- <p>Scientists find a genetic cause for the distractive disorder
- </p>
- <p> Pay attention, parents. It is not your attitude but your
- genes that are to blame for the extreme restlessness and
- impulsiveness in your hyperactive child. According to research
- conducted at the National Institutes of Health, at least some
- cases of the behavioral disorder, thought to affect 3% to 5% of
- school-age children, are triggered by the same hereditary error
- that causes an uncommon endocrine disorder called generalized
- resistance to thyroid hormone. After studying 104 people from
- 18 families with a history of the rare disorder, scientists
- determined that 70% of affected children also suffered from
- hyperactivity. If confirmed, the results suggest that children
- who are diagnosed with hyperactivity, or attention-deficit
- disorder, as it is also known, should be examined for high
- levels of two different thyroid hormones. By treating the
- underlying biochemical abnormality in these cases, doctors may
- eventually be able to correct the behavioral problems.
