I began a short story based on a dream, racing in a truck through mud. I was a younger man, 18 or so, with a friend driving. Ended in a crash. The problem is not thinking of a brain injury or problem from the crash, but a potential reversal of a previous mental issue...why do I need that? Because when I started writing the story, the voice I used (1st person) has been widely thought to be the voice of someone who is mentally handicapped. And I can see it, very simple lines of thought and interpretations of situations, not without clear insight, but with a voice so simple it makes the MC seem either many years younger or mentally handicapped. So...if I want to keep the unique voice, I need to fix him toward the end or explain it in some way...Anyone know of any potential long term (if untreated) cognitive block causing syndromes, diseases, can it happen with a brain injury and be reversed quickly? Should I just hang the sense of it and make it work? Thanks.
