Are ADHD Medications Overprescribed?

The Wall Street Journal:

In recent years, the number of children in the U.S. being treated with prescription medication for attention deficit hyperactivity disorder has grown dramatically.
That trend has led to concern among some doctors, parents and child advocates that many children are taking ADHD medication unnecessarily.
These critics suggest that in many cases ADHD is a mistaken diagnosis for children who are simply immature or undisciplined. And even when the diagnosis is correct, they say, many children who are taking medication for ADHD could do as well or better with alternative treatments, including dietary and behavioral therapies, that have fewer side effects.
