I never knew about how CSD spreads but that makes sense. I don't see artifacts with my auras. Generally everything becomes too bright and too loud all at once. I know I'm having a bad one if I start writing backwards (I will write the second letter of every word first) or slurring my speech. Thankfully I don't get super bad ones as much anymore.

Ouf! Lucky for us, both our migraine severity seems to lessen over time. My brother had symptoms more like yours, speech slurring or limb movement impediment. Because theses are also seizure symptoms, we had to go to the first aid a bunch on false alarms, but luckily it was always 'just' a crazy migraine.
