Die der Generalisierung zugrunde liegenden psychologischen und biologischen Prozesse sind jedoch beim Menschen bisher nur wenig untersucht. Ziel dieser Arbeit war, anhand eines neu entwickelten experimentellen Paradigmas den Einfluss eines psychometrisch bestimmbaren angstspezifischen Faktors sowie der mit Furcht und Angst assoziierten Genotypen Stathmin1, COMT Val158Met und BDNF Val66Met auf die Furchtkonditionierung und Generalisierung konditionierter Furcht zu untersuchen und somit m{\"o}gliche Risikofaktoren f{\"u}r die Entstehung von Angsterkrankungen zu bestimmen. Hierf{\"u}r wurden N = 126 gesunde Versuchspersonen (n = 69 weiblich; mittleres Alter M = 23.05, SD = 3.82) f{\"u}r die genannten Polymorphismen genotypisiert und zu {\"a}ngstlichen und affektiven Symptomen befragt. In einer Akquisitionsphase wurden den Probanden zwei neutrale weibliche Gesichter pr{\"a}sentiert (CS), von denen eines mit einem Schrei sowie einem {\"a}ngstlichen Gesichtsausdruck (UCS) gepaart wurde. Der sich anschließende Generalisierungstest erfolgte anhand von vier Gesichtern, die in der {\"A}hnlichkeit zwischen den beiden CS schrittweise {\"u}bergingen. Die Furchtreaktion wurde {\"u}ber die Bewertung von Valenz, Arousal und Kontingenzerwartung sowie {\"u}ber die Hautleitf{\"a}higkeitsreaktion (SCR) erfasst. Die Analyse der Frageb{\"o}gen anhand einer Hauptachsenanalyse und anhand von Strukturgleichungsmodellen erbrachte eine zweifaktorielle L{\"o}sung, die die Konstrukte Depression und Angst abbildete. Nur der Faktor Angst war mit einer ver{\"a}nderten Furchtkonditionierung und Furchtgeneralisierung assoziiert: Hoch {\"A}ngstliche zeigten eine st{\"a}rkere konditionierte Furchtreaktion (Arousal) und wiesen eine st{\"a}rkere Generalisierung der Valenzeinsch{\"a}tzung und Kontingenzerwartung auf. F{\"u}r den Stathmin1 Genotyp ergaben sich geschlechtsspezifische Effekte. Bei den m{\"a}nnlichen Versuchspersonen zeigte sich in Folge der Akquisition ein st{\"a}rkerer Abfall der Valenz f{\"u}r den CS+ in der Gruppe der Stathmin1 T Alleltr{\"a}ger, die ebenfalls eine st{\"a}rkere Generalisierung der Furchtreaktion, abgebildet in allen verbalen Maßen, aufwiesen. Ein gegenteiliger Befund ergab sich f{\"u}r die Gruppe der Frauen, insofern eine mit dem Stathmin1 C Allel assoziierte h{\"o}here Generalisierung der Valenz, des Arousals und der Kontingenzerwartung festgestellt werden konnte. F{\"u}r den COMT Val158Met Genotyp ergaben sich keine Einfl{\"u}sse auf die Akquisition der konditionierten Furcht. F{\"u}r Tr{\"a}ger des COMT 158Val Allels zeigte sich jedoch eine st{\"a}rkere Generalisierung der Valenz und der Kontingenzerwartung. Auch f{\"u}r den BDNF Val66Met Genotyp konnte keine Ver{\"a}nderung der Furchtakquisition beobachtet werden. Es ergaben sich jedoch Hinweise auf eine erh{\"o}hte Generalisierung der Kontingenzerwartung in der Gruppe der BDNF 66Val Homozygoten. F{\"u}r keinen der beschriebenen Faktoren konnte ein Einfluss auf die Furchtkonditionierung oder deren Generalisierung anhand der SCR abgebildet werden. Unsere Ergebnisse weisen auf einen psychometrisch erfassbaren Faktor und genetische Einfl{\"u}sse hin, die {\"u}ber den Prozess einer st{\"a}rkeren Generalisierung der konditionierten Furcht das Risiko f{\"u}r die Entstehung von Angsterkrankungen erh{\"o}hen k{\"o}nnen. Jedoch sollten die Befunde in gr{\"o}ßeren Stichproben repliziert werden. Neben der fr{\"u}hzeitigen Identifikation von Risikofaktoren sollten in zuk{\"u}nftigen Studien dar{\"u}ber hinaus wirksame Maßnahmen zur Pr{\"a}vention und Intervention entwickelt werden, um diesem Risiko entgegen zu wirken.}, subject = {Konditionierung}, language = {de} } @article{BonnSchmittLeschetal.2013, author = {Bonn, M. and Schmitt, A. and Lesch, K.-P. and Van Bockstaele, E.

The lateral and basolateral amygdaloid nuclei receive a dense serotonergic innervation in all species studied to date. We investigated interrelations between serotonergic afferents and neuropeptide Y (NPY)-producing neurons, which are a subpopulation of inhibitory interneurons in the rat lateral and basolateral nuclei with particularly strong anxiolytic properties. Dual light microscopic immunolabeling showed numerous appositions of serotonergic afferents on NPY-immunoreactive somata. Using electron microscopy, direct membrane appositions and synaptic contacts between serotonin-containing axon terminals and NPY-immunoreactive cellular profiles were unequivocally established. Double in situ hybridization documented that more than 50 \%, and about 30-40 \% of NPY mRNA-producing neurons, co-expressed inhibitory 5-HT1A and excitatory 5-HT2C mRNA receptor subtype mRNA, respectively, in both nuclei with no gender differences. Triple in situ hybridization showed that individual NPY mRNA-producing interneurons co-express both 5-HT1A and 5-HT2C mRNAs. Co-expression of NPY and 5-HT3 mRNA was not observed. The results demonstrate that serotonergic afferents provide substantial innervation of NPY-producing neurons in the rat lateral and basolateral amygdaloid nuclei. Studies of serotonin receptor subtype co-expression indicate a differential impact of the serotonergic innervation on this small, but important, population of anxiolytic interneurons, and provide the basis for future studies of the circuitry underlying serotonergic modulation of emotional stimulus processing in the amygdala.}, language = {en} } @article{BuffBrinkmannBruchmannetal.2017, author = {Buff, Christine and Brinkmann, Leonie and Bruchmann, Maximilian and Becker, Michael P.I. and Tupak, Sara and Herrmann, Martin J. and Straube, Thomas}, title = {Activity alterations in the bed nucleus of the stria terminalis and amygdala during threat anticipation in generalized anxiety disorder}, series = {Social Cognitive and Affective Neuroscience}, volume = {12}, journal = {Social Cognitive and Affective Neuroscience}, number = {11}, doi = {10.1093/scan/nsx103}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-173298}, pages = {1766-1774}, year = {2017}, abstract = {Sustained anticipatory anxiety is central to Generalized Anxiety Disorder (GAD). During anticipatory anxiety, phasic threat responding appears to be mediated by the amygdala, while sustained threat responding seems related to the bed nucleus of the stria terminalis (BNST). Although sustained anticipatory anxiety in GAD patients was proposed to be associated with BNST activity alterations, firm evidence is lacking. We aimed to explore temporal characteristics of BNST and amygdala activity during threat anticipation in GAD patients. Nineteen GAD patients and nineteen healthy controls (HC) underwent functional magnetic resonance imaging (fMRI) during a temporally unpredictable threat anticipation paradigm. We defined phasic and a systematic variation of sustained response models for blood oxygen level-dependent responses during threat anticipation, to disentangle temporally dissociable involvement of the BNST and the amygdala. GAD patients relative to HC responded with increased phasic amygdala activity to onset of threat anticipation and with elevated sustained BNST activity that was delayed relative to the onset of threat anticipation. Both the amygdala and the BNST displayed altered responses during threat anticipation in GAD patients, albeit with different time courses. The results for the BNST activation hint towards its role in sustained threat responding, and contribute to a deeper understanding of pathological sustained anticipatory anxiety in GAD.}, language = {en} } @phdthesis{Calame2004, author = {Calame, Silke}, title = {Zusammenhang von Angst mit dem Schweregrad der Anorexia nervosa - Komorbidit{\"a}t am Beispiel einer klinischen Studie}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-13830}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2004}, abstract = {In der Literatur wird eine hohe Komorbidit{\"a}t zwischen Anorexia nervosa und Angstst{\"o}rungen beschrieben.

