I don't recall most of my High school & college years, only a few things, now I have fewer issues. Some of it had to do with medication issues and a lot of it was the epilepsy itself.

I Hate That I Can't Remember Certain Things, But It's Normal For Us Because Of Our Epilepsy

Unfortunately, bad memory and memory loss comes with the territory of having seizures, whether it seizures themselves or the medication’s and or when the seizures are not controlled, or you have multiple different types of seizures, you can have bad memory and memory loss

Don’t feel bad . It’s part of the package, living with Epilepsy

Generally when I have a seizure, I don’t remember it and when I was going to school, I might stay up late studying but then I would have a seizure during my sleep and not remember anything that I had stayed up studying
