With the deepening and acceleration of the aging process, an increasing prevalence of mild cognitive impairment (MCI) is found in China's elderly population. To reduce MCI prevalence in this group, early screening and diagnosis are approaches having great social significance. To provide support for the choice of appropriate tools for early screening and identifying MCI in community-dwelling Chinese older adults, we comprehensively reviewed the commonly used scales in clinical MCI screening and assessment〔Informant Questionnaire on Cognitive Decline in the Elderly Individuals (IQCODE) , Cambridge Neuropsychological Test Automated Battery, Montreal Cognitive Assessment, Clock Drawing Test, Clock Reading Test, Clock Setting Test, Consortium to Establish a Registry for Alzheimer's Disease, Ascertain Dementia 8 (AD8) , Addenbrooke's Cognitive Examination-Revised (ACE) , and General Practitioner Assessment of Cognition〕, and put forward a strategy after analyzing the advantages and disadvantages of each of the above-mentioned scales, namely, combined use of the quick and highly effective AD8, IQCODE, and the sensitive and comprehensive ACE, for these three scales may make up for each other's shortcomings when they are used together.
