Interpretation

Cutoffs for positive dementia screening:

• • > 20/30 for patient with 6th grade education
  • > 21/30 for patient with 8th grade education
  • > 23/30 for patient with high school education
  • > 24/30 for college graduates
  • test scores do not define dementia because they imply nothing about functional skills
  • demented patients may score in the normal range

ability to recall only 1 of 3 items suggests dementia

only 50% of elderly can correctly perform serial 7s

retired persons frequently error on the date by a day or 2

................................................ Maximum Score

• years of education & heart problems also predict misclassification
• conversion between the Montreal Cognitive Assessment & the Mini-Mental Status Examination
