A 35-year-old black female with typical torsion dystonia is discussed. Tremors in the right upper extremity began with a febrile illness at age eight. Difficulty in using the extremity began two years later. Overt writhing movements and torticollis began at age 17. The disorder has been progressive, but not disabling. Neurological examination revealed only extrapyramidal motor system dysfunction. Serum dopamine Beta hydroxylase levels were normal, and an evaluation for Wilson's disease was negative. A sibling has minor writing difficulties.
讨论了一名患有典型扭转性肌张力障碍的35岁黑人女性。右上肢震颤始于8岁时的一次发热性疾病。两年后开始出现使用该肢体困难。17岁时出现明显的扭动动作和斜颈。该疾病呈进行性发展，但未导致残疾。神经系统检查仅显示锥体外系运动系统功能障碍。血清多巴胺β羟化酶水平正常，对威尔逊病的评估为阴性。其一名兄弟姐妹有轻微的书写困难。
