Since fall of '97, I have had "episodes" of extreme weakness, sometimes paralysis, occuring mostly on the left side of my body. They last anywhere from 20 mins to a few hrs, 1-3 times/mo to none for 2-3 months.
An MRI indicates that I have a long, enlarged vein in my brain's right parietal. The only other thing that's shown up after many tests is that I am again hypothyroid. [note: in 1990, my thyroid stimulating hormone (TSH) was over 97.0, yet my bloodwork, until now, had been fine for 5 years without medication.]
In defense of the doctors' choices, I have wrestled with depression, from age 17 to ~40. But also during those years, I wrestled with extreme migraine, which a hyster/oopherectomy in 1990 almost completely eradicated. The depressions are also now manageable, and I've never been happier.
In spite of a potential for herediting Types I or II Diabetes, I haven't been diagnosed with it. In fact, I am in pretty good shape at 50 other than these persistent and mysterious "episodes."

My questions are: Why have 4 GPs continued to send me for psychiatric drug treatment instead of considering that my brain may physiologically be accountable for the "episodes"? And, do I have to have a full-blown stroke before they will believe that I am a stable, happy woman who's baffled by inconsistent health.
