CONDITIONS TREATED

Parkinson's Disease

Idiopathic Parkinson's disease occurs due to degeneration of the substantia nigra in the midbrain. Unfortunately , to date, there is no cure. The initial treatment of this condition is with medications. However, with the passage of time there is a relentless progression of symptoms despite the medical treatment. Also, there may be onset of side effects secondary to the medications, for example dyskinesias, which are uncontrollable, involuntary movements.

The most common operation currently being done at the HSC for the treatment of the symptoms of Parkinson's Disease is bilateral subthalamic nucleus stimulation. The intention is to help with multiple symptoms and to be able to reduce medications. Thalamotomy or DBS for the treatment of tremor only and Pallidotomy or DBS for the treatment of mainly dyskinesias are also available. Detailed pre-operative assessment is done prior to consideration for surgery as not all patients with Parkinson's are surgical candidates. It has been shown that careful patient selection affects success rates.

Also, careful consideration must be given of the potential risks and side effects of this type of surgery.
