CLEVELAND, Ohio - The findings from a new study done in Iceland are published in the journal "Pediatrics."
Researchers studied the effects of ADHD medications on nearly 12,000 children taking standardized tests in the fourth and seventh grades.
"Medicines not only reduce symptoms of ADHD, something we've known for a long, long time, since 1937," said Dr. Mike Manos with the Cleveland Clinic Children's Hospital. "They also make a difference in functional daily living, in academic learning, and that's something that many people have questioned over the years."
Results show students with ADHD, who started taking the medications within a year of their tests, had smaller declines on their test scores.
