Diagnosis Threat in Mild Traumatic Brain Injury
Persistent neurocognitive complaints in concussion are thought to be more likely due to non-neurological factors. The present study explored diagnosis threat, a subtle expectation-based theory of lowered neuropsychological performance in a group of concussed or mild traumatic brain injured (MTBI) students. Participants were 32 healthy, asymptomatic, non-litigating students with a history of MTBI at least six months previously. They were randomly assigned to view either a video with negatively framed information about MTBI or a video unrelated to brain injury. Students completed tests of visual and verbal memory, visual and verbal information processing, attention, working memory, and processing speed. Participants were unaware that the study was related to MTBI or that they were selected because of their MTBI history. Contrary to expectations, no differences in cognitive performance were found based on video viewed. Ultimately, this study is limited by small sample size along with potentially less effective activation of diagnosis threat.
