title: [Influence of educational status on a screening test for dementia, the Mini-Mental State Examination].
abstract: This study aimed to examine the relationships between the educational level and the Mini-Mental State Examination (MMSE) total scores and its different items. In a survey dealing with cerebral aging, the MMSE administered 2,792 subjects aged 65 years and over, who continued to live at home. The total score decreased with age and increased markedly when the educational level rose. The proportion of failures was higher than or equal to 10% for 12 of the 30 MMSE items, including the 5 items designed to measure attention ability (serial subtractions) and the 3 ones exploring delayed memory. Regarding these 12 items, the percentage of failures increased homogeneously with age, but the relationship with educational level was heterogeneous: it was very strong for the calculation items, weaker for the delayed memory items. These results pointed to the complex relationships between MMSE scores and educational level, and suggested a possible bias related to the screening tool in dementia surveys.
