The U.S. Senate passed S. Res. 370 in 2004, sponsored by Sen. Maria Cantwell, designating a single ADHD awareness day to combat stigma and improve access to mental health services. The ADHD Awareness Coalition (ADDA, CHADD, ACO) later expanded it to the full month of October.
October is National ADHD Awareness Month, and it's a great time to spread awareness about this disorder. First described in 1902 by British pediatrician Sir George Still, ADHD affects approximately 6.4 million children in the United States alone. While it can cause significant difficulty in school and social settings, with proper support and understanding from family, friends, teachers, and medical professionals, individuals with ADHD can lead healthy and successful lives. Let's use this month to learn more about the disorder and help create a more inclusive environment for those living with ADHD!

WHY THIS DAY MATTERS
During National ADHD Awareness Month, organizations and individuals come together offer support and guidance. They provide resources such as information on treatments, tips for managing the disorder, and mental health services so those affected by ADHD can get the help they need.
By raising awareness during ADHD Awareness Month, educators, medical professionals and members of the community become more knowledgeable about this disorder so they can better recognize early signs and symptoms. This can lead to earlier diagnosis which, in turn, can enable those affected to receive appropriate treatment sooner.
It's important for people to understand that ADHD is a real disorder that affects people in different ways. By promoting acceptance and understanding of the disorder during National ADHD Awareness Month, it can help to reduce the stigma associated with it and encourage those affected to seek help without fear of judgement or alienation.
