Very interesting article, explaining the role of dopamine in ADD individuals. It states that a group of ADD adults showed a lower than normal level
of dopamine in the brain.
Apparently, the ADD research community has always known that people properly diagnosed with ADD tend to be substance abusers. The idea is that these
people use substances in order to achieve temporary normalcy. Recreational drugs such as marijuana, nicotine, alcohol, and cocaine increase dopamine
levels - an effect that ADD people would benefit from. (Of course, these substances also have negative effects and should not be considered a safe
way to counter the effects of ADD.)
The study provides a logical rationale for why ADD medications work.
It is interesting to note that the individuals in the study had never been medicated for their ADD. The study also included brain scans of ADD
children, and a DNA examination. It was discovered that a certain gene linked to dopamine appeared to be associated with ADD, as well as thinner
brain tissues in the areas that control attention.
