Each time I took interferon, it left me with Attention Deficit Disorder that was long lasting. Each treatment seemed to be additive. After my last treatment that ended in 2008, I ended up with full blown ADD that made me impulsive and seriously detracted me to the point that I could not read and process anything that was very detailed. I spent much of my career managing large software projects, so I was very lucky this didn't happen until after I retired.
I finally got so fed up that I went to see a psychopharmacologist. He prescribed Adderall and it has made a tremendous difference. My impulsiveness has disappeared and I can concentrate for long periods of time without getting distracted. I feel as I did before treating and I am even sleeping better and my memory has improved!
I want to share this experience in case anyone else has experienced ADD following treatment with SOC.
