PRIMARY OBJECTIVE: To determine whether neuropsychological test performance or affective factors predict long-term post-concussive symptoms and cognitive complaint following mild traumatic brain injury. METHODS AND PROCEDURES: Participants included 21 individuals with mild traumatic brain injury, 19 individuals with spinal injury but no injury to the brain and 20 neurologically-normal controls. All participants completed measures of post-concussive symptoms, cognitive complaint, depression, anxiety, and personality and were administered a variety of neuropsychological tests. MAIN OUTCOMES AND RESULTS: The hypothesis that depression, anxiety and neuroticism would be better predictors of post-concussive symptoms than neuropsychological test performance for all three groups was supported. Contrary to expectations, however, neuropsychological test performance was a unique predictor of cognitive complaint for the mild traumatic brain injury group. CONCLUSIONS: It was concluded that long-term post-concussive symptoms are largely representative of psychological symptoms and not brain damage, but that genuine, albeit subtle, cognitive deficits also may be present for long-term periods following mild traumatic brain injury.
