Dr. Allan Schore discusses “Attachment trauma and the effects of neglect and abuse on the brain“.
The development of severe Psychopathologies occurs during right Brain development, during very early childhood. Attachment Trauma and Abandonment Trauma are all stored in the right hemisphere of the Brain, even before the left hemisphere starts to develop.
That is why Brain Scans of Narcissists, Borderlines and Psychopaths show differences from the general population. Because of Attachment Trauma and Abandonment Trauma, the brains of those with Severe Psychopathologies are unable to to wire themselves normally. It is not nature. It is nurture and the severe lack of nurture which plays a major role in creating those with severe Personality Disorders.
