Neuropsychiatric symptoms as a predictor of caregiver burden in Alzheimeras disease

Aims Patients with Alzheimeras disease need assistance and supervision of their daily activities. They survive for protracted periods of time, placing an extensive burden of care on the caregiver prior to the patientas death. The present study addressed the predictive value of behavior-related burden on Alzheimeras disease caregivers. Participants 82 patients with probable Alzheimeras (73.7 A- 8.1 years), and their primary caregivers (59.6 A- 14.8 years, 81.5% women), were assessed. Methods Cognitive impairment, neuropsychiatric symptoms, and dementia severity were assessed with Mini Mental State Examination (MMSE), Neuropsychiatric Inventory (NPI), and Clinical Dementia Rating (CDR), respectively. Caregivers were given Zaritas Burden Interview and Carer Activity Inventory. Results Neuropsychiatric symptoms like delusions, hallucinations, restlessness, anxiety, euphoria, disinhibition, unusual motor behavior, sleep disturbances, and appetite alterations were the best caregiver burden predictors (NPI r = 0.482, p & 0.001). No correlation with cognition, disease stage, or negative neuropsychiatric symptoms (depression and apathy) was found. Conclusion Increased caregiver burden was related to increased levels of patient behavioral disturbance. Of these symptoms, hallucinations, unusual (motor) behavior, and abnormal behavior at nighttime were the most significant. No correlation with neuropsychiatric symptoms such as apathy and depression was found. This may have relevance to appropriate interventions for caregivers.
