Longitudinal Study on the Relationship Between Symptomatology of Dementia and Levels of Subjective Burden and Depression Among Family Caregivers in Memory Clinic Patients
The objective was to evaluate the course and severity of dementia-related symptoms and their relationship to caregivers’ subjective burden and depression over time. Forty-five patients with dementia and their caregivers were followed over a period of 2 years. Patients’ cognition, function, and behavioral/psychological symptoms were assessed by the Mini Mental State Examination, Syndrome Kurz Test, Geriatric Depression Screening scale, Instrumental Activities of Daily Living Scale, Physical Self Maintenance Scale, Behavioral Abnormalities in Alzheimer’s Disease Rating Scale, and Nurses Observation Scale for Geriatric Patients. Caregivers’ depression and subjective burden were evaluated by the Geriatric Depression Screening scale or Beck Depression Inventory and the Caregiver Burden Interview. Global dementia severity, functional impairment, and behavioral disturbances increased significantly over the 2-year observation period. Caregivers’ burden remained stable, and severe depression decreased over time. There were significant associations between burden and dementia-related symptoms. For deficits in activities of daily living as well as behavioral disturbances, these associations became stronger over time. It was concluded that stage of dementia, functional deficits, and behavioral disturbances are important factors when evaluating the relationship between patients’ symptoms and caregivers’ well-being.
