I am having a CT scan on Friday to see if I have an aneurysm. I had 2 seizures in December of 2008 and while at the hospital, they did 2 CAT scans and an MRI. Both were normal. I suffered a mild traumatic brain injury while having the second seizure because the bed rail was not up on the hospital bed. I am wondering if it is possible to get an aneurysm from a fall? I have none of the risk factors except that I am a woman over the age of 40. I know nothing about this, so I am just throwing this out there. Can they happen suddenly? I would have thought that may have been something they would have looked for when trying to find out what was causing the seizures.
