Despite the emergence of genetic and molecular approaches, disease categorization on the basis of clinical features remains an appealing approach, especially where the molecular mechanisms are poorly understood. A new study supports distinct clinical subtypes of Parkinson disease that could have implications for understanding the etiology of this condition.
