Most psychologists and medical specialists agree that true ADHD, as opposed to “mere” intermittent distractibility or high activity, reflects a problem in how the nervous system functions, but they do not know the exact nature or causes of the problem (Rutter, 2004, 2005). Research shows that ADHD tends to run in families, with children”especially boys”of parents who had ADHD somewhat more likely than usual to experience the condition themselves. The association does not necessarily mean, though, that ADHD is inborn or genetic. Why? It is because it is possible that parents who formerly had ADHD may raise their children more strictly in an effort to prevent their own condition in their children; yet their strictness, ironically, may trigger a bit more tendency, rather than less, toward the restless distractibility characteristic of ADHD. On the other hand (or is it “on the third hand"?), the parents' strictness may also be a result, as well as a cause of, a child's restlessness. The bottom line for teachers: sorting out causes from effects is confusing, if not impossible, and in any case may not help much to determine actual teaching strategies to help the students learn more effectively.
