Cognitive rating scales: A comparison of the mini‐mental state examination and the middlesex elderly assessment of mental state

The MEAMS (Middlesex Elderly Assessment of Mental State) is a relatively new scale specifically developed to detect intellectual impairment secondary to organic brain dysfunction in the elderly. In this study the MEAMS was compared with the MMSE (Mini‐Mental State Examination), a widely known and commonly used brief cognitive rating scale, in a group of 60 elderly acute psychiatric inpatients. Scores on both scales were highly correlated. However, the MEAMS was shown to be more sensitive in the detection of mild cognitive impairment, and was more sensitive to the presence of focal brain lesions than the MMSE. In the second part of the study, a further 25 inpatients were assessed using both scales by six junior and staff‐grade doctors, who then rated the scales according to various criteria. Despite taking slightly longer to administer, the MEAMS was rated superior overall by the medical staff. It is suggested that the MEAMS is a sensitive instrument acceptable to both patients and staff, and is suitable for routine use in an old age psychiatric setting.
