Pain associated with specific anxiety and depressive disorders in a nationally representative population sample

Beesdo, Katja, Jacobi, Frank, Hoyer, Jürgen, Low, Nancy C. P., Höfler, Michael, Wittchen, Hans-Ulrich January 2010 (has links)
Objective: To examine in a nationally representative sample (a) the differential association of specific anxiety and depressive disorders defined according to DSM-IV with pain disorder (PD) and pain symptoms, and (b) whether pain-associated anxiety and depressive disorders and their comorbidity have different implications in terms of impairment, disability, health care utilization, and substance use. Method: A nationally representative community study was conducted in Germany. Symptoms, syndromes and diagnoses of mental disorders, and pain were assessed in N = 4,181 participants aged 18–65 years using the DSM-IV/M-CIDI. Results: Logistic regressions revealed that pain is associated with both specific anxiety and depressive disorders, with increasing significant odds ratios (OR) for medically explained pain symptoms (EPS; OR range: 1.9–2.0), to unexplained pain symptoms (UPS; OR range: 2.4–7.3), to PD (OR range: 3.3–14.8). PD and UPS persistently showed associations after adjusting for comorbid other anxiety and depressive disorders and physical illnesses. All types of pain, particularly PD/UPS, are associated with decreased quality of life, greater impairment in role functioning, disability, health care utilization, and substance use. Depressive disorders, even more so anxiety disorders and their comorbidity account for a substantial proportion of variance in these functional correlates. Conclusions: Pain is strongly associated with specific anxiety and depressive disorders. In light of the individual and societal burden due to pain, and the demonstrated role of comorbid anxiety or/and depression, our results call for further investigation of the underlying mechanisms for this association as well as targeted treatments for these comorbidities.

Broadening the definition of generalized anxiety disorder: Effects on prevalence and associations with other disorders in the National Comorbidity Survey Replication

Ruscio, Ayelet Meron, Chiu, Wai Tat, Roy-Byrne, Peter, Stang, Paul E., Stein, Dan J., Wittchen, Hans-Ulrich, Kessler, Ronald C. January 2007 (has links)
Concerns have been raised that the DSM-IV requirements of 6-month duration, excessive worry, and three associated symptoms exclude a substantial number of people with clinically significant anxiety from a diagnosis of generalized anxiety disorder (GAD). We examined the implications of relaxing these three criteria for the estimated prevalence and predictive validity of GAD using nationally representative data from the US National Comorbidity Survey Replication. Relaxing all three criteria more than doubles the estimated prevalence of GAD. Broadly defined GAD significantly predicts the subsequent first onset of a wide range of temporally secondary disorders. The odds of secondary disorders are somewhat smaller for broadly defined than DSM-IV GAD, though few of these differences are statistically significant. Results suggest that subthreshold manifestations of GAD are significantly related to elevated risk of subsequent psychopathology. Further research is needed to determine whether broadening the current diagnostic criteria results in a more valid characterization of GAD.

Social phobia: diagnosis and epidemiology, neurobiology and pharmacology, comorbidity and treatment

Brunello, Nicoletta, den Boer, Johan A., Judd, Lewis L., Kasper, Siegfried, Kelsey, Jeffrey E., Lader, Malcolm, Lecrubier, Yves, Lepine, Jean-Pierre, Lydiard, R. B., Mendlewicz, Julien, Montgomery, Stuart A., Racagni, Giorgio, Stein, Murray B., Wittchen, Hans-Ulrich January 2000 (has links)
Social phobia is a common disorder associated with significant psychosocial impairment, representing a substantial public health problem largely determined by the high prevalence, and the lifelong chronicity. Social phobia starts in early childhood or adolescence and is often comorbid with depression, other anxiety disorders, alcohol and substance abuse or eating disorders. This cascade of comorbidity, usually secondary to social phobia, increases the disability associated with the condition. The possibility that social phobia may be a trigger for later developing comorbid disorders directs attention to the need for early effective treatment as a preventive measure. The most recent drug class to be investigated for the psychopharmacological treatment of social phobia is the SSRI group for which there is growing support. The other drug classes that have been evaluated are monoamine oxidase inhibitors (MAOIs), benzodiazepines, and beta-blockers. The SSRIs represent a new and attractive therapeutic choice for patients with generalized social phobia. Recently the first, large scale, placebo-controlled study to assess the efficacy of drug treatment in generalized social phobia has been completed with paroxetine. Paroxetine was more effective in reducing the symptoms than placebo and was well tolerated. Many now regard SSRIs as the drugs of choice in social phobia because of their effectiveness and because they avoid the problems of treatment with benzodiazepines or classical MAOIs.

