The Milan Overall Dementia Assessment and the Mini‐Mental State Examination compared: an epidemiological investigation of dementia

Abstract

We assessed the validity of two screening tests [the Mini-Mental State Examination (MMSE) and the Milan Overall Dementia Assessment or (MODA)] in a population study on the prevalence of Alzheimer's disease, carried out in a small town in the north of Italy. A random sample of 1000 subjects aged 60 years or over entered the study. Subjects who scored below the cut-off points on MODA or on MMSE, or both, were further investigated with neuropsychological, laboratory and instrumental tests to ascertain a final diagnosis, which was considered as the gold standard. Our findings show that MODA has a higher sensitivity than MMSE in detecting subjects affected by dementing illnesses, while MMSE shows a higher specificity. MODA seems to be preferable to MMSE as a screening test for studies where a very high sensitivity is required.
