本征系指发作性周期性睡眠过多并有严重的饥饿感、运动不安、易激惹和轻度意识障碍的病征而言的。本征的病因目前尚不清楚,可能与颅内器质性病变(脑瘤、颅脑损伤、脑炎)、某些内分泌或代谢性疾病有密切关系。目前,认为某种原因导致丘脑下部的司管意识,睡眠、觉醒的中枢发生缺陷,是诱发本征的病理基础。 Indications mean episodes of episodic periodic sleepiness with severe hunger, motor disturbances, irritability and mild disturbance of consciousness. The etiology of the etiology is unclear, and may be closely related to intracranial organic diseases (brain tumor, brain injury, encephalitis) and some endocrine or metabolic diseases. At present, it is considered that a certain reason causes a defect in the central part of the hypothalamus, which is the consciousness of the supervisor, the sleep and the awakening, and is the etiological basis for etiology.
