In the federal Multimodal Treatment Study, hundreds of kids with ADHD, whose families were desperate enough to enroll them in a randomized study, entered a well-funded and highly supervised National Institute for Mental Health program complete with specialized therapy, regular evaluation by developmental experts, and careful drug prescription—a setup that's about as realistic as a date on The Bachelor.

Within that very unusual, closely monitored environment, as reported in 1999, stimulant medications caused modest improvement after about a year. In response, use of these products surged nationwide, and Ritalin and its peers became household brands. But in March, the researchers described what happened after the lights went out. In their subsequent years in the real world, the drug-treated kids ultimately ended up no better off than the others.
