Is your child hyperactive? Millions of kids are, an the debate continues to rage on the role of genetics, environment and lifestyle as the cause (or a combination of all three).

Genetic causes are the reason behind school difficulties and hyperactivity, according to a new report. While this is not surprising, I doubt that genetics is the only reason for these things. What do you think?

I generally agree that genetics plays an important factor in why some kids find it hard to focus in school (not for lack of effort) and are labeled "hyperactive" -- but is that the end of the story?
