Longitudinal evaluation of economic and physical impact of Parkinson's disease.
The cost of parkinsonism and Parkinson's disease (PD) is largely unknown although clinical experience suggests that the impact of this disease is substantial. Longitudinal data is presented for health status, disease symptoms, functional status, and financial costs for 70 participants with PD or parkinsonism. The sample was dichotomized into those rating their health as excellent, good, or very good ('good health') and those rating their health as fair or poor ('poor health'). The 'poor health' group were significantly more disabled at baseline. Symptoms increased between year 1 and 3 with greatest increases in fatigue, pain, and depression for the 'good health' group. At year 1, total direct cost/capita was about dollars 5000/year for both groups; indirect costs were dollars 5000 for the 'good health' group and dollars 15,000/year for the 'poor health' group. By year 3, total expenditures increased over 25% for the 'good health' group and nearly doubled for the 'poor health' group, while percent costs that were compensated declined for groups. Out of pocket, expenses were as high as dollars 3000/year for the 'poor health' group by year 3. Through analysis of the broad impact of PD, including non-neurological symptoms and economic ramifications, it is possible to better appreciate the impact of this chronic condition on overall quality of life.
