Predictors of driving cessation, independent living, and power of attorney decisions by dementia patients and caregivers

Abstract

This study examines factors associated with decisions made by dementia patients and their caregivers regarding whether the patient should cease driving, live alone or with their spouse, and assign a Durable Power of Attorney. Using data collected by the Alzheimer's Disease Research Center (ADRC) in the Memory Disorders Clinic at the University of Kentucky Medical Center, we analyzed 827 first visits to predict patients’ and caregivers’ decisions. Caregiver relationship and patient gender and perceptions of patient abilities, as measured by Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs) were more important than cognitive functioning, as measured by the MMSE, in predicting decisions made. These findings have theoretical implications for modeling the impact of the course of the disease and practical implications for interventions aimed at supporting the decision-making processes of patients and caregivers.
