Ritalin: Studies

What further confounds the culture-of-Ritalin school is that A.D.H.D. turns out to have a considerable genetic component. As a result of numerous studies of twins conducted around the world over the past decade, scientists now estimate that A.D.H.D. is about seventy per cent heritable. This puts it up there with the most genetically influenced of traits--traits such as blood pressure, height, and weight. Meanwhile, the remaining thirty per cent--the environmental contribution to the disorder--seems to fall under what behavioral geneticists call "non-shared environment," meaning that it is likely to be attributable to such factors as fetal environment or illness and injury rather than factors that siblings share, such as parenting styles or socioeconomic class.

In the largest clinical study of its kind, researchers concluded that Ritalin can help 82 to 85 percent of the children who receive the drug. But other studies have raised questions about its long-term impact on substance abuse.
