I Was Diagnosed With Seizures And Migraine Recently. Many Years

I was diagnosed with seizures and migraine recently. Many years ago I was told that I had adrenaline insufficiency and depression. Are any of these illnesses relation related? This started after I had a serious case of hepatitis I am 70 years woman and the hepatitis was 50 years. My diagnosis have piled on since that 1st illness. No doctor has been able to make a connection ?
