Mild head injury and attention deficit hyperactivity disorder in children.

Purpose: Post-concussion syndrome is a well-described complication following moderate and severe head trauma but whether it occurs after mild head injury in children remains unclear. The aim of this study was to evaluate whether exposure to mild head injury with potential additional risk factors (non-surgical lesion on computed tomographic, high kinetic trauma, or Glasgow Coma Scale <15) is associated with attention deficit hyperactivity disorder (ADHD) after the head trauma.

Methods: This study was performed in an emergency department on children admitted between 2009 and 2013.
