Determinants of disability and quality of life in mild to moderate Parkinson disease

Abstract

Axial impairment is strongly associated with disability in patients with mild to moderate Parkinson disease (PD). Self-report indices of mood status and axial impairment are identified as the main determinants of poor quality of life (QoL). The results of this study may help to identify patients with PD at risk for functional dependence and reduced QoL.
