I have noticed my own lack of ability to concentrate since I have been diagnosed. I believe some of it is due to our medication but I think the brain has been overwhelmed with pain receptors in addition to normal thought processes. I am making notes for my "to do list" so I don't forget; have handed my checkbook balancing duties to my husband, and generally force myself to concentrate on whatever is immediate. I live with my calendar in hand. This is a terrible disease; it is almost like dress rehearsal for Alzheimers
