Psychiatrist Bessel van der Kolk explores his field’s long, complex, and stubborn history with trauma. Dr. van der Kolk explains how psychiatry as a whole avoided progress, often misdiagnosing trauma as hysteria or, in the case of shell-shocked soldiers, malingering. The experiences of abused women and children were more or less ignored for a century. They’re still being ignored in ways, he says. Psychiatry is still too focused on abstract diagnoses and not cognizant enough of the traumatic experiences that lead to them. His latest book “The Body Keeps the Score” was written to draw attention to how traumatic disorders can be avoided.
