检查并统计分析40例无症状老人(正常组)和86例老年眩晕病人(眩晕组)的脑干听觉诱发电位(BAEP)及其结果。得出正常组BAEP各项参数及其上限值,同时以正常组各参数的均值评估眩晕组的BAEP改变。发现后者BAEP异常率为79.1％,发作期检查其异常率升高至87.2％(P<0.05)。本组引起眩晕的病因为脑动脉硬化所致之脑供血不足。少数为脑干梗塞。本文作者认为BAEP改变较CT等特殊检查改变早,建议作为特殊检查前筛选用。
The brainstem auditory evoked potentials (BAEP) in 40 asymptomatic (normal group) and 86 senile vertigo patients (vertigo group) were examined and statistically analyzed. The parameters of BAEP and its upper limit were obtained in the normal group, and the changes of BAEP in the vertigo group were evaluated by means of the mean value of each parameter in the normal group. The abnormal rate of BAEP in the latter group was 79.1%, and the abnormal rate in the attack phase increased to 87.2% (P <0.05). The cause of this group caused by vertigo cerebral cerebral arteriosclerosis due to insufficient blood supply to the brain. A few brainstem infarction. The author of this paper thinks that the change of BAEP should be earlier than the special inspection such as CT, and it is suggested to be used as a special screening test before screening.
