AbstractPediatric traumatic brain injury is a significant public health concern affecting hundreds of thousands of children each year. The majority of children who sustain traumatic brain injuries are classified as having a mild traumatic brain injury, and a subset of these children go on to experience persistent physical, cognitive, and emotional symptoms. These symptoms, known as postconcussive symptoms, can endure for months and even years after injury. The outcomes of mild traumatic brain injury are variable and not well understood for a small percentage of children who experience persistent symptoms. The current article explores the potential influence of children's posttraumatic stress symptoms on persistent postconcussive symptoms. Despite the high incidence of posttraumatic stress symptoms after pediatric accidental injury, they have not yet been identified as an important factor for consideration in the understanding of pediatric postconcussive outcomes. The article will review the literature on posttraumatic stress and postconcussive symptoms after pediatric injury and consider neurobiological and cognitive factors to propose a model explaining a pathway through which posttraumatic stress reactions may serve as the mechanism for the expression and maintenance of postconcussive symptoms after mild traumatic brain injury. The clinical implications for the proposed relationship between posttraumatic stress symptoms and postconcussive symptoms are considered prior to the conclusion of the article, which acknowledges limitations in the current literature and provides suggestions for future research.
