See, I was thinking the same thing. MY husband mentioned getting an MRI to his doctor but his doctor said that he is not convinced he needs one yet since the episodes he has come and go. He said that if he was having a brain issue the symptoms affecting his speech would be constant. But I have a problem with that because people that have early Parkinson's disease for instance, have intermittent shaking problems throughout the day and that's a "brain" problem.
Have you ever seen a patient with type of problem? Do you think it is a tumor? Olfactory nerve damage?
