Young children treated for attention-deficit/hyperactivity (ADHD) disorder performed worse in school and had worse health outcomes, even with medication, a large retrospective study from the U.K. found. These children fared worse academically than their peers without ADHD. They had higher rates of exclusion from school and were more likely to have special needs. They also were at higher risk of low academic attainment and unemployment after leaving school, reported Michael Fleming, MSc, of the University of Glasgow in Scotland, and colleagues. Kids with ADHD were also more likely to be hospitalized both overall and as a result of injury, the authors wrote in JAMA Pediatrics.
