[Mild head injury].

Introduction: Mild traumatic brain injury (TBI) represents a major health concern, because a sizeable number of patients with mild TBI will develop potentially life-threatening complications. The target of this study was to describe a large series of adult patients suffering from mild TBI, treated at University Hospital of Getafe, between 2010 and 2015 ( = 2480). We examined the patients' epidemiological and baseline clinical profile, diagnosis, treatment and ultimate outcomes, to identify major prognostic factors that influence the final result.
