METHODS: One hundred and eighty-one parkinsonian patients were evaluated to determine if urogenital symptoms at presentation to the Neurology clinic can differentiate them as PD or MSA-P. An autonomic questionnaire was used to document urinary and genital symptoms. RESULTS: Mean age at presentation and disease duration in PD and MSA-P were similar. Urinary symptoms occurred twice as frequently in MSA-P than in PD. Storage symptoms (frequency, urgency, urge incontinence, nocturia) were common in both Parkinsonian disorders. Male MSA-P reported genital symptoms (erectile and ejaculatory failure) three times more frequently than in PD. CONCLUSIONS: Urogenital symptoms occurred in MSA-P when they had mild motor few symptoms unlike in PD where they occur when motor symptoms were severe. Urogenital dysfunction occurred early and was present in all MSA-P patients within two years. Presence of urogenital symptoms in early stages of Parkinsonism strongly favors MSA-P rather than PD. Absence of urogenital symptoms in advanced Parkinsonism makes MSA-P unlikely.
