Question about dissociative disorder?

I am hoping there is some professional medical person out there who can help. I am trying to write a story. I am doing the whole “single workaholic person story where they get into some sort of accident, then wake up being married with a family, but not remembering them.” Only, I want to do it with a twist. I don’t remember the original, but Nicholas Cage did a version titled “the family man” only my character doesn’t try and kill themselves, and its not centered around Christmas.



In my story, it is learned at the end that this character has had an accident that injured her head, so she has amnesia, but of course she doesn’t know that. And no one tells her.



Problem is, I don’t know if this fits into what I am trying to write. At the end of the story my character learns (after getting into another minor head injury accident) that her single workaholic life was just a figment of her imagination, and the family %26amp; kids are real. Basically, the life she thought was real wasn’t, and the life she thought wasn’t real was her real life.



Would this be considered Dissociative amnesia, or something all together? Anyone who knows about amnesia and other head disorders please help. I hope I described my story well enough for you to get the picture.Question about dissociative disorder?
Traumatic Brain Injuries (TBIs) do not cause an 'alternate universe' to appear in anyone's head. Head wounds cause a DEFICIT of important skills, such as cognitive function. A second head injury only scrambles the picture. All of this damage is permanent. Research about all the GIs in Iraq coming home with TBIs. They are a mess and are unlikely to get any better. All they can be trained to do is cope and live with the damage. Your premise is highly unrealistic, and would make for bad television.Question about dissociative disorder?
That would be something different. Dissociative amnesia is when traumatic events are dissociated (forgetten). It only happens with trauma and it is a form of amnesia... it does not insert false memories... only removes the trauma. In the case of your story dissociative amnesia would be amnesia of the car accident... nothing more.
