Behavioural disorders, disability and quality of life in Parkinson's disease

摘要

Background: although non-motor symptoms of Parkinson's disease (PD) are known to adversely affect disability and health-related quality of life, the impact that specific disorders of reward and motivation have remains unclear. Impulse control disorders are more likely in those with a younger disease onset although there is no strong evidence to date that apathy is related to age of onset or correlated with a longer duration of disease.
