Palatal tremor, characterized by rhythmic contractions of the soft palate, can occur secondary to pathology in the dentato-rubro-olivary pathway, or in the absence of such structural lesions. Its pathogenesis is only partially understood. We describe a case of probable drug-induced palatal tremor.
A 27-year-old Indian man had taken carbamazepine and lithium for 7 years for the treatment of a manic episode. He presented with a one-year history of bilateral rhythmic oscillations of his soft palate and tremors of his tongue. There were no other abnormalities detected from his examination or after detailed investigation.
Palatal tremors may result from medication used in the treatment of psychiatric disorders.
腭震颤以软腭有节律的收缩为特征,可继发于齿状红核橄榄束通路的病变,或在无此类结构损伤的情况下发生。其发病机制仅部分为人所知。我们描述了一例可能由药物引起的腭震颤病例。
一名27岁的印度男子因治疗躁狂发作服用卡马西平和锂7年。他出现双侧软腭节律性振荡和舌头震颤1年的病史。检查或详细调查后未发现其他异常。
腭震颤可能由用于治疗精神疾病的药物引起。