ICD-Patienten berichten jedoch {\"u}berdurchschnittlich h{\"a}ufig von {\"A}ngsten und einer eingeschr{\"a}nkten Lebensqualit{\"a}t. Ziel: In dieser Studie wurde ein speziell f{\"u}r ICD-Patienten entwickeltes Pr{\"a}ventionsprogramm gegen {\"A}ngste evaluiert. Dieses beinhaltet zum einen gedruckte Informationen dar{\"u}ber, wie {\"A}ngste fr{\"u}hzeitig erkannt werden k{\"o}nnen und welche Hilfsm{\"o}glichkeiten es gibt. Zum anderen bietet es Patienten die M{\"o}glichkeit, einem telefonischen Ansprechpartner (Dipl.-Psych.) Fragen zum ICD zu stellen und {\"u}ber psychische Belastungen und M{\"o}glichkeiten zu deren Linderung zu sprechen. Gleichzeitig wurde in dieser Studie die M{\"o}glichkeit untersucht, die {\"A}ngste der Patienten, die nach der Anpassungsphase entstehen, vorherzusagen. Methoden: 119 ICD-Patienten f{\"u}llten zu zwei Zeitpunkten (30 Tage nach der Implantation und 6 Monate sp{\"a}ter) psychometrische Frageb{\"o}gen zur Erfassung von {\"A}ngsten aus (z.B. Hospital Anxiety and Depression Scale). Nach der ersten Messung wurden die Patienten teilrandomisiert (Schichtung nach Indikation, Alter und Geschlecht) zwei Gruppen zugewiesen. Eine Gruppe nahm zwischen den beiden Messzeitpunkten zus{\"a}tzlich zur medizinischen Betreuung am beschriebenen Pr{\"a}ventionsprogramm teil, die andere Gruppe erhielt keine zus{\"a}tzliche Betreuung. Zur Pr{\"a}diktion der sp{\"a}teren Angstwerte wurden Regressionsanalysen durchgef{\"u}hrt. Als Pr{\"a}diktoren dienten die Charakteristiken der Patienten, die zum ersten Messzeitpunkt erhoben worden waren. Kriterium war die Angst der Patienten zum zweiten Messzeitpunkt. Ergebnisse: Das Pr{\"a}ventionsprogramm wurde von allen ICD-Patienten gut angenommen und von vielen Patienten (75\%) als hilfreich beurteilt. Entgegen der Erwartungen unterschieden sich die beiden Gruppen hinsichtlich der Angstentwicklung jedoch nicht voneinander. Die differenzierte Analyse zeigte, dass die Wirkung des Pr{\"a}ventionsprogramms auf die Angst der Patienten von deren Alter abhing (p = 0,01). Bei den j{\"u}ngeren ICD-Patienten (30-64 Jahre) ließ sich durch das Programm ein Anstieg der {\"A}ngste im Halbjahr nach der Implantation verhindern. Die subjektiv berichteten {\"A}ngste der behandelten Gruppe der {\"a}lteren Patienten (65-75 Jahre) entwickelten sich jedoch ung{\"u}nstiger als die der Kontrollgruppe. J{\"u}ngere Patienten berichteten nach der Implantation generell {\"u}ber mehr Einschr{\"a}nkungen durch den ICD und f{\"u}hlten sich weniger gut durch ihn gesch{\"u}tzt als {\"a}ltere Patienten. In der Kontrollgruppe war die Vorhersage der Angst zum zweiten Messzeitpunkt am Besten durch die Einstellung der Patienten zum ICD m{\"o}glich. In der Experimentalgruppe war die Angstsensitivit{\"a}t der Patienten der beste Pr{\"a}diktor. Schlussfolgerung: J{\"u}ngere Patienten profitierten vom auf Informationen und Gespr{\"a}chen basierenden Pr{\"a}ventionsprogramm. {\"A}ltere Patienten dagegen berichteten subjektiv {\"u}ber mehr {\"A}ngste, obwohl sie das Pr{\"a}ventionsprogramm auch als hilfreich erachteten.

This technology, with its unique ability to simulate complex, real situations and contexts, offers researchers unprecedented opportunities to investigate human behavior in well controlled designs in the laboratory. One important application of VR is the investigation of pathological processes in mental disorders, especially anxiety disorders. Research on the processes underlying threat perception, fear, and exposure therapy has shed light on more general aspects of the relation between perception and emotion. Being by its nature virtual, i.e., simulation of reality, VR strongly relies on the adequate selection of specific perceptual cues to activate emotions. Emotional experiences in turn are related to presence, another important concept in VR, which describes the user's sense of being in a VR environment. This paper summarizes current research into perception of fear cues, emotion, and presence, aiming at the identification of the most relevant aspects of emotional experience in VR and their mutual relations. A special focus lies on a series of recent experiments designed to test the relative contribution of perception and conceptual information on fear in VR. This strand of research capitalizes on the dissociation between perception (bottom up input) and conceptual information (top-down input) that is possible in VR. Further, we review the factors that have so far been recognized to influence presence, with emotions (e.g., fear) being the most relevant in the context of clinical psychology. Recent research has highlighted the mutual influence of presence and fear in VR, but has also traced the limits of our current understanding of this relationship. In this paper, the crucial role of perception on eliciting emotional reactions is highlighted, and the role of arousal as a basic dimension of emotional experience is discussed. An interoceptive attribution model of presence is suggested as a first step toward an integrative framework for emotion research in VR.

Methods/Design: In this multicenter, prospective, observational study 3,950 patients with HF are recruited by general practices in Germany. The patients fill out questionnaires at baseline and 12-month follow-up. At baseline the GPs are interviewed regarding the somatic and psychological comorbidities of their patients. During the follow-up assessment, data on hospitalization and mortality are provided by the general practice. Based on baseline data, the patients are allocated into three observation groups: HF patients with depression and/or anxiety recognized by their GP (P+/+), those with depression and/or anxiety not recognized (P+/-) and patients without depression and/or anxiety (P-/-). We will perform multivariate regression models to investigate the influence of the recognition of depression and/or anxiety on quality of life at 12 month follow-up, as well as its influences on the prognosis (hospital admission, mortality). Discussion: We will display the frequency of GP-acknowledged depression and anxiety and the frequency of installed therapeutic strategies. We will also describe the frequency of depression and anxiety missed by the GP and the resulting treatment gap. Effects of correctly acknowledged and missed depression/anxiety on outcome, also in comparison to the outcome of subjects without depression/anxiety will be addressed.

