本文对１６０例头颅ＣＴ检查示白质低密度的患者进行改良长谷川痴呆量表（ＨＤＳ）和简明精神状态检查（ＭＭＳＥ）．结果表明１６０例中仅有５８例有智能障碍，因此，仅以ＣＴ改变诊断Ｂｉｎｓｗａｎｇｅｒ’病是不合适的，必须结合临床智能检查。５８例中有高血压病史者４６例，局灶性神经系统症状和体征４５例，语言减少５２例，动作减少４７例，尿便控制障碍１４例。头颅ＣＴ扫描示多发性白质疏松３３例，侧脑室体疏松９例，半卵圆中心７例，前角６例，后角３例。７例重度痴呆的患者有６例为多发性白质疏松。痴呆与白质疏松的部位和范围密切相关。
In this study, 160 Hatagawa Dementia Scale (HDS) and Conclusive Mental State Examination (MMSE) were performed on 160 patients with white matter low density skull CT examination. The results showed that only 58 out of 160 patients had mental retardation. Therefore, it is not appropriate to diagnose Binswanger’s disease by CT alone. Clinical intelligence tests must be combined. Among the 58 cases, there were 46 cases with history of hypertension, 45 cases with focal neurological symptoms and signs, 52 cases with reduced speech, 47 cases with reduced motion and 14 cases with dysuria. Head CT scan showed multiple leukoaraiosis in 33 cases, 9 cases of lateral ventricular relaxation, the center of the semi-oval in 7 cases, 6 cases of anterior horn, posterior horn in 3 cases. Six of seven patients with severe dementia had multiple white matter lesions. Dementia is closely related to the site and range of leukoaraiosis.
