A group of 237 elderly patients with dementia of Alzheimer type (DAT) or multi-infarct dementia (MID) was randomly selected in a large geriatric institution in Milan. Mean age of the sample was 78.9 years, 160 (67.5%) were DAT patients and 77 (32.5%) were MID patients. Half of the sample had low levels of autonomy and after 4 years 183 (77.2%) patients were dead. Predictors of mortality, according to a univariate analysis, were age, level of autonomy and type of diagnosis (DAT vs. MID). Mortality rate after 4 years was significantly higher (p less than 0.001) in DAT (86.9%) than in MID (57.1%) patients.
在米兰的一家大型老年病机构中，随机挑选了一组237名患有阿尔茨海默型痴呆（DAT）或多发梗死性痴呆（MID）的老年患者。样本的平均年龄为78.9岁，其中160名（67.5%）为DAT患者，77名（32.5%）为MID患者。一半的样本自主性水平较低，4年后183名（77.2%）患者死亡。单因素分析显示，死亡率的预测因素为年龄、自主性水平和诊断类型（DAT与MID）。4年后，DAT患者的死亡率（86.9%）显著高于MID患者（57.1%）（p<0.001）。
