作者前瞻性研究193例住院痴呆病人,以评价 CT 对 Alzheimer 病(AD)及血管性痴呆(vascular de-mentia,VD)的鉴别诊断作用。193例中完全符合 AD临床标准者68例,完全符合 VD 临床标准者125例。根据临床和 CT 资料,又进一步将 VD 分为多发性梗塞性痴呆(multi-infarct dementia,MID)79例和可能的血管性痴呆(probable vascular dementia,PVD)46例。CT 扫描由两位不了解病人诊断的医生进行。主要根据 CT 所见的脑梗塞部位、脑室周围白质低密度(white matter low attenuation,WMLA)改变和
The prospective study of 193 patients with dementia in hospital to evaluate the differential diagnosis of Alzheimer’s disease (AD) and vascular dementia (VD). Among the 193 cases, 68 patients were completely conformed to AD clinical criteria and 125 patients were in full compliance with VD clinical criteria. VD was further divided into 79 cases of multi-infarct dementia (MID) and 46 cases of probable vascular dementia (PVD) according to clinical and CT data. The CT scan was performed by two doctors who did not know the patient’s diagnosis. Mainly based on CT findings of cerebral infarction, periventricular white matter low attenuation (white matter low attenuation, WMLA) changes and
