  Deep Brain Stimulation
Deep brain stimulation (DBS) in adults is a one- or two-stage procedure under both local and general anesthesia.
Deep brain stimulation does not usually improve the "on" state (the patients best condition), but hopes to improve the patient when they are in their worst state.
The stimulators can be programmed in many different ways (the voltage, the frequency with which the stimulus is delivered to the brain, the length of each stimulus, and the shape of the stimulus and region that it influences the brain cells) and each patient may be different.

 What is DBS?
Deep brain stimulation (DBS) is a way to inactivate the thalamus, the subthalamic nucleus, or globus pallidus without purposefully destroying the brain.
Deep brain stimulation of the subthalamic nucleus is effective for all major symptoms of Parkinson's disease, such as tremor, slowness of movement, rigidity, and problems with walking and balance.
Deep brain stimulation of the globus pallidus is effective for a wide range of Parkinson's symptoms.

 Deep Brain Stimulation for Parkinson's Disease
Deep brain stimulation of the subthalamic nucleus is a procedure in which tiny electrodes are placed via computer guidance and physiological mapping into the subthalamic nucleus on each side of the brain.
Electrical stimulation of the subthalamic nucleus effectively jams or blocks the abnormal circuitry of the brain in Parkinson’s disease, thus minimizing many of the disabling symptoms and improving the overall quality of life of patients suffering from this degenerative disease.
Reduction of the amount of dopamine in the brain interferes with the normal brain circuitry involved in movement; in particular, areas of the brain known as the basal ganglia, thalamus, subthalamic nucleus and motor cortex.
