Social integration and brain chemistry approaches to treating PTSD

This NYT article (h/t Greg Downey on FB; check out his Neuroanthropology blog) lays out research on the effects of social conditions (isolation vs integration) on PTSD. Greg excerpted this quote: 

It turns out that most trauma victims — even survivors of combat, torture or concentration camps — rebound to live full, normal lives. That has given rise to a more nuanced view of trauma — less a poison than an infectious agent, a challenge that most people overcome but that may defeat those weakened by past traumas, genetics or other factors. Now, a significant body of work suggests that even this view is too narrow — that the environment just after the event, particularly other people’s responses, may be just as crucial as the event itself.

I thought this one about Nepalese ex-child soldiers provided a good concrete example: 

But in villages that readily and happily reintegrated them (usually via rituals or conventions specifically designed to do so), they experienced no more mental distress than did peers who had never gone to war. The lasting harm of being a child soldier, it seemed, arose not from the war but from social isolation and conflict afterward.

Contrast* the social integration approach to an individual pathology approach, using cognitive behavioral therapy and / or SSRIs to handle symptoms or beta-blockers to intervene in memory formation (another h/t to Greg Downey for this link). 

* Please note that I am saying "contrast" and not "oppose" as PTSD is a multiplicity rather than a unity, that is, there are multiple interactive and dynamic factors in multiple registers of "political phsyiology." (Thanks to Rebecca Todd on FB for reminding me of this.) The key for me is how to limn the multiplicity so that the dynamically interactive neurochemical AND social dimensions of our "body politic" can be thought and acted upon synergistically. (And note also that "social" here would have to include "political economy" since the way "meds" and "talk therapy" intersect includes Medicare, Medicaid, VA, and plain old insurance industry factors.)
