title: [The 'clock drawing test' in healthy elderly people].
abstract: OBJECTIVE
  In this paper we aim to determine the normal values of the clock drawing test in a sample group of 58 healthy elderly persons as a neuropsychological parameter for the evaluation of certain cognitive functions.
  
  
  METHODS
  For this we have used our own adaptation of the quantitative parameters of the clock drawing test in the evaluation 'on command' and 'on copying'. We have also evaluated the possible interaction of the test with the following sample parameters: sex, age, and educational level and we have calculated the inter-examiner reliability of the test.
  
  
  RESULTS
  The average scores obtained were: 8.04 'on-command' (SD 1.60) and 9.20 (SD 0.93) 'on-copying'.
  
  
  CONCLUSIONS
  On analysis of our results we have not observed interaction of the parameters used (age, sex and educational level) with the scores obtained in the test, while there was a high level of inter-examiner reliability.
