Fiction writers struggle to accurately portray neurological consequences of head trauma without breaking character believability

Writers crafting realistic narratives face uncertainty about whether severe head trauma can authentically produce dissociative identity disorder or if they should use alternative explanations like memory suppression. They lack accessible, authoritative guidance on the medical accuracy of trauma-induced personality changes, forcing them to either guess, over-research, or compromise their story's credibility with readers who notice inaccuracies.
