Non-motor symptoms (NMS) have emerged as a key component of Parkinson’s disease (PD) and their importance ranges from being clinical biomarkers in the pre-motor phase of PD to a range of symptoms that accompany the whole journey of a person with PD. The overall burden of NMS has now been shown to be one of the defining constituent of health-related quality of life of people with PD. In addition, NMS also substantially increase the overall cost of care of PD and lead to increased hospitalization and also institutionalization in the late stage of PD. However, effective, evidence-based treatment of NMS remains an unmet need and poses one of the biggest challenges to healthcare professionals dealing with PD. In the clinic, NMS are often overshadowed by the dominance of motor symptoms and low awareness of these among treating healthcare professionals.
