Abstract
Objective: Parkinson's disease (PD) is a neurodegenerative movement disorder that is a result of dopamine depletion in the basal ganglia. Individuals with a PD diagnosis experience motor symptoms (e.g., tremors) and nonmotor symptoms (e.g., cognitive decline). Previous studies suggest that progression of cognitive dysfunction in other neurologic populations can be predicted by cumulative head injuries. The study examined the association between lifelong number of head injuries and nonmotor outcomes (cognitive complaints, depression, and quality of life).
Methods: Participants consisted of 3,483 individuals with PD diagnoses who were enrolled in the Fox Insight study. Participants completed a self-report questionnaire to quantify the number of head injuries experienced throughout life. Participants also completed measures of nonmotor outcomes (cognitive complaints, depression, and quality of life) every 6 months over a 3-year period.
Results: Cognitive complaints were more common among those experiencing more head injuries. Further, more severe depression and greater difficulties in quality of life were reported among individuals experiencing a greater number of head injuries. Additional analyses revealed the effect between cognitive complaints and number of head injuries was driven by individuals who experienced five or more head injuries in their lifetime.
Conclusions: Among individuals with PD, a patient report of past head injuries may have prognostic implications for important nonmotor outcomes. Report of multiple head injuries may be particularly concerning.
期刊介绍：
As the official Journal of the American Neuropsychiatric Association, the premier North American organization of clinicians, scientists, and educators specializing in behavioral neurology & neuropsychiatry, neuropsychology, and the clinical neurosciences, the Journal of Neuropsychiatry and Clinical Neurosciences (JNCN) aims to publish works that advance the science of brain-behavior relationships, the care of persons and families affected by neurodevelopmental, acquired neurological, and neurodegenerative conditions, and education and training in behavioral neurology & neuropsychiatry. JNCN publishes peer-reviewed articles on the cognitive, emotional, and behavioral manifestations of neurological conditions, the structural and functional neuroanatomy of idiopathic psychiatric disorders, and the clinical and educational applications and public health implications of scientific advances in these areas. The Journal features systematic reviews and meta-analyses, narrative reviews, original research articles, scholarly considerations of treatment and educational challenges in behavioral neurology & neuropsychiatry, analyses and commentaries on advances and emerging trends in the field, international perspectives on neuropsychiatry, opinions and introspections, case reports that inform on the structural and functional bases of neuropsychiatric conditions, and classic pieces from the field’s rich history.
