Brain scan- At A Look

Imaging the ADHD brain makes it possible for photographs of the brain to be taken and this enables neurologists and neuroscientists to see how the brain functions. Among the various types of brain imaging methods are CT scans (computerized tomography), MRI scans (magnetic resonance imaging), PET scans (positron emission tomography), and fMRI (functional magnetic resonance imaging). A great many studies have been done making use of these aforementioned techniques when it comes to understand and learn about the brains of children who have been diagnosed with ADD/ADHD.Checkout brain scans for more info.

Having used the methods that we have already mentioned researchers have discovered that there are noticeable differences between the brains of children with ADHD and those of children who do not have ADHD. Most of the scans or imaging studies up to now have been done using CT and MRI scans but this is a static way of observing the brain. By using these and other methods researchers can now indicate that the region of the brain that is called the frontal cortex is actually involved when it comes to the brains of children with ADHD. This part of the brain is actually a part of the cerebral cortex otherwise known as the outer surface of the brain. This area is divided into the temporal lobe, the occipital lobe, the parietal lobe and the frontal lobe. The frontal lobe is mostly involved with functions like problem solving, attention, reasoning, and so on.

Evidence would suggest that the ADHD brain shows a smaller right frontal lobe than the brain of a child who does not have ADHD. People who suffer with damage to the frontal lobe because of illness or an accident tend to exhibit many similar symptoms to those associated with ADHD. Thankfully technology has advanced and now researchers are able to look at the brain with other methods aside from the static images provided by CT and MRI scans.
