Parkinson's Disease. Diagnostic Criteria. Differential Diagnosis

Abstract

Parkinson's disease (PD) is one of the most common neurodegenerative diseases. Disease diagnosis is based on generally accepted international clinical criteria. Currently, there are no research methods that confirm the diagnosis of PD. Degenerative diseases in early stages may mimic PD, however, some research methods can help recognize various forms of atypical parkinsonism. As the disease progresses, non-motor symptoms become the main sources of disability. Long-term observation and careful evaluation are the most important methods for making a correct diagnosis. The article presents the classification of parkinsonism and modern criteria for PD diagnosis. The sequence of diagnosis according to international standards is shown. Attention is paid to diseases accompanied by parkinsonism syndrome. Modern concepts of diagnostic research methods are presented.
