FLATOW: How - you have found that there are different rewards or reward pathways in the brain for people with ADHD and people without it.
Dr. VOLKOW: No. The reward pathway is the same. What we were actually investigating was whether there were changes in the function of the dopamine reward pathway in the brain in individuals who suffer from attention deficit hyper activity disorder.
So, they still use imaging specifically to monitor different markers of the dopamine system in the brain of individuals with ADHD. We studied 55 of those individuals and 43 healthy controls and then compare the brain of these two groups of subjects. And found that indeed as what have been suggested by clinical stories. There was a significant deficit in the function of the dopamine reward pathways in individuals that have ADHD.
FLATOW: So, you felt more reward if you got - if you're focused.
Dr. VOLKOW: Well, it's - what we are finding is there is decreased activity of the reward system in individuals with ADHD with which translate into a decreased sensitivity to being able to be engaged…

Despite it's wide spread therapeutic use over the last 50 years, little is known about how Ritalin works.

A review of over thirty neuroimaging studies on children diagnosed with Attention
Deficit/Hyperactivity Disorder (ADD, ADHD) by Giedd, Blumenthal, Molloy, and
Castellanos (2001) is organized around tables listing the main findings of studies using
different types of neuroimaging. Like most researchers in this field, Giedd et al. conclude
that the evidence supports the involvement of right frontal–striatal circuitry
with cerebellar modulation in ADHD. However, Giedd et al. do not report on a confounding
variable of crucial interest in this field of research — whether subjects had
been previously treated with stimulants or other psychotropic drugs. In the present
paper, we have redone five of the tables from the Giedd et al. review, adding information
on the subjects’ prior medication exposure, as reported in the individual studies
included in the review. We found that most subjects diagnosed with ADD or ADHD
had prior medication use, often for several months or years. This substantial confound
invalidates any suggestion of ADHD-specific neuropathology. Moreover, the few
recent studies using unmedicated ADHD subjects have inexplicably avoided making
straightforward comparisons of these subjects with controls.

I have this phobia of someone robbing me, or beating me with a baseball bat and not have a gun to protect my self. Does that mean I have a mental illness? Lol
No, not by itself. It certainly shows that enough people in this this society are mentally ill enough to blindy accept this as reality.
