From 1997 to 2016, the percentage of children in the U.S. with ADHD increased from 5.5 percent to 9.4 percent. ADHD is more common among boys than girls, with 13 percent of boys diagnosed compared to just 6.6 percent of girls. There are also slight differences in ADHD prevalence by ethnicity. As of 2018, 13 percent of African American children had been diagnosed with ADHD, compared to 9.6 percent of white children and only 7 percent of Hispanic or Latino children.
ADHD is most commonly treated with medication, therapy, or a combination of both. A couple of the most well-known medications to treat ADHD include Ritalin and Adderall. Both drugs are known for their potential for abuse among those not suffering from ADHD, yet the overall use of both Ritalin and Adderall among high school students has declined in recent years. Therapy can be effective in treating and coping with ADHD, especially considering that many of those who suffer from the disorder also suffer from another disorder. For example, it is estimated that around 33 percent of children in the U.S. with ADHD also suffer from anxiety and 17 percent suffer from depression. Similarly, around 20 percent of university students with ADHD frequently felt depressed as of 2016.
