Many ADHD Kids Also Have Reading Problems Sept. 24, 2010 -- About half of children with attention deficit hyperactivity disorder (ADHD) may experience problems with reading, according to a new study in Pediatrics.

The National Institute of Mental Health estimates that 3% to 5% of children have ADHD, a behavioral disorder marked by difficulty paying attention, impulsive behaviors, and hyperactivity.

“Our findings clearly demonstrate that it is essential for clinicians to assess all children with ADHD for the presence of comorbid reading disability,” conclude the researchers, who were led by Kouichi Yoshimasu, MD, of the Mayo Clinic in Rochester, Minn.
