So I'm working on a fictional story and I have a character that is severely abused, until it culminates with a severe beating that results in a severe concussion and knife stabbed into the skull. My character ends up with a dramatic change in personality. The character becomes easily distracted, with a tendency to drift off into daydreams and disjointed thoughts. This is due to a combination of thought disorders, most primarily derailment, distractible speech, palilalia, and tangentiality. This leads to difficulty speaking, making his phrases mixed up and disjointed. From the research I have, I was thinking severe concussion and knife entering from around the pterion and angled towards the frontal cortex. The tissue around the injury will become damaged due to a combination of lack of blood flow and hemorrhaging. The damage to the pre-frontal cortex will cause the Palilalia, the damage to the right hemisphere will cause the tengentiality. Possibly this character is one of the oddballs that has the Broca's area in the right hemisphere, which would add to the damage. I was also thinking about schizophrenia following a TBI, since brain trauma raises your risks of getting schizophrenia, but I don't really want that as it would muddy up the plot. But it's still an option. All of this is brought to you by two semesters of anatomy and some Google research, so how far off am I?
