I just had this happen yesterday. I went to the ER, because, well, although I felt otherwise fine, it's a little scary.  My timeline:

:00 noticed blind spots (my aura)

:10 went to pharmacy to get a refill on Imitrex (blind spot was not very big, usually meaning a large migraine for me...bigger blind spot = less severe migraine)

:20 took Imitrex

:45 after laying low for a few minutes, felt pretty good.  Typed a few emails, no problems...minor headache, migraine aborted?

1:00 called someone.  After three sentences realized the words I was hearing myself had no resemblance of what I was thinking and trying to say, nor did they make any sense.  Syllables, vowels and consonants were all in tact, as were the natural rise and fall of language.  

1:10 Went to the ER, speech was already improving.

1:20 Saw the Dr., still struggling for a few words, but knew when something wasn't going to come out right.  Could say the first letter but knew the rest of the word was going to be off.  Dr. said it was likely a side effect of the generic Imitrex, and that I should inform my pharmacist.

1:40-2:00 speech was normal, headache minimal.  Still had the "afterglow" headache as I call it, but otherwise feeling fine.

The headache was NOT severe at all.  I'd put it at about a 3/10.  Imitrex has never worked that well, and am a bit suspicious if it was Imitrex or an atypical migraine.  

The closest thing I've found is Expressive Aphasia, which is what my doctor mentioned, but that involves normal syntax and substituting words.  I was speaking a different language.  Pitch inflection and rate were all normal, as were sequence of vowels and consonants in a western language, but it was absolute jibberish. 

For instance, I called my wife to try to tell her I was going to the ER.  I was heading to my neighbor's house and wanted to inform her.  Afterwards she told me I kept saying "Wybgonish, Wybgonish!"  I know that I was trying to say "Raquel."  I finally got out purple correctly, the color of my neighbor's house.  I could also say "I love you" with crystal clarity.  I have not found anything online to explain this.

Interesting, huh?  I wish I would have the presence of mind to record it.  I would have loved to see if there was a pattern.  

Any idea what happened?

I had this yesterday!  I may have had 1 migraine in my life and yesterday I had a minor headache with blurry peripheral vision.  I am 6 months pregnant and I took 2 tylenol.

My vision corrected after about 30 minutes and my headache had eased.  My husband, daughter, and I got into the car to drive 5 minutes to Thanksgiving dinner.  I tried to communicate to him that my headache was almost gone when I noticed my apraxic speech.  I knew exactly what I wanted to say but my motor movements of my mouth did not match what my brain was telling it to do.  I was trying to say 'migraine' and I said something close to 'pigrin'. My husband kept saying to calm down that it's anxiety but I was able to say 'no it's not' perfectly.  But when I attempted to ask if this was a symptom of migraines everything was jumbled. My pitch and rate were normal also. This lasted for about 2-3 minutes.  It scared me so much that I just stopped talking. I am a speech language pathologist and I work with pts who have aphasia and apraxia but it really scared me.  My speech eventually became normal and I had a little headache for the rest of the day.  I have never had anything like this happen to me and it was extra scary because of my pregnancy.

Glad to know I'm not crazy!  Actually, I've only had one definite migraine since then, and it was also the same apraxia-type.  It was in the middle of the night, my wife and I were awakened by a thunderstorm.  I mentioned to her that I had a bad headache, and she said "that made no sense."  I tried to rephrase only to find I wasn't making sense.  I tried to form words very slow, with little success.  This the point where she told me to be quiet or go to the emergency room.  I went back to sleep.

I had what I believe was a migraine one day while teaching, but am not fully sure. I was having more an aphasia problem, find the right word to say.  I had a lot of trouble saying the alphabet.  Later that day I went into my office, turned off the lights, and I could say the alphabet with little trouble.  I had a mild headache, in the same area as my usual migraines.

I had a CT scan in March, so no real concern with masses or aneurisms or anything.

Interesting stuff!  I am supposed to have a neurologist appointment sometime, but just haven't connected with the office.

Also, during the first migraine, I was able to say "can't talk", "Holly" (my wife's name), and "I love you" (to my wife) perfectly.  That latter is not exactly the thing to say to a loved one when you can say nothing else.  Holly took it as "this is it."  Funny now, but not so much then!

I had the same thing happen but I replaced words that i wanted to say with words that didn't make sense. 2 days ago after a migraine (mostly bindspot and nausea, and litle pain) I had to answer the phone for work and I couldn't put my thoughts together. I made conversation but I struggled with it as if forming the words were an effort even though I know my job well. I've suffered for years with migraines and food allergies and stress trigger them. But these "stroke like" symptoms scare me. I use holistic medicine for most things but was seriously thinking of going for a brain scan for a possible tumor! Why does

no one know much of anything about migraines?!

Hello,

My name is Mauro, I reside in Arkansas, and I have the exact symptoms that you have just described.  It has been no fun what so ever from the past five/six years.

In the beginning the doctors were thinking that I was faking it, just to have attention.  Now I have an excellent neurosurgeon that is taking care of me

At times my speech gets so bad that  is really embarassing, I stuttered and I have to stop. There are days that I just sleep.

Thank you for give me the chance to describe my case

truly yours

Mauro
