The Importance of Cross-Disciplinary Research: A Commentary on “Brainstem Pathologies Correlate With Depression and Psychosis in Parkinson's Disease”

Published:January 18, 2021DOI:
      Over the past several decades, there has been increasing awareness of and focus on the nonmotor aspects of Parkinson's disease (PD). These include disordered autonomic function, cognitive impairment, and neuropsychiatric features including depression, anxiety, and psychosis. Neuropsychiatric symptoms are common, contribute to PD-related disability, and negatively impact health-related quality of life. In spite of the increasing awareness, these symptoms may still go unrecognized and under-treated due to an inappropriate singular focus on motor symptoms. Compounding this, the current evidence base is insufficient to guide appropriate treatment of psychiatric symptoms in PD. Treatment approaches often reflect those used in the general population, which may not be appropriate given suspected differences in mechanisms. A better understanding of the underlying pathophysiology may inform approaches toward treatment.
