Does anyone know what causes/caused your epilepsy?

I’ve had multiple EEGs all showed abnormal when I was younger. I’ve had 10 seizures since the beginning of last year. When I asked my doctor if I could do more testing to find out more he recommended another eeg. It’s just gonna show abnormal again, right? I kinda wanna know why I’m having them or if there’s something wrong in my brain, what it is. Maybe that’s stupid so it made me curious how many of you know what causes your epilepsy?
