Limits of the 'Mini-Mental State' as a screening test for dementia and delirium among hospital patients.
With a psychiatrist's standardized clinical diagnosis as the criterion, the 'Mini-Mental State' Examination (MMSE) was 87% sensitive and 82% specific in detecting dementia and delirium among hospital patients on a general medical ward. The false positive ratio was 39% and the false negative ratio was 5%. ⋯ Performance on specific MMSE items was related to education or age. These findings confirm the MMSE's value as a screen instrument for dementia and delirium when later, more intensive diagnostic enquiry is possible; they reinforce earlier suggestions that the MMSE alone cannot yield a diagnosis for these conditions.
