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]
