METHODS. The prevalence of dementia was investigated in Okinawa Prefecture, Japan. In all, 3524 subjects, > or = 65 years old, were sampled randomly (urban and rural populations 61.1% and 38.9% respectively). Phase 1 of the survey was carried out by specially trained students of the Faculty of Medicine who used the Mini-Mental State (MMS) scale (interview rate: 94.3%) to screen 522 (15.8%) of the 3312 subjects for the phase 2 survey. Phase 2, conducted by psychiatrists using the Diagnostic and Statistical Manual of Mental Disorders (DSM-III-R) criteria, detected 172 cases of dementia. RESULTS. The estimated prevalence of dementia was 6.7%. For women, the rate increased sharply in the 90-99 year old group, and was 41.4%; for men in the 90-99 year old group prevalence was 21.2%. The ratio of Alzheimer-type dementia to multi-infarct dementia was 1.5:1 (men 1.2:1, women 1.7:1). The breakdown of the severity of dementia in the total cases was: mild 16.9%, moderate 30.8%, and severe 52.3%. The number of severe cases increased with age.
方法。在日本冲绳县对痴呆症的患病率进行了调查。总共随机抽取了3524名年龄≥65岁的受试者（城市和农村人口分别占61.1%和38.9%）。调查的第一阶段由医学院经过专门培训的学生进行，他们使用简易精神状态检查表（MMS）（访谈率：94.3%），从3312名受试者中筛选出522名（15.8%）进行第二阶段调查。第二阶段由精神科医生根据《精神疾病诊断与统计手册》（DSM-III-R）标准进行，检测出172例痴呆症病例。结果。痴呆症的估计患病率为6.7%。对于女性，患病率在90至99岁年龄组中急剧上升，为41.4%；对于男性，90至99岁年龄组的患病率为21.2%。阿尔茨海默型痴呆症与多发梗死性痴呆症的比例为1.5:1（男性为1.2:1，女性为1.7:1）。所有病例中痴呆症严重程度的分类为：轻度16.9%，中度30.8%，重度52.3%。重度病例的数量随年龄增长而增加。
