CHADD has local support groups in every state in the United States. Each group offers programming or information specific to their geographic area. CHADD (Children and Adults with Attention-Deficit/Hyperactivity Disorder) was founded in 1987 in response to the frustration and sense of isolation experienced by parents and their children with ADHD. At that time, one could turn to very few places for
support or information. Many clinicians and educators knew little about the disability, and individuals with ADHD were often mistakenly labeled "a behavior problem," "unmotivated," or "not intelligent enough." ADHD is medically and legally recognized as a treatable yet potentially serious disorder, affecting up to nine percent of all children, and approximately four percent of adults. Today, children with ADHD are eligible for special education services or accommodations within the regular classroom when needed, and adults with ADHD may be eligible for accommodations in the workplace under the Americans with Disabilities Act. CHADD is a success story, inspired by the desire of countless parents to see their children with ADHD succeed. From one parent support group in Florida, the organization grew dramatically to become the leading non-profit national organization for children and adults with ADHD. The Greater Orange County CHADD Chapter #455 serves all of Orange County, California and also welcomes people from surrounding communities.
