Quality of life in Polish patients with long-lasting Parkinson's disease

Abstract

The objective of this study was to evaluate possible relationships between quality of life (QoL) of Polish patients with long-lasting Parkinson's disease and various demographic and clinical factors. The study comprised 141 patients of Movement Disorders outpatient clinics in Warsaw and Gdansk with at least 5 years of the disease duration. Mean age of patients was 68.09 +/- 8.51 years, mean duration of disease was 11.87 +/- 5.14 years. To assess the quality of life, the Parkinson's Disease Questionnaire (PDQ-39) was used. Additional questions concerned duration of disease, initial and current treatment and expenses associated with therapy. Self-perceived symptoms of depression were in our study the most important factor determining QoL. Duration of the disease and expenses related to the treatment also have a significant impact on the QoL. Patient's age and presence of dyskinesia seem to be irrelevant to the quality of life.
