What is the AMTS?

The abbreviation mental test score (AMTS) is a 10-point assessment that was introduced by Hodkinson in 1972 in order to quickly evaluate elderly patients for the potential of dementia. It is still used in the screening process for both delirium and dementia, however further tests are necessary for confirmation.

AMTS questions

The following questions are posed to the patient. Each correctly answered question scores one point:

  • What is your age?
  • What is the time to the nearest hour?
  • Give the patient an address and ask them to repeat it (e.g. 42 West Street)
  • What is the year?
  • What is the name of this place? or What is your house number?
  • Can the patient recognize two persons (e.g. doctor, nurse)?
  • What is your date of birth? (day and month sufficient)
  • In what year did World War 1 begin?
  • Name the present monarch/prime minister/president
  • Count backwards from 20 down to 1

AMTS interpretation

A score of 6 or lower suggests delirium or dementia, although further tests are needed for confirmation.
