A randomly selected sample of subjects aged 65 years and over was investigated to determine the prevalence of dementia. The sample, which was stratified by age, consisted of 559 subjects living in the community and institutions. It was estimated that 7.7% of those aged 65 years and over suffered from dementia. The disorder affected both sexes equally. There was a marked increase in the prevalence with age so that in those 80 years and over the prevalence rate of dementia was found to be 19%. Those suffering from dementia were significantly more likely to be receiving institutional care than those with normal intellectual function. Those with dementia used significantly more domiciliary services than did those with normal mental function and were more likely to require additional services not already provided. There was a particular need for district nursing supervision, day care and relief admissions. The high prevalence rate of dementia in the elderly, and the high use those suffering from the disorder make of both domiciliary and institutional services, should be appreciated in the planning of services for the elderly.
对随机抽取的65岁及以上的受试者样本进行了调查，以确定痴呆症的患病率。该样本按年龄分层，由559名居住在社区和机构中的受试者组成。据估计，65岁及以上的人群中有7.7%患有痴呆症。这种疾病对男女的影响相同。患病率随年龄显著增加，因此在80岁及以上的人群中，痴呆症的患病率为19%。与智力功能正常的人相比，患有痴呆症的人接受机构护理的可能性要大得多。患有痴呆症的人使用的家庭护理服务明显多于智力功能正常的人，并且更有可能需要尚未提供的额外服务。特别需要地区护理监督、日托和临时住院服务。在规划老年人服务时，应认识到老年人中痴呆症的高患病率，以及患有这种疾病的人对家庭和机构服务的高使用率。
