You also don't have to be an epilieptic to have seizures from light or movie/TV strobing and/or auditory stimulation. As well there are different types or kinds of seizures. I can go through an EEG just fine. No seizure activity was ever detected in the several I've took. Basically anything which overtaxes a persons sensory processing system can trigger seizures but the person may not realize what they are having. One such type is this which I've had about 17 years now
Stimulus-sensitive myoclonus is triggered by a variety of external events, including noise, movement, and light. Surprise may increase the sensitivity of the individual.
An EEG won't trigger it but a movie like say Lion King can. I don't go too the movies LOL. Driving through a wooded area in the winter where light flickers between the trees to the eyes or on the pavment can trigger it. Certain tones like a back up alarm, fire alarm, or classical music. Store PA's turned up too loud or with a prompt tone also can do it.
I just go into violent upper torso spams or seizures. Each seizure last a few seconds and as many as several a minute in a bad attack. No passing out though nor any feeling I'm going too. It is limited in my case to specific plces only including shoulders, upper back, and neck. But if I don't stop the seizures I can go into a kind of a brain fog of where am I. how did I get here, where was I going, loss of time, etc. It can also easilly be misdiagnosed as Panic attacts. Been there done that for several years.
I become extremely dizzy & disoriented with the “light between the trees” things as well. The other thing that really sets me off (of all things)...certain types of geometric patterns on printed commercial carpet.
I can stand in one spot and look at the overall pattern with no problem, but when I try to walk down a hallway, or through a large room (usually these types of patterns are in hotels)...I simply lose my bearings. 90% of patterns cause no problem...just a handful of geometric examples.
There was one hotel (in Missouri) that I loved, and stayed at every few weeks for business that was the worst. I had to look up towards the ceiling and put my hand under my eyes as I walked down the hallway to avoid seeing the pattern “move” as I walked. How odd is that??
The one on the farm gave me problems with weakness and sometimes I had to have my husband help me get up to go to the kitchen and such. Several episodes of vomit without warning. But that was well over 23 years ago and nothing since. I had about 3 months of problems but didn't bother going to the doctor....
Had EEG about 10 years earlier and the first was not normal, showed seizure activity that I was not aware of. The second one showed abnormal activity in Theta and Delta waves occasionally, but they said essentially within normal limits...so I guess it was not too bad...Those episodes are sure strange.
We had a snoodle (dog poodle/Schnauzer) that was a bad epileptic and the vet said as he aged they would get worse, went from a seizure lasting a couple of minutes and the dog must have had an aura, cause just before he would seizure, he'd run to whoever was in the room and then start. As he aged, they became 45 minutes long with loss of bowel and bladder and he got real strange...We eventually had to have him put down but he lived for about 10 years....
I use to have valium from my father for the dog after he seizured, his was clonic/tonic (grand mal) and the muscles would be sore afterword so I'd pop him a valium...Sometimes me too LOL. Valium is what we used in the hospital for post seizure patients...its a muscle relaxer...
Gee I wonder if anyone is normal, we all have something that goes fluey once in a while.
I remember the one EEG that showed seizure activity they gave me the strobe light flicker and I did have a sensation of movement outside of my body, but also have PPVA positional Paroxamal /sp vertical attacks so that was not unusual to me...Caused by an inner ear problem...
Your right there are many different types of seizure activity. Many types not known to the average guy or gal..
