title: [Validity of complex figure test in differentiation of Alzheimer's disease from non-dementia].
abstract: OBJECTIVE
  To assess the validity of Complex Figure Test(CFT)in differentiating Alzheimer's disease(AD)from non-dementia.
  
  
  METHODS
  Using CFT,we tested 183 AD patients(AD group),1283 cognitively intact individuals(normal control group),and 134 individuals suffered from other diseases that could be easily confused with dementia(confused control group).
  
  
  RESULTS
  The CFT score was 38.7±0.2 in the normal control group,35.3±0.8 in confused control group,23.7±0.8 in mild AD group,and 13.2±1.1 in moderate AD group after adjusted for educational level,age,and sex(all P<0.05).With the 5(th) percentage of the overall score as cutoff point,this tool showed a sensitivity of 73.8% and a specificity of 93.8% in differentiating AD from non-dementia.
  
  
  CONCLUSIONS
  CFT is a sensitive and specific tool in the differentiation of AD from non-dementia.
