I am sorry you started having this happen after your surgery! You have had good answers already. My son has seizures in sleep and his have been hard to determine with EEG. They do find some abnormality in both frontal and temporal lobes, so we feel it starts frontally and spreads. HE has been treated for this, but still does not have control for his seizures. When he has a seizure in sleep, he wakes up feeling really foggy and his thinking is very slowed. We can tell that is is "off", just not his normal self. We have seen his seizures on occasion (not as often now that he is a teen). He also has a sleep disorder, complicating things immensely. He is often sore and achy and sometimes bites his tongue, but not always. That link really describes the variables very well!

I hope your neuro gives you answers and help!
