An aura is a sensation or a feeling that a patient reports prior to a seizure. They can be visual, auditory, smells, nausea, changes in sensation, de ja vu, or any perceived feeling a patient has before a seizure. Typically auras only last for 5-10 seconds before a seizure. However in patients taking medications they could last longer. Based on the fact that you are having a aura indicates that you have focal seizures (means they are coming from one area), as opposed to generalized. Seizures occur at any age. The MRI you had was most likely a routine MRI, at epilepsy centers, such as the one at the Cleveland Clinic, special sequences can be done, and an abnormality may be found.
Some women notice that their seizures occur at certain times during their menstrual cycle, therefore yes hormones can influence seizures.
In addition to medication some patients can have surgery to try and prevent future seizures. However medications are the first line treatment, and until at least 2-3 good medications have failed surgery would not be considered.
I hope this helps. Good luck

My first grand mal seizure was at 31 in 2000. No known cause and my doctor missed 8 months of obvious signs of partial simple motor and senory seizures. I don't always have the exact same aura's. From extremely sweet smells, alcohol or penny taste, and visually, I have episodes of seeing things in slow motion as if things were moving in a strobe light. These are all examples of temporal lobe aura's as they arise out of the senses such as smell and taste. During a partial simple seizure I experience several minutes of not being able to speak, having loss of short term memory, severe headaches, numbness and tingling in my arms and sometimes legs. To some extent we all present differently. It is very difficult being diagnosed with adult onset epilepsy with no known cause but absolute EEG abnormalities. There have been links with hormone "causing" seizures and there is information on the web. During any aura/seizure there are "spikes and waves" going on in the brain. Understanding EEG's is another thing all together. We can always hope we won't be on medication forever :) Learning makes understanding much easier.
dizou, Thanks for the info.
What I didn't realize was that I'd been having petite mals since childhood (that feeling wherein everyone in the conversation suddenly begins speaking Chinese--rude of them, I know-- and rising panic at losing control). That was first diagnozed as panic attacks a few years before the grand mal slapped us all in the face and said 'Epilepsy! you morons!"
As far auras are concerned, I can't tell if I get them or not: I lose about an hour of memory preceding each grand mal. My point (I have one, really I do) is that a close questioning of witnesses to your grand mals can sometimes be helpful, to determine if you mention an aura-like feeling before you hit the floor, as in "What's that filthy smell? Whoa! (**goes for the carpet)"
Hope that is at all helpful. (Be advised I'm not making light of anyone's difficulties but my own. Some have denial; I have reflexive joking... whatever gets you through the day, eh?)
Cheers.
It is immeasurably worse if I have a few drinks the night before - but a couple of glasses of wine is OK. Also, coffee (which I now don't drink) also heightens it immensely.
My other symptom is the one which is really freaking me out. I am now getting this sensation of a tremor overcoming me when I am talking to people. It is as if I am going to clench up and fall into some sort of seizure. It has (until yesterday) been a very brief symptom, each time only lasting a second or two. Yesterday however, I was at lunch with a couple of guys I know and we were just talking. I was feeling just slightly off from being out with friends from Hong Kong the night before - dinner and about 5 or 6 glasses of wine. A little too much I know, but no big deal by long time standards. Anyway I had this sensation overtake me over about 5 minutes which left me shaking with fear. I was sure that I had very nearly succumbed to something very profound. It had left me unable to carry on a conversation or eat the other half of my lunch. I jsut got up and walked away, shakely. I KNEW I had just come very near to something I had never felt before - like I was just going to fall over in a knot of utterly lost control - again, a purely physical set of sensations - the conversation had been simple, friendly - the setting just a cafeteria.
Now it is happening several times a day, always when I am in conversation. As I said, I do not have a nervous, panicky, phobic frame of thought, of mind or demeanor. I am normally confident - a good public speaker - and I am not under any unusual stress.
Anyway, I am venting I guess. I am going to go back to my neurologist and fill her in on my "near-event" and the trend in this phenomenon worsening.
Any comments or knowledge of similar situations are welcome.
Thanks.
