Talk to Neuro Physician on Epilepsy

Five years ago, I experienced several seizure attacks, after which my neurologist prescribed Epival 250 mg twice daily, in the morning and evening. About two years ago, I experienced an episode of dizziness during my normal daily routine, so my neurologist increased my dosage to Epival 250 mg in the morning and 500 mg at night.

Since then, I have not experienced any further seizures or dizziness. However, I have been experiencing problems with memory, difficulty concentrating, and sleep disturbances. I would like to know what might be causing these symptoms and what you would recommend I do next.
