Aside from idiopathic Parkinson syndrome (Parkinson's disease), there are a number of other, so-called atypical parkinsonian syndromes: dementia with Lewy bodies (DLB), multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). DLB is a common disease, with a prevalence of 0.4% (400 cases per 100 000 persons) in the elderly; MSA and PSP both have a prevalence of 5 to 10 per 100 000 persons, while the prevalence of CBD is about 1 per 100 000. ⋯ Causal treatments for neurodegenerative diseases are now being developed and tested, and thus a molecular diagnosis is desirable. This will require the cooperation of primary care physicians with specialized centers.
