Unexpected seizure
In our case all seizures are unexpected and I am not sure how I managed to get one on video but for a few brief moments while chatting with Matt he had a absence seizure you can really tell when he comes out of it and is confused.
Yes Matt has many different kinds again absence, drop and of course grand mal's it isnt my first thought to grab a camera to video one but maybe I will work on that more.
It isnt always easy to spot a seizure unless it is a grand mal so it is best to know the person and how they react, it has been over 15 years that I have been going through these with Matt so a little easier for me to know when and what type he is having.
