@memoriestomoments Good Morning
Welcome to the Epilepsy & Seizures group — I believe this is your first post here. Thank you for sharing your experience with us!
I'm truly sorry for what you and your husband have been going through. I can relate on a personal level, as my mother also has Alzheimer's — it runs in her family as well.
Epilepsy is known to affect some people in the later stages of Alzheimer's. And as @jakedduck1 has well noted, roughly 50% of EEGs in people with epilepsy come back normal — so a clean EEG does not rule out seizure activity entirely. I experienced this myself, only receiving my epilepsy diagnosis many decades after my seizures began.
Has your husband ever been seen by a neurologist with expertise in epilepsy? That specialized perspective might be valuable.
Wishing you and your husband all the very best 💜
Chris
