I like this link very much. Although it does leave out many of the different symptoms possible with aura, it covers those most frequently experienced. No one will understand aura until they have experienced one however, and not all migraineurs experience them. They are a fascinating stage of Migraine Disease. Unfortunately, the narrator did not mention that taking medicine as soon as you experience an aura as important, I thought this link was very well done.

interesting, had some trouble starting it, but then it seemed to smooth out.

video is pretty cool
