AbstractMultiple system atrophy (MSA) describes a relatively uncommon, debilitating disorder that is frequently misdiagnosed as Parkinson's disease. Patients with MSA show various combinations of parkinsonism, cerebellar ataxia, pyramidal signs and progressive autonomic failure, especially cardiovascular and urologic autonomic dysfunction. Few treatment options exist. Although some patients initially respond well to dopaminergic treatment for their parkinsonian symptoms, striatal degeneration occurs, and levodopa often becomes ineffective. Thus, physicians may provide only symptomatic treatment and support for patients with MSA. In this paper, we present a case study of a 68-year-old woman who came to the Vanderbilt Movement Disorders Clinic with severe autonomic dysfunction and parkinsonism, previously diagnosed as Parkinson's disease. Following autonomic function tests as well as clinical evaluation, she was diagnosed with MSA and began treatment for orthostatic hypotension and micturition dysfunction.
