[Clinical diagnostic criteria for multiple system atrophy].

What are the distinctive criteria for the diagnosis of multiple system atrophy? The combination of motor, dysautonomic, neuropsychological and eyes movements may help to distinguish, at a early stage, multiple system atrophy from other neurodegenerative diseases such as Parkinson's disease, progressive supranuclear palsy or corticobasal degeneration. Thus, these criteria are suitable both for clinical care and drug trials.
