Children and adolescents

The diagnosis of PTSD was originally developed for adults who had suffered from a single event trauma, such as rape, or a traumatic experience during a war.[9] However, the situation for many children is quite different. Children can suffer chronic trauma such as maltreatment, family violence, and a disruption in attachment to their primary caregiver.[10] In many cases, it is the child's caregiver who caused the trauma.[9] The diagnosis of PTSD does not take into account how the developmental stages of children may affect their symptoms and how trauma can affect a child’s development.[9]

The term developmental trauma disorder (DTD) has also been suggested.[10] This developmental form of trauma places children at risk for developing psychiatric and medical disorders.[10] Bessel van der Kolk explains DTD as numerous encounters with interpersonal trauma such as physical assault, sexual assault, violence or death. It can also be characterized by subjective events like betrayal, defeat or shame.[11]

Repeated traumatization during childhood leads to symptoms that differ from those described for PTSD.[11] Cook and others describe symptoms and behavioural characteristics in seven domains:[12][13]

Attachment – "problems with relationship boundaries, lack of trust, social isolation, difficulty perceiving and responding to others' emotional states"
Biology – "sensory-motor developmental dysfunction, sensory-integration difficulties, somatization, and increased medical problems"
Affect or emotional regulation – "poor affect regulation, difficulty identifying and expressing emotions and internal states, and difficulties communicating needs, wants, and wishes"
Dissociation – "amnesia, depersonalization, discrete states of consciousness with discrete memories, affect, and functioning, and impaired memory for state-based events"
Behavioural control – "problems with impulse control, aggression, pathological self-soothing, and sleep problems"
Cognition – "difficulty regulating attention, problems with a variety of 'executive functions' such as planning, judgement, initiation, use of materials, and self-monitoring, difficulty processing new information, difficulty focusing and completing tasks, poor object constancy, problems with 'cause-effect' thinking, and language developmental problems such as a gap between receptive and expressive communication abilities."
Self-concept – "fragmented and disconnected autobiographical narrative, disturbed body image, low self-esteem, excessive shame, and negative internal working models of self".

AT: I have told by my psychiatrist and psychologist that C-PTSD is inclusive of these 7 domains, altogether already, including amnesnia and depersonalisation...etc. Please see it i in bold, that is why they told me that it does not have to be separately diagnosed.
