Autism & epilepsy

Saturday night our son had a  seizure & was  omitted to hospital so far everything has come back clear we are currently waiting on results from blood cultures 

we are also waiting to have an eeg done they did try to do this 3 years ago as he was having  absences but failed due to our son not being happy about having the electrodes attached to his head our  paediatrician at the time put it down our son just zoning out when not  interested in something

Lately we have noticed that when he has a meltdown he will zone out like he is rebooting 

reading on things about epilepsy that a lack of sleep & stress can cause seizure now that's going to be fun when he doesn't sleep & gets very stressed
