Clinical Dementia Rating (CDR) Scale
The following is an excerpt from the Washington University in St. Louis Alzheimer's Disease Research Center's website: www.adrc.wustl.edu
The CDR is a 5-point scale used to characterize six domains of cognitive and functional performance applicable to Alzheimer disease and related dementias: Memory, Orientation, Judgment & Problem Solving, Community Affairs, Home & Hobbies, and Personal Care. The necessary information to make each rating is obtained through a semi-structured interview of the patient and a reliable informant or collateral source (e.g., family member).
