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

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.
