摘要
目的:探讨听觉事件相关电位P_(300)在多发梗塞性痴呆的早期诊断中的意义。方法:分别对24名无痴呆的多发性脑梗塞患者及年龄匹配的24名正常人进行神经心理学量表(长谷川智力量表)(HDS)评分及听觉P_(300)检测。结果:两组神经心理学量表(HDS)评分均正常。二组听觉P_(300)比较,无痴呆多发性脑梗塞组P_(300)潜伏期延长,有明显性差异。结论:听觉P_(300)潜伏期可能较HDS评分更为敏感,以及在多发梗塞性痴呆的早期诊断中具有重要意义。
Objective: To explore the significance of P300 in early diagnosis of multiple infarction dementia. Method: Neuropsychological scale (HDS) and P300 of oddball auditory evoked modal were examined in 24 patients with cerebral infarction without dementia and 24 normal subjects with age and sex matched. Results: Two groups were all normal in neuropsychological scale. PL of P300 in patient with cerebral infarction without dementia was prolonged and there was significant difference between two groups. Conclusions: PL of P300 is more sensitive than HDS. PL of P300 might be of great importance in early diagnosis of multiple infarct dementia.
