If personality disorder is no longer to be a diagnosis of exclusion it needs a conceptual framework that fits both the symptoms of the illness and the behavioural problems that constitute its current diagnostic criteria. In this article, we suggest that personality disorder is best understood as disorganisation of the capacity for affect regulation, mediated by early attachments. We present evidence for this argument based on both developmental and neurobiological research.
