Migraine aura is a wave of activity in the brain traveling through the
brain. The location of the wave of activity in the brain determines
the type of aura. The most common type of aura is a visual aura. About
90% of people who have migraine with aura have this type. It’s thought
that auras are usually visual because such a large portion of the
brain processes visual information.
If the wave of activity goes through other areas of the brain such as
the sensory or language centers, then the person would have sensory
(for example, tingling in the tongue, face or arm) or language auras.
The auras usually last for about five minutes to an hour. Aura can
sometimes occur without a headache.
A migraine aura that affects your vision is common. Visual symptoms
don’t last long. A migraine aura involving your vision will affect
both eyes, and you may see:
Flashes of light
Shimmering spots or stars
These symptoms can temporarily get in the way of certain activities,
such as reading or driving. But migraine with aura isn’t usually
Concerning, but probably not very serious, but it means that I can’t read text until it fades. It’s a very odd effect, independent of either eye. Kind of like you took a thumbnail to an LCD screen in an arc, except the arc starts in the center of my field of vision and expands outward.
Very distracting though, means I can’t do much of anything with vision until it goes away.
And it has COMPLETELY stopped happening since I stopped sweeteners, sooooo…
@EvilSmoo@werehatrack - Interesting!
I get optic migraines - kinetic arcs of shimmering patterns, but they’re more to the sides of my vision and without accompanying headaches. They’re really kind of a cool light show since they don’t last long.
Never thought about artificial sweeteners causing them, I have Ice Chips candy that I get from my dentist’s office which is sweetened with xylitol.
My thinking is, it’s all the same brain-storm of stimulation, if it happens in the pain center, you get migraines, if it happens in the optical center, you get vision distortion. Maybe it happens in other places as well?
I don’t want to make my own thread so commenting here:
Anyone else lose their daily meh emails? I did last week ish, and they’re not in spam folders. I went to my preferences and made sure I had the box clicked to still receive them but still nada. My brains not strong enough to remember to come every day! Maybe I need to chug a bunch of focus drinks to get smarter?
@sagergen it happened to me a long time ago, meh fixed it, then it happened again, and neither i nor they can seem to do anything about it. sad b/c my streaks are much shorter when i have to remember to click on my own.
@catthegreat happened to me last time, too. There was more noise in the forums about it then, but I didn’t see anything in a cursory glance today before I commented so I wondered if I was alone. Who knows
