The History of ADHD:
Kids who were unable to control their actions were once thought of as having behavior issues or a lack of disciple or respect for elders before the discovery of ADHD. Although the disorder was first mentioned in 1902 by British pediatrician Sir George Still, the American Psychiatric Association did not recognize ADHD as a mental disorder until the late 1960s.
In 1980, the APA 
changed the name of the disorder from hyperkinetic impulse disorder to attention deficit disorder. Since ADHD was accepted as a real disorder, professionals such as teachers and doctors now are able to recognize applicable behavior issues for what they are, symptoms of ADHD.

Causes of ADHD:
Although one specific cause of ADHD has not been discovered, through various studies, scientists have discovered some possible causes. It seems that genes play a large role. In addition, illnesses also seem to have an effect.
However, scientists feel that in most cases, the development of ADHD is due to a combination of factors. These could even include a patient's social environment, brain injuries and their nutritional habits.
