I think somewhere between 4 and 8 years old is when a child can fully grasp the difference between 'real' and 'fiction'. Which is also why I'm with
@Chava, in terms of needing to create a separate diagnosis for developmental trauma. I don't think it plays by the same rules.
Sounds about right. I don't really buy the fictional part, because we know it's...fiction. But we also, ideally, shelter young children from violent programs (and why movies are rated). Media would affect them differently...doubtfully a case for trauma, but I don't know. "Developmental" often refers to those earliest years where brains and foundation of socialization is developed (fundamental wiring of lifelong patterns). Developmental trauma can happen in perfectly loving families...multiple surgeries, separations, shock trauma at that age, etc. But also obviously abuse and neglect. The symptoms end up very global, potentially looking like possibly up to ten other possible diagnosis (and some probably valid). But I like "complex" as separate to account for things like captivity, multiple trauma later childhood or adulthood...
I'd fit the sketched out definitions for developmental trauma (understood and described by trauma experts like Heller, Fisher, and Van Der Kolk)...quite close to inhibited form of reactive attachment disorder, loads of somatic issues, dissociative with certain triggers, lots of derealization shit, self-destructive, connect more with gadgets and ideas than humans (why I might seem a little Aspie but I'm not ASD). I was hit, had a door and chair broken against my back, and generally terrorized in middle childhood. But I think the earliest stuff (age 0-4 traumas) is still what I still deal with most painfully day to day. I was already starving, drinking, and cutting before assaulted as a teen...diagnosed PTSD after a suicide attempt in response to the assault. The therapist creeped me out and I never went back. My avoidance was really deep and I just kept starving for years. Now my therapist frames it all as "complex trauma", which makes enough sense. It accounts for all of it, and she understands there is a very early trauma component and what that looks like. My "avoidance" and "re-experiencing" are deep patterns but don't look quite like adult PTSD. If there was just PTSD and CPTSD (that could account for developmental or multiple traumas, or captivity), that's probably good enough...but still requiring therapists who understand how child development corresponds to the ages of traumas.
We are stuck with this mess in a good way...we are starting to recognize the deep and global impacts of trauma. But that doesn't mean we're figuring it out very quickly. There was support from a team of top trauma specialists compiling hundreds of profile, yet Van Der Kolk's "DTD" did not make it into the DSM. There was not, supposedly, enough clinical evidence. Van Der Kolk states that childhood trauma is "radically different" from trauma to fully formed adults. DTD would have encompassed the large range of symptoms for many children who go without treatment (later struggle in school, and a portion of traumatized children end up later incarcerated). Instead, the DSM V has what Van Der Kolk calls a "smorgasbord" of "diagnoses" associated with early-life trauma, including some new ones like "Disruptive Mood Regulation Disorder, Non-suicidal Self Injury, Intermittent Explosive Disorder, Dysregulated Social Engagement Disorder, and Disruptive Impulse Control Disorder" ("The Body Keeps the Score", p. 164). :sour::meh: WTF? Basically, these kids get labels as their symptoms, and treated with whack-a-mole behavioral and Special Education approaches (the emotional-behavioral disorder subset within American SpEd), versus being helped from a trauma-informed perspective.
In response to the DSM V, the director of the National Institute for Mental Health, Thomas Insel, announced that the NIMH could no longer support the DSM's "symptom-based diagnosis." (Van Der Kolk, p. 165)
So, that's where we're at with that...
