assessing the MTS

Last reviewed 01/2018

The patient scores one point for each correct answer in the mental test score as long as the criteria are fulfilled, e.g. the time is given correct to the nearest hour.

A score of 8 to 10 is normal - note that it is very easy for a patient not to know the time.

A score of 7 is probably abnormal, and any less is definitely abnormal.

The score is invalid if the patient:

  • is delirious
  • has an affective disorder
