Young children who are hospitalized with head injuries may be at higher than average risk for developing attention deficit hyperactivity disorder (ADHD) later on, a small study suggests.
U.S. researchers examined data on 187 children, including 81 who were hospitalized overnight for a traumatic brain injury (TBI) at some point from age 3 to 7, and 106 who were hospitalized with other injuries. None of the kids had ADHD at the start.
Altogether, over the next seven years, 48 children, or 26 percent, developed symptoms of ADHD. Children with TBI were more than three times as likely to develop ADHD as kids with other kinds of injuries.
