Is it possible to have a "normal" MRI scan and have a possitive spinal ?
Just wondering about the stats on this. And also if you have had seizures do they aways show up on EEG's ? Thanks.
Neither an MRI or a spinal tap are a conclusive test for MS. They're used to determine all kinds of other disorders...one of which might
If you have a "positive" spinal tap -- you'd need to be more specifically what you're "positive" for. If there are o-bands, then maybe MS. If there are elevated levels of other proteins, then possibly MS, but maybe some infection somewhere in the central nervous system.
MRI's are like "pictures" of your brain -- and can be interpreted differently, depending on the experience of the doctor, the clarity of the MRI, how progressed the disease is. Sometimes in very early stages of MS, the lesions don't appear. And sometimes they're there, but a doctor misses them.
As Rhonda said, seizures will only show up on an EEG if you have a seizure while hooked up to an eeg machine. There are some portable ones that people "wear", if there is some suspicion that perhaps they're having minor seizures.
That's why a doctor needs more than just a "positive MRI", or "positive spinal tap" to make his diagnosis of MS. He needs at least one of those, and then clinical signs -- things that can be tested for and demonstrated and are quantitatively measureable (not things you "experience", or "feel"), and some specific signs that are "MS-like" -- balance issues, weakness in a limb, that sort of thing.
While some folks with MS do experience seizures, seizures are not one of the more common signs of MS.
