I guess you are right. They know she will collapse at anytime, so she has people around her, ready to catch her.
The first time I had a seizure, I fell like a tree into asphalt. I assume she had that happen to.
I never hurt myself in a seizure but I did fall off a dock once and got fished out of the water by a couple of guys on the boat tied up right there. A deputy who was present wanted to arrest me for drunk and so I had to pay for an ER visit as a condition of not going to jail.
