This is an interesting question.

In the early stages of my MG, I suffered from severe cognitive dysfunction.

I had severe memory issues and I had illogical thinking. My neurologist thinks that I was on too many drugs. I think that my reaction to these drugs (ambien, clonezepam) was so severe because they caused respiratory suppression. I think that I must have been a little bit crazy to listen to the doctor that prescribed them.

I guess that it is also possible that the cognitive problems were caused by the MG.
