Interpretation of Mini-Mental State Examination scores in community-dwelling elderly and geriatric neuropsychiatry patients.

The purpose of this article is to provide data for advanced interpretation of MMSE performance in community-dwelling elderly persons and in geriatric neuropsychiatry inpatients. Age- and education-corrected cutoff scores, standard errors of measurement and standard errors of difference were computed using previously published population normative data (Crum et al., 1993). The supplementary normative table provides a means of interpreting MMSE performance at a single point in time, or at two testing intervals. These same scores were calculated for a sample of 248 elderly inpatients from the geriatric psychiatry division of a psychiatric hospital. Clinical examples are provided.
