The Many Faces of Parkinson's Disease

The total cost of Parkinson disease (PD), which affects nearly 1 million people in the US is $52 billion every year, with $25.4 billion attributable to direct medical costs such as hospitalizations and medication, and $26.5 billion in non-medical costs like missed work, lost wages, early forced retirement, and family caregiver time. The more we know about PD's non-motor symptoms-depression, dementia, fatigue, and others-the better we can treat, and perhaps find a cure, for this neurological disorder.
