Echocardiogram revealed diffuse hypokinesis, dilatation of left ventricular cavity, and thinning of left ventricular wall. Ejection fraction was decreased to 49%. Cardiac muscle biopsy demonstrated hypertrophied cardiomyocyte and interstitial fibrosis of left ventricle. A gastrocnemius muscle biopsy

✦ Synopsis
Abstract
We report on a 38‐year‐old patient with rapid‐onset dystonia–parkinsonism (RDP) with a missense mutation in the Na/K‐ATPase α3 subunit (ATP1A3). Asymmetrical parkinsonian symptoms evolved over a year. After a stable episode of another 2.5 years, overnight he developed oromandibular dystonia and more severe parkinsonian symptoms. We conclude that RDP should be considered as a rare cause of levodopa‐unresponsive parkinsonism even if there is no family history and the classic presentation is lacking. © 2005 Movement Disorder Society

## Abstract 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 dys
## Abstract Paroxysmal exercise‐induced dystonia (PED) is a rare, typically idiopathic familial condition, although sporadic and secondary cases have been reported. We present 2 cases where PED was the presenting feature of young‐onset idiopathic Parkinson's disease (PD), preceding the onset of par
## Abstract Pathogenic __PINK1__ mutations have been described in PARK6‐linked Parkinson's disease (PD) patients of Asian origin. However, data on the frequency of __PINK1__ mutations in sporadic early‐onset Parkinson's disease (EOPD) Asian patients are lacking. The objectives of this study were to
## Abstract The authors report a 7‐year follow‐up video study and molecular data on the Irish rapid‐onset dystonia–Parkinsonism kindred. All affected patients tested had a missense mutation in the Na^+^/K^+^ ‐ATPase α3 subunit (ATP1A3), twice previously identified, suggestive of a mutation hotspot.
