I'd really appreciate some help on this, any input at all. I suffered a viral illness that crept into my brain over a year ago, which was, how shall we say, not the most pleasant experience to go through. I've been to neurologists and I've had an MRI, but there was a long delay in getting a diagnosis; the recent MRI I got has come back "normal", which is frustrating to me, given that I have to live with the headaches, brain fog, fatigue, and permanently damaged vision. I've also had a "visual evoked potential" (VEP) test, which to my shock came back "normal". I mean, my vision is absolutely disastrous (my eyes themselves are physically fine) so I thought the VEP would surely detect some damage. But it didn't. So now I'm left with the question: is there any other test, perhaps a SPECT scan or EEG, that might be able to pick up some sign of the damage? Can anybody suggest what the next step might be? I'd really appreciate it, it's important to me to get some physical evidence for this.
