I want to find patients with a mild dementia diagnosis, excluding those with moderate dementia or nondemented status, using the Clinical Dementia Rating (CDR) measure from the OASIS clinical measures, between the dates of December 1, 1979 and September 24, 2020, with a specificity scale of 0 and an accuracy scale of 100.
