hmm lets see.. meds i would say cld be a cause.. but RSD and chronic pain can cause spas moments i call them but it affects our memory our focus. now I stuttered as a kid and am dyslexic as well both of these take discipline to maintain even though its been years. but my vocabulary , math and science skills have always been easy to me. now my stutter comes back when i cannot think of the words I need or when flare and stress peek. and my math and logic skills keep me questioning myself. I thing it is the RSD and chronic pain messing around with our computer we call brain i mean hello it is neurological and all these signals go through our brain so it is logical that our signals are creating too many signals and are over loading our brain. think of it how often do you get confused NOW as apposed to before.
