Your question can only be answered by a doctor or someone with medical expertise in that area but whatever the answer is, I think having a seizure from alcohol withdrawal is a sign you've hit the end of the road and it's time to turn around. No more drinking. Period.
Easier said than done but you'll find support here. Hope you're doing better today and continue to improve over the next week or so. Be sure to make a follow up appointment with a doctor to discuss any other concerns you have about what has happened.