Among patients with prostate cancer (PCa), findings on depression and anxiety are limited. Methods We analyzed data of PCa patients selected from a German multi-center study. Depression and anxiety were assessed with the PHQ-9 and the GAD-7 (cut-off ≥7). We provided physical symptom burden, calculated absolute and relative risk (AR and RR) of depression and anxiety across patient subsets and between patients and the general population (GP) and tested age as a moderator within the relationship of disease-specific symptoms with depression and anxiety. Results Among 636 participants, the majority reported disease-specific problems (sexuality: 60\%; urination: 52\%). AR for depression and anxiety was 23\% and 22\%, respectively. Significant RR were small, with higher risks of distress in patients who are younger (eg, RR\(_{depression}\) = 1.15; 95\%-CI: 1.06-1.26), treated with chemotherapy (RR\(_{depression}\)n = 1.46; 95\%-CI: 1.09-1.96) or having metastases (RR\(_{depression}\) = 1.30; 95\%-CI: 1.02-1.65).

However, it is unclear whether CHF causes depression. Thus, we investigated whether mice develop anxiety- and depression-like behavior after induction of ischemic CHF by myocardial infarction (MI). Methods and Results: In order to assess depression-like behavior, anhedonia was investigated by repeatedly testing sucrose preference for 8 weeks after coronary artery ligation or sham operation. Mice with large MI and increased left ventricular dimensions on echocardiography (termed CHF mice) showed reduced preference for sucrose, indicating depression-like behavior. 6 weeks after MI, mice were tested for exploratory activity, anxiety-like behavior and cognitive function using the elevated plus maze (EPM), light-dark box (LDB), open field (OF), and object recognition (OR) tests. In the EPM and OF, CHF mice exhibited diminished exploratory behavior and motivation despite similar movement capability. In the OR, CHF mice had reduced preference for novelty and impaired short-term memory. On histology, CHF mice had unaltered overall cerebral morphology. However, analysis of gene expression by RNA-sequencing in prefrontal cortical, hippocampal, and left ventricular tissue revealed changes in genes related to inflammation and cofactors of neuronal signal transduction in CHF mice, with Nr4a1 being dysregulated both in prefrontal cortex and myocardium after MI. Conclusions: After induction of ischemic CHF, mice exhibited anhedonic behavior, decreased exploratory activity and interest in novelty, and cognitive impairment.

Welchen Einfluss haben medizinische bzw. klinische Variablen auf die emotionale Befindlichkeit bei Brustkrebspatientinnen? Gibt es Zusammenh{\"a}nge zwischen bestimmten anamnestischen Faktoren und krebsspezifischer Angst bei gesunden Frauen aus Risikofamilien? Bestehen Zusammenh{\"a}nge zwischen soziodemographischen Variablen und der emotionalen Befindlichkeit? Im Zeitraum von 1997 bis 1999 wurden im „Interdisziplin{\"a}ren Zentrum f{\"u}r famili{\"a}ren Brustkrebs" (Humangenetik, Gyn{\"a}kologie, Psychoonkologie) in W{\"u}rzburg 179 Ratsuchende im Alter zwischen 13 und 71 Jahren (M=42, s=12) beraten. Davon waren 72 Personen anamnestisch an Brust- oder Eierstockkrebs erkrankt, 107 Personen waren gesunde Angeh{\"o}rige aus Hochrisikofamilien. Das Alter der Erkrankten lag durchschnittlich h{\"o}her. Das Patientenklientel setzte sich zu 95,5\% aus weiblichen Teilnehmerinnen zusammen. Die Mehrzahl der Probanden war zum Untersuchungszeitpunkt verheiratet oder lebte in einer festen Partnerschaft. Die Erhebung s{\"a}mtlicher Daten erfolgte vor der Erstberatung zum Zeitpunkt der Inanspruchnahme der Tumorrisikosprechstunde. Neben der Erfassung medizinischer Daten anhand eines gyn{\"a}kologischen und biomedizinischen Erhebungsbogens wurden die Studienteilnehmer gebeten, einen umfassenden Fragenkatalog zu beantworten. F{\"u}r die vorliegende Arbeit wurden die Variablenbereiche Risikowahrnehmung und krebsspezifische Angst, seelisches Befinden sowie einige soziodemographische Daten erfasst und in die Untersuchung einbezogen. Die Studie wurde als kontrollierte Querschnittsuntersuchung konzipiert, um die emotionale Befindlichkeit zum Zeitpunkt der klinischen Vorstellung zu erfassen. Hinsichtlich des psychologisch-orientierten Fragebogenteils kam die deutsche Version der Hospital Anxiety and Depression Scale (HADS) von Herrmann et al. (1995) zum Einsatz. Die Ergebnisse hinsichtlich der zentralen Frage nach der Auspr{\"a}gung der psychologischen Merkmale Angst, Depressivit{\"a}t und krebsspezifischer Erkrankungsfurcht zeigten, dass sowohl Angst- als auch Depressivit{\"a}tswerte im Vergleich zu einer gesunden Kontrollgruppe durchschnittlich h{\"o}her lagen. Ebenso finden sich in unserer Studie mehr Personen mit klinisch auff{\"a}lligen Werten. Im Vergleich der beiden Subgruppen (Erkrankte vs. Gesunde) untereinander ergab sich hinsichtlich der psychosozialen Variablen kein signifikanter Unterschied, ebenso wenig ein Zusammenhang zwischen Risikostatus (definiert durch die H{\"a}ufigkeitsangabe aller erkrankten Angeh{\"o}rigen innerhalb einer Familie) und emotionaler Befindlichkeit. Bei den Brustkrebspatientinnen zeigte sich, dass das Erkrankungsstadium sowie die Art der Therapie keinen Effekt auf Angst, Depressivit{\"a}t und krebsspezifische Angst haben. Betroffene, deren Erstdiagnose l{\"a}nger als 5 Jahre zur{\"u}cklag, scheinen allerdings signifikant weniger krebsspezifisch {\"a}ngstlich zu sein als diejenigen, die in den letzten 5 Jahren ihre Diagnose erfahren hatten.

