Health related quality of life in Parkinson's disease: a prospective longitudinal study

Abstract

Parkinson's disease has a substantial impact on HRQL. Despite modern care, we found a significantly increased distress during the 4 year follow up period. Increased parkinsonism, measured by UPDRS and Hoehn and Yahr stage, correlated with increased stress, not only in the dimension of physical mobility, but also in the areas of pain, social isolation, and emotional reactions. In addition to the clinical examination, HRQL scoring provides valuable information on the total health burden of Parkinson's disease in both cross sectional and longitudinal evaluations, and contributes to a more comprehensive picture of the total disease impact.
