However, these cognitive tests and informant reports are not always available. The present study investigated three screening methods using the Mini\u2010Mental State Examination (MMSE<\/jats:styled-content>) as the cognitive test, and the K<\/jats:styled-content>orean dementia screening questionnaire (KDSQ<\/jats:styled-content>) as the informant report.<\/jats:p><\/jats:sec>Methods<\/jats:title>Participants were recruited from the K<\/jats:styled-content>orea Clinical Research Center for Dementia of S<\/jats:styled-content>outh K<\/jats:styled-content>orea, and included 2861 patients with Alzheimer's disease (dementia), 3519 patients with mild cognitive impairment and 1375 controls with no cognitive dysfunction. Three screening methods were tested: (i) MMSE<\/jats:styled-content> alone (MMSE<\/jats:styled-content>cut\u2010off<\/jats:sup>); (ii) a conventional combination of MMSE<\/jats:styled-content> and KDSQ<\/jats:styled-content> (MMSE<\/jats:styled-content>+KDSQ<\/jats:styled-content>cut\u2010off<\/jats:sup>); and (iii) a decision tree with MMSE<\/jats:styled-content> and KDSQ<\/jats:styled-content> (MMSE<\/jats:styled-content>+KDSQ<\/jats:styled-content>decision tree<\/jats:sup>).<\/jats:p><\/jats:sec>Results<\/jats:title>For discriminating any cognitive dysfunction from controls, MMSE<\/jats:styled-content>+KDSQ<\/jats:styled-content>cut\u2010off<\/jats:sup> had the highest area under the receiver operating characteristic curve (0.784). For discriminating dementia from controls, MMSE<\/jats:styled-content>+KDSQ<\/jats:styled-content>cut\u2010off<\/jats:sup> had the highest area under the receiver operating characteristic curve (0.899). For discriminating mild cognitive impairment from controls, MMSE<\/jats:styled-content>cut\u2010off<\/jats:sup> had the highest area under the receiver operating characteristic curve (0.683). MMSE<\/jats:styled-content>+KDSQ<\/jats:styled-content>decision tree<\/jats:sup> showed the highest sensitivity for all discriminations. For overall classification accuracy, MMSE<\/jats:styled-content>+KDSQ<\/jats:styled-content>decision tree<\/jats:sup> had the highest value (70.0%).<\/jats:p><\/jats:sec>Conclusions<\/jats:title>These three methods had different advantageous properties for screening and staging cognitive dysfunction. As there might be different availability across clinical settings, these three methods can be selected and used according to situational needs.
