title: [Comparative norms of RAPID neuropsychological battery tests for subjects aged between 50 and 89 years].
abstract: BACKGROUND
  RAPID, a battery of rapid neuropsychological tests, includes neuropsychological tests calibrated for different populations according to diverse methodologies. This makes the comparison and interpretation of the results difficult. The aim of this study was to build comparative norms for the RAPID battery using a single methodology in a unique population.
  
  
  METHODS
  The RAPID Battery includes nine different tests: the Memory Impairment Screen, the Isaacs Set Test, the Mini-Mental State Examination, the Free and Cued Recall Test, the Trail Making Test, a test for copying geometric figures as part of the BEC 96, a test for verbally naming images and a test for matching categories. A cohort of 476 subjects aged 50 to 89 were randomly selected from the medical records of 11 practitioners.
  
  
  RESULTS
  The norms were stratified according to age (50-59, 60-69, 70-79 and 80-89 years) and education level of the subjects. The first level includes subjects with the French Primary Education Certificate or lower. The second level includes subjects with the Certificate of Professional Aptitude or the Brevet (equivalent to the GCSE). The third level includes subjects with the Baccalaureate or higher. Given that most of the tests did not satisfy the normal distribution, percentiles (tenth, twenty-fifth, seventy-fifth, ninetieth percentile and median) were used to define age and education norms. The results show a high participation rate (75 %) and are similar to those obtained in the literature: The results decreased with age and improved in grade level. Nevertheless, the results exhibited great variability for the tenth percentile in comparison with results reported in the literature.
  
  
  CONCLUSIONS
  The development of comparative norms for the RAPID battery from a same sample facilitates the interpretation of individual results in terms of cognitive profile.
