We report on a woman who had a severe sporadic nonprogressive dystonia-parkinsonism syndrome with rapid onset of symptoms at age 21. Secondary causes for dystonia were ruled out. No response to levodopa/carbidopa was seen. The patient fulfilled all diagnostic criteria of rapid-onset dystonia-parkinsonism, except for autosomal-dominant inheritance. Bilateral deep brain stimulation of the globus pallidus failed to alleviate her symptoms.
