I have seizure disorder (according to 3 neurologists) but getting the correct dx was a hard thing that took a lot of time and testing. It has never shown up on an EEG (and I have had 3 of 'em) and every MRI and PET etc has shown nothing. What I have always wondered is how can doctors diagnose one person with epilepsy and the next person with pseudo-seizures when both people have negative EEGs? What happens if they stop someones meds for epilepsy because they believe they are having pseudo-seizures and they are really have seizures that really just never show up on tests? How do they make they make the dx with no concrete proof?
