CNN VAN - The number of children diagnosed with Attention Deficit Hyperactivity Disorder has significantly increased during the past 20 years.
A study released Friday found more than 10% of American kids were diagnosed with ADHD between 2015 and 2016. That was up from about six percent between 1997 and 1998. Minority groups saw the most pronounced increases.
The rate doubled in girls, although it is still much lower than in boys.
The U.S. has significantly more instances of ADHD than other developed countries.
Researchers found no evidence the condition is being overdiagnosed or misdiagnosed.
