my fiance had wahat was diagnosed as a TIA in december 2010. she had left sided facial drooping, impaired cognitive function, and "cold" centralized headache. the symptoms cleared in about 45 minutes. ischemia was confirmed via an MRI. she has since had recurrent "TIA'S" , sometimes 4-5 a week. She was diagnosed with a PFO while in the hospital and placed on coumidan 10mg. she is at 3.0 where her internist wants her to be. I should mention it took 3 months to get her to this level. Problem is she continues to have episodes. Let me describe her symptoms for you. Her local physician and cardiology at shands hospital do not believe this is cardiac but possibly auto-immune in nature. Her symptoms include: headaches, night sweats, very low tolerance for heat, frequent numbness in lower extremities from the knee to the soles of her feet, unsteady gait, temporary loss of vision in her left eye (returned in 3 hours but isnt the same)., a "wooshing: feeling across the top of her skull, tremors to only the right hand and only sometimes, short term memory loss, extreme fatigue, knee pain, bilateral arm numbness, numbness in the left side of her throat, left sided face pain.. She remembered back a few years and recalls some of these same symptoms once or twice within the last 3-4 years but they passed and she thought nothing of them. She has had an MRI, CT SCAN, xrays, TEE, 24 hour halter (normal), EKG, corotid ultra sound, venus doppler, and full blood work up and they found a vitamin D deficiency so far. She is awaiting a neuro consult and the remainder of the bloodwork to be evaluated. Any comments or information you can give will be apprteciated. We are both in the medical field and are stumped.
