【摘要】 对１２例Ａｌｚｈｅｉｍｅｒ型痴呆（ＤＡＴ）、１５例多发梗塞性痴呆（ＭＩＤ）、１５例健康对照组的脑电地形图的定量研究显示：痴呆病人慢波功率的增多不同于正常老化，θ功率是最早增高的指标；ＭＩＤ较ＤＡＴ有更多的不对称性改变；脑电功率不仅与痴呆程度有量化联系，而且和特定认知功能也有量化联系；首次发现ＤＡＴ和ＭＩＤ各有不同的脑电功率和认知功能的量化联系方式。结果表明定量脑电地形图在痴呆研究中有一定应用前景。更多还原

【Abstract】 The quantitative EEG mapping were compared among 15 patients with dementia ofAlzheimer’s type (DAT),15 multi infarct dementia (MID) and 15 age matched normal controls.The results indicated that both the absolute and relative powers of slow waves were significantly higherin dementia groups than in controls, theta power being changed earlier than any others. MID showed more asymmetric distribution than DAT.The authors further found that the brain electric band powercorrelated not only with severity of dementia,but also with specific cognitive function deficit;and thatdifferent type of dementia had different correlating style. These results demonstrated a promising appli-cation of EEG mapping in dementia research.更多还原
