Palatal tremor is a rare movement disorder characterized by rhythmic contractions of the soft palate. It is most often symptomatic, secondary to brainstem or cerebellar disease and, in rarer cases, is categorized as essential in the absence of documented brain lesions. There have also been reports in the literature of cases of palatal tremor described as psychogenic because they were associated with psychological or psychiatric disorders. We describe the case of a 12-year-old boy with palatal tremor presenting clinical features of symptomatic essential and psychogenic palatal tremor, thus suggesting a neuropsychopathological continuum between the different forms of disease.
腭肌震颤是一种罕见的运动障碍，表现为软腭的有节律性收缩。它通常是有症状的，继发于脑干或小脑疾病，在极少数情况下，在没有记录到脑部病变的情况下被归类为原发性。文献中也有报道称，一些腭肌震颤病例被描述为心因性的，因为它们与心理或精神障碍有关。我们描述了一例 12 岁男孩出现腭肌震颤，表现出症状性原发性和心因性腭肌震颤的临床特征，因此提示不同疾病形式之间存在神经精神病理学的连续性。
