Clinical findings in 196 patients with Parkinson's disease are reviewed and a subdivision of cases into an "equivalent" type (ART-type), akineto-rigid type (AR-type) and tremordominant type (T-type) of Parkinson's disease is introduced. Differences in the rate of progression and association with mental changes as well as in the predisposition for developing L-dopa induced dyskinesias have been observed between these subtypes of Parkinson's disease. The possible relation between tremordominant Parkinson's disease and essential tremor is also discussed.
