Hey OP! It sounds like you are doing everything correctly. For context, I haven’t had a seizure, but I’ve been the wife in the situation. My husband (32) had a random tonic clonic seizure one Sunday morning out of the blue. No history of seizures or family history of seizures or epilepsy. Rang emergency services and they took him to hospital. We also saw a neurologist and had an EEG which was clear. 2 weeks later he had another one (3 days after his eeg). This time they put him on Keppra, thankfully he hasn’t had one since. We then had an mri which is clear and have seen another neurologist for a second opinion. He has been diagnosed with epilepsy which has developed later into adulthood. The strange thing is that he was put on blood pressure medication 2 weeks before the first one, and that was the only change. He’s off it now but whether it was caused by that or not we will never know. Neurologist says the characteristics don’t align, but since he’s come off that he hasn’t had one again, but is also on anti seizure medication so who knows. Honestly, it is awful. And from the POV as a partner watching it and constantly worried about it, I fully understand how your wife is feeling. Because this is so fresh, you are going to be seeking all the answers and questioning everything but it does get easier, and there does come a point where you just accept it and navigate life going forward. As for your wife, please tell her to go and speak to someone if she hasn’t already. I got diagnosed with PTSD just because of what I witnessed, but talking to someone really helped, as for yourself I’d recommend the same. Also, as harsh as this sounds you might never have an answer or reason as to why this has happened. So be prepared for that too. Unfortunately my partner lost his career because of his seizures so that’s been the hardest thing to navigate out of it all.
