title: CAMCOG as a screening instrument for dementia: the Odense study. Cambridge Cognitive Examination.
abstract: OBJECTIVE
  The Cambridge Cognitive Examination (CAMCOG) score is correlated with age and sociodemographic variables. The aim of the study was to determine an individualized CAMCOG cut-off score for dementia, taking such correlates into account.
  
  
  METHODS
  From the general population 150 people aged 65-84 years were examined with CAMDEX which includes CAMCOG, and a neuropsychological test battery. Data from 130 non-demented people were entered in setwise multiple regression analyses to identify variables predicting the CAMCOG score.
  
  
  RESULTS
  The variables age, social class, matrimonial status, general knowledge and intellectual level explained 66% of the variance of the CAMCOG scores. A cut-off defined as a difference between actual and predicted CAMCOG score < or = -4.41 resulted in a sensitivity of 88.2% and a specificity of 89.2% for very mild to moderate dementia.
  
  
  CONCLUSIONS
  It is possible to determine an individualized CAMCOG cut-off score for dementia in its early stages.
