My grandmother is complaining of these symptoms for about 6 mo. now. She just has what I call a "sinking spell" with extreme weakness and lethargy. She too has trouble remembering things but only during the "spell". She also says "she doesn't feel right in her head" I thought she was having TIA's but they said no when she was admitted to the hospital in Jan and did every test in the book and could not find anything at all! She did have a neurology consult and they did MRI, MRA, doppler on Carotids, Echo, EKG, CT, you name it they did it!! The symptoms seem to go away for a few months and have now returned with a vengence! She fell a week ago and now they are more pronounced. Her family doctor has ordered a follow up ct for the fall and referred her to a neurologist. ANy ideas? I was wondering if anything like Vasospasm could cause symptoms like this.
