Cognitive dysfunction edits.

Here's a rough go at finishing up the discussion.  The in-line references need checking to make sure that they have a paper associated with them, and I know that some of them probably need to be added, but cognitive dysfunction problems are making that challenging still, and help would be appreciated if you have some time for that.

Additionally, I don't really trust anything I've written since I got the new graphs and my ability to self-evaluate content is shot as the entirety of chapter 1 is reading as way complex and confusing at the moment, even though I know there were bits that I had written that had actually made sense pre-flare.  If you could scan the results and discussion in particular and see if there is anything that stands out as being absolute gibbering nonsense, that'd be helpful too.  It would be useful to have some objective frame of reference to how I'm actually performing at the end of a flare with cognitive dysfunction.
