Idiopathic Parkinson's disease (IPD) is a progressive neurodegenerative disorder affecting approximately 1% of the population above 65 years of age. The aim of this study was to define the estimated Danish IPD population and to elucidate source of income and labour market affiliation for working-age IPD patients.
IPD cases were included through the Danish Register of Medicinal Product Statistics. The participants had to be alive by the end of 2010 and at least twice have cashed in prescriptions on IPD medication in the 2009-2010 period. Information on employment status and transfer income was retrieved through the DREAM database under the Danish Ministry of Employment.
A total of 7,033 estimated IPD patients were identified. The mean age at time of registration (2010, week 50) was 72 years. Overall, 7% of the IPD patients were employed and 5% were self-supportive. In the working age range (18-64 years), 25% were employed and 10% enrolled in supported employment. Compared with the age-adjusted general population, twice as many IPD patients were outside the ordinary labour market and, furthermore, the proportion receiving anticipatory pension was increased threefold. The majority (89%) of the patients were living at home with a spouse (59%). 11% were nursing home residents.
The working age IPD population was more prone to be outside employment and to receive public transfer income than an age-adjusted population sample.
The study was funded by the Danish Parkinson Association.
