O.K. I've heard it a hundred times from my prison guard friends， 'I don't beli they read an article in a magazine， or saw a show on TV once. I guess they also believe in aliens in government， and that Elvis still lives somewhere in Oklahoma.
Look， there are lots of physical differences between the actual brains of people with ADD and those who don't have it， and there are also functional differences in the way that their brains work. And there are lots of scientists and physicians who are investin their research is too boring to make the Morning Show on TV doesn't mean that it doesn't exist， or isn't true.
The Functional Differences include studies with EEGs， Q-EEGs， CPTs， psychological testing， and 'functional' MRIs areas of the brain， differences in brainwave patterns， and differences in glucose metabolism between ADHD subjects and non-ADHD subjects. They also showed the ADD ADHD groups to have poorer performance on timed tasks， slower reaction time， slower processing times， lower problem solving abilities， less fine motor control， less gross motor control， differences in evoked potentials， and problems with inhibition， to the controls.
The Structural Differences include studies with MRIs， PET scans， and SPECT scans. They show subtle structural differences in the prefrontal cortex ， ， They also show that the right hemisphere of the ADHD brain is， on average， 5% smaller than the control groups. They also show differences in blood flow in certain parts of the brain， as well as specific chemical abnormalities in ADHD subjects.
The studies on Essential Fatty Acid levels in ADHD subjects vs. non-ADHD subjects are interesting. The ADHD groups had significantly lower concentrations of key essential fatty acids than did the control groups， and about 40% of the ADHD group showed signs of EFA deficiency . Low levels of Omega 6 EFAs contributed to higher incidents of illness ， and deficits in Omega 3 EFAs contributed to problems with learning， behavior， sleep， and temper. These studies support the case for EFA supplementation as a part of the overall treatment approach to ADHD.
Studies on Attention Deficit Disorder show gene alterations that may contribute to ADHD in some children. They are especially looking at the DRD4 dopamine receptor gene. Familial Studies show that Attention Deficit Disorder runs in families. For example， a child with an older sibling with ADHD is 300% to 500% more likely to himself have Attention Deficit Disorder than is a child without ADHD siblings. Twin studies and Adoption studies are also included.
Is your head spinning yet? I hope so.