Implikationen von Komorbidität bei Angsstörungen - Ein kritischer Überblick

Wittchen, Hans-Ulrich, Vossen, A. January 1995 (has links)
Der Beitrag diskutiert kritische theoretische und praktische Aspekte der Komorbidität auf der Grundlage von klinischen und epidemiologischen Befunden zur Komorbidität. Angststörungen weisen statistisch hochsignifikante Assoziationen untereinander sowie mit affektiven, psychotischen Störungen, Eβstörungen sowie Substanzstörungen und Persönlichkeitsstörungen auf. Sie gehen zumeist eindeutig den komorbiden Störungen voraus, so daβ Angststörungen als Risikofaktoren für viele andere Formen psychischer Störungen angesehen werden können. Die möglicherweise kausalen pathogenetischen Mechanismen sind jedoch nach wie vor umstritten und sind offensichtlich vielfältig. Der Beitrag diskutiert vor diesem Hintergrund besonders die möglicherweise kritische Bedeutung von Panikattacken als zentraler «Vulnerabilitätsmarker» nicht nur für die Entwicklung von Angststörungen, sondern auch für affektive Erkrankungen. Hier konnte z.B. nachgewiesen werden, daβ initiale Panikattacken nicht nur die Wahrscheinlichkeit für Rückfälle sekundärer Depressionen erhöhen, sondern auch signifikant die Häufigkeit und Länge depressiver Phasen beeinflussen. Die Vielzahl differenzierter Befunde legt nahe, Komorbidität bei der Eingangs- und Verlaufsdiagnostik ebenso wie bei der Indikationsstellung umfassender zu berücksichtigen.

Evidence That Psychotic Symptoms Are Prevalent in Disorders of Anxiety and Depression, Impacting on Illness Onset, Risk, and Severity – Implications for Diagnosis and Ultra-High Risk Research

Wigman, Johanna T. W., van Nierop, Martine, Vollebergh, Wilma A. M., Lieb, Roselind, Beesdo-Baum, Katja, Wittchen, Hans-Ulrich, van Os, Jim January 2012 (has links)
Background: It is commonly assumed that there are clear lines of demarcation between anxiety and depressive disorders on the one hand and psychosis on the other. Recent evidence, however, suggests that this principle may be in need of updating. Methods: Depressive and/or anxiety disorders, with no previous history of psychotic disorder, were examined for the presence of psychotic symptoms in a representative community sample of adolescents and young adults (Early Developmental Stages of Psychopathology study; n=3021). Associations and consequences of psychotic symptomatology in the course of these disorders were examined in terms of demographic distribution, illness severity, onset of service use, and risk factors. Results: Around 27% of those with disorders of anxiety and depression displayed one or more psychotic symptoms, vs 14% in those without these disorders (OR 2.23, 95% CI 1.89–2.66, P < .001). Presence as compared with nonpresence of psychotic symptomatology was associated with younger age (P < .0001), male sex (P < .0058), and poorer illness course (P < .0002). In addition, there was greater persistence of schizotypal (P < .0001) and negative symptoms (P < .0170), more observable illness behavior (P < .0001), greater likelihood of service use (P < .0069), as well as more evidence of familial liability for mental illness (P < .0100), exposure to trauma (P < .0150), recent and more distant life events (P < .0006–.0244), cannabis use (P < .0009), and any drug use (P < .0008). Conclusion: Copresence of psychotic symptomatology in disorders of anxiety and depression is common and a functionally and etiologically highly relevant feature, reinforcing the view that psychopathology is represented by a network or overlapping and reciprocally impacting dimensional liabilities.

