| Annotation | The effectiveness of the Clock Drawing Test (CDT) for dementia detection was compared with that of the Mini-Mental State Examination (MMSE)and the Cognitive Abilities Screening Instrument (CASI) in US community-dwelling elders of diverse linguistic, ethnic, and educational backgrounds. 295 subjects were tested at home in their native languages (English, n=141; another language, n=154). An informant-based clinical dementia history and functional severity index derived from the Consortium to Establish a Registry of Alzheimer's Disease (CERAD) protocols were used to classify subjects as 170 probably demented and 125 probably not. All tests were significantly affected by education, but not by primary language. Sensitivities and specificities for probable dementia were 82% and 92% respectively for the CDT; 92% and 92% for the MMSE; and 93% and 97% for the CASI for those completing each test. However, in poorly educated non-English speakers, the CDT detected demented subjects with higher sensitivity than the other two tests, 85% and 94% respectively for CDT; 46% and 100% for MMSE; and 75% and 95% for CASI. Less information was lost due to non-completion of the CDT than the MMSE or CASI. (RH). |
