To study the association between cognitive impairment and early death in elderly patients living in the community.
Case-control study of 410 patients assessed by the mental status questionnaire and followed up after three years.
A general practice in Inverurie, Aberdeenshire, with 14,000 patients.
205 Patients aged greater than or equal to 65 with cognitive impairment according to the mental status questionnaire (score less than or equal to 8) and 205 patients scoring greater than 8 on the questionnaire matched for age and sex.
Death.
The relative risk of death in the cognitively impaired patients overall was 3.5. Those patients who scored less than or equal to 7 on the mental status questionnaire were five times more likely to die than their controls. There was no difference in risk of death between those with severe or moderate cognitive impairment.
Cognitive impairment is associated with early death.
研究社区老年患者认知障碍与过早死亡之间的关联。
采用病例对照研究，对410名患者进行精神状态问卷调查，并随访三年。
阿伯丁郡因弗鲁里的一家全科诊所，该诊所有14000名患者。
根据精神状态问卷，205名年龄大于或等于65岁且有认知障碍的患者（得分小于或等于8分），以及205名在问卷上得分大于8分且年龄和性别匹配的患者。
死亡。
总体而言，认知障碍患者的死亡相对风险为3.5。在精神状态问卷上得分小于或等于7分的患者死亡可能性是对照组的五倍。重度或中度认知障碍患者的死亡风险没有差异。
认知障碍与过早死亡有关。
