Striking Discrepancy of Anomalous Body Experiences with Normal Interoceptive Accuracy in Depersonalization-Derealization Disorder
BACKGROUND Disembodiment is a core feature of depersonalization disorder (DPD). Given the narratives of DPD patients about their disembodiment and emotional numbing and neurobiological findings of an inhibition of insular activity, DPD may be considered as a mental disorder with specific impairments of interoceptive awareness and body perception. METHODS We investigated cardioceptive accuracy...
متن کاملDepersonalization: a selective impairment of self-awareness.
Depersonalization is characterised by a profound disruption of self-awareness mainly characterised by feelings of disembodiment and subjective emotional numbing. It has been proposed that depersonalization is caused by a fronto-limbic (particularly anterior insula) suppressive mechanism--presumably mediated via attention--which manifests subjectively as emotional numbing, and disables the proce...
متن کاملLong term effects of Gamma knife Radiosurgery for treatment of cerebral arteriovenous malformations
Abstract Background: The Gamma Knife Radiosurgery (GKR) is an established management option for Cerebral Ar-teriovenous Malformations (AVMS). Therapeutic benefits of radiosurgery for arteriovenous malformations are complete obliteration of nidus with minimal neurological deficit. Methods: Radiosurgery was performed between February 2003 and April 2010 at Kamraniye day clinic, Teh-ran, Iran, us...
متن کاملPsychophysiological investigations in depersonalization disorder and effects of electrodermal biofeedback.
Previous studies investigating depersonalization disorder (DPD) report a lower baseline skin conductance level (SCL) and attenuated skin conductance response (SCR) to emotive stimuli. We hypothesized that increasing physiological arousal levels via electrodermal biofeedback may ameliorate disembodiment and emotional numbing symptomatology. Real-time versus sham biofeedback yielded a significant...
متن کاملDeliberate and spontaneous sensations of disembodiment: capacity or flaw?
INTRODUCTION Hallucinations that involve shifts in the subjectively experienced location of the self, have been termed "out-of-body experiences" (OBEs). Early psychiatric accounts cast OBEs as a specific instance of depersonalisation and derealisation disorder (DPD-DR). However, during feelings of alienation and lack of body realism in DPD-DR the self is experienced within the physical body. De...
