Hi, Tevlock!
I hope today is better for you!
re: your SPECT scan - I hope it turns out good for you, whatever that is...I say that because I had one and they told me that together with my memory problems and an abnormal SPECT (frontal, parietal, temporal, (and one other region of the brain that I forget today) etc. I had Alzheimer's.
So naturally, I started on second and third opinions as in the 4 years since then, I have not gotten worse as typically expected. Bottom line: take a deep breath and try to relax when you get the result and then come here and tell us what it is!
