应用听觉ｏｄｄｂａｌｌ序列研究了１８例多发性脑梗塞患者的事件相关电位（ＥＲＰｓ）的Ｐ３成分，发现１２例Ｐ３潜伏期比对照组显著延长；长谷川智测量表评分（ＨＤＳ）平均２３．４分，有１３例属轻度智能低下。应用灯盏花素片治疗后， １４例Ｐ３潜伏期显著缩短，ＨＤＳ评分上升。结果提示 ＥＲＰＳ检查有利于早期发现多发性脑梗塞患者认知功能的减退，并可作为一种评价药物疗效的特殊指标。
The auditory oddball sequence was used to study the P3 component of incident-related potentials (ERPs) in 18 patients with multiple cerebral infarction. The latency of P3 in 12 patients was significantly longer than that of the control group. The Hasegawa Chi-Scale (HDS) score was 23.4, Thirteen patients with mild mental retardation. After the application of Breviscapine tablets, 14 cases of P3 latency was significantly shortened, HDS score increased. The results suggest that ERPS examination is conducive to the early detection of cognitive decline in patients with multiple cerebral infarction, and can be used as a special indicator of drug efficacy.
