How does ADD works in the brain?

Information that is processed in our brains is done by electrical signals. The brain cells be situated next to each other, and are arranged in such a way that they can transmit signals to each other. Because every brain cell autonomous functions they are therefore not connected. They are separated by a cell wall and a small amount of moisture. To let the electrical stimulus not to lose it's strength, there will be a transfer of this signal taken place by a small quantity chemical blocks. As a kind of cannon, these neurotransmitters are ejected toward the next brain cell. When these neurotransmitters in the brain clash with a following brain cell, it's creating a new electrical stimulus wich follows it's way again. 


With ADD there is an error in the transmission of information between brain cells. There are not enough chemicals present so the electrical signals eventually will decrease in strength. The brain cells are mainly responsible for sensory perception. This means that the information that comes from the brain at someone with ADD, registered less efficient than the original information. It is no coincidence that people with ADD and ADHD, are both known for their high pain threshold. Especially parents with AD (H) D children are telling about their children regularly. Children can fall flat on the concrete, and then without giving a kick, scramble up on their feet and move on. Shortly, regular information by someone with ADD assessed as boring, and exciting or stimulating situations assesesed as normal. 
ADD has nothing to do with lack of attitude, motivation or willpower, people with ADD can not do otherwise because their brains put them on the wrong track.


The brain areas that are stimulated are also responsible for stimulating the production of adrenalin. Adrenalin is a type of drug that makes your body and mind sharp and alert. In cases of extreme danger your body produces a lot of adrenalin that makes you able to huge physical effort wich otherwise would not have been held. In the case of ADD there is also a lack of sufficient brain stimulance and also produce less adrenalin than is necessary. The problem is not that someone with ADD can not focus, but they can not concentrate at the times it is necessary (Verbaten, 2001)


In ADD, the information will be recorded but it takes longer to process and evaluate the information. Often, the evaluation of the information needs the reference frames. Therefore, it will not always be quick and appropriate response in certain situations where this is desired. Therefore the ADD-er is not always able to be perspective. It remains too long in a so-called emotional assessment. Because the emotion that the ADD-er feels is corrected or compensated  by rational thoughts. This is one reason why there is often at ADD a so-called Hyper Sensitivity (High Sensitivity). This can sometimes have advantages but also explains why the ADD-er is easily offended.
