My dh had a tonic-clonic seizure about two weeks ago. He had a brain, cervical, and thoracic spine MRI, and an 72 hour ambulatory EEG. His neuro said nothing showed up. He had more lesions since his last MRI, but they were already fading. His EEG didn't show anything. Neuro said it was strange for dh to have tonic-clonic seizure (he stopped breathing and was in the seizure for a longer than normal). He had simple partial seizures before, but nothing like this. The neuro said that he cannot link it to MS at this point so he has to treat it separately. Does anyone else have any similar experiences?
