Stands for "transient ischemic attack." No, it has nothing to do with M3s. It's sort of a mini-stroke, without the damage.
A most peculiar feeling. I was typing on my work computer when, suddenly, I could no longer spell correctly. A word like "care" came out "carecarelescare." Attempts to rephrase were unsuccessful - I couldn't think of an alternative.
So I got up to tell the guy whose work I was editing that I wouldn't be able to help. But the words came out funny. If I meant to say "Hey, I can't help," what came out was "Argh, my feet green." Finally I gave up, went back to my office. I thought perhaps that I was having a stroke, but I was able to raise my arms and smile, and couldn't remember the other two or three tests.
After perhaps 30 minutes it went away. Finally went to the hospital, which kept me for a night and day and diagnosed the above. I'm fine, except I'm in a special class now (hey, I heard that!), and, most regrettably, I can't fly for two years.
I do not recommend this experience.
