Head injury is a common presentation to the paediatric ED. Most children don't require a CT and can be sent home with advice on when to return (if they develop any signs of raised ICP). But how long will it take to recover? This is an important question, particularly if the child has important exams (or a vital football match) coming up. The literature to date (mainly small retrospective studies) is all over the place on this question, with expected recovery time ranging from days to years. This paper is the first large prospective study to investigate this.
