There is a growing need for methods for measuring and staging the natural history of dementia of the Alzheimer type. One instrument, designed with that purpose in mind, is the Washington University Clinical Dementia Rating. We tested its reliability using multiple clinicians in a videotape-design study, and it proved reliable under these study conditions.
