[Atypical Parkinson syndromes--recent advances in diagnosis and therapy].

The term "atypical Parkinson syndromes" usually encompasses the following diseases: multiple system atrophy (MSA), progressive supranuclear palsy (PSP) and corticobasal syndrome (CBS). The differential diagnosis is still a challenge even for a movement disorders specialist, not least because of the distinct therapeutic approaches and disease prognosis. The aim of this review is to provide an overview of current diagnostic criteria and therapeutic approaches and to cite recent findings from clinical and experimental studies.
