COPENHAGEN, Denmark, Aug. 27, 2023 /PRNewswire-PRWeb/ — In a study of nearly 360,000 military veteran records released earlier this year in the Movement Disorders journal, researchers provide evidence that traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD), both trauma-related disorders, are risk factors for Parkinson’s disease (PD).
While this correlation has long been suspected, the results of this study validate the hypothesis with the researchers’ case-controlled approach and consideration of comorbidities. This study further suggests that these common war-related illnesses may ignite biochemical changes that precede and fuel the development of Parkinson’s disease decades later.
“While a link between head trauma and the later emergence of Parkinson’s has been widely accepted for some time, this paper is of interest for several reasons,” said Dr. Jon Stoessl, University of British Columbia and editor of the Movement Disorders Journal. “Similar to a prior report (White et al., Ann Neurol 2020), the authors have identified an independent and synergistic link between PTSD and PD. They examined a large cohort (nearly 72,000 cases and nearly 290,000 matched controls from the VA database), used a minimum lag time of 5 years between exposure and PD diagnosis, and have gone back as long as 60 years prior to the emergence of PD. Applying an unusual degree of rigor for this type of research, the authors ascertained a diagnosis of PD based on chart review by a movement disorders specialist in addition to administrative (diagnostic code and prescription) data. They furthermore restricted the definition of TBI and PTSD to events that occurred during active military service. The odds ratio (OR) for PD in those with TBI range from 1.5-2.0 (depending upon time of exposure) and for PTSD, the OR was 1.7-1.8. The findings not only confirm the importance of earlier TBI as a risk factor for later PD, but also point to the independent and synergistic importance of PTSD in future neurodegeneration. The findings thus have important implications for understanding the pathogenesis of PD and for the consideration of novel preventative and disease modifying approaches.”
