We studied the prevalence of different types of dementia in an elderly population in Stockholm, Sweden, in relation to age, sex, and education. The study confirmed Alzheimer's disease (AD) as the most frequent type of dementia and the positive association of dementias with age, even in the most advanced ages. In contrast to previously reported data, we found the same proportion of AD and vascular dementia in the different age strata, and no sex differences regarding the prevalence of different dementia types. Finally, less educated people had a higher prevalence of all dementias, due essentially to a higher prevalence of alcoholic dementia and unspecified type of dementia. The prevalence of AD was similar across different levels of education.
我们研究了瑞典斯德哥尔摩老年人群中不同类型痴呆症的患病率与年龄、性别和教育程度之间的关系。该研究证实，阿尔茨海默病（AD）是最常见的痴呆症类型，并且痴呆症与年龄呈正相关，即使在高龄阶段也是如此。与先前报道的数据不同，我们发现在不同年龄层中，AD和血管性痴呆的比例相同，并且不同类型痴呆症的患病率不存在性别差异。最后，受教育程度较低的人群中所有痴呆症的患病率较高，这主要是由于酒精性痴呆和未明确类型痴呆症的患病率较高。不同教育水平下AD的患病率相似。
