摘　　要：本文对多梗塞性痴呆(MID)患者的头颅CT图像作双额径(BF)、双尾径(BC)及Ⅲ脑室外侧至半球外侧裂径(ⅢV-S)与其相应颅腔径比率测定。结果表明MID组的BC比率增加,ⅢV-S比率减少,与健康对照组及脑梗塞非痴呆组比较,差异有显著性意义。本文认为多梗塞性痴呆不论梗塞灶的部位和容量大小,其痴呆的产生与Ⅲ脑室外侧壁、丘脑和脑岛之间的结构损害累及丘脑及其投射和Papez环路有关。同时,根据病史、症状和体征结合头颅CT检查有助于鉴别腔隙状态所致的痴呆、Alzheimer氏病的痴呆,以及多发性脑梗塞合并Alzheimer氏病。Measurments of bi-frontal(BF)ratio,bi-caudate (BC) ratio and bi-Ⅲventricleto fissure of Sylvius (ⅢⅤ-S) ratio oncomputed tomography in patients withmultiinfarct dementia (MID) revealed asignificant difference between the studiedand controlled groups. Increased BC ra-tio and decreased ⅢⅤ-S ratio were foundin patients with MID, but not in non-demented patients with cerebral infarc-tion and controlled healthies. There wasno difference between the groups of no-ndemented patients with cerebral infarc-tion and controlled healthies. This sugges-ts that the involvement in the braintissure between thalamus and insula playisn important role in causing dementiain the patients with MID. CorrelationCT scan to adrupt onset, stepwise dete-rioration fluctuating course, history ofstroke and focal neurological symtomsand signs may be responsible for thedifferential diagopsis of dementias.
