I just got off the phone w/Mike and he said that since they started Bailey on the new meds, she hasn't had any seizures! So...they feel they've narrowed it down to either encephalitis or a brain tumor. The only thing that will tell for sure is an MRI and he's already stretched financially, so the vet told him that she feels that if Bailey continues to improve on the meds, that it's encephalitis which is curable. A brain tumor isn't. She told Mike that Bailey has a 50-50 chance. All in all, I'd say this is a much better report, wouldn't you?
