There are many types of seizures.
Before we started on this journey, I was only aware of two.
I watched a classmate have a 'grand mal' seizure in high school.
I had heard that sometimes when people appear to be daydreaming, it could be a seizure (absence seizures).
Ben has 3 different types of seizures.
Tonic clonic: used to be referred to as 'grand mal'; lots of convulsions; most often he completely stops breathing; usually sleeps for at least an hour after each one
Myoclonic: his arms jerk upward around his face; if he's holding something, he drops it; will often make him fall backwards
Atonic or Drop: sometimes it is slight - his head will just drop forward; will cause him to fall forward;
