An estimated 7 million children in the U.S. ( 11.4% of all children) have been diagnosed with ADHD.
The prevalence of ADHD in children varies between 5% and 10% depending on the region of the world.
There are medical, social/cultural and educational explanations as to why ADHD is more common in the United States .
Hyperkinetic Impulse Disorder, coined in 1957 , was depicted as common, occurring in most classrooms.
Environmental factors thought to contribute to ADHD behaviors, ranging from synthetic food additives and exposure to atmospheric lead, to lack of exercise and time in nature.
Treatment guidelines are different across countries.
Why some people have high levels of ADHD but most do not is related far more to genetic differences across individuals than to differences in family interactions or contexts.
Even if one has the genetic predisposition, how one is parented and schooled can go a long way toward exacerbating or minimizing impact via building of strengths.
