Hyperactivity and poor grades the result of genetics?

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?
