The economic impact of Parkinson's disease

Patients with Parkinson's disease (PD) experience progressive disability and reduced quality of life due to both motor and non-motor complications. The cost of illness escalates as PD progresses, placing an economic burden on the healthcare system, society and patients themselves. Overall cost estimates vary from country to country, but the largest component of direct cost is typically inpatient care and nursing home costs, while prescription drugs are the smallest contributor. Indirect costs arising from lost productivity and carer burden tend to be high. The total cost in the UK has been estimated to be between 449 pound million and 3.3 pound billion annually, depending on the cost model and prevalence rate used. Management strategies that minimise the impact of disease progression and maximise quality of life should help ensure optimal resource utilisation. (C) 2007 Published by Elsevier Ltd.
