How does the ADHD brain work?
It seems that the brain of children and adults with ADHD hyperactivity disorder (ADHD) works somewhat differently from other people, and these differences in the brain of ADHD usually cause symptoms of disorder. Research continues, so new discoveries are often carried out on how the brain works and how ADHD is produced by the brain. In general, however, it has been observed that individuals with ADHD usually have an unusual amount of certain chemicals and neurotransmitters in the brain. The ADHD brain also seems to work differently in several key areas, all of which work on the production of different aspects of ADHD. For years, research has focused on the role of dopamine and related brain chemistry as contributing to the ADHD brain processes. Ritalin, one of the primary drugs that are often used to treat ADHD, usually change the way dopamine is produced and used in the brain. Newer research, however, has shown that many different areas of the brain seem to work on creating common ADHD symptoms.
Four main areas of potential ADHD brain activity are frontal lobe, cortex, limbic system and reticular activation system in the brain. For example, the frontal lobe is a place where a large part of neurotransmitters and neurological chemical research has been carried out. This is where the brain is produced and used by chemicals such as dopamine and glutamate. In the brain of ADHD, these chemicals seem to be produced either in excess or in insufficient quantities to function properly. These changes in the chemistry of the brain could cause effect, such as the inability to concentrate or correctly inhibit it.
Cortex of the brain is also strongly involved in the inhibition of brain activity. In the brain of ADHD, the bark does not prevent other brain areas right, leading to those who have ADHD, often have inappropriate explosions or speak without considering what to say. This can lead to disturbing behavior at the classroom or business meeting and other negative consequencesíchi.
These explosions can also be affected by the limbic brain system that controls emotions. The ADHD brain does not seem to be properly controlled by a limbic system, so individuals with ADHD may have wild mood swings or are unable to control emotional explosions. Because these different parts of the brain work, different symptoms of ADHD are due to a single system, but through combined efforts multiple parts of the brain.
The system of reticular activation in the ADHD brain also seems to be different from the "normal" brain. This part of the brain seems to control some focus and concentration of the frontal lobe as well as motor activity for a person. Unusual functions in this area may be responsible for one of the inability of a person with ADHD to focus on the task and for the tendency of those with ADHD to be hyperactive or it is difficult to sit at rest.
