title: [Clock drawing task as screening for cognitive impairment in the elderly population].
abstract: This study compared the "Clock-Drawing Task" to the Mini-Mental State Test (MMST) in 834 elderly persons. A cut-off score of 20 or less on the MMST was used to determine cognitive impairment. The "Clock drawing Task" was score of 20 or less on the MMST was used to determine cognitive impairment. The "Clock drawing Task" was scored by three components; frame, numbers, and two hands. Using a criterion of completion on two or more of the three components, the sensitivity, specificity, and correct identification of the diagnosis of cognitive impairment of "Clock Drawing Task" were 89%, 65% and 83% respectively. "Clock Drawing" appears to be a practical test which can be useful for clinicians as a screening for cognitive impairment in old age.
