Unmet needs in Parkinson disease: Motor and non-motor.

Abstract

Compared to other neurodegenerative diseases, Parkinson's disease (PD) is distinctive in terms of marked symptomatic variability and prognosis, as well as for the wide variety of symptomatic treatment options. Despite several decades of advances in medications and neurosurgical approaches, there remains an unmet need for symptomatic motor control. Better control of tremor, gait and balance, posture, dexterity, and communication skills are major challenges for better therapeutics of the PD movement disorder. Non-motor symptoms (NMS), which often precede motor impairments, add complexity to the burden of PD and its management. Recognized by James Parkinson MD two centuries ago, and despite 21st century neurological advances, a range of NMS plague the patient's journey, from prodromal to palliative stages. Characterizing the clinical phenotype of the entire non-motor profile of PD is challenging. Further research and understanding are needed for discovering biomarkers of certain NMS, such as dementia, fatigue, pain, sleep, and apathy. More work is needed to gather a robust evidence base for guiding treatment of troubling NMS, which exert a major impact on quality of life for people with PD and their caregivers.
