60 year old male had grand mal 15-25 years old

I had grand mal ( I guess is now referred to as tonic clonic) from the.ages of 15-25. Wanted to know anyone else has the same similar experience. I am beginning to wonder about the lasting side effects? Wondering about a damaged hippocampus, permanent memory loss, and even PTSD from the multiple episodes that I had. Any feedback would be appreciated. Thank you. Tyler
