Deep Brain Stimulation

As a neurosurgeon at Cleveland Clinic Florida, Dr. Badih Adada provides treatment for a wide variety of brain and spinal cord disorders. Dr. Badih Adada has performed a number of brain stimulation treatments, which address the symptoms of Parkinson’s disease.

Designed to alleviate the involuntary and inhibited movements that characterize Parkinson’s disease, deep brain stimulation renders certain aspects of the brain inactive. To perform the procedure, a surgeon must first identify those areas of the brain that are causing the patient’s symptoms. The US Food and Drug Administration has to date approved three targets, the most common of which are the subthalamic nucleus (STN) and the globus pallidus interna (GPi). Research suggests that the GPi may provide a safer target for preservation of cognition and language, though the STN has proved most successful in reducing medication levels.

Once the neurosurgeon has identified the target for a particular patient, that surgeon will surgically introduce an insulated wire known as an electrode through the skull and place the tip inside the targeted area. An extension wire connects the electrode to an implanted neurostimulator, most commonly located under the patient’s collarbone. This system sends electrical signals that can block tremor-inducing signals without removing brain tissue.
