Head injuries and ADHD

Some studies have suggested that injury is more common in children with Attention Deficit Hyperactivity Disorder (ADHD) while others have suggested that moderate-to-severe traumatic brain injury in school-age children results in the development of ADHD. A UK study of 62,088 children compared those (2,782) who had suffered a head injury, those (1,116) who had suffered burns and the remainder who had suffered neither. Children who had had head injuries were 1.9 times as likely to develop ADHD while children who had suffered burns were 1.7 times more likely to develop the condition.
