- ADHD, its diagnosis, and its treatment have been controversial since the 1970s.
- Despite being the most commonly studied and diagnosed psychiatric disorder in children and adolescents, the cause in the majority of cases is unknown.
- ADHD is diagnosed approximately three times more in boys than in girls.
- The United States uses ADHD diagnoses criteria different from the diagnoses criteria used in Europe. The United States diagnoses ADHD 20 times more often with this criteria than in France.
- The Drug Enforcement Agency has classified ADHD drugs Ritalin, Adderall and Dexedrine as Schedule II Stimulants. This is the same drug classification as Cocaine.
- Sales of stimulant medication for ADHD in 2012 reached nearly $9 billion, more than five times the $1.7 billion a decade earlier.
- The number of children on medication for ADHD had soared from 600,000 in 1990 to 3.5 million in 2012.
- There has been a 42% increase in the number of reported cases of ADHD since 2003.
- In 2010 there were 31,244 Emergency Room visits related to persons taking ADHD medications, most of the cases were a result of overdose or acute side effects which can include mania and hallucinations.
- Based on the presenting symptom ADHD can be divided into three subtypes: predominantly inattentive, predominantly hyperactive-impulsive, and combined type.
- As ADHD is common, natural selection likely favored these traits, at least individually, and they may have provided a survival advantage. Genetic research supports this theory.
- Children exposed to lead, even low levels, or may develop problems which resemble ADHD and fulfill the diagnosis.
- There are children who may react negatively to synthetic food dyes or preservatives.
- The diagnosis of ADHD can represent family dysfunction or a poor educational system rather than an individual problem.
- Current models of ADHD suggest that it is associated with functional impairments in some of the brain's neurotransmitter systems, particularly those involving dopamine and and norepinephrine.
