There are such fields as social and affective neuroscience which have already contributed significantly to our understanding of pathology, e.g., breakdown of mirror neuron systems in autism, or why anxiety always feels like a loss of control at the level of conscious experience.  Psychobiological attachment research has significantly impacted on our understanding of why depressed, anxious caregivers add to the allostatic load of their infants/children, etc. and what kinds of experiences are required to epigenetically to reverse this.  I would recommend any of the following texts for an informed viewpoint.
