Abstract
Forty-two patients with senile dementia of the Alzheimer type were compared with normal subjects (51) and with elderly patients with nonorganic psychiatric disorders (40). All were examined by EEG (routine visual inspection and power spectrum density analysis) and VEP (pattern reversal) testing. In dementia the late components (N130, P165, N220) of the VEP are delayed, but the EEG was abnormal more often than the VEP.
摘要
将42例阿尔茨海默型老年痴呆患者与正常受试者（51例）以及患有非器质性精神障碍的老年患者（40例）进行了比较。所有受试者均接受了脑电图检查（常规肉眼检查和功率谱密度分析）和视觉诱发电位（模式翻转）测试。在痴呆患者中，视觉诱发电位的晚期成分（N130、P165、N220）出现延迟，但脑电图异常的情况比视觉诱发电位更常见。
