The CDT at cut off score of 7 had sensitivity 83.8% and specificity 65.2% with area under ROC being 0.825. For ADL assessment at the cut off score of 5 had sensitivity 74.6% and specificity 79.1% with the area under ROC being 0.849. Using CDT and ADL questionnaires together increased the area under the curve from 0.825 to 0.905. CONCLUSION: The combination of CDT and ADL questionnaire help increase sensitivity and specificity for screening dementia.
