摘要

研究人员记录了20名多梗死性痴呆患者、20名脑梗死性疾病非痴呆患者和20名年龄匹配的对照组的视觉诱发电位，包括P300反应和反应时间。此外，使用wais指数对患者进行评估。两组患者P300潜伏期和反应时间均延长，与wais指数显著相关。然而，关于P300潜伏期和反应时间的影响不够强，无法进行单独分类。

[P300 and dementia: diagnostic relevance. I].

Visual evoked potentials, including the P300 response, and reaction time were recorded from 20 patients with multi-infarct dementia, 20 nondemented patients with brain-infarct diseases, and 20 age-matched control subjects. Additionally the patients were assessed using the WAIS-index. Prolonged P300 latency and reaction time occurred in both of the patient-groups, correlated significantly with the WAIS-index. However, effects regarding to P300 latency and reaction time were not strong enough to allow individual classifications.