Konsiliarpsychiatrie im Allgemeinkrankenhaus

Diefenbacher, Albert 02 July 2002 (has links)
Die vorliegende Arbeit beschäftigt sich mit der Tätigkeit konsiliarpsychiatrischer Dienste am Allgemeinkrankenhaus. In einem historischen Abriß wird zunächst die Integration des psychiatrischen Fachgebiets in die Allgemeinkrankenhäuser als wesentliche Bedingung für die Entwicklung der Konsiliarpsychiatrie am Beispiel der USA dargestellt, gefolgt von europäischen Perspektiven und der Entwicklung in Deutschland, unter besonderer Berücksichtigung der Psychiatrie-Enquête. Anschließend werden Aspekte somatopsychischer Komorbidät als Grundlage der Konsiliarpsychiatrie und ihre Implikationen für Diagnostik und Therapie skizziert. Vorschläge zur Bestimmung des Bedarfs der konsiliarpsychiatrischen Versorgung werden diskutiert. Das Spektrum konsiliar-liaisonpsych-iatrischer Versorgungsmöglichkeiten wird dargestellt, Interventionsmöglichkeiten mit ihren differentia specifica im Setting des Allgemeinkrankenhauses am Beispiel von supportiver Psychotherapie und Psychopharmakatherapie bei körperlich kranken Patienten werden verdeutlicht. Im empirischen Teil wird auf Grundlage einer Längsschnittstudie über einen 10jährigen Be-obachtungszeitraum eines amerikanischen, sowie einer Vergleichsstudie der Tätigkeit eines deutschen und eines amerikanischen Konsildienstes über einen einjährigen Beobachtungszeitraum versucht, einen Kernbereich konsiliarpsychiatrischer Tätigkeit am Allgemeinkrankenhaus zu definieren. In der Längsschnittuntersuchung wurde ein zeitüberdauernder Bereich konsiliarpsychiatrischer Tätigkeit identifiziert, der im Vergleich mit ähnlichen, allerdings weniger detaillierten Studien (Lipowski & Wolston 1981, Paddison et al. 1989) ebenfalls überwiegend Gemeinsamkeiten deutlich werden läßt. Auch die vergleichende Querschnittsuntersuchung zeigte, daß psychiatrische Konsiliartätigkeit über nationale Grenzen hinweg eine Reihe von Gemeinsamkeiten aufweist. Auch dies konnte im Vergleich mit anderen Studien bestätigt werden (vgl. Übersichten bei Hengeveld et al. 1984, Diefenbacher 1999, Huyse et al. 1997). Anschließend werden Veränderungen im Gefolge der Tätigkeit eines neu beginnenden psychiatrischen Konsiliars über einen einjährigen Beobachtungszeitraum untersucht und im Hinblick auf die Implementation eines Konsildiensten auf für die konsiliarpsychiatrische Praxis bzw. Interventionsforschung wichtige Parameter wie z.B. Zusammenarbeit mit den Stationsteams und Beeinflussung von Krankenhausverweildauer und Zeitintervall zwischen stationärer Aufnahme und Konsilanforderung diskutiert. Zusammenfassend wird ein Kernbereich konsiliarpsychiatrischer Tätigkeit beschrieben, von dem erwartet wird, daß er für die nahe Zukunft konstant bleibt und somit als Orientierungshilfe für administrative und evaluative Zwecke dienen kann. Abschließend werden Perspektiven weiterer Forschung in der Konsiliarpsychiatrie diskutiert und auf Aspekte der Fort- und Weiterbildung im psychiatrischen Konsiliar-Liaisondienst in der psychiatrischen Facharztweiterbildung, sowie auf Schnittstellen für eine mögliche Zusammenarbeit mit dem hausärztlichen Bereich eingegangen. / Psychiatric consultation-liaison (c-l) service delivery in the general hospital is the topic of this study. In the first part, an historical outline of the development of psychiatric c-l-services in the USA is presented, followed by recent developments in Europe and Germany, with special emphasis - for the latter - of the impact of the so-called "Psychiatrie-Enquête" (1975) on the implementation of psychiatric departments in general hospitals since the 1980s. The issue of somato-psychic comorbidity of general hospital inpatients, the very reason of existence of c-l-psychiatry, is discussed, as are its implications for diagnosis and treatment. Proposals for the evaluation of need for such services are presented, as is the scope of c-l-psychiatric interventions and their special nature with the example of supportive psychotherapy and psychopharmaco-therapy in the medically and psychiatrically ill inpatient. The second empirical part consists of a 10-year-longitudinal study of a c-l-psychiatric service in New York City, and a comparative cross-sectional study (over a 1-year-period) of a German and an American c-l-psychiatric service in order to delineate a common core of psychiatric c-l-service delivery in the general hospital. In both studies, a cross-national common core and a time stable course over time, respectively, are identified and then discussed in comparison to other less detailed studies (e.g. Lipowski & Wolston 1981, Hengeveld et al. 1984, Huyse et al. 1997). In addition, the implementation phase of a newly started psychiatric c-l-service is studied over a 1-year-period with regard to variables important for c-l-psychiatric intervention studies, such as influence on length of stay in hospital, lagtime between admission to hospital and day of consultation request, and cooperation with staff. In conclusion, a core field of psychiatric c-l-service delivery in the general hospital is identified, that is expected to remain stable in years to come and thus might help as an orientation for administrative and evaluative purposes. Finally, perspectives for further research in the field, for training and education, and for the cooperation with primary care doctors are discussed.

