When I first got sick 4 years ago I spent several months in hospitals including 5 weeks in a rehab hospital because I was completely crippled by a muscle disease, polymyositis. I needed PT, OT and speech therapy (could not swallow) and the speech therapist wanted to give me cognitive tests. I responded that my problem was that I was crippled and had nothing to do with my brain. Was I surprised.....the tests showed that I had short term memory loss and concentration problems. What the tests did not show was that I was much more emotional and had difficulty dealing with stress as well.
All of these areas have improved over the past 3 years but there is no question that lupus impacted my cognitive powers. It is much better to know what your problems are and learn strategies to deal with them in day to day life. I used to be a list maker who never needed them but today I do. I never forgot anything. Today I make sure I am prepared for anything I need to do and try not to solely rely on my memory.
I would encourage you to take the tests. If you do not you will always wonder and not do anything to help yourself with new strategies or exercises to help.
