The clock-drawing test is used for screening forcognitive impairment and dementia and as a measureof spatial dysfunction and neglect. It was originallyused to assess visuo-constructive abilities but we knowthat abnormal clock drawing occurs in other cognitiveimpairments. Doing the test requires verbal under-standing, memory and spatially coded knowledge inaddition to constructive skills [1]. Education, age andmood can influence the test results, with subjects oflow education, advanced age and depression perform-ing more poorly [2 - 4].
