The sooner children diagnosed with attention-deficit/hyperactivity disorder start taking medications, the better their math scores may be.
Researchers at the University of Iceland studied the effects of ADHD medications on nearly 12,000 children. They took standardized tests in the 4th and 7th grades.
Results show students with ADHD, who started taking the medications within a year of their 4th grade tests, had much smaller declines on their test scores from the 4th to the 7th grade- especially in math.
But kids with ADHD who did not receive medications saw their test scores decline significantly between the 4th and 7th grades.
Researchers say starting medications as early as possible may help children with ADHD progress more consistently in the classroom.
Many doctors agree.
"Medicines not only reduce symptoms of ADHD, something we've known for a long, long time, since 1937. They also make a difference in functional daily living, in academic learning, and that's something that many people have questioned over the years," said Mike Manos, Ph.D. of Cleveland Clinic.
Complete findings for this study are in the journal "Pediatrics."
