What is Parkinson's Diseases ?
Parkinson's disease is a progressive degenerative disorder of the central nervous system, which is primarily caused by the loss of dopamine-producing brain cells. It is commonly diagnosed at advanced age. Early signs of Parkinson's disease include bradykinesia, stiffness, gait disorders, masking of facies (also known as hypomimia), and tremors in the form of "coin counting" or the sliding movement of the tips of the thumb and index finger over each other.
How Deep Brain Stimulation Treat Parkinson's Disease
Deep Brain Stimulation stimulate a targeted area in the brain by sending out electrical impulses that block abnormal neural activity. We can treat many types of movement disorders, primarily Parkinson's, thanks to this neuromodulation method.
Deep Brain Stimulation consist of a four-pole polarity reversing electrode, each made of platinum/iridium alloy, with an extension wire that connects the electrode to the neurostimulator and the body of the neurostimulator. The electrode is surgically inserted into the brain, and the extension wire bridges the electrode to the neurostimulator, which is placed below the collarbone. The neurostimulator can be remotely programmed to create different combinations (positive, negative and neuter) of the four poles at the tip of the electrode, thus changing polarity as necessary. We can adjust the amplitude, frequency (cycle/s) and wavelength of the signal in order to control the location and size of the target area in the brain.
Deep Brain Stimulation Surgery
Deep Brain Stimuation Surgeries are performed while the patient is awake, using only local anesthesia. Patients are given a general anesthetic only during the last hour of the operation, when the deep brain stimuation is placed below the collarbone. After the surgery, patients are scheduled follow-up appointments over the following weeks to fine-tune their pacemakers through computers, ensuring that they receive the best care. A deep brain stimulation is an easy and successful way to treat various types of movement disorders, including Parkinson's, as it is customized for the patient. It can also be controlled or removed if it produces adverse side effects.

The battery lasts on average five to eight years, depending on the targeted area in the brain and on the patient. Battery depletion does not require another brain surgery. The old battery, located below the collarbone, can be replaced in about 30 minutes. Deep Brain Stimulations that can be charged from the outside and with lifespans of up to 25 years can be used for dystonia patients, who require higher electric pulses. Deep Brain Stimulations do not affect one's daily life at all. Patients can engage in all kinds of sports, including swimming. Deep Brain Stimulation Patients are given a document stating that they have an implanted electronic device, so that they can pass through metal detectors without encountering any problems. Deep Brain Stimulation Patients are not allowed to get an MRI scan as it can change the deep brain stimulation's settings. If it is deemed extremely necessary, patients can undergo an MRI scan under the care of a specialist.
Deep Brain Stimulation & Social Security Institution
The Social Security Institution bears the full cost of the deep brain stimulation, the most expensive part of the surgery, for qualified patients with correct indications.
