Abstract
Background & Objectives: Although it is important to study the association between caregiver burden and individual with dementia, a little has been paid attention to this issue in Iranian population therefore the aim of study was to investigate the frequency of psychiatric symptoms and patients with dementia and caregiver burden associated with individual with dementia.Methods: In this study 84 patients who had referred to Iran Alzheimer’s Association, along with their caregivers were included in our study. Iranian Version of Caregiver Burden and NPI questionnaires were employed. Factors affecting factors on burden was analyzed by multivariate linear regression. Results: Our findings showed that there was at least one psychiatric disorder in all patients. Among all psychiatric symptoms delusion and elation had the highest and lowest rates with 39.3 and 2.4 percentages, respectively. Linear regression indicated that “indifference” and “irritability” symptoms were the effective psychiatric symptoms on the amount of burden placed on the caregivers. Conclusion: The symptom frequency of irritability and other symptoms showed a statistically significant positive correlation with caregiver's NPI-D score. These findings suggest that improvement of treatments for delusions, irritability among dementia patients may reduce caregiver burden.
