Dementia (also known as major neurocognitive disorder) is defined by a significant decline in 1 or more cognitive domains that interferes with a person's independence in daily activities. Dementia affects an estimated 2.4 to 5.5 million individuals in the United States, and its prevalence increases with age.
To update its 2014 recommendation, the US Preventive Services Task Force (USPSTF) commissioned a review of the evidence on screening for cognitive impairment, including mild cognitive impairment and mild to moderate dementia, in community-dwelling adults, including those 65 years or older residing in independent living facilities.
This recommendation applies to community-dwelling older adults 65 years or older, without recognized signs or symptoms of cognitive impairment.
The USPSTF concludes that the evidence is lacking, and the balance of benefits and harms of screening for cognitive impairment cannot be determined.
The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for cognitive impairment in older adults. (I statement).
痴呆症(也称为重大神经认知障碍)的定义是 1 个或多个认知领域的显著下降,导致患者在日常生活活动中无法独立。据估计,美国有 240 万至 550 万人患有痴呆症,其患病率随着年龄的增长而增加。
为了更新其 2014 年的建议,美国预防服务工作组(USPSTF)委托对社区居住的成年人(包括 65 岁或以上居住在独立生活设施中的成年人)进行认知障碍筛查(包括轻度认知障碍和轻度至中度痴呆)的证据进行审查。
本建议适用于社区居住的 65 岁或以上的老年人,没有认知障碍的明显迹象或症状。
USPSTF 得出结论,证据不足,无法确定筛查认知障碍的利弊平衡。
USPSTF 得出结论,目前的证据不足以评估对老年人进行认知障碍筛查的利弊平衡。(I 级声明)。
