Scattered: How Attention Deficit Disorder Originates and What You Can Do About It

by Gabor Maté

True or not, narrow genetic explanations for ADD and every other condition of the mind do have their attractions. They are easy to grasp, socially conservative and psychologically soothing. They raise no uncomfortable questions about how a society and culture might erode the health of its members, or about how life in a family may have affected a person’s physiology or emotional makeup. As I have personally experienced, feelings of guilt are almost inevitable for the parents of a troubled child. They are all too frequently reinforced by the uninformed judgments of friends, neighbors, teachers or even total strangers on the bus or in the supermarket. Parental guilt, even if misplaced, is a wound for which the genetic hypothesis offers a balm. There is a significant hereditary contribution to ADD—sensitivity, subject of the next chapter—but I do not believe any genetic factor is decisive in the emergence of ADD traits in any child.1 Genes are codes for the synthesis of the proteins that give a particular cell its characteristic structure and function. They are, as it were, alive and dynamic architectural and mechanical plans. Whether the plan becomes realized depends on far more than the gene itself. It is determined, for the most part, by the environment. To put it differently, genes carry potentials inherent in the cells of a given organism. Which of multiple potentials become expressed biologically is a question of life circumstances.
