A steady rise in attention-deficit/hyperactive disorder (ADHD) has begun to slow, but the heightened numbers are still cause for some concern.

According to HealthDay News, a new government survey asked 95,000 parents if they had children aged 4 to 17 diagnosed with ADHD. 11 percent - just more than one in ten - had been diagnosed. The previous figure for that survey came in 2007 and it was 9.5 percent at that time.

The report comes from the Centers for Disease Control and Prevention (CDC) and it found about one in every five high school boys and one in every eleven high school girls were diagnosed with ADHD.

Consequently, ADHD prescriptions have increased by about one million from 2003-2004 to 2011-2012. About 3.5 million children aged 4 to 17 are being prescribed drugs such as Ritalin and Concerta.

"This finding suggests that there are a large number of young children who could benefit from the early initiation of behavioral therapy, which is recommended as the first-line treatment for preschool children with ADHD," study author and CDC researcher Susanna Visser said in a journal news release.

The researchers' work was published Friday in the Journal of the American Academy of Child and Adolescent Psychiatry. The survey found half of children who are diagnosed with ADHD receive that diagnosis by the age of six.

"This finding raises concerns about whether these children and their families are receiving needed services," Dr. Michael Lu, senior administrator at the U.S. Health Resources and Service Administration (HRSA), said in the journal news release.

The survey also found children with ADHD are not always getting proper treatment, which is not drugs alone. In 2011-2012, 18 percent of children with ADHD did not receive psychiatric counseling or proper drug treatment.

Visser also acknowledged a common problem with ADHD diagnoses: that sometimes hyperactivity and short attention spans are just signs of kids being kids.

"A lot of symptoms of ADHD, like hyperactivity, can also be appropriate developmental markers of age," she told CNN. "You have to see a more 'wait and see' approach. Can they better be attributed to other things: sleep, divorce, trauma? A lot of things can look like ADHD, and once those symptoms aren't appropriate for a child's age, then we need to get treatment."
