While this is great, I’d like to also add that their are more than one type of seizure, and more than a few different ways they exhibit themselves (in a physical sense) before I grew out of mine, my seizures were known as “absent” seizures. As far as symptoms go, all that was visible was apparently a blank stare. I was no longer responsive to stimuli of any kind during this seizure. It was just simply a loss of input, really. I do believe that I had become unable to physically support myself during some of the seizures, because of my parents alarming reaction whenever a bottle falls when I’m in the shower. I think I might of had an attack in the tub/shower when I was little. But…long drawn out story aside. Some of these seem to refer to grand mal seizures, but even if they aren’t all referring to that type, it’s the usual association people have to the word seizure. I’m just letting you know that if you go to the link on these pictures, you will find out that there are more kinds of seizures, and that lumping those with seizures into one type, isn’t just going to harm the perception of the condition, but it may harm how you handle the situation if you ever come across a friend/family member/etc having a seizure.
So TL;DR, go to the site, read up on the different kinds of seizures, and know that not everyone has the same kind/symptoms.
