The number of persons with Parkinson Disease (PD) in the United States is expected to double by 2030 as the population ages. Importantly, this increase in the prevalence of PD will have greater impact within the Department of Veterans Affairs (VA) because the Veteran population is older than the general population and Veterans with PD are more likely than those without PD to rely solely on VA for their health care. While PD is often characterized by the motor symptoms of the disease (tremor, bradykinesia, rigidity), non-motor symptoms such as urinary symptoms correlate more closely with impaired well-being as the disease progresses. However, the impact of urinary symptoms in PD extends beyond worsened well-being. The urinary symptoms of overactive bladder (OAB), including urgency, frequency, and nocturia, with or without urinary incontinence, are the most common urinary symptoms of PD. OAB symptoms are associated with falls (a cause of increased mortality in PD), with spouse/caregiver stress, and, ultimately with institutionalization, thus it is critical that we optimize the care of urinary symptoms for Veterans with PD.
