Anatomy of a Tremor: On the Molecular Basis of Parkinson's Disease

Anatomy of a Tremor

Perhaps a million people in the United States endure Parkinson's disease, which becomes increasingly common with age. Among neurodegenerative diseases, only Alzheimer's disease is more prevalent. The symptoms of Parkinson's disease, which include resting tremor, rigidity, slowed movement, and postural instability, can be controlled with drugs, but this approach becomes ineffective over time. Improved treatment of Parkinson's disease will likely require deeper understanding of the molecular events involved. Three leading researchers discussed this approach at a December 8, 2005, symposium of the New York Academy of Sciences' Neurodegenerative Diseases Discussion Group.
