pearls
usecase
Elderly patients, both outpatient and inpatient.
reasons
Easy to use and yields a simple dichotomous outcome. The full AMT has been shown to be infrequently and incorrectly used in practice. The AMT-4 has been shown to have statistically significant close correlation with the full AMT score throughout its range of values.
next_advice
Evaluate for reversible causes of altered mental status in patients deemed to have abnormal cognition.