While anxiety is the cardinal symptom in disorders such as panic disorder, co-morbid anxious behavior can occur in a variety of diseases. Stiff person syndrome (SPS) is a CNS disorder characterized by increased muscle tone and prominent agoraphobia and anxiety. Most patients have high-titer antibodies against glutamate decarboxylase (GAD) 65. The pathogenic role of these autoantibodies is unclear. Methodology/Principal Findings: We re-investigated a 53 year old woman with SPS and profound anxiety for GABA-A receptor binding in the amygdala with (11) C-flumazenil PET scan and studied the potential pathogenic role of purified IgG from her plasma filtrates containing high-titer antibodies against GAD 65. We passively transferred the IgG fraction intrathecally into rats and analyzed the effects using behavioral and in vivo electrophysiological methods. In cell culture, we measured the effect of patient IgG on GABA release from hippocampal neurons. Repetitive intrathecal application of purified patient IgG in rats resulted in an anxious phenotype resembling the core symptoms of the patient. Patient IgG selectively bound to rat amygdala, hippocampus, and frontal cortical areas. In cultured rat hippocampal neurons, patient IgG inhibited GABA release. In line with these experimental results, the GABA-A receptor binding potential was reduced in the patient's amygdala/hippocampus complex. No motor abnormalities were found in recipient rats. Conclusion/Significance: The observations in rats after passive transfer lead us to propose that anxiety-like behavior can be induced in rats by passive transfer of IgG from a SPS patient positive for anti-GAD 65 antibodies. Anxiety, in this case, thus may be an antibody-mediated phenomenon with consecutive disturbance of GABAergic signaling in the amygdala region.}, language = {en} } @phdthesis{GlotzbachSchoon2013, author = {Glotzbach-Schoon, Evelyn}, title = {Contextual fear conditioning in humans: The return of contextual anxiety and the influence of genetic polymorphisms}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-87955}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2013}, abstract = {Als Angst bezeichnet man einen nicht auf spezifische Objekte gerichteten l{\"a}nger anhaltenden zukunfts-orientierten Zustand der Besorgnis. Diese ist kennzeichnend f{\"u}r Angstst{\"o}rungen wie Panikst{\"o}rung, generalisierte Angstst{\"o}rung und Posttraumatische Belastungsst{\"o}rung (PTBS). Experimentell kann Angst durch kontextuelle Furchtkonditionierung ausgel{\"o}st werden. Bei dieser Art der Konditionierung werden aversive Ereignisse als unvorhersehbar erlebt, wodurch der gesamte Kontext mit der Gefahr assoziiert wird. Diese Arbeit hat zum Ziel, Mechanismen der Entstehung und Aufrechterhaltung von Kontextangst zu untersuchen. Dies sind zum einem erleichterte Akquisition von Kontextkonditionierungen und deren fehlerhafte Extinktion. Hier ist vor allem die Fragestellung relevant, wie dies durch genetische Varianten moduliert wird (Studie 1). Zum anderen soll die Wiederkehr der Angst nach der Extinktion mit einem neuen Reinstatement-Paradigma untersucht werden (Studie 2). Zur Untersuchung dieser Forschungsfragen wurden zwei kontextuelle Furchtkonditionierungsstudien in virtueller Realit{\"a}t (VR) durchgef{\"u}hrt. W{\"a}hrend der Akquisition wurden leicht schmerzhafte elektrische Reize (unkonditionierter Stimulus, US) unvorhersehbar pr{\"a}sentiert, w{\"a}hrend die Probanden in einem virtuellen B{\"u}roraum waren. Dadurch wurde dieser Raum zum Angstkontext (CXT+). Ein zweiter B{\"u}roraum wurde nie mit dem US gepaart, deshalb wurde dieser Raum zum Sicherheitskontext (CXT-). Die Extinktion, in der die Kontexte ohne US pr{\"a}sentiert wurden, fand 24 h sp{\"a}ter statt, und ein Test zum Abruf der Extinktion bzw. zur Wiederkehr der Angst nochmals 24 h sp{\"a}ter. In beiden Studien wurde die Angst auf drei verschiedenen Ebenen gemessen: Verhalten (angstpotenzierter Schreckreflex), Physiologie (tonische Hautleitf{\"a}higkeit), und verbale Ebene (explizite Ratings). Die Probanden f{\"u}r Studie 1 wurden anhand der 5-HTTLPR (S+ Risikoallel vs. LL nicht-Risikoallel) und NPSR1 rs324981 (T+ Risikoallel vs. AA nicht-Risikoallel) Polymorphismen stratifiziert, sodass vier kombinierte Genotyp Gruppen (S+/T+, S+/LL, LL/T+ und LL/AA) mit je 20 Probanden vorlagen. Es zeigte sich, dass der angstpotenzierte Schreckreflex durch die Interaktion zwischen beiden genetischen Polymorphismen moduliert wurde. Nur Tr{\"a}ger beider Risikoallele (S+ Tr{\"a}ger des 5-HTTLPR und T+ Tr{\"a}ger des NPSR1 Polymorphismus) zeigten einen h{\"o}heren Schreckreflex im CXT+ als im CXT- w{\"a}hrend der Akquisition. Der Abruf der Extinktion an Tag 3, gemessen anhand des Schreckreflexes, wurde allerdings nicht durch die Genotypen moduliert. Interessanterweise zeigte sich auf dem expliziten Angstlevel (Valenz- und Angstratings) nur ein Einfluss des NPSR1 Polymorphismus, und zwar bewerteten die nicht-Risikoallel Tr{\"a}ger (AA) den CXT+ mit negativerer Valenz und h{\"o}herer Angst im Vergleich zum CXT-; die Risikoallel Tr{\"a}ger (T+) taten dies nicht. In der zweiten Studie wurde fast das gleiche Paradigma benutzt wie in der ersten Studie mit der Ausnahme, dass eine Versuchsgruppe (Reinstatementgruppe) den US noch einmal am Anfang des dritten Untersuchungstages vor der Pr{\"a}sentation von CXT+ und CXT- appliziert bekam. Die zweite Versuchsgruppe (Kontrollgruppe) erhielt keinen US, sondern wurde direkt durch CXT+ und CXT- gef{\"u}hrt. Es zeigte sich, dass nur in der Reinstatementgruppe die Angst auf impliziter und expliziter Ebene wiederkehrte, d.h. die Probanden zeigten einen h{\"o}heren Schreckreflex und h{\"o}here Angstratings auf den CXT+ im Vergleich zum CXT-. Wichtig war vor allem, dass die Wiederkehr der Angst in der Reinstatementgruppe mit der Ver{\"a}nderung der Zustandsangst und der Stimmung (von der Extinktion zum Test) korrelierte. D.h. je gr{\"o}ßer die Angst und je negativer die Stimmung wurden, desto h{\"o}her war die Wiederkehr der Angst. Zusammengefasst belegt Studie 1, dass erleichterte kontextuelle Furchtkonditionierung auf impliziter Ebene (Schreckreflex) ein Endoph{\"a}notyp f{\"u}r Angstst{\"o}rungen sein k{\"o}nnte, was zu unserem Verst{\"a}ndnis der {\"A}tiologie von Angstst{\"o}rungen beitragen k{\"o}nnte.

Although there has been significant progress in the understanding of neurobiological underpinnings of threat-related behaviors and anxiety, little progress was made with regard to new or improved treatments for mental disorders. A possible reason for this lack of success is the unknown predictive and cross-species translational validity of animal models used in preclinical studies. Re-translational approaches, therefore, seek to establish cross-species translational validity by identifying behavioral operations shared across species. To this end, we implemented a human open field test in virtual reality and measured behavioral indices derived from animal studies in three experiments (N=31, N=30, and N=80). In addition, we investigated the associations between anxious traits and such behaviors. Results indicated a strong similarity in behavior across species, i.e., participants in our study-like rodents in animal studies-preferred to stay in the outer region of the open field, as indexed by multiple behavioral parameters. However, correlational analyses did not clearly indicate that these behaviors were a function of anxious traits of participants. We conclude that the realized virtual open field test is able to elicit thigmotaxis and thus demonstrates cross-species validity of this aspect of the test. Modulatory effects of anxiety on human open field behavior should be examined further by incorporating possible threats in the virtual scenario and/or by examining participants with higher anxiety levels or anxiety disorder patients.}, language = {en} } @article{GromerMadeiraGastetal.2018, author = {Gromer, Daniel and Madeira, Oct{\´a}via and Gast, Philipp and Nehfischer, Markus and Jost, Michael and M{\"u}ller, Mathias and M{\"u}hlberger, Andreas and Pauli, Paul}, title = {Height Simulation in a Virtual Reality CAVE System: Validity of Fear Responses and Effects of an Immersion Manipulation}, series = {Frontiers in Human Neuroscience}, volume = {12}, journal = {Frontiers in Human Neuroscience}, number = {372}, issn = {1662-5161}, doi = {10.3389/fnhum.2018.00372}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-196113}, year = {2018}, abstract = {Acrophobia is characterized by intense fear in height situations. Virtual reality (VR) can be used to trigger such phobic fear, and VR exposure therapy (VRET) has proven effective for treatment of phobias, although it remains important to further elucidate factors that modulate and mediate the fear responses triggered in VR. The present study assessed verbal and behavioral fear responses triggered by a height simulation in a 5-sided cave automatic virtual environment (CAVE) with visual and acoustic simulation and further investigated how fear responses are modulated by immersion, i.e., an additional wind simulation, and presence, i.e., the feeling to be present in the VE. Results revealed a high validity for the CAVE and VE in provoking height related self-reported fear and avoidance behavior in accordance with a trait measure of acrophobic fear. Increasing immersion significantly increased fear responses in high height anxious (HHA) participants, but did not affect presence. Nevertheless, presence was found to be an important predictor of fear responses. We conclude that a CAVE system can be used to elicit valid fear responses, which might be further enhanced by immersion manipulations independent from presence.

