以往曾认为头外伤后眩晕是由于外周损伤引起,而今天则多认为此种眩晕主要是由中枢损伤所致。为了研究头外伤后眩晕的发生机理,作者们观察了62名头外伤6个月以内,主诉有眩晕症状的患者的眼震电图结果。 62名患者中,年龄大都在20～60岁,男性居多。头外伤的原因以交通事故和家庭纠纷为多见。眩晕症状主要是旋转感和向左右倾倒,并伴有植物神经症状,如出汗、恶心、呕吐等。此外,还可合并有单侧或双侧的感觉神经性聋。眼震电图检查之前,详细记录每一患者的病史,仔细进

Vertigo symptoms are mainly rotational sense and dumping to the left and right, and accompanied by autonomic symptoms, such as sweating, nausea, vomiting and so on. In addition, unilateral or bilateral sensory deafness may also be combined. Before the electronystagmography, detailed records of each patient’s medical history, carefully into
