Critics of Ritalin claim that is overprescribed. However, that is debatable. The Journal of the American Medical Association published a study in 1998 that found no evidence of widespread overprescription of Ritalin.
But other authorities, including the Drug Enforcement Administration, have found some worrying trends. A study released in 2007 found that children were twice as likely to be on Ritalin if their parents were divorced. Worldwide, ADHD prescriptions has increased 300 percent since 1993, and in 2008, an Australian doctor asserted that 30 percent of ADHD cases in Australia are improperly diagnosed and that even in legitimate cases of ADHD, medication frequently is not required.
