Funny you should cite Bessel van der Kolk in the same paragraph as “the fragile medical biological paradigm of mental health”. He is totally committed to the neurobiological paradigm for PTSD and other forms of trauma, as well as all of psychiatry. Yes, he uses and promotes numerous forms of therapy, such as EMDR, IFS and psychodrama, but also the questionable neurofeedback. But most crucially, he sees neuroscientific explanations of PTSD (and other mental “disorders”) as definitive and, ultimately, the basis for diagnosis, prognosis and therapy. I’ve personally tried to pry him away from that extreme, unsupportable position, to no avail.
