, spasm, tremor and similar symptoms disappear. After the damaged part of the brain is precisely determined, electrodes are placed.In the second phase, anesthesia is administered and the battery of the device is placed into a pouch created under the clavicle.
Next, the electrodes placed inside the brain are connected to the battery with cables.Brain pacemaker implantation is a safe procedure and the risk rate is very low (1%).
The device is remotely accessed with a method similar to telemetry and the device settings are made. Patients live with the electrodes inside the brain in the rest of their lives and they are not replaced. The battery of the deep brain stimulator placed under the clavicle are replaced once every 5 years on average with a minor procedure.
Deep brain neurostimulation therapy has two aims: Alleviate symptoms of movement disorders and reduce dose or stop the medications used to manage the symptoms.The global hospital and physician network of Hera Healthcare allows you have access to all multidisciplinary diagnosis and treatment means available in Neurosurgery department.
