My first experiences as a child were weak arms and poor eye-hand coordination. I could not play the childhood ball games, although I could dance and walk well. I could not use my arms for hard pushing such as washing windows.
I was diagnosed many many years later after I got double vision and had an MRI and evoked potential. In the meanwhile I'd had dizziness and balance problems. I was dizzy frequently but had balance problems only at isolated times, I suppose when I was having an exacerbation. I had cognitive dysfunction on tests after my dx, but that improved with rest and less stress.