A striking pattern of cortisol non-responsiveness to psychosocial stress in patients with panic disorder with concurrent normal cortisol awakening responses

Petrowski, Katja, Herold, Ulf, Joraschky, Peter, Wittchen, Hans-Ulrich, Kirschbaum, Clemens 23 April 2013 (has links) (PDF)
Background: Subtle and inconsistent differences in hypothalamic-pituitary-adrenal (HPA) axis activity have been reported for patients with panic disorder. While these patients show little or no alterations in basal ACTH and cortisol levels, it has been hypothesized that HPA hyperresponsivity was a trait in panic patients when exposed to novel and uncontrollable stimulation. Methods: Thirty-four patients (23 females, mean age 35 yrs) diagnosed with panic disorder were compared to 34 healthy controls matched for age, gender, smoking status, and use of oral contraceptives. Both groups were exposed twice to a potent laboratory stress protocol, the Trier Social Stress Test (TSST) on consecutive days. Free salivary cortisol levels and heart rate responses were repeatedly measured before and following the TSST. In addition, the cortisol awakening response (CAR) was assessed to further investigate HPA reactivity in PD patients. Results: While the TSST induced similar heart rate stress responses in both groups, cortisol responses were clearly absent in the panic patients with normal responses in the controls (F(1.96, 66) = 20.16; p < 0.001). No differences in basal cortisol levels were observed in the extended baseline period. The same cortisol stress non-response patterns were observed when patients with/without comorbid depression, or with/without psychotropic medication were compared. In contrast to their non-response to the psychosocial stressor, panic patients showed a significant CAR. Conclusion: These findings provide strong evidence to suggest that PD patients present with a striking lack of cortisol responsivity to acute uncontrollable psychosocial stress under laboratory conditions. This unresponsiveness of the HPA axis appears to be rather specific, since a normal CAR in the morning could be documented in these patients. Thus, the present results do not support the hypothesis that PD patients show a trait HPA hyperresponsiveness to novel and uncontrollable stimulation. In contrast, the data provide support for a hyporesponsive HPA axis under emotional stress in PD patients.

DSM-IV pain disorder in the general population

Fröhlich, Christine, Jacobi, Frank, Wittchen, Hans-Ulrich 06 February 2013 (has links) (PDF)
Background: Despite an abundance of questionnaire data, the prevalence of clinically significant and medically unexplained pain syndromes in the general population has rarely been examined with a rigid personal-interview methodology. Objective To examine the prevalence of pain syndromes and DSM-IV pain disorder in the general population and the association with other mental disorders, as well as effects on disability and health-care utilization. Methods: Analyses were based on a community sample of 4.181 participants 18–65 years old; diagnostic variables were assessed with a standardized diagnostic interview (M-CIDI). Results: The 12-month prevalence for DSM-IV pain disorder in the general population was 8.1%; more than 53% showed concurrent anxiety and mood disorders. Subjects with pain disorder revealed significantly poorer quality of life, greater disability, and higher health-care utilization rates compared to cases with pain below the diagnostic threshold. The majority had more than one type of pain, with excessive headache being the most frequent type. Conclusions: Even when stringent diagnostic criteria are used, pain disorder ranks among the most prevalent conditions in the community. The joint effects of high prevalence in all age groups, substantial disability, and increased health services utilization result in a substantial total burden, exceeding that of depression and anxiety.
