Association of Dementia Severity at Diagnosis With Health Care Utilization and Costs Around the Time of Incident Diagnosis.

ABSTRACT:

This study provides the first analysis of heterogeneity in health care use and costs by level of dementia symptom severity around the time of incident dementia diagnosis for a population-representative sample of older Americans.
