Deep brain stimulation (DBS) of the subthalamic nucleus is a neurosurgical intervention for Parkinson’s disease patients who no longer appropriately respond to drug treatments. A small fraction of patients will fail to respond to DBS, develop psychiatric and cognitive side-effects, or incur surgery-related complications such as infections and hemorrhagic events.

Patients with advanced Parkinson's disease who were treated with bilateral stimulation of the subthalamic nucleus had marked improvements over five years in motor function while off 2020-03-25 · Parkinson’s disease patients with implanted deep brain stimulators (DBS) in subthalamic nucleus (STN) provide a unique opportunity to investigate the role of the STN in anti-saccade behavior. 2017-04-01 · Deep brain stimulation of the subthalamic nucleus dramatically improves the cardinal motor symptoms of idiopathic Parkinson’s disease.

The subthalamic nucleus may play a modulatory role in the neural system for sequential working memory, which also includes the lateral prefrontal cortex. 2001-09-01 High-frequency deep brain stimulation (DBS) of the subthalamic nucleus (STN-HFS) is the preferred surgical treatment for advanced Parkinson's disease. In the 15 years since its introduction into clinical practice, many studies have reported on its benefits, drawbacks, and insufficiencies. The number of individual patients showing pathological autonomic test results at 1-year follow-up increased only in the subthalamic nucleus stimulation group. Despite reduced pharmacological treatment and reduced motor disability, bilateral subthalamic nucleus stimulation does not improve cardiovascular autonomic reflex function or protect against development of cardiovascular autonomic … 2001-01-01 Deep-brain stimulation of the subthalamic nucleus is an effective treatment for advanced Parkinson's disease, although evidence from randomised control trials is lacking. Electrical modulation of the subthalamic nucleus (STN) by deep brain stimulation (DBS) is effective for treating Parkinson disease (PD).1 However, the mechanism of action is not well understood.

Despite limited evidence-based data, STN-HFS has been shown to be surgically safe, and improvements in Objective To determine the postoperative attempted and completed suicide rates after subthalamic nucleus deep brain stimulation (STN-DBS) in a single-center cohort and to determine factors associated with attempted and completed suicide.

Abstract It is not known whether bilateral stimulation of the subthalamic nucleus, performed to improve skeletal motor control in advanced Parkinson's disease, also affects central autonomic regulation of cardiovascular motor function. Deep brain stimulation (DBS) for treatment of advanced Parkinson’s disease (PD) has two anatomical targets: the subthalamic nucleus (STN) and the globus pallidus internus (GPI). The clinical effectiveness of these two stimulation targets was compared in the present study. Parkinson's disease (PD) is characterized by the loss of dopamine (DA) cells in the substantia nigra pars compacta (SNc). The dopamine deficit leads to an increased activity of the output nuclei of the basal ganglia (BG), which could partly be explained by an increase of the excitatory drive from the subthalamic nucleus (STN).
