My ability to talk is very variable. Sometimes it seems like the ability is completely gone.
But, when I cannot speak, I don't have the experience of having words ready in my head. I just cannot convert my sensory understanding of some idea into words at all.
I'm actually taking an antipsychotic which has helped my speech be more consistent. (My verbal fluency was measured at 11% - below the marker for adults with dementia...but mine has always been that way.)
