This paper was to develop a short bedside cognitive behavioral test for screening dementia in Thai population. The 182 elderly subjects were gathered from a community near the vicinity of Siriraj Hospital. Family interview, CDT ADL assessment were assessed by trained nurse. Neurology residents conducted TMSE and Physical examination. The diagnosis of dementia was using the DSM IV criteria. 67 subjects were diagnosed with dementia by DSM IV criteria. 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. The combination of CDT and ADL questionnaire help increase sensitivity and specificity for screening dementia.
