Why do One in Ten Kids in the U.S. Have ADHD?

A U.S. government survey claims that 1 in 10 U.S. children now has ADHD. This is a sizable increase from a few years earlier. ADHD (attention deficit hyperactivity disorder) makes it hard for children to pay attention and control impulsive behavior.

About two-thirds of the children diagnosed with ADHD are on medication.

According to Yahoo Finance:

“In the latest survey, 9.5 percent said a doctor or health care provider had told them their child had ADHD ... ADHD diagnosis is in many ways a matter of opinion. There's no blood test or brain-imaging exam for the condition. Sometimes reading disabilities or other problems in the classroom cause a teacher or others to mistakenly think a child has ADHD”.
