What ADHD Awareness Month is
ADHD Awareness Month is a US observance held every October, built around public education about Attention-Deficit/Hyperactivity Disorder: how it is diagnosed, how it is treated, and how often it goes undiagnosed, especially in adults. The Centers for Disease Control and Prevention's data page puts current ADHD diagnoses at roughly 7 million US children and adolescents ages 3 to 17, about 11.7 percent, based on the 2024 National Survey of Children’s Health administered by HRSA and reported by CDC; an earlier CDC-cited 2022 survey had put the ever-diagnosed figure at 11.4 percent, about 7.1 million, with 10.5 percent, about 6.5 million, carrying a current diagnosis at that time.
The observance is not a federal public holiday and does not itself require a closure or paid leave. October schedules can still be affected by other holidays and employers’ policies. It is organized, every year, by a coalition of three advocacy groups: the Attention Deficit Disorder Association (ADDA), CHADD, and the ADHD Coaches Organization (ACO), which jointly run webinars, public-education toolkits, and community events under the shared campaign site ADHDAwarenessMonth.org.
Five checked September dates and their resolutions
Congress did not approve a single ADHD awareness day and stop there. It approved one every year for five years straight. Senator Maria Cantwell of Washington sponsored all five, always in the Senate, always as a simple resolution that passed after introduction and, in the 2004 case, committee consideration, by unanimous consent or without objection: Senate Resolution 370 in 2004 (with Senator Richard Durbin, designating September 7), Senate Resolution 201 in 2005 (again with Durbin, designating September 14), Senate Resolution 544 in 2006 (designating September 20), Senate Resolution 295 in 2007 (Cantwell alone, designating September 19), and Senate Resolution 649 in 2008 (with Senator Gordon Smith of Oregon, designating September 18).
Each resolution named a single calendar date for that year only. None of the five ever states a recurring rule, an annual formula, or a month. Read together, they show the Senate doing the same specific thing five years in a row without setting up a standing designation once and letting it run on its own; each of these documents named its particular year’s date, rather than providing a recurring formula. After 2008, this calendar could not find a sixth.
What the checked resolutions establish, and the current campaign
This calendar searched Congress's bill database for any later resolution using the same title, and for the shorter "ADHD Awareness" phrasing that later replaced "Attention Deficit Disorder" in common usage, and found nothing after Senate Resolution 649 in 2008: no sixth matching Senate resolution, House companion or October proclamation among the documents examined. These search results do not establish that subsequent proposals ceased, nor a reason for any apparent gap.
ADDA, CHADD and ACO jointly run the present month-wide campaign. ADDA, CHADD, and the ADHD Coaches Organization, the same groups behind the Senate resolutions, continued the campaign on their own authority, past the single September date Congress had last approved in 2008, into what is now a full month observed every October. The Centers for Disease Control and Prevention hosts its own ADHD Awareness partner toolkit each October, with shareable social media content and links to educational material; that documents collaborative, informational involvement by a federal agency. The toolkit itself is not a proclamation or statute, and neither instrument was identified for the October campaign in the records consulted.
A secondary source that's partly right, for the wrong reason
One account of this history, published on the blog ImpactADHD.com, describes the origin as declaring "the 3rd Wednesday of September" to be National ADHD Awareness Day. Checked against the actual dates the Senate designated, that description is a coincidence, not a rule. September 20, 2006 and September 19, 2007 genuinely were the third Wednesday of their respective months, so for those two years the blog's shorthand happens to land on the right date. But September 7, 2004 was a Tuesday, September 14, 2005 was the second Wednesday of that September, and September 18, 2008 was a Thursday. None of the five resolutions themselves state a weekday-based formula; each designates one specific date, decided fresh by the Senate that year.
The gap between the primary text and the paraphrase is a useful reminder for a reader trying to plan around any of these observances: a summary that gets two years right out of five can still be describing something that never existed as a rule. What existed was five separate acts of Congress, not one recurring one.
Where this sits next to its fall neighbors
This calendar has now checked the federal paper trail behind several October and November health observances, and their instruments and designated dates differ. American Diabetes Month has an actual presidential proclamation on record, Reagan's Proclamation 4994 in 1982, renewed by name again in 1985. National Epilepsy Awareness Month has a different record: three cited proposals remained in committee, but S.Con.Res.48 passed both chambers in 2003 without becoming a statute. Domestic Violence Awareness Month has its own dated instruments: Congress designated it by name for one specific year, 1989, in a joint resolution, and went back and renewed that same one-year designation once more for 1991, with no subsequent comparable law identified in that guide’s checked records; its later cited presidential documents recognize the month without naming a fresh designation law.
ADHD Awareness Month fits none of those three patterns. Its five cited Senate resolutions passed in consecutive years. Epilepsy’s history also includes a passed 2003 concurrent resolution, so the contrast is between the instruments and their date wording, rather than success versus complete failure. The cited ADHD measures designate particular dates. The Diabetes and Domestic Violence guides also distinguish year-specific recognition from recurring statutory rules; the consulted ADHD records yielded no later measure matching this five-year series. The checked five-year series provides evidence of Senate recognition on those dates, without establishing an abrupt end to all later federal activity. It's one of ten October observances that claim the whole month rather than a single day, a group this site's National Days in October page lists with their documented origins, from National Disability Employment Awareness Month's 1945 act of Congress down to LGBTQ+ History Month's single-teacher 1994 initiative.
