We are often asked how we are sure that this is Parkinson's disease. Do you request additional medical tests?

The answer is that despite new developments in the field of Parkinson's, biomarkers and other clinical tests help with the diagnosis, mostly to confirm and/or exclude atypical cases, but clinical criteria, the evolution of the disease and response to basic medication (l-dopa) remain the basic parameters for establishing a diagnosis of the disease. Therefore advances such as genetic analysis, radiological tests (positron emission tomography (PET) and fluorodopa DATscan) help but are far from establishing a diagnosis.

The clinical evaluation and experience of the expert neurologist are the most specific and sensitive elements in the diagnosis and therapeutic orientation.
