ADHD is a heritable neurodevelopmental disorder for which treatment generally consists of medication for children as well as behavior therapy. Recently, new nonpharmacologic options have become available, including digital therapeutic devices for ADHD. The pace at which these technologies are emerging makes it challenging for clinicians to remain abreast of the latest developments. This study examined whether online continuing medical education (CME) could improve the knowledge and confidence of physicians regarding the evidence for nonpharmacologic therapeutics in the management of ADHD.
