The formal care costs of dementia: a longitudinal study using Swedish register data.

Background: This study investigates the excess costs of dementia from healthcare, social care services, and prescription drugs 3 years before to 6 years after diagnosis. Further, sociodemographic cost differences are explored.

Methods: Using Swedish register data from 2013 to 2016 to compare individuals diagnosed with dementia (n = 15,339) with population controls, the excess formal care costs for people with a dementia diagnosis are obtained with longitudinal regression analysis.

Results: People with dementia incur higher formal care costs for all years studied compared to people without dementia. The excess costs vary from €3400 3 years before diagnosis to €49,700 6 years after diagnosis. The costs are mainly driven by institutional care, and solitary living is a strong predictor of high excess costs.

Conclusion: The results show that the formal care costs of individuals with dementia are substantial, and that the economic burden of dementia in Sweden is larger than previously estimated.
