An interest of mine at the moment is the idea of 'developmental trauma'. Practitioners and researchers are attempting to include developmental trauma in the latest version of the Diagnostic and Statistical Manual (DSM-5) of the American Psychiatric Association. I recently read a brilliant article about this by Mary Sykes Wylie which appeared in the Psychotherapy Networker as "The Long Shadow of Trauma". Wylie writes about the impact of early trauma on later life; but she also writes a fascinating piece about the importance of research in changing the minds of the medical establishment.
Developmental Trauma is the phrase used to describe a cluster of symptoms that result from early experiences of trauma, and in particular abuse and neglect. These experiences leave their mark on brain development (see, for example, this article in Science Daily or this one in New Scientist) and on the child's psychological, emotional, social and moral development. Indeed a child's ability to regulate their emotions and manage their behaviour will be impaired, leaving them vulnerable to alcohol and drug misuse, risk taking, violence, attachment problems and long-term health problems. In my current work as a counsellor I see the signs of developmental trauma; but it was as a probation worker and a youth justice worker, that I saw most clearly the negative impact of early neglect and abuse on the lives of individuals.
Adverse Childhood Experiences Study referred to in the The Long Shadow of Trauma article, this mammoth study is demonstrating the long-term impact of early trauma.
