Parkinson's disease is defined as a chronic, degenerative, progressive disorder of the central nervous system that results from the reduction of a substance called "dopamine" in the brain and is usually seen in advanced age. The most basic symptoms include tremor in the hands at rest, generally more prominent on one side of the body, in a "pill-rolling" manner; slowed movement; stiffness and lack of arm movement while walking; blank gaze and reduced facial expressions resulting in what is described as "mask face"; and hypokinesia (decreased step length and speed, forward-leaning posture). Since the fundamental problem in Parkinson's disease is a neurotransmitter deficiency in the brain, patients generally respond well to medication therapy, and it is possible to treat a significant group of patients with medication in the early stages. However, in advanced stages of the disease, situations where medication therapy is insufficient are not uncommon.

Dystonia is a neurological disease characterized by muscle contractions in different parts of the body. The disease can be localized in the face, neck, vocal cords, arms, and legs, or can be widespread. Initially, it may manifest as deterioration in handwriting, cramps in the hands or feet, neck contractions, body twisting into unusual positions and gait disturbances, speech disorders, and uncontrolled blinking.

Essential tremor, one of the most common types of tremor, is a neurological disease that causes rhythmic trembling in various parts of the body. Unlike Parkinson's disease, in essential tremor, tremors occur when patients perform an action or task. Essential tremor disease is more prevalent compared to Parkinson's. While these tremor complaints can be seen in younger patients, nearly half of such cases have a familial characteristic; essentially, ET can be transmitted to children through heredity. Essential tremor is one of the most common movement disorders in the world and is 10 times more common than Parkinson's disease. When medical treatment becomes insufficient, Deep Brain Stimulation provides significant benefits for these patients.

The initial treatment for Parkinson's and all other movement disorder diseases is medication therapy. In cases where medication therapy is insufficient or severe medication side effects are experienced, deep brain stimulation therapy provides promising results.

Deep brain stimulation is a procedure in which devices that stimulate or suppress the electrical activity of brain cells in the stimulated area, by delivering electrical current to any point within the human brain.

Deep brain stimulation is successfully applied primarily for Parkinson's disease, as well as for tremor cases called "Essential Tremor" and "Dystonia" where excessive body contractions occur, in situations where medical treatment is insufficient.

These surgeries are performed while the patient is awake, talking, and even conversing with the doctors. Patients do not feel any pain or suffering during the surgery, other than the pain of anesthetic injections. The surgery is completed in approximately 3-3.5 hours.

Patients who were unable to tie their shoes, button their shirts, and were forced to a life dependent on others before treatment can return to their former healthy days and readapt to their social lives with Deep Brain Stimulation therapy.

There are no changes in the normal daily lives of patients who have had deep brain stimulation surgery. Patients can continue all kinds of sports activities that do not pose a risk for head trauma, such as tennis, billiards, swimming, and cycling.

Today, the Social Security System covers the entire cost of the device, which is the most expensive part of the operation, for appropriately selected patients operated under correct indications.
