Deep Brain Stimulation (DBS) is a neurosurgical procedure used to treat disabling neurological symptoms of Parkinson’s disease, essential tremor and dystonia that cannot be adequately controlled with medications.

DBS uses tiny electrodes surgically implanted to specific targets deep within the brain. The electrodes are connected by a wire just under the skin to a pulse generator implanted in the chest, beneath the collarbone. This painlessly provides electrical stimulation to the brain that helps control the symptoms. DBS leads are placed stereotactically using a 3D coordinated mapping system with neurological targets and intraoperative assessment by your neurologist to ensure the surgery is performed accurately.

DBS helps provide consistent therapeutic benefit, often relieving the on/off fluctuation of patients’ symptoms. This typically allows reduction in the dopamine based drugs including Levodopa, resulting in significant reduction in dyskinesias (excessive movements). Unfortunately DBS does not usually help with speech problems, freezing of gait, posture, balance, anxiety, depression or dementia.

Patients with advanced disease clinically or symptoms not adequately controlled by medications may be suitable for DBS. Potential patients are required to be assessed through a detailed multidisciplinary team assessment.

Dr Costello welcomes referrals to consult patients who are interested in and feel they may benefit from deep brain stimulation.
