基于单次提取的长潜伏期诱发电位的研究

The study of long-latency evoked potential based on the single trial

目的探讨单次提取长潜伏期诱发电位在评价人类认知功能障碍方面的作用。方法选取具有认知功能障碍的异常组与正常组受试者的长潜伏期诱发电位,对其各个主要波的波形、潜伏期与波幅进行评价、对比。结果正常组与异常组的长潜伏期诱发电位在波形、潜伏期和波幅均有明显差异(P<0.05)。结论单次提取长潜伏期诱发电位可以一定程度上反映出人类在认知功能方面的改变所引起的变化,对临床上辅助诊断精神方面的疾病以及智能的退化、障碍具有一定的价值。

Objective To know the effect of the single trial long-latency evoked potential on the cognitive impairment.Methods The long-latency evoked potentials from the cognitive impairment abnormal cases and normal group were collected,the differences among the waveform,latency and the amplitude of each main wave were contrasted and analyzed.Results There are significant differences among the waveform,the latency and the amplitude of the long-latency evoked potentials between the normal group and the abnormal group（P0.05）.Conclusion To some extent,the single trial of long-latency evoked potentials can reflect the changes caused by the changes of cognitive impairment.It has certain value in diagnosing psychic diseases and degeneration in intelligence in clinic.
