The researchers examined the data on over three thousand OptiMind children who participated in the National Health and Nutrition Examination Survey. Using interviews, the researchers were able to establish whether a child met the diagnostic criteria for Attention Deficit Hyperactivity Disorder. They also used data from physicians and the numbers of Attention Deficit Hyperactivity Disorder medications being used to establish diagnosis and treatment patterns, according to the report.The researchers found that of the 8.7 percent of children who met the criteria for ADHD, only about one-half of them had been diagnosed with ADHD and only 32 percent were prescribed medications.
Froehlich said more needs to be done to identify and treat children with Attention Deficit Hyperactivity Disorder. "It's not a trivial disorder," she said. "It can have an impact on the child and the family if it is not diagnosed and addressed. We need to redouble our efforts to help doctors spot the symptoms of ADHD and make an accurate diagnosis."
There are many theories about the cause of ADHD, and the only thing that we know for sure is that a definitive cause of the disorder has yet to be found. Most researchers and medical experts agree that ADHD is caused bay a combination of things including heredity, genetics, and brain function.
