Coping with memory issues

I have had epilepsy for 57 years. Now I on a combination of meds that are both powerful and effective. I am currently on Zonisamide, Oxcarbazepine, Gabapentine. Seizure drugs work on the brain to control the many causes of our neurological disorders. Over time they are hard on each one of us differently. They are powerful drugs in our system that we handle everyday. My memory starting slipping slowly but as I got older it became worse. My neurologist has avoided the issue when I ask him about it. How are your seizure drug/drugs affecting you?
