ADHD or attention deficit hyperactivity disorder has recently become more pronounced in the United States. In the past ADHD was under diagnosed as a learning disability. Children would be held back because it was assumed the child had issues learning. Now we understand that ADHD can cause problems with the student focusing on tasks. There are a number of symptoms of ADHD that can be seen. Those who have a mild case may seem more active than other children, but on the whole they are not affected.
Those with severe ADHD need medication to help calm them down. Psychologists have also worked with children suffering from the disorder to try to find a way of calming the person without using drugs that could affect the child.
