Study pinpoints effects of different doses of an ADHD drug; finds higher doses may harm learning

New research with monkeys sheds light on how the drug methylphenidate may affect learning and memory in children with attention deficit hyperactivity disorder.
The results parallel a 1977 finding that a low dose of the drug boosted cognitive performance of children with ADHD, but a higher dose that reduced their hyperactivity also impaired their performance on a memory test.
“Many people were intrigued by that result, but their attempts to repeat the study did not yield clear-cut results,” says Luis Populin, an associate professor of neuroscience at the University of Wisconsin-MadisonSchool of Medicine and Public Health.
