- What it is
- A patient-facing article from the U.S. National Library of Medicine's MedlinePlus Magazine on how Parkinson's disease is diagnosed and treated. It describes diagnosis as a clinical process built on history and examination, with no single confirming test.
- How much weight it carries
- Published by the U.S. National Library of Medicine, and reviewed for accuracy as a patient education piece. It is a summary for the public, so it does not give the details of diagnostic criteria, and it does not address research tools such as typing analysis.
