Abstract

Abstract: Frailty has been recognized as a risk factor for geriatric adverse events.However，current definition and screening of frailty only reflect the physical and physiological factors，and the concepts and studies related to frailty in cognition and social psychology still need to be supplemented.Introduced in this paper，the International Academy on Nutrition and Aging（I.A.N.A）and the International Association of Gerontology and Geriatrics（I.A.G.G）in 2013 provided the first definition of a “Cognitive Frailty” condition in older adults.The key factors defining include presence of physical frailty and cognitive impairment and exclusion of concurrent dementia or other dementias.Besides the propose and improvement of the concept of cognitive frailty，this paper expounds its possible mechanism and risk factors.In addition，some epidemiological studies involving cognitive frailty are summarized.The paper shows that the presentation of cognitive frailty is an important part of the research process of frailty，and individuals and society should pay enough attention to this new concept，which can make contributions to the formulation of strategies to prevent cognitive frailty in the elderly.Furthermore，in line with the assumptions of the bio-psycho-social model，frailty，as a comprehensive concept，should also include psychological，and social components.So social psychological factors should be taken as the future research direction.

摘要： 衰弱已被公认为老年不良事件的危险因素之一。然而目前对于衰弱的定义与筛查多只体现了身体生理因素方面，与衰弱相关的认知及社会心理方面的概念与研究仍需完善。本文介绍了由国际营养与衰老研究所和国际老年医学和老年医学协会于2013年首次提出的认知衰弱的概念，即同时存在身体衰弱和认知损害，并排除老年痴呆或其他类型痴呆，叙述了认知衰弱概念的提出及完善，并简述了认知衰弱可能的机制及可能造成认知衰弱的危险因素，还归纳了涉及认知衰弱的一些流行病学研究。分析表明，认知衰弱的提出是衰弱研究进程中重要的一部分，个人和社会应对这一新兴概念予以足够的重视，最终为制定预防老年人认知衰弱的策略做出贡献。此外，根据生物-心理-社会模型的假设，衰弱作为一种综合概念，还应该包括社会心理方面，未来应将与衰弱相关的社会心理因素作为下一步的研究方向。
