Responsive neurostimulation (RNS) as an epilepsy treatment?
I am wondering what experiences people have had with RNS. My son has had seizures since he was 7, has tried several different sezure medications and is currently on Brivacta, Onfi, Oxycarbazepine & has a VNS. Still having 4-6 seizures a month. RNS is our next hope, so if anybody has any personal experiences or info. I would greatly appreciate it. Thank you Casey.

1 ReactionHi @absentsenior,
That morning you described — feeling completely lost in your own home — sounds truly frightening. I'm very sorry you went through that.
I also didn't do well on Trileptal. It caused low blood sodium and very low blood pressure for me, which brought on dizziness, fatigue, and confusion. Like you, I tend to be very drug-resistant to traditional AEDs. I hope the titration process brings you some relief soon.
I'm also glad to hear you have a sister who's such a steady source of support through all of this.
I also want to acknowledge your retirement. Twenty years of relationships with people who became friends isn't something you walk away from lightly, even when it's the right call for your health. I understand those feelings well — I went through something similar in 2019, when I felt I could no longer provide quality service in career management and outplacement, and chose early retirement myself. What helped me was staying active and putting time into things I'd never had space for while working. My door as a career consultant closed, but others opened later.
How did the call with your doctor go — did he or she say your confusion might be a side-effect of oxcarbazepine? Have your blood sodium and pressure levels been checked? I'm also very curious to know if the RNS has altered your seizure patterns and how you have been adapting to it.
Sending you lots of strength,
Chris

Just a quick comment. Trileptal is the reference brand of oxcarbazepine.

I went into mayo today to the have blood drawn, and a walking e e g attached for twenty four hours. I made it a point of having my neurologist check my sodium levels at the same time and the results came back dangerously low. I called him to find out what to do and he advised electrolyte water, high in sodium, and to drink less plain water. We live in the desert and we are accustomed to drinking a great deal of water. Before the appointment, I had looked into the drugs, and he also put me on clonazepam in conjunction with the trilipdal for ten days to try to even me out. I did tell him that any drug that was capable of doing that to me. I didn't think was good for me to take. I saw him for a moment today when he came in to check on me during the EEG attachment. His nurse had not been clear to him about the severity of the situation. He and I have a very close and open relationship. I am hoping my memory comes back and that it's not gone for good. But only time will tell. I went to my naturalist this evening to get supplements. That would better support my sodium and that just needs a few days to correct itself. I appreciate your concern and would definitely tell anyone else thanking about trilipol or oxcarbazepane to think twice and to always research a drug, and it's possible side effects before ever putting it in their mouth, they also need to check it's interaction with their existing drugs. I will cover we always do. Thank you.

Thank you for sharing all of this!
I'm relieved your sodium was checked and caught, even though the result was so low. And I'm glad you and your neurologist have such a close, open relationship — that really does make a great difference!
Trileptal (oxcarbazepine) works as a sodium channel blocker, and I already tend to run on the lower side with blood pressure — so it lowered it further. It was actually through that experience that I learned low sodium is one of my own seizure triggers, which was an important thing for me to understand about my own condition. My medication was eventually changed to one that doesn't work that way.
It sounds like you and your doctor are already actively working on the sodium and Trileptal connection, which is reassuring. Out of curiosity, how has your blood pressure been through all this?
I see you're already titrating down the dose. Out of curiosity, has your doctor mentioned trying an anti-seizure medication from a different therapeutic class, one that doesn't work as a sodium channel blocker?
I hope all the changes help support you as you recover. Sending you much strength while you wait for your memory to return.🙌

1 Reaction@santosha i'm sorry it's taken me so long to respond to this. My reaction to titrating down on the oxcarbazepine was not a good one. It came very close to putting me in the hospital. But instead, I want to stay with my sister for a couple of weeks, which for me, was a better environment. I worked to increase my sodium level, but nothing worked. So at the moment today, I have chosen to go back on Keppra. Not something I'm looking forward to. As it tends to make me and not very nice person. But my neurologist suggested I take vitamin B-6 with it to see if that has an impact, I am somewhat frightened to be titrating up to a full dose of the keppra, while I am still add a full dose of the oxycarbazopine. In truth, I'm somewhat terrified of the combination, but I am more afraid of titrating off of the oxycarbasophine. Like so many of us I'm stuck in the position of having gone through most of the pharmaceuticals to treat my epilepsy
But I have to have faith in the team that's caring for me, and be very grateful for a neurologist who truly listens to me and trust in his experience and judgment. And I need to give the RNS it's chance to learn and handle more. I'm grateful for it because at the worst of this that device told me I was having a great many more seizures but a large number of them were not breaking through, because that device is learning and starting to do its job.

1 ReactionThis note is posted many years after the original start of this conversation. It is now September of 2026. I underwent RNS surgery about 6 months ago. At the Mayo clinic in Phoenix and the surgery sounds scary and some what extensive. But is actually fairly easy to go through. The device actually sits between the skin and the skull and not beneath the skull. Only the leads go down further into the brain. The leads are what help the RNS do its job
I upload the data to the Mayo server every morning, When I have gone through a bad spell, and so I did, when I took the oxycarbazzapan, and I knew that something was wrong. I messaged the doctor keeping an eye on the RNS uploads and asked her to check it. And when she did, she was able to see that I was having a great many more seizures at the moment. But the RNS was doing its job and stopping most of them before they reached a full blown level. That was only after 6 months. This device can take a year to almost 2 years to become fully effective because it learns as it goes, and eventually it is able to sense a seizure before it even starts and will send out a pulse to stop it. It takes time for it to learn. But after six months, it's already starting to send out a pulse to stop the seizures before they become full blown, and eventually we'll learn to stop them before they even start. There is no sensation to the pulse and other than the texture on my head. I wouldn't even know a device had been installed. That sounds very mechanical and to some degree. It is, but it has caused me no discomfort. And in this case warned me before I had to be hospitalized. I hope this helps anybody who is considering this surgery.
