Most people with Parkinson’s experience several non-motor symptoms within five years of their initial diagnosis. Like the motor symptoms, the non-motor symptoms of Parkinson’s tend to get worse over time. Drug therapies exist for some non-motor symptoms, often requiring a patient to take a different drug for each treatable non-motor symptom. For other non-motor symptoms, effective drug therapies simply don’t exist. Deep Brain Stimulation, a surgical option for advanced Parkinson’s disease, primarily improves motor symptoms. But a recent study suggests it is the non-motor symptoms that are the greatest burden on people with Parkinson’s and their caregivers (Hermanowicz et al. 2019).