These factors may be particularly relevant in contexts requiring social distancing, e.g., during the COVID-19 pandemic or in states of immunodeficiency. We present the Loneliness and Isolation during Social Distancing (LISD) Scale. Extending existing measures, the LISD scale measures both state and trait aspects of loneliness and isolation, including indicators of social connectedness and support. In addition, it reliably predicts individual differences in anxiety and depression. Data were collected online from two independent samples in a social distancing context (the COVID-19 pandemic). Factorial validation was based on exploratory factor analysis (EFA; Sample 1, N = 244) and confirmatory factor analysis (CFA; Sample 2, N = 304). Multiple regression analyses were used to assess how the LISD scale predicts state anxiety and depression. The LISD scale showed satisfactory fit in both samples. Its two state factors indicate being lonely and isolated as well as connected and supported, while its three trait factors reflect general loneliness and isolation, sociability and sense of belonging, and social closeness and support. Our results imply strong predictive power of the LISD scale for state anxiety and depression, explaining 33 and 51\% of variance, respectively. Anxiety and depression scores were particularly predicted by low dispositional sociability and sense of belonging and by currently being more lonely and isolated. In turn, being lonely and isolated was related to being less connected and supported (state) as well as having lower social closeness and support in general (trait). We provide a novel scale which distinguishes between acute and general dimensions of loneliness and social isolation while also predicting mental health.

Objective Here, we investigated the effect of constitutively impaired 5-HT synthesis on behavioral and neuroendocrine responses to unpredictable chronic mild stress (CMS) using a mouse model of brain 5-HT deficiency resulting from targeted inactivation of the tryptophan hydroxylase-2 (Tph2) gene. Results Locomotor activity and anxiety- and depression-like behavior as well as conditioned fear responses were differentially affected by Tph2 genotype, sex, and CMS. Tph2 null mutants (Tph2\(^{-/-}\)) displayed increased general metabolism, marginally reduced anxiety- and depression-like behavior but strikingly increased conditioned fear responses. Behavioral modifications were associated with sex-specific hypothalamic-pituitary-adrenocortical (HPA) system alterations as indicated by plasma corticosterone and fecal corticosterone metabolite concentrations. Tph2\(^{-/-}\) males displayed increased impulsivity and high aggressiveness. Tph2\(^{-/-}\) females displayed greater emotional reactivity to aversive conditions as reflected by changes in behaviors at baseline including increased freezing and decreased locomotion in novel environments. However, both Tph2\(^{-/-}\) male and female mice were resilient to CMS-induced hyperlocomotion, while CMS intensified conditioned fear responses in a GxE-dependent manner.

Stimuli evaluated as being stressful actuate a number of physiological processes as an immediate stress response. Variation in the serotonin transporter gene has been associated with increased anxiety- and depression-like behavior, altered stress reactivity and adaptation, and pathophysiology of stress-related disorders. In this study the instant reactions to an acute stressor were measured in a serotonin transporter knockout mouse model. Mice lacking the serotonin transporter were verified to be more anxious than their wild-type conspecifics. Genome-wide gene expression changes in the amygdala were measured after the mice were subjected to control condition or to an acute stressor of one minute exposure to water. The dissection of amygdalae and stabilization of RNA was conducted within nine minutes after the onset of the stressor. This extremely short protocol allowed for analysis of first wave primary response genes, typically induced within five to ten minutes of stimulation, and was performed using Affymetrix GeneChip Mouse Gene 1.0 ST Arrays. RNA profiling revealed a largely new set of differentially expressed primary response genes between the conditions acute stress and control that differed distinctly between wild-type and knockout mice. Consequently, functional categorization and pathway analysis indicated genes related to neuroplasticity and adaptation in wild-types whereas knockouts were characterized by impaired plasticity and genes more related to chronic stress and pathophysiology. Our study therefore disclosed different coping styles dependent on serotonin transporter genotype even directly after the onset of stress and accentuates the role of the serotonergic system in processing stressors and threat in the amygdala.

Recent negative life events (RLE), childhood adversity (CHA), lifetime depression, Brief Symptoms Inventory (BSI) depression and anxiety scores were determined in each subject. Besides traditional statistical analysis we calculated Bayesian effect strength and relevance of 5-HTTLPR genotypes in specified models. Results The short (s) low expressing allele showed association with increased risk of depression related phenotypes, but all nominally significant effects would turn to non-significant after correction for multiple testing in the traditional analysis. Bayesian effect strength and relevance analysis, however, confirmed the role of 5-HTTLPR. Regarding current (BSI) and lifetime depression 5-HTTLPR-by-RLE interactions were confirmed. Main effect, with other words direct association, was supported with BSI anxiety. With more frequent RLE the prevalence or symptoms of depression increased in ss carriers. Although CHA failed to show an interaction with 5-HTTLPR, in young subjects CHA sensitized towards the depression promoting effect of even mild RLE. Furthermore, the direct association of anxiety with the s allele was driven by young (\(\leq\)30) individuals. Limitations Our study is cross-sectional and applies self-report questionnaires.

Methods: The circle of experts was increased, general aspects were implemented and the state of the art was updated. Particular emphasis was dedicated to coronary heart diseases (CHD), heart rhythm diseases and heart failure because to date the evidence-based clinical knowledge is most advanced in these particular areas. Differences between men and women and over the life span were considered in the recommendations as were influences of cognitive capability and the interactive and synergistic impact of classical somatic risk factors on the affective comorbidity in heart disease patients. Results: A IA recommendation (recommendation grade I and evidence grade A) was given for the need to consider psychosocial risk factors in the estimation of coronary risks as etiological and prognostic risk factors. Furthermore, for the recommendation to routinely integrate psychosocial patient management into the care of heart surgery patients because in these patients, comorbid affective disorders (e.g. depression, anxiety and post-traumatic stress disorder) are highly prevalent and often have a malignant prognosis. A IB recommendation was given for the treatment of psychosocial risk factors aiming to prevent the onset of CHD, particularly if the psychosocial risk factor is harmful in itself (e.g. depression) or constrains the treatment of the somatic risk factors. Patients with acute and chronic CHD should be offered anti-depressive medication if these patients suffer from medium to severe states of depression and in this case medication with selective reuptake inhibitors should be given. In the long-term course of treatment with implanted cardioverter defibrillators (ICDs) a subjective health technology assessment is warranted. In particular, the likelihood of affective comorbidities and the onset of psychological crises should be carefully considered. Conclusions: The present state of the art paper presents an update of current empirical evidence in psychocardiology. The paper provides evidence-based recommendations for the integration of psychosocial factors into cardiological practice and highlights areas of high priority. The evidence for estimating the efficiency for psychotherapeutic and psychopharmacological interventions has increased substantially since the first release of the policy document but is, however, still weak.

