Cognitive assessment in elderly patients admitted to hospital: the relationship between the shortened version of the Abbreviated Mental Test and the Abbreviated Mental Test and Mini-Mental State Examination

The selection of patients, exclusions, assessments and analyses have been described previously.8 Briefly, all patients aged 60 years and above admitted to the Department of Elderly Medicine during October and November 1997 were included in the study. Patients were assessed with the AMT followed by the MMSE, once the acute phase of the admission was over. The AMT4 score was derived from the AMT score. An AMT4 score of 0–3 indicated impaired cognition and a score of 4 normal cognition.6 The AMT4 score was compared with the AMT and MMSE scores for each patient.
