How necessary is it to have a CT head scan for having one possible simple partial seizure two months ago? I saw a neurologist who suggested I have the scan, but he did admit another neurologist might have said it was okay to wait and see if it happened again. He left the decision up to me. I'm worried about the x-rays of a CT scan, having had plenty of x-rays for other procedures in the past. If I have another seizure or whatever it was, I would definitely have a scan. But I'm wondering if, at this stage, it is safe to wait.
