It would be these events were I'd get the deja vu, the feeling of having a memory of experiencing something before, then tingling from the right shoulder down my arm to when it hit my fingers I'd feel a little hit in the head and lose words. That part is the seizure. I didn't know that was a type at all before looking it up online.
These episodes grew over time too. That first I remember on a bike, the next was when reading a book and I was so confused where the words went and why I could only see symbols. Since it's the temporal lobe, only words. Though I talk to multiple people, like my mom, she says there were times in the past where, when talking to her, I'd have to say hold on and sit in silence for 30 seconds before being able to comprehend again. Eventually got to an every other day frequency before being told that those events could be seizures and I should get it checked out.
In terms of seriousness, it's hard to say when that happened. I was told it looked like the benign DNET tumor and baby seizures that stopped with some drugs and I thought that was pretty funny how that happened to me. But then side effects from the first drugs kicked in and I had to switch. And then side effects from that drug kicked in and said screw it and have the surgery to get ride of the tumor and hopefully the part causing the seizures. Well that didn't work out, I still have different drugs and problems with those, and turns out it's a cancer tumor. Quite the turn.
The seizures themselves aren't too serious, because there are drugs to stop them, but the side effect problems are the big part.
