OBJECTIVE: This study aims to determine the relationships between behavioural and psychological symptoms of dementia (BPSD), cognitive impairment and burden of care of patients with dementia. METHOD: A cross-sectional, non-randomised study of 65 elderly patients with dementia and their caregivers was conducted over a 3-month period in January 2007 at the memory clinics of Universiti Kebangsaan Malaysia Medical Centre and Hospital Kuala Lumpur. Patients' cognitive functions were assessed with the Mini Mental State Examination (MMSE). Caregivers were interviewed to determine the severity of BPSD and caregiver burden (CB) using the Neuropsychiatric Inventory (NPI) Questionnaire and Zarit Burden Interview (BI) respectively. RESULTS: Cognitive impairment did not contribute significantly to CB. Multiple linear regression analysis showed that high BPSD scores contributed 0.27 more in BI score, female patients contributed 0.37 less in BI score and caregivers with higher educational level contribute 0.5 more in BI score. CONCLUSION: Patients' BPSD and male gender, but not cognitive impairment, were associated with CB. Even though CB was experienced more among caregivers with better education, all caregivers should be screened to ensure their general well-being.