Neben Umwelt- und psychosozialen Faktoren zeigen Studien eine signifikante famili{\"a}re H{\"a}ufung und lassen eine genetische Komponente mit einer Heritabilit{\"a}t in einem Bereich von 30-60 \% vermuten. Da hierbei am ehesten von einem komplexen Zusammenspiel verschiedenster Gene mit unterschiedlicher Relevanz auszugehen ist, stellen miRNAs eine bedeutende Gr{\"o}ße dar, da sie es verm{\"o}gen auf transkriptioneller Ebene Einfluss auf die Regulierung einer Vielzahl von Genen zu nehmen. Verschiedene Aspekte liefern Hinweise darauf, dass eine Neurotransmitterdysregulation eine wichtige Komponente in der Pathogenese von Angsterkrankungen einnimmt - insbesondere ver{\"a}nderte noradrenerge Signalwege sind hierbei entscheidend beteiligt. Dies macht den Noradrenalin-Transporter bzw. SLC6A2 zu einem interessanten Kandidatengen, und stellt die Bezugsgr{\"o}ße der angestellten Untersuchungen in dieser Arbeit dar. miRNAs, welche die SLC6A2-Expression modulieren, k{\"o}nnen somit Einfluss auf zentrale Verarbeitungswege von Angst nehmen. Im ersten Teil der vorliegenden Arbeit wurden potentielle miRNA-Regulatoren von SLC6A2 in silico ermittelt und in einem weiteren Schritt in vitro {\"u}berpr{\"u}ft. Zehn der miRNAs (hsa-miR-378g, hsa-miR-330-5p, hsa-miR-4781-5p, hsa-miR664b-3p, hsa-miR-4715-3p, hsa-miR-579-3p, hsa-miR-3921, hsa-miR-3622b-5p, hsa-miR-4773, hsa-miR-532-3p) zeigten hierbei eine relevante Abnahme der Luciferase-Aktivit{\"a}t als Hinweis auf ihre funktionelle Relevanz und stellen damit die Basis der nachfolgenden Untersuchungen dar. Im zweiten Teil der Arbeit wurden Einzelbasenpolymorphismen im Bereich der zuvor ermittelten miRNA-Gene sowie eines SNP innerhalb der 3'-UTR von SLC6A2 mittels Fall-Kontroll-Studie in einer Population von Patienten mit Panikst{\"o}rung und entsprechenden Kontrollen untersucht. Eine nominelle Assoziation ließ sich f{\"u}r das (minor) T-Allel von rs2910931 (stromaufw{\"a}rts von MIR579) (p-allel = 0,004) sowie das (major) A-Allel von rs2582372 (p-allel = 0,023) feststellen.

To examine whether such anxiety-modulated behaviors are conserved in humans, we re-translated this paradigm to a human setting using virtual reality in a Cave Automatic Virtual Environment (CAVE) system. In two studies, we examined whether the EPM exploration behavior of humans is modulated by their trait anxiety and also assessed the individuals' levels of acrophobia (fear of height), claustrophobia (fear of confined spaces), sensation seeking, and the reported anxiety when on the maze. First, we constructed an exact virtual copy of the animal EPM adjusted to human proportions. In analogy to animal EPM studies, participants (N = 30) freely explored the EPM for 5 min. In the second study (N = 61), we redesigned the EPM to make it more human-adapted and to differentiate influences of trait anxiety and acrophobia by introducing various floor textures and lower walls of closed arms to the height of standard handrails. In the first experiment, hierarchical regression analyses of exploration behavior revealed the expected association between open arm avoidance and Trait Anxiety, an even stronger association with acrophobic fear. In the second study, results revealed that acrophobia was associated with avoidance of open arms with mesh-floor texture, whereas for trait anxiety, claustrophobia, and sensation seeking, no effect was detected. Also, subjects' fear rating was moderated by all psychometrics but trait anxiety. In sum, both studies consistently indicate that humans show no general open arm avoidance analogous to rodents and that human EPM behavior is modulated strongest by acrophobic fear, whereas trait anxiety plays a subordinate role. Thus, we conclude that the criteria for cross-species validity are met insufficiently in this case. Despite the exploratory nature, our studies provide in-depth insights into human exploration behavior on the virtual EPM.}, language = {en} } @article{NeubertSchlechtMengetal.2023, author = {Neubert, Sven and Schlecht, Sina and Meng, Karin and Rabe, Antonia and Jentschke, Elisabeth}, title = {Effects of a video sequence based intervention on anxiety, fatigue and depression in cancer patients: results of a randomized controlled trial}, series = {Integrative Cancer Therapies}, volume = {22}, journal = {Integrative Cancer Therapies}, issn = {1552-695X}, doi = {10.1177/15347354231153172}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-304581}, year = {2023}, abstract = {Background: Cancer patients often suffer from psychological symptoms and need psychological support. Especially during the COVID-19 pandemic, eHealth interventions might be helpful to overcome the obstacles of the pandemic. This study evaluates the effectiveness of a video sequence-based eHealth intervention on anxiety, fatigue, and depression in cancer patients. Methods: Patients (N = 157) with different tumor entities were randomly assigned to the video intervention group (IG) and the waiting control group (CG). Patients in the IG received a video intervention comprising 8 video sequences over 4 weeks. The videos included psychoeducation on distress and psychological symptoms, Acceptance and Commitment Therapy elements, and Yoga and Qigong exercises. Patients' anxiety and fear of progression (primary outcomes) and secondary outcomes were assessed before randomization (T1) and after the end of the intervention for IG or the waiting period for CG (T2) using self-reported questionnaires (GAD-7, PA-F-KF, EORTC QLQ-FA12, PHQ-8). Results: Patients of the IG showed no significant improvement in anxiety (GAD-7; P = .75), fear of progression (FoP-Q-SF; P = .29), fatigue (EORTC QLQ-FA12; P = .72), and depression (PHQ-8; P = .95) compared to patients in the waiting CG. However, symptoms of anxiety, fatigue, and depression decreased in both groups. Exploratory subgroup analysis regarding sex, therapy status, therapy goal, and tumor entity showed no effects. Overall, the intervention had a high level of acceptance. Conclusions: The video intervention was ineffective in reducing the psychological burden compared to a waiting CG. The findings support prior observations of the value of therapeutic guidance and promoting self-management for improving patients' psychological burdens.

There is a clear relationship between disturbances induced by stressful stimuli, especially long-lasting stimuli, and cognitive deficits in rodent models of affective disorders. Regular physical activity has a positive effect on the central nervous system (CNS) functions, contributes to an improvement in mood and of cognitive abilities (including memory and learning), and is correlated with an increase in the expression of the neurotrophic factors and markers of synaptic plasticity as well as a reduction in the inflammatory factors. Studies published so far show that the energy challenge caused by physical exercise can affect the CNS by improving cellular bioenergetics, stimulating the processes responsible for the removal of damaged organelles and molecules, and attenuating inflammation processes. Regular physical activity brings another important benefit: increased stress robustness. The evidence from animal studies is that a sedentary lifestyle is associated with stress vulnerability, whereas a physically active lifestyle is associated with stress resilience. Here, we have performed a comprehensive PubMed Search Strategy for accomplishing an exhaustive literature review. In this review, we discuss the findings from experimental studies on the molecular and neurobiological mechanisms underlying the impact of exercise on brain resilience.

Survey of staff composition and retrospective analysis of PCT patient charts in both PCTs were conducted. Patients self-assessed their symptoms in PCT-W and in Radiation Oncology W{\"u}rzburg (RO-W). The (negative) quality indicator 'percentage of deceased hospitalised patients with PCT contact for less than 3 days before death' (Earle in Int J Qual Health Care 17(6):505-509, 2005) was analysed. Both PCTs follow a multidisciplinary team approach. PCT-N saw 410 cancer patients versus 853 patients for PCT-W (22.8\% non-cancer patients).

