Improved understanding, detection, and management of neuropsychiatric complications: essential components to the optimal treatment of Parkinson's disease

Abstract

It has been well established that Parkinson's disease (PD) is not just a movement disorder (Weintraub and Burn, 2011). Fortunately, the past two decades have seen increased attention to the neuropsychiatric aspects of the disease process. Neuropsychiatric symptoms (e.g., mood, sleep, psychosis, and impulse control) are experienced by the overwhelming majority of people living with PD (PWP) and have a detrimental impact on physical and cognitive decline (Pontone et al., 2016), quality of life (van Uem et al., 2016), and caregiving relationships (Santos-García, 2015). As a field, all multidisciplinary providers involved in the care of PWP, inclusive of movement disorder specialists, geriatric psychiatrists, clinical psychologists, social workers, and other allied healthcare providers, must work to improve the recognition and treatment of key non-motor symptoms, such as depression and anxiety, as part of the standard of care (Cohen et al., 2016). Improved detection and management is critical, as the failure to appropriately treat psychiatric complications negatively impacts the overall course of the illness, functional aspects of daily life, and the PWP ability to fully engage in their own self-care (Pontone et al., 2016).
