Cardiac modulation of startle is altered in depersonalization-/derealization disorder: Evidence for impaired brainstem representation of baro-afferen…

2016

Patients with depersonalization-/derealization disorder (DPD) show altered heartbeat-evoked brain potentials, which are considered psychophysiological indicators of cortical representation of visceral-afferent neural signals. The aim of the current investigation was to clarify whether the impaired CNS representation of visceral-afferent neural signals in DPD is restricted to the cortical level or is also present in sub-cortical structures. We used cardiac modulation of startle (CMS) to assess baro-afferent signal transmission at brainstem level in 22 DPD and 23 healthy control individuals. The CMS paradigm involved acoustic startle stimuli (105dB(A), 50ms) elicited 0, 100, 200, 300, 400 and…

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 (CA) of DPD patients (n = 24) as compared to healthy controls (n = 26) with two different heartbeat detection tasks (“Schandry heartbeat counting task” and “Whitehead heartbeat discrimination task”). Self-rated clearness of body perception was measured by questionnaire. Results Contrary to our hypothes…

Wie oft wird die Depersonalisations-Derealisationsstörung (ICD-10: F48.1) in der ambulanten Versorgung diagnostiziert?

2010

Zusammenfassung Fragestellung: Untersucht wird erstmalig, wie haufig die Depersonalisations-Derealisationsstorung (ICD-10: F48.1) in der Allgemeinbevolkerung unter Alltagsbedingungen diagnostiziert wird und mit welchen weiteren Krankheitsgruppen sie assoziiert ist. Methode: Die Untersuchungspopulation umfasst 1.567 Millionen Versicherte einer gesetzlichen Krankenkasse (Gmunder Ersatzkasse). Analysiert wird die Einjahrespravalenz der Diagnose F48.1 sowie deren Assoziation mit anderen ICD-10-Diagnosenschlusseln. Ergebnis: Es fand sich eine Einjahrespravalenz fur die Diagnose F48.1 von 0.007 %. Nach Adjustierung fur Alter, Geschlecht, Depression und Angst waren unter anderem folgende somatisch…
