Sixty-six elderly subjects (mean age 77 years) whose mental state was assessed clinically and by simple psychometric tests have been studied by computerised tomography. The mean maximum ventricular area in the 17 mentally normal subjects was above the upper limit of normal for younger subjects, and there was a broad relationship between increasing ventricular dilatation and increasing intellectual impairment. No such clear relationship was demonstrable for measures of cortical atrophy.
通过计算机断层扫描对66名老年受试者(平均年龄77岁)进行了研究,这些受试者的精神状态通过临床评估和简单的心理测量测试进行评定。17名精神正常的受试者的平均最大脑室面积高于年轻受试者的正常上限,脑室扩张增加与智力损害增加之间存在广泛关联。对于皮质萎缩的测量,未发现如此明确的关联。
