Your children have Attention Deficit Hyperactivity Disorder (ADHD)? In the long-term they will be no better off using dangerous drugs like Ritalin or Concerta than behavioral therapies according to a study of 600 ADHD sufferers in the UK.
ADHD medications are widely prescribed in Australia - for some reason rates of prescription are 5X the average in WA. I agree with Dr. Aitkins - parents whose children have ADHD should monitor their sugar consumption.
Update: This report from today's New York Times suggests that kids with ADHD and other behavioral disorders suffer a lag in their development not a permanent impairment. Give them help but, most of all, give them time.
