What is Subthalamic Nucleus deep brain stimulation?

Subthalamic nucleus deep brain stimulation refers to deep brain stimulation for Parkinson’s disease. There are two targets for deep brain stimulation for Parkinson’s disease, the subthalamic nucleus and the globus pallidus internus. Studies have shown that the two targets are equally effective for the treatment of Parkinson’s disease and the motor disorders of Parkinson’s disease. The difference is that subthalamic nucleus stimulation allows patients to reduce their medications more so than globus pallidus stimulation. However, the studies show that there seem to be an increase in the neurocognitive or psychological side effects of stimulation of the subthalamic nucleus.
