My migraine always comes with zigzag colorful ribbon, tingling in my right hand and the right side of my tongue, and disappearing areas of vision as you describe. My speech is also affected -- incorrect words or garbled words come out of my mouth when I try to talk. The symptoms are quite stroke-like -- it sounds like there's actually a bit of a continnum between migraine and stroke, with TIA (transient ischmeic attacks) in between. I did get scanned after my first one though and no damage was visible. Thankfully, mine only last about half and hour, and only seem to happen once a year or so. It's such a weird experience that I tend to forget how strange it is between occurrences because it's hard to believe the memories.
