Liou YJ, et al. - Using the Taiwan National Health Insurance Research Database, researchers explored the association between attention-deficit hyperactivity disorder (ADHD) and the risk of traumatic brain injury (TBI). Between 2001 and 2009, 72,181 children (aged 3–11 years), adolescents (12–17 years), and young adults (18–29 years) with ADHD and 72,181 age-/sex-matched controls were recruited and followed up to the end of 2011 for this investigation. Researchers reported that children, adolescents, and young adults with ADHD had an increased risk of developing any TBI such as skull fracture and concussion vs controls. Findings suggested that long-term use of ADHD medication was linked with a decreased probability of subsequent TBI. Public health government and clinicians need to pay more attention to TBI risk among patients with ADHD and finding the optimal treatment for ADHD.
