Three nonprofit organizations will recognize ADHD awareness month this October with a video contest to raise awareness about ADHD. The video contest centers around the theme “Knowing is Better: ADHD through the lifespan.” The three nonprofits are collectively known as the ADHD Awareness Month Coalition. The nonprofits in the coalition are Children and Adults with Attention-Deficit/Hyperactivity Disorder (CHADD) the Attention Deficit Disorder Association (ADDA) and the ADHD Coaches Organization (ACO)."
