Experience with severe seizures alleviated with surgery

Hey all! Usually, I don't like to post something general and rather undefined, but I don't want to read a general summary on google, I want actual stories and opinions... Well, I suppose that's a pretty bland statement for not asking anything yet... So, I want to know of an incident where someone was fine for a while - seizures mild. Then progressively got worse until they ended up hospitalized and in a state of constant seizures/recovery from one until surgery. What is this called? How does it happen? "What's the time frame? If I know what it's called, I can do some research myself, but if you have anything you want to share about your experiences, please tell me. I'm writing and I want to be accurate and not soap operah-ish; have a story line that would happen realistically. Please, if you have the time, point me in the right direction. Thanks for your help!!! Caboose.
