Here's a typical story from a parent's view.
"These seizures frighten me. They only last a minute or two but it seems like an eternity. I can often tell Heather's going to have one because she acts cranky and out of sorts. It begins with an unnatural shriek. Then she falls, and every muscle seems to be activated. Her teeth clench. She's pale, and later she turns slightly bluish. Shortly after she falls, her arms and upper body start to jerk, while her legs remain more or less stiff. This is the longest part of the seizure. Finally it stops and she falls into a deep sleep."
