UK Parkinson's Disease Society Brain Bank Criteria for the Diagnosis of Parkinson's Disease
Supplemental for Parkinson's Disease (PD)
Short Description of Instrument

This instrument includes inclusion and exclusion criteria for diagnosing Parkinson's disease, as well as supportive diagnostic criteria. These criteria require verification of the occurrence of exclusion criteria and consideration of a parkinsonian syndrome other than PD before affirming a diagnosis of probable PD.


This instrument breaks the diagnosis of Parkinsonian syndrome into 3 steps. Step 1 is presence of bradykinesia and at least one of three other characteristic symptoms. Step 2 includes the exclusion criteria and Step 3 includes supportive prospective positive criteria, of which three or more are required for a diagnosis of definite Parkinson's disease.
