Head drop is characterized by marked anterior flexion of the cervical spine. As a result, the affected patient presents with the head tilted forward and the chin resting on the chest. We report a 75-year-old male patient with parkinsonism and head drop caused by isolated myasthenic weakness of the neck extensor muscles. Our case is the second report of isolated head drop as a presenting symptom of myasthenia gravis in a patient with parkinsonism.
低头症的特征是颈椎明显向前屈曲。因此，受影响的患者头部向前倾斜，下巴抵在胸部。我们报告了一名75岁的男性帕金森病患者，其低头症是由颈部伸肌孤立性肌无力引起的。我们的病例是第二例将孤立性低头症作为帕金森病患者重症肌无力首发症状的报告。
