ADHD Statistics

 

  • ADHD affects 2-5% of all children.
  • ADHD was first described about 100 years ago but is no more prevalent now, just better recognized.
  • Although up to 3x as many boys are diagnosed with ADHD as girls, it is now suspected the incidence is more like 1:1.
  •  Research suggests 50-80% of children with ADHD will continue to meet diagnostic criteria in adolescence and 50-70% will have symptoms causing impairment as adults.
  • The incidence of ADHD is approximately the same across all countries and races.
  • Most ADHD children have the social and emotional maturity of a child two thirds their age.
  • The stimulants Ritalin and Dexamphetamine have been used for over 40 years.  Between 80-90% of children with significant ADHD will be helped in the short term by one of the stimulants.
  • Approximately half of the children who present with ADHD are also troubled by specific learning disabilities, eg dyslexia.
  • Oppositional Defiant Disorder is a co-morbid condition found in 40-60% of children with ADHD.
