title: Is it Parkinson's disease?
abstract: The diagnosis of idiopathic Parkinson's disease is based on clinical assessment and is also a diagnosis of exclusion. A number of neurodegenerative disorders have signs in common with Parkinson's disease and are referred to as parkinsonisms. The physical findings that help to make an early diagnosis of Parkinson's disease and the atypical features that make another disease more likely are presented.
