Memory versus intelligence in dementia screening--MMSE.
The Mini-Mental State exam is a widely used screening instrument for dementia. Recent research has suggested that errors in classification reported for this instrument may be due to premorbid levels of intelligence and education, Thirty-one ambulatory patients diagnosed with Alzheimer's disease were administered a standard neuropsychological testing battery. MMSE scores and intelligence are significantly correlated. However when memory ability is partialed out, the covariance of MMSE and intellectual abilities does not add any further information to that already provided by the memory scores.
