ADHD diagnoses surge overseas

Attention Deficit Hyperactivity Disorder (ADHD) diagnoses are surging overseas, as well as in the U.S. Children may be taking powerful drugs needlessly, warn researchers in the British Medical Journal (BMJ).

In Australia, prescriptions for the stimulant Ritalin and other ADHD drugs rose by 72 percent between 2000 and 2011, while in Britain and the Netherlands prescriptions roughly doubled between 2003 and 2008, said the paper.

According to the US National Institute of Mental Health (NIMH), nearly one in 11 American children aged 13-18 and one in 25 adults are affected by ADHD.

Ritalin and other drugs are appropriate only for “severe” ADHD symptoms, which occur among about 14 percent of children with the condition, the study noted. Yet 87 percent of U.S. children diagnosed with ADHD in 2010 received medications.
