A family is presented with paroxysmal dystonic choreoathetosis transmitted as a dominant trait over five generations. The family is unusual in the marked responsiveness of the episodes to short periods of sleep in several members, in the very variable age of onset, and in the association with prominent myokymia in some cases. These overlap features suggest a link between paroxysmal dystonic choreoathetosis and familial paroxysmal ataxia with myokymia.
一个家族呈现出阵发性肌张力障碍性舞蹈手足徐动症,该疾病作为显性性状在五代人中传递。这个家族不同寻常之处在于,几名成员的发作对短时间睡眠有明显反应,发病年龄差异很大,并且在某些情况下伴有明显的肌纤维颤搐。这些重叠特征提示阵发性肌张力障碍性舞蹈手足徐动症与伴有肌纤维颤搐的家族性阵发性共济失调之间存在联系。
