Multimorbidity Predicts Quality of Life but not Motor Severity in Early Parkinson's Disease.

Recent guidance by the National Institute for Health and Care Excellence (NICE) focuses on the management of people with multimorbidity, including Parkinson's disease (PD). To date there has been little exploration of this in neurodegenerative diseases. This study aimed to explore the associations between multimorbidity, motor severity and quality of life (QoL) in early PD. Regression analyses determined whether multimorbidity was significantly associated with disease severity and QoL. Multimorbidity was a small but significant predictor of QoL in people with incident PD, but not motor severity, suggesting that they may benefit from a tailored multidisciplinary approach to care.
