Abstract:Persistent somatoform pain disorder (PSPD) is a common and complex clinical disease and a subtype of somatoform disorder. Patients usually have repeated visits, uncertain treatment outcomes, and high levels of anxiety. The pathogenesis of PSPD is not yet clear, there are no specific drugs, and clinical treatment is mostly based on antidepressant drugs, antipsychotic drugs and other drug treatment, combined with psychotherapy[1]. In this paper, we review and summarize the recent research progress of PSPD in neurophysiological mechanisms, in order to provide reference for clarifying the pathogenesis of PSPD.
