title: The early diagnosis of Parkinson's disease.
abstract: Parkinson's disease is characterised by symptoms and signs which relate to tremor, rigidity and bradykinesis. The signs may be mild in the early stages of the disorder but the diagnosis can be established by careful neurological examination directed at proper evaluation of the essential features. The lack of any specific abnormality on special investigation leaves the responsibility for diagnosis with the clinician.
