I've been reading here for a while, but I joined so I could post what has helped my cognition problems the most: Aricept. It's an alzheimer medicine. It's great stuff, and it has saved me on the cognition front.
I, too, had problems making my words flow. On occasion I would even have long pauses between sylables. Sometimes I had a "pseudo-stutter;" meaning that I would start a word, realize that I would not be able to enunciate the rest of the word, and then would just start over, planning ahead the full enunciation of the word.
I think of Aricept as my "word pill." (Generic is donepezil.)
I'm reading the boards and figuring out which supplements I should be using, diet modifications, etc.
But for signinficant cognition problems, Aricept can be a game-changer.
