The abbreviated mental test score (AMTS) was introduced by Hodkinson in 1972 rapidly to assess elderly patients for the possibility of dementia. Its uses in medicine have become somewhat wider, e.g. to assess for confusion and other cognitive impairment, although it has mainly been validated in the elderly.
Questionnaire
The following questions are put to the patient. Each question correctly answered scores one point. A score of 7-8 or less suggests cognitive impairment at the time of testing, although further and more formal tests are necessary to confirm a diagnosis of dementia, delirium or other causes of cognitive impairment.
