I agree that it would be odd that he'd be trying to have a sz since cognitively he doesn't seem that he'd understand to do so. Alot of people that have sz's also can become aggressive during the sz which may explain his reaction when you try and interrupt the sz.
I saw this and just had to post too. I have read that patients that have a seizure disorder have nonepileptic seizures too. In fact, it is quite common in epilepsy. I have also read that it not a purposeful act, not "faked" for attention, although there are episodes that can be, especially in individuals that are under stress.
I have even told my own doctor that there are times that I don't feel right and I'm not sure if it is a seizure or not. I know what a typical seizure is like for me, but sometimes I have times that seem not to "complete" the full episode. When I had my VEEG, I welcomed the chance to see if what I was experiencing was a NES or not. Sure enough, I had one that didn't show up on the EEG. And it was one that didn't "complete" to the full episode. The doctor said it might have been an aura that the surface EEG didn't pick up. But I couldn't help suspect it was one of those NES. The only way to find out is to have a deep electrode EEG.
Bottom line is... we, as caring individuals, WANT to help someone by diagnosing someone. We see what they go through. If they are in pain or suffering we want to fix it. Mental retardation and the behavior that results are difficult for normal folks to understand. That's why special ed teachers have special training, God bless them!, because their behavior isn't what most of us would expect or could handle.
Normal people might accept the concept of NES in normal people. But I don't I know the reason for a mentally handicapped child of 7 to have a NES. I feel that's for the doctor/psych/therapist to figure out. We might want to call it a seizure or whatever, but if it's something that's causing a problem, it's best left up to the doctor for diagnosis and treatment. KrisMuro is right to have concern about his behavior - any symptoms should be reported to the doctor that are problematic. But it's trying to make the diagosis that we, as lay people, should stay away from. Leave that to the doctor.
