[Pain processing in patients with borderline personality disorder, fibromyalgia, and post-traumatic stress disorder].
The authors review relevant experimental studies on pain perception and processing in psychiatric disorders with traumatic stress as an etiological factor. In borderline personality disorder, post-traumatic stress disorder, and fibromyalgia neurophysiological and neuropsychological patterns of pain processing appear to be different. Experimental studies in borderline patients show a desensitization of pain thresholds whereas patients with fibromyalgia show an opposite pattern, which could be explained by a central augmentation of pain processing. Furthermore, the authors outline methods to assess pain perception (peripheral and central) and describe the neurobiological mechanisms of pain processing, particularly the distinction between the sensory-discriminative lateral system and the affective-motivational medial system. Finally, suggestions for further research and implications for therapy are proposed.
