OBJECTIVE
To analyse the prevalence studies of dementia from 1994 to 2000.
METHODS
The papers were searched on Medline and Lilacs and the inclusion criteria were: to be an original study, that estimated dementia prevalence and investigated community samples.
RESULTS
thirty-eight studies were evaluated from all continents. The mean age-specific prevalence rates of dementia were 1,17% for the 65-69 years group, and 54,83% over 95 years. The results were strongly influenced by age. Dementia prevalence rates were higher on women on 75% of the papers reviewed. The Alzheimer's disease/vascular dementia ratio was higher in South America and lower in Asia.
DISCUSSION
Methodological advances were found, specially regarding the homogeneity of diagnostic criteria. The effect of age on the rates of dementia prevalence was pronounced, up to 90 years of age.
目的
分析1994年至2000年痴呆症的患病率研究。
方法
在Medline和Lilacs上检索相关论文，纳入标准为：原创研究，估计痴呆症患病率并调查社区样本。
结果
对来自各大洲的38项研究进行了评估。65 - 69岁年龄组痴呆症的年龄特异性患病率平均为1.17%，95岁以上为54.83%。结果受年龄影响很大。在所审查的75%的论文中，女性的痴呆症患病率更高。南美洲的阿尔茨海默病/血管性痴呆比率更高，亚洲则更低。
讨论
发现了方法学上的进展，特别是在诊断标准的同质性方面。年龄对痴呆症患病率的影响在90岁之前很明显。
