Concurrent validity of Spanish-language versions of the Mini-Mental State Examination, Mental Status Questionnaire, Information-Memory-Concentration test, and Orientation-Memory-Concentration test: Alzheimer's disease patients and nondemented elderly comparison subjects.
One-hundred fifty-eight elderly Spanish-speaking U.S. residents (81 patients diagnosed with Alzheimer's disease and 77 subjects without dementia) were tested with Spanish-language versions of four brief cognitive assessment instruments: the Mini-Mental State Examination (S-MMSE), the Mental Status Questionnaire (S-MSQ), the Information-Memory-Concentration test (S-IMC), and the Orientation-Memory-Concentration test (S-OMC). Within-group performances were highly correlated for all four instruments. All tests distinguished between the demented and nondemented groups, but best discrimination was achieved with the S-IMC, which correctly classified 98% of subjects. This version was also the best predictor of functional disability, as measured by impairments in instrumental activities of daily living. Within the normal comparison group, neither gender nor a subject's monolingual/bilingual status affected test performance. These four Spanish-language cognitive screening tasks may aid in the evaluation of dementia among Spanish-speaking patients.
