There is still a search for the cause of this disorder, but over the years imaging studies have shown that the brain regions might have a malfunction in the patients that have ADHD, therefore is causes them to have the symptoms of the condition.
These images show that the brain areas that are reduced in size in children with ADHD are the ones that control attention. Many studies say that mutations in several genes might play a role in this disorder. Non-genetic stipulations that have to do with the developing of this disorder are premature birth, maternal alcohol and tobacco use. These stipulations can cause a child to develop ADHD.
When children grow up they absorb mental activities that are called executive functions, these functions help them divert distractions and remember things. If a person cannot inhibit interfering thoughts and impulses the executive functions will not be able to be carried out. These executive functions are accomplished early in childhood. An example is when children talk to themselves to try to remember something. Once...
