The singer has released several PSAs about embracing his struggles with the disorder, and wants others affected to do the same.
Now, with the help of the company Shire, Adam is starting a contest for adults with ADHD to tell their stories. Those with the most compelling submissions will win prizes as well as the opportunity to be a spokesperson for the project.
"'The Own It Project' is important because it encourages adults, like me, who are owning their ADHD, to become advocates and tell their story," Adam said. "I hope that this effort will help people realize the importance of owning their ADHD."
