Abbreviated mental test score
The Abbreviated Mental Test score (AMTS) is a 10-point test for rapidly assessing elderly patients for the possibility of dementia. It was first used in 1972,[1][2] and is now sometimes also used to assess for mental confusion (including delirium) and other cognitive impairments.

A 4-item version called the Abbreviated Mental Test - 4 (AMT4) has been developed and tested.[3]
Abbreviated Mental Test - 4 (AMT4)[edit]
The AMT4 uses 4 items from the AMTS: (i) What is your age? (ii) What is your date of birth? (iii) What is the name of this place? (iv) What is the year? A cut off score of 3/4 performs comparably to an AMTS cut-off score of 8/9.[3] The AMT4 is part of the 4AT scale for delirium.
