摘要
目的：探讨事件相关电位（ＥＲＰ）在帕金森病（ＰＤ）痴呆中的诊断价值。方法：对２１例ＰＤ患者进行ＥＲＰ检测及长谷川智能量表（ＨＤＳ）检查。结果：ＰＤ组Ｎ２、Ｐ３潜伏期比对照组显著延长，ＰＤ患者ＥＲＰ阳性率为６２％，ＨＤＳ为３８％。结论：ＥＲＰ检测结果敏感，对帕金森痴呆的诊断。
Objectives:To explore the diagnostic value of event related potential (ERP) in Parkinson′s dementia(PD).Methods:ERP and HDS tests were performed in 21 patients with PD. Results:The peak latencies of N2 and P3 were significantly longer in patients with PD than Those in the normal subjects (P<0.01).The positive rate of ERP and HDS was 62% and 38% respectively.Conclusions: ERP might be more sensitive than HDS,and be of great importance in the diagnosis,especially in early stage.
