This may be to late since its 2011 but I've had same problem for 16 yrs this week I had and echo with bubble done on my heart they found a hole in my heart which is normal in 25 percent of population but for me the pfo or hole in my heart causes tia or mini stroke there is a procedure that can fix hole but not approved by fda so not approved
I too went to the er with symptoms or dizziness, headache, left sided numbness to the point I couldn't pick up my arm. I began to stutter and couldn't remember how to do simple things like when I went to eat lunch and pay with a check I couldn't remember how to write the check. I was even having seizures. The rushed me to the er and they did a CT which came back normal. They kept me for observation for 2 days then did an EEG which came back normal. They then diagnosed me the hypothyroidism. And let me tell you I am 5'2" and weight 125 lbs. Do I sound like my thyroid is underactive? Not to me. But I am trying to find out what kind of Dr I need to go to now or even if they can tell if it was a stroke 6 weeks after. I still have the stutter and forgetfullness. I also normally have low BP like 120/60 pulse rate normally around 70. This day my BP was 160/102 amd pulse was 150-170. I need help too if you come up with anything.
Sorry to hear about your episode :(
If you are not satisfied with your diagnosis/treatment, go see another doctor. Since you don;t really know the problem, I would suggest a specialist physician - someone who can do a thorough all over work up. If you go to someone too specialised they may only see problems that are in their speciality & miss something important.
All the best.
I too, was hospitalized for 3 days. they ran a ton of tests, all came back normal. the last test they performened was an EEG on the brain. Several hours later, (9:30 p.m.) I was discharged by a nurse. They gave me a sheet pf paper indicating an TIA, the diagnosis was "Dysarturia Aphasia". The discharge papers said to do a follow up with the new Neurologist in 4 weeks. In the meen time I am still struggling w/my speach, slurring, garbled, and mis-pronounciation of words, it comes and goes, but effects me daily.
