It is not possible to tell whether this increase represented a change in the number of children who have ADHD or a change in the number of children who were diagnosed.Percent of children with a parent-reported ADHD diagnosisSkip Over Chart Container67891011Percent (%)19971999200120032005200720092011201320152017681012Percent (%)19971999200120032005200720092011201320152017NSCH (4-17 yr)Redesigned NSCH (2-17 yr)NHIS pub.

[Data for 1997-2012] [Data for 2013-2016]• NHIS publications: Estimates aggregate 3 years of data and include children 5-17 years of age until 2012, now 3-17 years of age. [Data for 1998-2009] [Data for 2011-2013] [Data for 2015-2018]• NSCH:National Survey of Children's Health; telephone survey data; estimates include children 4-17 years of age.• "Redesigned" NSCH (as of 2016): Now an online and mail survey; estimate includes children 2-17 years of age. Because the 2016 NSCH survey used different methods, the estimate is not directly comparable with estimates based on previous NSCH data.Note: Age ranges for published data vary. In previous decades, the focus of information collected on ADHD generally was on school age children; this has been expanded to include preschool ages as young as 2 years of age. Because the number of children with ADHD increases with age, estimates that include younger children are likely to be somewhat lower than those that focus on older children.History of ADHDEstimates for the percent of children in the population who have ADHD vary widely across time and across survey methods. A historical view can provide necessary context to understand changes in the epidemiologyA of ADHD. The way that ADHD is diagnosed has changed over time, so the difference in these numbers is likely to be influenced by variations in how the diagnostic criteria were applied.In addition, there were differences in the demographic characteristics of the samples used to calculate the estimates. It is also possible that the samples were exposed to factors that affect ADHD, but until more is known about these factors, it is not possible to know whether changes in these factors explain some of the variation. Perhaps relatedly, the number of FDA-approved ADHD medications increased noticeably since the 1990s, after the introduction of long-acting formulations.Historical timeline of ADHDThe historical timeline below shows* Estimates from studies across the years (until 2013) for the percent of U.S. children with ADHD.* How the criteria used to diagnose the condition have changed over time.* The approval of medication treatments by the Food and Drug Administration (FDA) beginning with Benzedrine in 1936.Timeline of ADHD diagnostic criteria, prevalence, and treatmentView and print larger version of timelineView LargerDownloadTimeline of ADHD diagnostic criteria, prevalence, and treatment throughout the years.On This Page* ADHD diagnosis throughout the years* History of ADHD* Historical timeline of ADHDRelated PagesView All< Hyperactivity Disorder (ADHD)Back to Top* Data and Statistics on ADHD* State Profiles — Diagnosis and Medication Treatment* State-based Diagnosis and Treatment Data* ADHD Information and Resources for States* TreatmentView All Attention-Deficit / Hyperactivity Disorder (ADHD)State Profiles — Diagnosis and Medication TreatmentOctober 23, 2024Sources Print ShareFacebook LinkedIn Twitter SyndicateContent Source:National Center on Birth Defects and Developmental DisabilitiesFootnotes1.
