Hi Trying! Welcome to CWE.

Like you, my hubby is fantastic and did everything he could to understand my condition, including going with me to ALL doctor's appointments.

As for your question....actually, that all depends. Myself, I never really had any issues while I was on phenobarbital..just tired. When I was on Depakote, I didn't have mood issues at all. But then again, it's a mood stabilizer. The doc is putting me on Dilantin now (after taking me off depakote and phenobarb....they quit working for me. And yes, meds can quit working.) and I don't have any issues. I've had friends on Tegratol who got moody at times...and keppra has a histroy of making some people irritable. For those on Keppra, it's suggested that they talk to their docs about a vitamin B-6 supplement. B-6 has helped alot of people deal with kepprage.
Now, thanks to the tonic clonics (grand mal) seizures, as well as the meds, my memory isn't what it used to be. But, Fish Oil capsules help. If your wife has just recently been diagnosed, she may be going through a bit of depression. Epilepsy does cause most of us to make some changes. For example, cutting back on caffeine, not getting to go on roller coasters, not being allowed to take baths by ourselves, and for some, not being able to drive anymore (that last one depends on which state you live in ). I had epilepsy before I married my husband. So he knew a little bit about it. But it did kind of freak him out when I had a seizure while we were dating. But his response was to ask me if he could go to my next neurologist's appointment with me. Ever since, he goes to all my doctor's visits, and sometimes, I think they like him more then me.

I know he gets along wonderfully with all the receptionists.

Anyway, at that first neurologists visit, he sat and asked all the questions he could think of. Including questions about my ability to have kids.

After we got married, we decided to go ahead and try to have kids, so back to the neuro we went. We talked with him, and he started weaning me off the depakote (danger of causing Spina Bifida). Also, I started taking 800mcg folic Acid everyday...just in case. I didn't realize it...but the neuro pulled him aside and talked to him about SUDEP, as well as the fact that I might have more seizures if I ever did get pregnant. And then we went through a couple of years where I started having more frequent seizures. My hubby would call off at work to take care of me if I had had a seizure. At one point, his boss asked him to choose between his job or his wife. My hubby told him where to go, and how to get there. The boss thought I was faking it. A couple of months later, when the boss realized he couldn't afford to not have my hubby working for him, they begged him back. And I ended up having a seizure at the boss's house. Freaked him out, and proved that my hubby had not been faking it. (And yes, discrimination like that can happen here in the US. Because alot of people don't know the basic facts about epilepsy. )
Now, we've been through a lot of stuff. And honestly I think some of them were more worrisome then the seizures. The seizures have actually caused some humorous episodes . (For example, seizures and sex.) As well as some worrisome episodes. (once had one and went head first into a firepit...where we had a fire going. Hubby ended up with burned feet from running through the pit to grab me out of it, and I ended up with a black eye from the chunk of red hot concrete that was in the firepit. Hubby got dirty looks for weeks after that whenever we went out together. )
Now, can the irritability be due to meds? Possibly. Every brain is different...so everyone has a different reaction to meds. Some, like Keppra, are known to cause people to be more irritable. If she's just getting on the med, that can be a time of irritability too. If she's been on the Tegratol and Topamax for a while, I would suggest she call her doc and let him or her know. Maybe her levels need to be checked and either the meds upped or brought down.
This is a great site for info. So feel free to ask questions, vent in the padded room, or just chime in . And invite your wife to check out the site. It's not unusual for people with E to feel like they are the only ones. The truth is, she's not alone. Over 3 million people in the US have epilepsy. 300,000 new cases are diagnosed each year. And in a CDC study, they found that 1 in 100 people has epilepsy. so she's definitely not alone. Alot of people with E feel like it's shameful and they hide it. Some people don't feel like there's any need to hide it. We have both groups here. Anyway, I hope this helped. Check out the Epilepsy 101 thread in my signature...it has some great basic info on E.
