In the first known study of its kind, an article published in the August 1st issue of the journal SLEEP finds that children with attention deficit hyperactivity disorder (ADHD), and whose sleep efficiency is poor, experience significant improvement on some measures of the Continuous Performance Test (CPT) if they are treated with methylphenidate (MPH).
The study, conducted by Ridha Joober, MD, and Reut Gruber, PhD, of Douglas Mental Health University Institute and McGill University in Montreal, Canada, focused on 37 children between six and 12 years old with ADHD that was diagnosed based on criteria from the Diagnostic and Statistical Manual - 4th Edition. The subjects were divided into two groups based on the mean sleep efficiency score during the week of the placebo. Those above and below the mean were placed in the Poor Sleep Group and Good Sleep Group, respectively.
