The contribution of neuropsychiatric symptoms to the cost of dementia care

OBJECTIVE: To estimate the contribution of behavioral and psychological symptoms of dementia (BPSD) to the costs of care. METHOD: A one-year prospective study of resource utilization recorded monthly by 500 caregivers of community dwelling patients with dementia. The effect of behavior on total, direct and indirect costs of care was examined. RESULTS: The total cost of care was $1,298 per month and there was a significant independent relationship between costs and BPSD. The incremental cost of a one point increase in Neuropsychiatric Inventory score was $30 per month (95% CI: $19-$41). CONCLUSION: BPSD contribute significantly to the overall costs of dementia care. Interventions targeted at BPSD may help to reduce the staggering societal costs of this illness.
