The Washington Post (1/6, Johnson) reports a new study shows that “the stimulants Ritalin and Adderall…don’t act on the brain’s attention circuitry as had long been assumed.” Rather, the ADHD medications “primarily target the brain’s reward and wakefulness centers.” The research team “compared images of children who took prescription stimulants on the day of their scan with those of children who did not take stimulants. By studying the connections that allow different regions of the brain to communicate with one another, the scientists discovered that stimulants were promoting increased activity in the wakefulness and reward regions, but not in the attention ones.” The study “supports an increasing body of research that has pointed toward lack of proper sleep as a contributor to ADHD.” The study was published in Cell.