PCT-N was engaged in co-management longer than PCT-W (mean 20.7 days, range 1-102 versus mean 4.9 days, range 1-48). The most frequent patient-reported psychological symptom was anxiety (family anxiety: 98.3\% PCT-W and 88.7\% RO-W, anxiety 97.9\% PCT-W and 85.9\% RO-W), followed by depression (98.2\% PCT-W and 80.3\% RO-W).

Following mood manipulation, subjects rated five different oral stimuli, appearing sweet, umami, sour, bitter, fatty, which were delivered at five different concentrations each. Depression levels were assessed with Beck's Depression Inventory (BDI) and anxiety levels were assessed via the Spielberger's STAI-trait and state questionnaire. Overall, subjects were able to track the concentrations of the stimuli correctly, yet depression level affected taste ratings. First, depression scores were positively correlated with sucrose ratings. Second, subjects with depression scores above the sample median rated sucrose and quinine as more intense after mood induction (positive, negative and neutral). Third and most important, the group with enhanced depression scores did not rate low and high fat stimuli differently after positive or negative mood induction, whereas, during baseline or during the non-emotional neutral condition they rated the fat intensity as increasing with concentration. Consistent with others' prior observations we also found that sweet and bitter stimuli at baseline were rated as more intense by participants with higher anxiety scores and that after positive and negative mood induction, citric acid was rated as stronger tasting compared to baseline. The observation that subjects with mild subclinical depression rated low and high fat stimuli similarly when in positive or negative mood is novel and likely has potential implications for unhealthy eating patterns.

Electrocardiography, histology and FACS of inflammatory cells revealed no abnormalities. However, gene expression of inflammation-related cytokines (TGF-β, TNF-α, IL-6) and MMP-2, a protein involved in the breakdown of extracellular matrix, was significantly increased in 5-HTT-/- mice after MI.

GLRB encodes the glycine receptor (GlyRs) β subunit. The identified SNPs are localized within the gene flanking regions (3′ and 5′ UTRs) and intronic regions. It was suggested that these nucleotide polymorphisms modify GlyRs expression and phenotypic behavior in humans contributing to an anxiety phenotype as a mild form of hyperekplexia. Hyperekplexia is a human neuromotor disorder with massive startle phenotypes due to mutations in genes encoding GlyRs subunits. GLRA1 mutations have been more commonly observed than GLRB mutations. If an anxiety phenotype contributes to the hyperekplexia disease pattern has not been investigated yet. Here, we compared two mouse models harboring either a mutation in the murine Glra1 or Glrb gene with regard to anxiety and startle phenotypes. Homozygous spasmodic animals carrying a Glra1 point mutation (alanine 52 to serine) displayed abnormally enhanced startle responses. Moreover, spasmodic mice exhibited significant changes in fear-related behaviors (freezing, rearing and time spent on back) analyzed during the startle paradigm, even in a neutral context. Spastic mice exhibit reduced expression levels of the full-length GlyRs β subunit due to aberrant splicing of the Glrb gene. Heterozygous animals appear normal without an obvious behavioral phenotype and thus might reflect the human situation analyzed in the GWAS study on agoraphobia and startle. In contrast to spasmodic mice, heterozygous spastic animals revealed no startle phenotype in a neutral as well as a conditioning context. Other mechanisms such as a modulatory function of the GlyRs β subunit within glycinergic circuits in neuronal networks important for fear and fear-related behavior may exist. Possibly, in human additional changes in fear and fear-related circuits either due to gene-gene interactions e.g., with GLRA1 genes or epigenetic factors are necessary to create the agoraphobia and in particular the startle phenotype.}, language = {en} } @article{SchieleZieglerKollertetal.2018, author = {Schiele, Miriam A. and Ziegler, Christiane and Kollert, Leonie and Katzorke, Andrea and Schartner, Christoph and Busch, Yasmin and Gromer, Daniel and Reif, Andreas and Pauli, Paul and Deckert, J{\"u}rgen and Herrmann, Martin J. and Domschke, Katharina}, title = {Plasticity of Functional MAOA Gene Methylation in Acrophobia}, series = {International Journal of Neuropsychopharmacology}, volume = {21}, journal = {International Journal of Neuropsychopharmacology}, number = {9}, doi = {10.1093/ijnp/pyy050}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-228571}, pages = {822-827}, year = {2018}, abstract = {Epigenetic mechanisms have been proposed to mediate fear extinction in animal models.

The big efforts of this multi-center study were not only to evaluate the caregivers' burden and to identify its predictors, but it also should provide a specific understanding of the needs of ALS patients' CGs and fill the gap of knowledge on their personal and work lives. Using standardized questionnaires, primary data from patients and their main informal CGs (n = 249) were collected. Patients' functional status and disease severity were evaluated using the Barthel Index, the revised Amyotrophic Lateral Sclerosis Functional Rating Scale (ALSFRS-R) and the King's Stages for ALS. The caregivers' burden was recorded by the Zarit Burden Interview (ZBI). Comorbid anxiety and depression of caregivers were assessed by the Hospital Anxiety and Depression Scale. Additionally, the EuroQol Five Dimension Five Level Scale evaluated their health-related quality of life. The caregivers' burden was high (mean ZBI = 26/88, 0 = no burden, ≥24 = highly burdened) and correlated with patients' functional status (r\(_p\) = -0.555, p < 0.001, n = 242). It was influenced by the CGs' own mental health issues due to caregiving (+11.36, 95\% CI [6.84; 15.87], p < 0.001), patients' wheelchair dependency (+9.30, 95\% CI [5.94; 12.66], p < 0.001) and was interrelated with the CGs' depression (r\(_p\) = 0.627, p < 0.001, n = 234), anxiety (r\(_p\) = 0.550, p < 0.001, n = 234), and poorer physical condition (r\(_p\) = -0.362, p < 0.001, n = 237). Moreover, female CGs showed symptoms of anxiety more often, which also correlated with the patients' impairment in daily routine (r\(_s\) = -0.280, p < 0.001, n = 169). As increasing disease severity, along with decreasing autonomy, was the main predictor of caregiver burden and showed to create relevant (negative) implications on CGs' lives, patient care and supportive therapies should address this issue. Moreover, in order to preserve the mental and physical health of the CGs, new concepts of care have to focus on both, on not only patients but also their CGs and gender-associated specific issues. As caregiving in ALS also significantly influences the socioeconomic status by restrictions in CGs' work lives and income, and the main reported needs being lack of psychological support and a high bureaucracy, the situation of CGs needs more attention.

