The geriatric community study was conducted by the Aichi Prefecture (Japan) Project. The psychiatric epidemiological survey was conducted using a stratified random sampling method. 3106 community residents over the age of 65 years, randomly selected from the whole Aichi Prefecture of Japan, were interviewed; 476 had suspected dementia. The second interviews and the neurologic examinations were carried out by psychiatrists. The prevalence of dementia was estimated to be 5.8% (moderate and severe, 2.2%; mild 3.6%) of the aged population in the community. Cerebrovascular dementia (CVD) or multi-infarct dementia (MID) was found in 2.8%, senile dementia of the Alzheimer type (SDAT) in 2.4%, and dementia due to other causes in 0.6%. CVD (MID) was diagnosed more frequently in men, and SDAT in women.
老年社区研究由日本爱知县项目开展。精神疾病流行病学调查采用分层随机抽样方法。从日本爱知县全体居民中随机抽取了3106名65岁以上的社区居民进行访谈；其中476人疑似患有痴呆症。第二次访谈和神经学检查由精神科医生进行。据估计，该社区老年人口中痴呆症的患病率为5.8%（中度和重度为2.2%；轻度为3.6%）。发现脑血管性痴呆（CVD）或多发梗死性痴呆（MID）占2.8%，阿尔茨海默型老年痴呆症（SDAT）占2.4%，其他原因导致的痴呆症占0.6%。男性中CVD（MID）的诊断更为常见，女性中SDAT的诊断更为常见。
