A recent Centers for Disease Control and Prevention (CDC) study examines survey data from the National Survey of Children’s Health to estimate the prevalence of ADHD diagnosis and treatment. The results indicate that, as of 2016, 6.1 million children aged 2-17 years living in the U.S. had been diagnosed with ADHD, which is similar to previous estimates. Almost two-thirds were taking medication, slightly less than half had received behavioral treatment in the past year, and nearly one fourth had received neither treatment.
