Undetected attention deficit-hyperactivity disorder (ADHD) was not uncommon among adults hospitalized after traffic accidents, according to a cross-sectional study from the Dominican Republic.

Among 95 adults admitted for traffic-related injuries without a prior diagnosis, more than a third (34.7%) screened positive on the Adult ADHD Self-Report Scale, reported Amanda Abreu, MD, of the Universidad Iberoamericana in Santo Domingo, Dominican Republic.
