Differences between physician and caregiver evaluations in Alzheimer's disease.

In Alzheimer's disease (AD) differences are often reported between caregivers' and physicians' aims and evaluations. The aim of this study was to investigate the presence of discrepancies between the evaluations of caregivers and physicians. Two hundred and eighteen caregivers of outpatients diagnosed with mild-to-moderate AD, referred to our Alzheimer's Disease Assessment Unit, entered the study. Caregiver burden was investigated using the Caregiver Burden Inventory (CBI) and the Neuropsychiatric Inventory Caregiver Distress Scale (NPIDS). Caregivers were also administered a four-point scale to assess quantitatively whether their expectations in relation to the efficacy of the pharmacological treatment had been satisfied and a scale exploring clinical global impression of change. Caregivers whose expectations had not been satisfied had significantly higher CBI and NPIDS scores and a lower level of education; moreover, caregivers tended to overestimate the degree of cognitive decline during the course of the disease. These results underline the importance of correct and constant communication with AD patients and their families.
