My mother had a seizure last night.

I got a phone call today from my mother stating that she thought she had a seizure last night. She said she had woken up from a nap, and had let the dogs outside to go to the bathroom. As she was walking up the stairs to go to bed, she felt really dizzy. When she got into her room, she was leaning against the dresser to keep her balance because she felt like she was about to faint and fell over. For about a minute, she said she was convulsing slightly on the floor. When she finally stopped, she was in a state of confusion, but she said she was concious through the whole thing. This is the first one she's ever had. She's never even fainted before. She refuses to go to the doctor right now because she is getting married in one month, and does not have health coverage right now but will when she is married. I know she obviously should, but she is stubborn. My question is, and I know none of you are doctor's or anything, but I was hoping to get your advice on what may have caused it. Currently, she is pre-menopause and her period is extremely screwy. She had just taken pain medication yesterday before the seizure for it (I only know all this because I asked her, haha). She also quit smoking a month ago, and I assume that this would stress the body out somewhat. I also know she was under a lot of stress this weekend because her fiance had to go in for an emergency root canal and was in a lot of pain all weekend. Not only that, but I'm sure she is stressed out from the wedding in a month. Can these factors trigger seizures at all? I know seizures can be triggered from many things, including serious illnesses, but she has felt fine recently and even does today. This seizure seemed to come out of know where, and I was wondering if the cause of stress and menopause could cause this to happen. I really wish she would see a doctor, and she promises she will if anything like this were to happen again, but I was just hoping to hear other's opinions. Thanks.
