On the Rocafort family’s kitchen shelf in Ball Ground, Ga., next to the peanut butter and chicken broth, sits a wire basket brimming with bottles of the children’s medications, prescribed by Dr. Anderson: Adderall for Alexis, 12; and Ethan, 9; Risperdal (an antipsychotic for mood stabilization) for Quintn and Perry, both 11; and Clonidine (a sleep aid to counteract the other medications) for all four, taken nightly.

Quintn began taking Adderall for A.D.H.D. about five years ago, when his disruptive school behavior led to calls home and in-school suspensions. He immediately settled down and became a more earnest, attentive student — a little bit more like Perry, who also took Adderall for his A.D.H.D.

When puberty’s chemical maelstrom began at about 10, though, Quintn got into fights at school because, he said, other children were insulting his mother. The problem was, they were not; Quintn was seeing people and hearing voices that were not there, a rare but recognized side effect of Adderall. After Quintn admitted to being suicidal, Dr. Anderson prescribed a week in a local psychiatric hospital, and a switch to Risperdal.

While telling this story, the Rocaforts called Quintn into the kitchen and asked him to describe why he had been given Adderall.

“To help me focus on my school work, my homework, listening to Mom and Dad, and not doing what I used to do to my teachers, to make them mad,” he said. He described the week in the hospital and the effects of Risperdal: “If I don’t take my medicine I’d be having attitudes. I’d be disrespecting my parents. I wouldn’t be like this.”

Despite Quintn’s experience with Adderall, the Rocaforts decided to use it with their 12-year-old daughter, Alexis, and 9-year-old son, Ethan. These children don’t have A.D.H.D., their parents said. The Adderall is merely to help their grades, and because Alexis was, in her father’s words, “a little blah.”
