Developmental Trauma Disorder is a little known phrase that is only now beginning to gain traction with health authorities. Why is it important? Sarah Naish, explains -  it is the right term to describe the behavioural characteristics displayed by children due to neglect and trauma or by those who experienced serious pre-birth problems. All too often, their symptoms are diagnosed as post traumatic stress disorder complex. But this is not the correct diagnosis and can lead to wrong assumptions by professionals that end up with the child being misdiagnosed.