Functional assessment of c-Fos after associated foot shock, electrophysiological recordings of GABAergic synaptic transmission, differential expression of the Slc6a4 gene in serotonergic neurons were combined with locomotor and anxiety-like measurements in different contextual settings. Our findings indicate that constitutive Tph2 inactivation and consequential lack of 5-HT synthesis in Tph2 null mutant mice (Tph2\(^{-/-}\)) results in increased freezing to associated foot shock and a differential c-Fos activity pattern in the basolateral complex of the amygdala. This is accompanied by altered GABAergic transmission as observed by recordings of inhibitory postsynaptic currents on principal neurons in the basolateral nucleus, which may explain increased fear associated with hyperlocomotion and escape-like responses in aversive inescapable contexts. In contrast, lifelong 5-HT deficiency as observed in Tph2 heterozygous mice (Tph\(^{+/-}\)) is able to be compensated through reduced GABAergic transmission in the basolateral nucleus of the amygdala based on Slc6a4 mRNA upregulation in subdivisions of dorsal raphe neurons. This results in increased activity of the basolateral nucleus of the amygdala due to associated foot shock. In conclusion, our results reflect characteristic syndromal dimensions of panic disorder and agoraphobia. Thus, constitutive lack of 5-HT synthesis influence the risk for anxiety- and stressor-related disorders including panic disorder and comorbid agoraphobia through the absence of GABAergic-dependent compensatory mechanisms in the basolateral nucleus of the amygdala.}, language = {en} } @article{WalterGrussNeidlingeretal.2020, author = {Walter, Steffen and Gruss, Sascha and Neidlinger, Jana and Stross, Isabelle and Hann, Alexander and Wagner, Martin and Seufferlein, Thomas and Walter, Benjamin}, title = {Evaluation of an Objective Measurement Tool for Stress Level Reduction by Individually Chosen Music During Colonoscopy—Results From the Study "ColoRelaxTone"}, series = {Frontiers in Medicine}, volume = {7}, journal = {Frontiers in Medicine}, doi = {10.3389/fmed.2020.00525}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-212337}, year = {2020}, abstract = {Background and Aims: Colonoscopy as standard procedure in endoscopy is often perceived as uncomfortable for patients. Patient's anxiety is therefore a significant issue, which often lead to avoidance of participation of relevant examinations as CRC-screening. Non-pharmacological anxiety management interventions such as music might contribute to relaxation in the phase prior and during endoscopy. Although music's anxiolytic effects have been reported previously, no objective measurement of stress level reduction has been reported yet. Focus of this study was to evaluate the objective measurement of the state of relaxation in patients undergoing colonoscopy. Methods: Prospective study (n = 196) performed at one endoscopic high-volume center. Standard colonoscopy was performed in control group. Interventional group received additionally self-chosen music over earphones. Facial Electromyography (fEMG) activity was obtained. Clinician Satisfaction with Sedation Instrument (CSSI) and Patients Satisfaction with Sedation Instrument (PSSI) was answered by colonoscopists and patients, respectively. Overall satisfaction with music accompanied colonoscopy was obtained if applicable. Results: Mean difference measured by fEMG via musculus zygomaticus major indicated a significantly lower stress level in the music group [7.700(±5.560) μV vs. 4.820(±3.330) μV; p = 0.001]. Clinician satisfaction was significantly higher with patients listening to music [82.69(±15.04) vs. 87.3(±15.02) pts.; p = 0.001]. Patient's satisfaction was higher but did not differ significantly. Conclusions: We conclude that self-chosen music contributes objectively to a reduced stress level for patients and therefore subjectively perceived satisfaction for endoscopists. Therefore, music should be considered as a non-pharmacological treatment method of distress reduction especially in the beginning of endoscopic procedures.}, language = {en} } @article{WiemerRaunerStegmannetal.2021, author = {Wiemer, Julian and Rauner, Milena M. and Stegmann, Yannik and Pauli, Paul}, title = {Reappraising fear: is up-regulation more efficient than down-regulation?}, series = {Motivation and Emotion}, volume = {45}, journal = {Motivation and Emotion}, number = {2}, issn = {1573-6644}, doi = {10.1007/s11031-021-09871-9}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-269187}, pages = {221-234}, year = {2021}, abstract = {Catastrophizing thoughts may contribute to the development of anxiety, but functional emotion regulation may help to improve treatment. No study so far directly compared up- and down-regulation of fear by cognitive reappraisal. Here, healthy individuals took part in a cued fear experiment, in which multiple pictures of faces were paired twice with an unpleasant scream or presented as safety stimuli. Participants (N = 47) were asked (within-subjects) to down-regulate, to up-regulate and to maintain their natural emotional response. Valence and arousal ratings indicated successful up- and down-regulation of the emotional experience, while heart rate and pupil dilation increased during up-regulation, but showed no reduction in down-regulation. State and trait anxiety correlated with evaluations of safety but not threat stimuli, which supports the role of deficient safety learning in anxiety. Reappraisal did not modulate this effect. In conclusion, this study reveals evidence for up-regulation effects in fear, which might be even more efficient than down-regulation on a physiological level and highlights the importance of catastrophizing thoughts for the maintenance of fear and anxiety.}, language = {en} } @article{WongPittig2022, author = {Wong, Alex H.

However, safety behavior in anxiety-related disorders is often costly, and persists even the situation does not entail realistic threat. Individuals can engage in safety behavior to varying extents, however, these behaviors are typically measured dichotomously (i.e., to execute or not). To better understand the nuances of safety behavior, this study developed a dimensional measure of safety behavior that had a negative linear relationship with the admission of an aversive outcome. In two experiments, a Reward group receiving fixed or individually calibrated incentives competing with safety behavior showed reduced safety behavior than a Control group receiving no incentives. This allowed extinction learning to a previously learnt warning signal in the Reward group (i.e., updating the belief that this stimulus no longer signals threat). Despite the Reward group exhibited extinction learning, both groups showed a similar increase in fear to the warning signal once safety behavior was no longer available. This null group difference was due to some participants in the Reward group not incentivized enough to disengage from safety behavior. Dimensional assessment revealed a dissociation between low fear but substantial safety behavior to a safety signal in the Control group. This suggests that low-cost safety behavior does not accurately reflect the fear-driven processes, but also other non-fear-driven processes, such as cost (i.e., engage in safety behavior merely because it bears little to no cost). Pinpointing both processes is important for furthering the understanding of safety behavior.}, language = {en} } @article{ZacherWollankaSaueretal.2023, author = {Zacher, Magdalena and Wollanka, Nele and Sauer, Christina and Haßtenteufel, Kathrin and Wallwiener, Stephanie and Wallwiener, Markus and Maatouk, Imad}, title = {Prenatal paternal depression, anxiety, and somatic symptom burden in different risk samples: an explorative study}, series = {Archives of Gynecology and Obstetrics}, volume = {307}, journal = {Archives of Gynecology and Obstetrics}, number = {4}, doi = {10.1007/s00404-022-06612-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-324465}, pages = {1255-1263}, year = {2023}, abstract = {Purpose Growing evidence implies that transition to parenthood triggers symptoms of mental burden not only in women but likewise in men, especially in high-risk pregnancies. This is the first study that examined and compared the prevalence rates of depression, anxiety, and somatic symptom burden of expectant fathers who face different risk situations during pregnancy. Methods Prevalence rates of paternal depression (Edinburgh postnatal depression scale), anxiety (generalized anxiety disorder seven), and somatic symptom burden (somatic symptom scale eight) were examined in two risk samples and one control group in the third trimester of their partners' pregnancy: risk sample I (n = 41) consist of expectant fathers whose partners were prenatally hospitalized due to medical complications; risk sample II (n = 52) are fathers whose partners were prenatally mentally distressed; and control group (n = 70) are those non-risk pregnancies. Results On a purely descriptive level, the data display a trend of higher symptom burden of depression, anxiety, and somatic symptoms in the two risk samples, indicating that expectant fathers, whose pregnant partners were hospitalized or suffered prenatal depression, were more prenatally distressed. Exploratory testing of group differences revealed an almost three times higher prevalence rate of anxiety in fathers whose partner was hospitalized (12.2\%) compared to those non-risks (4.3\%). Conclusion Results underline the need for screening implementations for paternal prenatal psychological distress, as well as specific prevention and treatment programs, especially for fathers in risk situations, such as their pregnant partners' prenatal hospitalization.
