The symptoms of each of the four atypical parkinsonisms are reviewed in the “Symptoms” section of the page dedicated to that disorder. Use the links below to connect to “Symptoms”.

Generally, symptoms of these disorders are a combination of parkinsonism (e.g. bradykinesia, rigidity, and postural instability) and dementia (memory and thinking skills). Sometimes, one category of symptoms (e.g. dementia in MSA) is entirely missing.
