I think the words I want to say, but, it's like a short-circuit, and when I try to say the words, they don't come out like they are supposed to. They may come out in part, with missing letters or improper sounds, or the syllables may not be in proper sequence. In a couple of cases I couldn't get the word out at all. It's almost like the aura itself, only words with holes in them. This lasts about as long as the aura, anywhere from 15 to 45 minutes. It feels like you are in a time warp!
It was scary the first time it happened, because I thought I was having a stroke, but there were no other syptoms, and, of course, I was back to normal after the 15 to 45 minutes it lasted, save the residual pressure part of the headache that continues longer. Have had three episodes this year.
Side note is I have ELS (Lupus)
