Relative contribution of comorbid diseases to health-related quality of life in patients with Parkinson's disease.

ABSTRACT:

Background

Multimorbidity is common in elderly people, and one of the major consequences of multimorbidity is low health-related quality of life (HRQoL). The aim of this study was to investigate the frequency of comorbid diseases in patients with Parkinson's disease (PD) and to analyze their relative importance in HRQoL. The aim was also to examine agreement between the generic 15D questionnaire and the PD-specific Parkinson's Disease Questionnaire (PDQ-8) to further validate 15D in the evaluation of HRQoL in patients with PD.

Methods

Patients with PD (N = 551) filled a questionnaire on comorbid diseases, and the 15D questionnaire yielding a 15-dimensional health profile and a score representing the overall HRQoL. Self-organizing map was used for an unsupervised pattern reco
