The aim of the two-phase population based study was to estimate the prevalence of dementia. Among the population aged 65-84 years of the Warsaw district Mokotów, the stratified sample consisted of 1,000 persons taken randomly. The first-screening phase (MMSE) was conducted by raters among 893 persons. 92 subjects with disturbances of cognitive functions were qualified to the second-diagnostic phase and 89 were given a diagnostic examination with the Cambridge Mental Disorders of the Elderly Examination. The following age-specific prevalences of dementia were found in the age-groups 65-69, 70-74, 75-79, 80-84: 1.9, 5.8, 8.6 and 16.5% respectively. Rates for vascular dementia (2.7) were higher than those for dementia of the Alzheimer's type (2.3), mixed dementia (0.5), and secondary dementia (0.2%). In the younger subgroups (65-74 y), vascular dementia was the most frequent and in the older subgroups (75-84 y) the most frequent was Alzheimer's type. The rates of dementia were quite similar to those found in other European studies.
这项基于人群的两阶段研究旨在估计痴呆症的患病率。在华沙莫科托夫区65 - 84岁的人群中，分层样本由随机抽取的1000人组成。第一筛查阶段（简易精神状态检查表）由评估人员对893人进行。92名认知功能障碍受试者进入第二诊断阶段，其中89人接受了老年精神障碍剑桥检查表的诊断检查。在65 - 69岁、70 - 74岁、75 - 79岁、80 - 84岁年龄组中发现的痴呆症年龄特异性患病率分别为1.9%、5.8%、8.6%和16.5%。血管性痴呆的患病率（2.7%）高于阿尔茨海默病型痴呆（2.3%）、混合型痴呆（0.5%）和继发性痴呆（0.2%）。在较年轻的亚组（65 - 74岁）中，血管性痴呆最为常见，而在较年长的亚组（75 - 84岁）中，最常见的是阿尔茨海默病型。痴呆症的患病率与其他欧洲研究的结果相当相似。
