Dementia caregiver burden in a Brazilian sample: Association to neuropsychiatric symptoms

Abstract Taking care of elderly demented individuals, especially when they present behavioral changes, can be very exhaustive for both family and caregivers. Generally, this leads to changes in the family lifestyle, and the caregiver must deal with a range of problems. Information on this topic in Latin America, including Brazil, remains scarce. Objective: To investigate the relationship between the presence of neuropsychiatric symptoms and the level of caregiver burden in a group of Brazilian elderly with dementia. Methods: The Brazilian versions of the Zarit Caregiver Burden Interview (ZBI) and of the Neuropsychiatric Inventory (NPI) were administered to a total of 83 family-caregivers of patients with dementia followed at a university-affiliated outpatient clinic. Pearson's correlations were calculated to measure the level of association between the scores on both instruments. Results: Among the caregivers, 83.1% were women, and had a mean age of 55.6±12.8 years. The ZBI scores ranged from 3 to 79 (mean=31.4). Patients' NPI scores ranged from 0 to 102 (mean=26.9), consistent with a significant degree of behavioral manifestations in most patients. A significant positive correlation was found between ZBI and NPI scores (r=0.402; p=0.000). Conclusion: The presence and severity of behavioral manifestations assessed by the NPI were associated with a high level of caregiver burden in this sample of Brazilian elderly with dementia

Positive effects of a cognitive-behavioral intervention program for family caregivers of demented elderly

OBJECTIVE: It was to examine the effects of a Cognitive-Behavioral Therapy (CBT) program administered to family caregivers of dementia patients. METHODS: Forty family caregivers were enrolled in a CBT intervention across eight weekly sessions. Cognitive, functional and behavioral status of patients were evaluated, as well as their own and their family caregivers' perceptions of quality of life. Specific instruments were also applied to evaluate caregiver stress level, coping, anxiety and depression. RESULTS: At the end of the program, family caregivers reported fewer neuropsychiatric symptoms among patients and an improvement in patients' quality of life. In addition, caregivers changed their coping strategies, whereas a significant decrease was observed in their anxiety levels. CONCLUSION: The CBT program employed appears to be a promising and useful tool for clinical practice, displaying positive effects on quality of life and neuropsychiatric symptoms of dementia, as well as proving beneficial for alleviating anxiety and stress in family caregivers
