The ADD Serie - How do it affect people concerned?

Hi again :)

Because it is really hard to explain how ADD affect people concerned I just will write what's coming in my mind. ^^

So I didn't eplained why AD(H)D people have problem with concentrate on thing. So here a explanation. 
Well you could say we have a damaged brain, but actually it isn't...it just works not the same way than others.  
The easiest way to explain it then is with a "filter" door. People without AD(H)D can close this door when there are unimportant information and open it for important stuff. A person with AD(H)D can't, the door don't exist it's just a doorframe and every single information can go throught.
