The right strategy to adopt across different healthcare settings remains unclear. This diagnostic study compared the performance of the three strategies for detecting dementia (primary aim), as well as for detecting both mild cognitive impairment (MCI) and dementia (secondary aim).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Participants aged \u226565\u00a0years (<jats:italic>n<\/jats:italic>\u00a0=\u00a011\u00a0057) were recruited from Alzheimer\u2019s Disease Centers across the USA. Participants provided data on an informant report (Functional Activities Questionnaire), brief cognitive test (four\u2010item short variant of Montreal Cognitive Assessment) and a combined measure with informant report and brief cognitive test (sum of Functional Activities Questionnaire and Montreal Cognitive Assessment short variant). They also received standardized assessments (clinical history, physical examination and neuropsychological testing) to diagnose MCI and dementia. Areas under the receiver operating characteristic curve (AUCs) of the three strategies were compared using the DeLong method, with AUC\u00a0&gt;\u00a090% indicating excellent performance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>All three strategies had excellent performance in detecting dementia, although informant report [AUC, 95.9%; 95% confidence intervals (CI), 95.4\u201396.3%] was significantly better than brief cognitive test (AUC, 93.0%; 95% CI, 92.4\u201393.6%) and the combined measure had the best performance (AUC, 97.0%; 95% CI, 96.7\u201397.4%). However, to detect both MCI and dementia, only the combined measure had excellent performance (AUC, 93.0%; 95% CI, 92.5\u201393.4%), whereas stand\u2010alone informant report or brief cognitive test performed suboptimally (AUC\u00a0&lt;\u00a090%).
