title: Phenomenological approach to the correct diagnosis of Parkinson's disease.
abstract: When dealing with movement disorders, it is helpful to first decide what phenomenon one is observing. Tremors can be differentiated from most other movement disorders and are further classified according to their frequency, and whether they are present at rest or with action. The parkinsonian syndrome can thus be identified correctly in most cases, and the etiology can usually be determined clinically. Correct diagnosis is the first step in correct treatment.
