I think tapering down a bit might help you. I was on 2 of risperidone and found it effective. When I tapered off entirely at some point(off abilify) I noticed that my ability to read was slowly returning----one thing I noticed though is I was trying to read at a faster rate than I could and it helped to slow down my reading a bit. The thing I'll warn you about is your cognition won't magically return you have to really push to learn. The weird thing is that once I had to go back on abilify due to a relapse I didn't immediately fall back to the cognitive issues. Its like for me that risperidone/abilify was initially blocking the healing of my brain post psychosis and I needed a med break to restore my mind so its not like the meds were causing cognitive issues so much as preventing them from healing. Keep in mind there is supposed to be some negative effect on cognition for every break you have(for some people) so if you were put on a higher dose I can only guess that you had some sort of psychosis.
