【摘要】：目的比较阿尔茨海默病(AD)与血管性痴呆(VD)头颅磁共振成像(MRI)和脑电图特征。方法观察39例AD患者、56例VD患者的头颅MRI和脑电图资料。MRI比较大脑萎缩、海马萎缩、脑白质疏松症的比例;脑电图比较轻度异常和中重度异常的比例,进行功率谱分析。结果与VD患者相比,AD患者大脑萎缩、海马萎缩的发生率较高,脑白质疏松症发生率较低。AD患者脑电图中重度异常的较多,(θ+δ)/(α+β)比值增高(P0.05)。结论单纯大脑萎缩而缺乏脑白质疏松症和缺血灶的痴呆患者应高度怀疑AD,脑电图出现中重度异常则进一步支持AD的诊断。
[Abstract]:Objective to compare the characteristics of brain magnetic resonance imaging (MRI) and electroencephalogram (EEG) between Alzheimer's disease (AD) and vascular dementia (VDV). Methods the brain MRI and EEG data of 56 VD patients with AD were compared with those of brain atrophy and hippocampal atrophy. The proportion of leukoaraiosis and the proportion of mild and severe abnormal EEG were analyzed by power spectrum analysis. Results compared with VD patients, the incidence of cerebral atrophy and hippocampal atrophy was higher in AD patients. The incidence of leukoaraiosis is lower. The incidence of AD patients with severe abnormal EEG is higher than that of AD patients (P 0.05). Conclusion the dementia patients with simple brain atrophy and lack of leukoaraiosis and ischemic focus should be highly suspicious of ADand EEG. Moderate and severe abnormalities further support the diagnosis of AD.
