CT studies on 212 normal elderly individuals were analyzed for ventricular enlargement and cortical atrophy. Results show a positive correlation between ventricular enlargement and age with greater degrees of ventricular enlargement and cortical atrophy in men as compared to women. While some degree of atrophy is common in normal elderly individuals it is mild, minimal, or noexistent in 86%.
对212名正常老年人进行了CT研究，分析其脑室扩大和皮质萎缩情况。结果显示，脑室扩大与年龄呈正相关，男性的脑室扩大和皮质萎缩程度高于女性。虽然在正常老年人中一定程度的萎缩很常见，但86%的人萎缩程度较轻、极轻微或不存在。
