Objective Although the clinical course of Alzheimer disease (AD) is gradual, it is useful for a
number of reasons to distinguish between different levels of severity. The Clinical Dementia
Rating (CDR) has demonstrated high validity and reliability for this purpose, but it requires a
considerable amount of data to be collected both from the patient and from an informant. In
the present study, the authors mapped Mini-Mental State Examination (MMSE) scores onto
CDR categories to determine how well the MMSE performs as a surrogate of the CDR as a …
