Abstract

BackgroundThe objective of this study was to determine who gets post-concussion syndrome PCS after mild traumatic brain injury or head injury.

MethodsPatients presented within an hour of mild traumatic brain injury mTBI. Written informed consent was obtained from all patients, who then provided detailed answers to surveys at the time of injury as well as at 1 week and 1 month follow-up. Statistical analyses were performed using JMP 11.0 for the Macintosh.

ResultsThe most commonly reported symptoms of PCS at first follow-up were headache 27%, trouble falling asleep 18%, fatigue 17%, difficulty remembering 16%, and dizziness 16%. Furthermore, only 61% of the cohort was driving at 1 week follow-up, compared to 100% prior to the injury.

Linear regression analysis revealed the consumption of alcohol prior to head injury, the mechanism of head injury being a result of motor vehicle collision MVC or fall, and the presence of a post-injury headache to be significantly associated with developing PCS at 1 week follow-up, while the occurrence of a seizure post-injury or having an alteration in consciousness post-injury was significantly associated with developing PCS at 1 month follow-up. On multivariate regression analysis, the presence of a headache post-injury was the most robust predictor, retaining statistical significance even after controlling for age, gender, and presence of loss of consciousness LOC, alteration of consciousness AOC, post-traumatic amnesia PTA, seizure, or vomiting.

ConclusionsThe results of this prospective study suggest that headache right after the head injury, an alteration of consciousness after the head injury, and alcohol consumption prior to the head injury are significant predictors of developing PCS, which occurs with equal frequency in men and women. Early identification of those who are at risk of developing PCS would diminish the burden of the injury and could potentially reduce the number of missed work and school days.
