General practice patients aged 75 years and over were screened for cognitive impairment using the Mini-Mental State Examination. Those scoring 23 or below and a sample of those scoring 24 or 25 were assessed using the Cambridge Mental Disorders of the Elderly Examination (CAMDEX), a structured interview schedule specifically designed to detect mild dementia. The CAMDEX includes a mental state examination, a psychiatric history, detailed cognitive testing and an information interview. The prevalence of dementia in 2311 patients was found to be 10.5%, about half that found in most earlier studies. Possible reasons for this low rate are discussed.
使用简易精神状态检查表对75岁及以上的全科医疗患者进行认知障碍筛查。得分23分及以下的患者以及得分24分或25分的部分患者样本，使用老年人剑桥精神疾病检查表（CAMDEX）进行评估，这是一种专门设计用于检测轻度痴呆的结构化访谈表。CAMDEX包括精神状态检查、精神病史、详细的认知测试和信息访谈。在2311名患者中，痴呆症的患病率为10.5%，约为大多数早期研究中发现患病率的一半。文中讨论了这一低患病率的可能原因。
