Abstract：Objective To analyze the clinical factors associated with CT image in diagnosis of elderly brain atrophy patients with mental disorder.Methods Forty elderly brain atrophy patients with mental disorder served as group A,40 elderly brain atrophy patients without mental disorder served as group B,and 40 healthy people served as group C in this study.The chacteristics of their CT image were retrospectively analyzed.Their CT imaging indicators (including the width of ventricle,brain pool,brain ditch and the CT value of white matter) were recorded and analyzed.Results The width of ventricle,brain pool,brain ditch and the CT value of white matter were significantly different in 3 groups (P＜0.01).The width of ventricle,brain pool,brain ditch was significantly longer while the CT value of white matter was significantly lower in groups A and B than in group C (17.2±4.9 mm and 15.7±3.9 mm vs 12.2±3.0 mm,8.7±2.8 mm and 6.9±2.5 mm vs 3.9±1.0 mm,24.3±5.1 mm and 20.8±4.5 mm vs 14.3±3.2 mm,28.2±4.3 HU and 33.9±5.0 HU vs 38.1±6.3 HU,P=0.000).The width of brain ditch was significantly longer while the CT value of white matter was significantly lower in group A than in group B (P＜0.05).The incidence of ischemic stroke and white matter demyelination was significantly higher in group A than in group B (40.0％ vs 17.5％,P =0.26;47.5％ vs 25.0％,P=0.36).Conclusion Brain atrophy patients with mental disorder demonstrate worse CT findings and those with white matter demyelination and ischemic stroke are more prone to occur mental disorder.
