ADHD Statistics

ADHD STATS

 

   Attention deficit hyperactivity disorder (ADHD) is the most common pediatric neurodevelopmental disorder in North America

   Boys are more than twice as likely as girls to have ADHD

   Children with ADHD have 3 times as many peer problems and are 10 times as likely to have friendship problems

   Rates of ADHD diagnosis increased an average of 3% per year from 1997 to 2006 and an average of approximately 5% per year from 2003 to 2011

   The average age of ADHD diagnosis is 7 years of age

   Children with ADHD have a higher rate of non-fatal injuries (4.5% vs. 2.5% controls)

   Data suggests that prenatal tobacco exposure accounts for 270,000 excess cases of ADHD, and lead exposure accounts for 290,000 cases of ADHD in U.S. children.

   Blood lead levels over 3.5ug/dl doubles the risk for developing ADHD

   In 1997 DTCA (direct to consumer advertising) guidelines were changed to allow marketing of controlled substances directly to the US consumer

   The Journal of American Academy of Child & Adolescent Psychiatry contained zero ads for ADHD meds from1990 to 1993, and approximately 100 pages of ADHD ads per year in 2003

   The FDA has cited every major ADHD drug, including the stimulants Adderall, Concerta, Focalin and Vyvanse, for false &

   misleading advertising since 2000, some of them multiple times

   Psychostimulants, particularly amphetamines, may cause central nervous system damage, heart damage (cardiomyopathy in 87% of chronic methamphetamine users), chromosomal damage (200-300% increase) and sudden cardiac death (in children with underlying heart defects)

   Studies show the benefits of ADHD stimulant medication seen at 14 and 24 months, were no longer present at 36 months

   A study of ADHD stimulants demonstrated that children who were no longer taking ADHD medication at the 8 year follow-up were generally functioning as well as children who were still medicated

   2.7 million US children with ADHD ages 4 – 17 years receive medications for the disorder

   Boys are 2.8 times more likely to take medication than girls for ADHD

   Stimulants are ineffective in 70% of ADHD children who also have anxiety

   A study of more than 900,000 Canadian children found that boys born in the month of December were 30% more likely to be diagnosed with ADHD than boys in their grade who were born the previous January

   Girls born in December were 70% more likely to be diagnosed with ADHD than girls in their grade born the previous January

   Iron storage levels (ferritin) were abnormally low in 84% of children with ADHD compared to 18% of controls

   Low ferritin levels are correlated with more severe ADHD symptoms

   Carnitine treatment has been shown to decrease attention problems and aggressive behavior in boys with ADHD by 20-65%

   Phosphatidylserine supplementation helped with attention and learning in approximately 90% of ADHD children studied

   Magnesium deficiency was found in 95% of children with ADHD

   ADHD children given 6 months of magnesium supplementation showed a significant decrease of hyperactivity

   55% children with ASD and 67% children with ADHD exhibited neurobehavioral regression when given a nasal pollen challenge (allergy provocation test)

   Up to 50% of children with hyperactivity are sensitive to artificial food colors, flavorings, preservatives, and salicylates
