Surgial Treatment of Parkinson's Disease
Parkinson’s disease is roughly characterized as a disease influencing deeply localized structures of brain and it accounts for a substantial part of symptoms of movement disorders. Movement disorder refers to tremor particularly in arms and legs, body stiffness and decrease in velocity of movements. Tremor leads to very severe and stressful life for the patient, while body stiffness and decrease in velocity of movements prevents independent mobility of patient.

Treatment of the disease involves medications and surgery. Principal active substance of medical treatment is dopamine. However, surgical treatment is performed if resistance occurs against drug in the length of time and drug-related movement disorder develops.
It should be kept in mind that surgical treatment of Parkinson’s disease is a matter of team work. Patient is necessarily examined by neurologist in pre-operative period and later, patient is referred to neurosurgeon for operation. Postoperative follow-up of the patient is undertaken by same team.
Battery can be activated approximately in postoperative day 3 or 4. Tuning of battery parameters is made in periodical visits throughout first several weeks in postoperative period and the final adjustment is made when optimum yield is obtained. Life of the battery is 5 years and there is no need to repeat electrode insertion into skull to replace battery. Only main battery compartment is opened and expired battery is removed and new battery is placed with a brief operation.
If patient is well eligible for operation, efficiency will range between 40 percent and 90 percent. The efficiency rate of 40 percent implies that a patient with inability to dress and undress without support may wear garments without any support. Very mild residual tremor in single hand of patient who experienced insufferable tremor in the part and attending control visits by walking with spouse in arm despite inability to walk without support of spouse due to stiffness are examples of priceless happiness for both patient and physician.
