| Annotation | Comprehensive neuropsychological test batteries focus on the subtle cognitive deficits in dementia, but a brief screening instrument is also of immense practical value. As the clock-drawing test encompasses a number of cognitive domains frequently disturbed by the dementing process, it is considered to be a suitable screening instrument for the disorder. The authors documented the usefulness of a new scoring method of the clock drawing test for screening of dementia in older Chinese people in Hong Kong. 53 demented and 53 healthy older controls were assessed. At a cut-off score of 3/4, the sensitivity and specificity of the test for screening of dementia was 83% and 79%. With a composite test of clock reading and clock setting, the positive predictive value of the clock face test was 98%. This new scoring method of clock drawing proved to be a valid measure for screening of dementia, and is applicable for use with non-English speaking populations. (RH). |
