adhd
"My daughter was diagnosed with ADHD in May 2009 on her 8th birthday.  She was put on Concerta and we immediately noticed a difference.  We have had to increase it a couple of times but there has never been a negative side effect. She even noticed the difference in her ability to focus at school and at home.  It has also helped her to maintain her friendships (she not as annoying). I am satisfied with how Concerta has helped my daughter."
