I've read it somewhere too. It makes sense if you think about it. In certain types of ADHD, the hyperactiity is in the thoughts. So the person would have more thoughts racing through his or her head than normal and this probably constitutes the creativity since they have more random thoughts to seed a good idea. The drive for this is thought to be caused by understimulation. In other words the mind is bored, so we start racing through thoughts to try to make something more exciting. What Adderall does is stimulate your mind so that it's no longer bored. Less random thoughts are needed and the person can focus on one thing better. Of course, the random thoughts, which constituted the creativity, is traded off. It's actually my theory behind how it works (I have ADHD).
