Balance and Vision Problems: Possible Causes & Next Steps

Question
What can cause lost balance/ blurred vision? Had MRI/MRA brain/neck-echocardiogram-carotid duplex. ALL came back OK. This has been going on since Feb 5 ,when had to go to EMER RM for what they said was Vertigo.

Answer
that is a tough question.... it sounds like you have already had a big workup.....  certainly vertigo can.... I would want to know if thyroid, blood counts, blood sugar were OK also.  And what has happened with the symptoms over the last couple of months.  Depending on your age, a small stroke that may not necessarily show up on the imaging tests that you had.    Good luck with everything.....
