In its recent recommendation on screening for cognitive impairment in older adults, the US Preventive Services Task Force (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).”¹ This conclusion, supported by an updated evidence report and systematic review,² is the same one the task force reached in 2014 after similar extensive scrutiny of the evidence base.³ There continues to be insufficient evidence with which to evaluate the benefits and harms of systematic cognitive testing in asymptomatic people 65 years and older. Given the burden of dementia and the intense public interest in preventing cognitive impairment, the lack of progress is disheartening.

美国预防服务工作队（USPSTF）在最近关于筛查老年人认知障碍的建议中得出以下结论：“目前的证据不足以评估筛查老年人认知障碍的利弊之间的平衡（I陈述） 。” ¹该结论得到最新证据报告和系统审查的支持，²与2014年工作队在对证据基础进行了类似的广泛审查之后得出的结论相同。³仍然没有足够的证据来评估65岁及以上的无症状患者进行系统的认知测试的利弊。鉴于痴呆症的负担和预防认知障碍的强烈公众兴趣，缺乏进展令人沮丧。
