“…Addenbrooke's Cognitive Examination-Revised (ACE-R) is a brief cognitive test revised by Mioshi et al [9] in 2006, and, by contrast, recent series of studies recommended ACE-R as a superior tool for screening for early dementia and a-MCI in normal populations as well as for discriminating different types of dementias [10,11]. At present, ACE-R has been translated into many languages and has been validated in different clinical sites in the UK, Australia, Spain, Greece, Germany, Italy, Portugal, Japan, and Korea [5,12,13,14,15,16,17,18,19,20]. However, the psychometric properties of the Chinese version have not yet been examined.…”
