At age 27, she developed right\u2010sided parkinsonism. Exertional paresis and dystonia and parkinsonism responded completely to levodopa; however, she developed a progressive reduction in the duration of action of levodopa over the first 4 years of treatment. Investigations including computed tomography, magnetic resonance imaging, [<jats:sup>18<\/jats:sup>F]fluorodopa, and [<jats:sup>18<\/jats:sup>F]fluorodeoxyglucose positron emission tomography scans suggested a static lesion involving the left substantia nigra. This unusual exertion\u2010induced weakness and hypotonia alternating with hypertonia and dystonia has not been reported previously. The role of dopamine deficiency in dystonia and the role of levodopa in the development of fluctuations in Parkinson's disease are discussed. Review of the literature, including this patient, emphasizes the heterogeneity of the syndrome of hemiparkinsonism\u2010hemiatrophy.<\/jats:p>","DOI":"10.1002\/mds.870100414","type":"journal-article","created":{"date-parts":[[2004,12,31]],"date-time":"2004-12-31T09:42:22Z","timestamp":1104486142000},"page":"489-495","source":"Crossref","is-referenced-by-count":18,"title":["Hemiatrophy,
