摘要
目的 研究Alzheimer 病(AD) 、血管性痴呆(VD) 和健康老年人(NA) 的神经心理学和功能性影像学特征及两者的相关性。方法 对36 例AD、35 例VD 患者和37 名NA 进行神经心理学评定和脑血流灌注显像。结果 AD 和VD 患者各量表成绩显著低于NA,AD 的物品记忆测验成绩(FOM)显著低于VD。AD 和VD患者大部分脑区放射性计数比值(RAR)明显低于NA,AD右顶叶和双额叶的RAR明显低于VD。NA的FOM 与多个脑区的RAR 相关,AD 多项量表成绩与右顶叶RAR相关,VD多项量表成绩与左顶叶RAR相关。结论 左、右顶叶血流灌注下降分别对VD 和AD 的认知缺损有较大影响,提示VD 和AD分别具有不同的左。
