ABSTRACT
Introduction: Parkinson’s disease (PD) causes progressive motor symptoms including tremor, rigidity, and bradykinesia, along with non-motor symptoms such as dementia, orthostatic hypotension, and depression. Over time, PD can lead to falls, disability, institutionalization, and caregiver burden. Its treatment is symptomatic and can be associated with high costs.
Areas covered: The authors performed a literature search of PubMed, Web of Science, and Cochrane Library Current for English language PD pharmacoeconomic evaluations starting from 1 January 2000. The authors found 26 papers covering treatment of motor symptoms (n = 24), dementia (n = 1), and orthostatic hypotension (n = 1). The scope of literature was limited in that there were few articles overall.
Expert opinion: Overall, the authors found a scarcity of primary PD pharmacoeconomic literature in the 21st Century. Given the myriad of PD motor and non-motor treatments, only 24 papers evaluating motor treatments and two papers evaluating non-motor treatments met our search criteria. More studies are clearly needed to better define the pharmacoeconomics of PD therapeutics.

Article Highlights
PD is a prevalent neurological condition, and its treatment incurs a large medical and societal cost
The scope of pharmacoeconomic literature in PD since 2000 is limited, particularly for the treatment of non-motor features of PD
Most of the studies that met our inclusion criteria were industry funded, and a majority of results favored cost-effectiveness of the product being studied
Modeled cost analyses can be problematic because adjustment of the parameters that are studied can lead to differing results
There is little standardization in health utility values within the context of PD
