“…Discrepancies between patient and caregiver responses may be due to overestimates by overburdened caregivers making for different objective and subjective evaluations. 40 The performance of our AD patients corroborates Duke & Kaszniak findings 3 on deficits in the three components (planning, intentional action and effective performance) for EF 6 in the early stage of the pathology, whereas volitional capacity relates to progression of the disease, and is initially less severe.…”

Objective: Ecological tests are useful in assessing executive function deficits and may be of value in appraising response to treatment in Alzheimer's disease patients. Our aims were to examine executive function using the Behavioral Assessment of the Dysexecutive Syndrome for a Brazilian sample of older-adult controls and probable early Alzheimer's disease patients, and verify the applicability of this test battery. Method: Forty-one older-adult controls were matched with mild Alzheimer's disease patients by age, education, and gender. Results: There significant inter-group differences in overall profile and almost all subtests except temporal judgment, time spent on planning the first and second Zoo Map visit, number of errors when copying drawings, naming pictures and Six Modified Elements arithmetic, and dysexecutive questionnaire self-rating. The Behavioral Assessment of the Dysexecutive Syndrome item that best discriminated controls from patients was the Modified Six Elements -adapted (general index), with a sensitivity of 80% and specificity of 90%, (AUC = 0.91, p < 0.001). Conclusion: Behavioral Assessment of the Dysexecutive Syndrome was effective in detecting executive function deficits in mild Alzheimer's disease patients, particularly the task switching, time monitoring, and rule-shift subtests.

“…These results provide evidence supporting a mechanism in which burden related to taking care of people with dementia may lead to more negative caregiver ratings of the patients health [4,9]. This variability is not specific of anosognosia and has been found in several other caregiver ratings including functional capacities [4,21,22], neuropsychiatric symptoms [4,21,23], and quality of life [4,24,25]. Caregiver AQ-D ratings were not consistently associated with caregiver depression.…”

Abstract.Background: According to cross-sectional studies, there is an association between anosognosia in people with dementia and caregiver's burden and depression. Anosognosia in patients may be a cause of caregiver burden and depression. However, variability in caregiver anosognosia ratings may exist as caregivers with burden and depression may have a more pessimistic view of the patients' health. Objective: To assess the variability of caregiver anosognosia ratings of patients with dementia using a widely used anosognosia scale and its longitudinal relationship with caregiver burden and depression. Methods: A convenience cohort of 221 consecutive dementia outpatient and caregiver dyads was followed up at 12 and 24 months. The main instruments used were the Anosognosia Questionnaire-Dementia (AQ-D), Caregiver Burden Interview, and Geriatric Depression Scale. Linear mixed models were used including time as a factor in every model. Multivariate analyses controlled for caregiver's socio-demographic and possible confounding factors. Results: Attrition at 12 and 24 months was 24.9% and 42.5% respectively. Patients at baseline were on average 77.8 years of age, 63.3% were women, and 63.3% had < 5 years of education. In the bivariate analyses, caregiver burden, depression, and gender were associated with caregiver ratings of total, cognitive, and personality AQ-D of the patient at different time points. Multivariate analyses revealed burden as the caregiver variable most consistently associated with total, cognitive, and personality caregiver AQ-D ratings of the patient. Conclusion: Some caregiver characteristics, especially burden, are associated with caregiver ratings of AQ-D with regard to the patient.

“…We argue that this bias can be attributed to the demanding situation to which caregivers are exposed; caring for a person with dementia is associated with physical, emotional, economical, and social costs. According to Zanetti et al (1999), caregivers' judgments were especially influenced by demands and restrictions on their time. There are several possible reasons for an association between caregiver rating bias and burden.…”

“…Similar results were reported in studies on dyadic rating discrepancies in rating activities of daily living (ADL). Some researchers reported caregiver burden to be associated with the discrepancy scores (Schatzberg et al, 1998;Zanetti et al, 1999;Clare et al, 2011), although only Zanetti et al (1999) assessed both caregiver burden and depression. In contrast, Argüelles et al (2001) showed that caregiver depression but not burden was related to caregiver rating bias.…”

Background: Caregivers of individuals with dementia are biased in their rating of mental health measures of the care receiver. This study examines caregiver burden and depression as predictors of this bias for mild cognitive impairment and mild Alzheimer's disease in different domains. Methods: The sample consisted of 202 persons: 60 with mild cognitive impairment, 41 with mild Alzheimer's disease, and 101 caregivers. Discrepancy scores were calculated by subtracting the mean caregiver score from the respective mean patient score on the following assessment instruments: the Geriatric Depression Scale, Apathy Evaluation Scale, Bayer-Activities of Daily Living Scale, and Quality of Life-AD scale. Caregiver burden and depression were assessed by the Zarit Burden Interview and the Center for Epidemiologic Studies Depression Scale. Results: Intraclass correlation coefficients were low for apathy (0.38), daily functioning (0.38), and quality of life (0.30) and moderate for depression (0.49). These domains showed negative rating discrepancies, which indicates caregiver rating bias for all four domains. Regression analyses revealed that caregiver burden significantly contributed to explaining these discrepancies in the domains apathy, daily functioning, and quality of life. Conclusion: Caregiver rating bias can be attributed to caregiver burden. When caregiver burden is present, data based on caregiver ratings should therefore be interpreted with caution.
