Kentucky leads nation in percentage of children who have been diagnosed with attention deficit hyperactive disorder

Kentucky leads the nation in the percentage of children who have been diagnosed with attention deficit hyperactive disorder, according to the latest available data, which "showed that ADHD levels have risen steeply in the past decade across the nation," Laura Ungar reports for The Courier-Journal.

Ungar writes that "19 percent of Kentucky children ages 4-17 have been diagnosed with ADHD at some point, compared with 11 percent nationally and 16 percent in Indiana." Almost 15 percent of Kentucky children had the diagnosis in 2011, based on polling by the U.S. Centers for Disease Control and Prevention.

"We're probably over-diagnosing it to a certain extent," Dr. Christopher Peters, a psychiatrist and assistant professor of pediatrics at the University of Louisville, told Ungar. "But these numbers indicate a problem. There are many kids in need."

The high numbers could "reflect the state's rampant poverty, since ADHD is identified more frequently in the poor," Ungar writes. "Others say more children here may be genetically prone to the disorder or face other risk factors. . . . Studies show that at least a third of parents who had ADHD as children have kids with the diagnosis."

Any over-diagnosis may stem from "overworked primary care doctors who aren't experts in the disorder" and may be over-diagnosing ? and possibly over-prescribing ? both locally and nationwide," Ungar writes. "Roughly 8 percent of of school-aged boys nationally and nearly 4 percent of girls took ADHD medications in 2012, according to data from the pharmacy benefit management firm Express Scripts."

There are "financial incentives" for an ADHD diagnosis, Ungar notes. "A diagnosis may translate into disability payments if a child has measurable and serious problems, and students with ADHD can get extra help in school. . . . Experts say the higher numbers may also indicate greater awareness of the disorder, meaning the truly needy are getting the medication, therapy and support they deserve."

However, Dr. Carmel Wallace, pediatrics chairman at the University of Kentucky, "said parents rarely push for a diagnosis to get a disability check," Ungar reports. "And the threshold for disability is high."

Still Kentucky has high rates of children and adults getting Social Security disability payments, and ranks high in some risk factors for ADHD.

"Scientists also have linked ADHD to alcohol and tobacco use during pregnancy ? although doctors said it's unclear whether smoking is a cause or simply occurs more often in families with afflicted children," Ungar reports. "Kentuckians smoke at the nation's highest rate and also have high rates of substance abuse overall."

Ungar's example of an ADHD child was, in preschool, "a tiny tempest ? at times defiant, other times bouncing distractedly from toy to toy at daycare, while other children were absorbed in play," but as a second-grader "is doing well . . . with a mild stimulant and counseling."
