The purpose of the present study was to examine whether the Stroop color-word test is usefully for detecting cognitive decline. The correlations between the Stroop test and other type attentional test, D-CAT, were also examined. The NU-CAB as cognitive assessment battery was administrated to 1083 healthy community dwellers. The NU-CAB consisted the MMSE, sentences memory test, verbal fluency tests, digit cancellation test (D-CAT), and the Stroop test. We found a significant difference between 70's and over 80's on only RTs of the Stroop test. However we did not find strong correlation with D-CAT. These results suggest that the Stroop test have usefulness for the cognitive decline in old-old age and it reflects other aspect of the attention with D-CAT.
