One of my major cognitive issues is with organising and planning . You could say I'm fairly disorganised. Tasks needing a sequence of actions are problematic. I've yet to be put on a medication that really helps with this.
However in terms of thought disorder or disorganised speech the only things I can relate to are occasionally losing my train of thought or a slight tendency towards stilted speech.
It can be difficult at times to organise my thoughts.If I try to think too much then I can get anxious and overwhelmed .
I tend to lead a rather simple life- eat,drink,sleep,watch tv and internet(forums,check emails, check rss feeds and twitter for articles to post) . The checking rss feeds and twitter requires a narrow, single minded focus rather than sequential thinking hence why it is an easier thing for me to do.
