What tests are used to differentiate Parkinson's disease from other similar conditions?

Expert neurologists describe the differential diagnosis process used to exclude other movement disorders that mimic Parkinson’s disease (PD). Unfortunately Parkinson’s disease can be challenging to diagnose because there is no simple test for Parkinson’s, and because it shares signs and symptoms with other conditions that affect the nervous system. The experts discuss imaging tests such as DaT scan or PET scan that determine if a person has low levels of dopamine, however these can’t differentiate whether a lack of dopamine is classical PD or a mimic of PD.
