About

The purpose of this research study is to test the safety and effectiveness of the study drug, Talampanel, when used to treat patients with involuntary movements known as dyskinesias, as a result of treatment to Parkinson's disease.

It is not clear why people with Parkinson's disease develop involuntary movements (dyskinesias) but studies show that blocking receptors in the brain for a chemical called glutamate decreases these movements. Talampanel is a drug which blocks these receptors.
