Paroxysmal Hypnogenic Dyskinesia (PHD) is a rare movement disorder characterized by involuntary movements, including chorea, athetosis, ballismus, and dystonia, which occur during the Non-Rapid Eye Movement (NREM) sleep stage. Therefore, the diagnosis of PHD is highly crucial due to the presence of differential diagnoses such as epilepsy and other sleep disorders. Although numerous mutations have been identified, the etiology of PHD, which arises from dysregulation in basal ganglia functions, remains unclear. We wanted to present a case of a nineteen-year-old girl diagnosed with PHD to draw attention to the diagnosis, etiology, and treatment of PHD.

阵发性催眠性运动障碍 (PHD) 是一种罕见的运动障碍，以不自主运动为特征，包括舞蹈症、手足徐动症、弹跳和肌张力障碍，发生在非快速眼动 (NREM) 睡眠阶段。因此，由于存在癫痫和其他睡眠障碍等鉴别诊断，PHD 的诊断非常重要。尽管已经鉴定出许多突变，但由于基底神经节功能失调引起的 PHD 的病因仍不清楚。我们想介绍一名被诊断患有 PHD 的 19 岁女孩的病例，以引起人们对 PHD 的诊断、病因和治疗的关注。
