When to Use

Staging dementia severity for clinical management and care planning.

Research and clinical trials — CDR Sum of Boxes (CDR-SB) is a primary outcome in Alzheimer's disease trials.

Longitudinal monitoring of dementia progression over months to years.

Hospice and advanced care planning — CDR 3 (severe) supports 6-month hospice eligibility.

Staging vs. Screening

The CDR is a staging tool, not a screening tool. It requires structured clinician interview of both the patient and a knowledgeable informant and takes 20–40 minutes. Use Mini-Cog, MoCA, or AD8 for initial screening; use CDR when diagnosis is established and staging is needed.

Related Scores in Practice

In clinical practice, this assessment is frequently evaluated alongside other validated measures. Depending on the patient's presentation and specific diagnostic requirements, you may also need to utilize the MMSE, MoCA, AD8 Dementia Screening or the FAST Scale (Dementia) to formulate a comprehensive care plan.
