The epidemiology of panic disorder and agoraphobia in EuropeGoodwin, Renee D., Faravelli, Carlo, Rosi, S., Cosci, F., Truglia, E., Graaf, Ron de, Wittchen, Hans-Ulrich 10 April 2013 (has links) (PDF)
A literature search, in addition to expert survey, was performed to estimate the size and burden of panic disorder in the European Union (EU). Epidemiologic data from EU countries were critically reviewed to determine the consistency of prevalence estimates across studies and to identify the most pressing questions for future research. A comprehensive literature search focusing on epidemiological studies in community and clinical settings in European countries since 1980 was conducted (Medline, Web of Science, Psychinfo). Only studies using established diagnostic instruments on the basis of DSM-III-R or DSM-IV, or ICD-10 were considered. Thirteen studies from a total of 14 countries were identified. Epidemiological findings are relatively consistent across the EU. The 12-month prevalence of panic disorder and agoraphobia without history of panic were estimated to be 1.8% (0.7–2.2) and 1.3% (0.7–2.0) respectively across studies. Rates are twice as high in females and age of first onset for both disorders is in adolescence or early adulthood. In addition to comorbidity with agoraphobia, panic disorder is strongly associated with other anxiety disorders, and a wide range of somatoform, affective and substance use disorders. Even subclinical forms of panic disorder (i.e., panic attacks) are associated with substantial distress, psychiatric comorbidity and functional impairment. In general health primary care settings, there appears to be substantial underdiagnosis and undertreatment of panic disorder. Moreover, panic disorder and agoraphobia are poorly recognized and rarely treated in mental health settings, despite high health care utilization rates and substantial long-term disability.

Agoraphobia and PanicWittchen, Hans-Ulrich, Nocon, Agnes, Beesdo, Katja, Pine, Daniel S., Höfler, Michael, Lieb, Roselind, Gloster, Andrew T. 29 November 2012 (has links) (PDF)
Background: The relationship of panic attacks (PA), panic disorder (PD) and agoraphobia (AG) is controversial. The aim of the current study is to prospectively examine the 10-year natural course of PA, PD and AG in the first three decades of life, their stability and their reciprocal transitions.
Methods: DSM-IV syndromes were assessed via Composite International Diagnostic Interview – Munich version in a 10-year prospective-longitudinal community study of 3,021 subjects aged 14–24 years at baseline.
Results: (1) Incidence patterns for PA (9.4%), PD (with and without AG: 3.4%) and AG (5.3%) revealed differences in age of onset, incidence risk and gender differentiation. (2) Temporally primary PA and PD revealed only a moderately increased risk for subsequent onset of AG, and primary AG had an even lower risk for subsequent PA and PD. (3) In strictly prospective analyses, all baseline groups (PA, PD, AG) had low remission rates (0–23%). Baseline PD with AG or AG with PA were more likely to have follow-up AG, PA and other anxiety disorders and more frequent complications (impairment, disability, help-seeking, comorbidity) as compared to PD without AG and AG without PA.
Conclusions: Differences in incidence patterns, syndrome progression and outcome, and syndrome stability over time indicate that AG exists as a clinically significant phobic condition independent of PD. The majority of agoraphobic subjects in this community sample never experienced PA, calling into question the current pathogenic assumptions underlying the classification of AG as merely a consequence of panic. The findings point to the necessity of rethinking diagnostic concepts and DSM diagnostic hierarchies.

Panikattacken mit frühem und spätem Beginn: Unterschiedliche pathogenetische Mechanismen? / Early- and Late-Onset Panic Attacks: Evidence for Different Pathogenic Mechanisms?Wittchen, Hans-Ulrich, Perkonigg, Axel 03 December 2012 (has links) (PDF)
Panikattacken sind mit einer Lebenszeitprävalenz von ungefähr 15% ein relativ häufiges Phänomen im Gegensatz zu einer vollen Panikstörung, die eine Prävalenz von 2,3–3% aufweist. In der vorliegenden epidemiologischen Untersuchung (n = 481) einer bundesweiten repräsentativen Stichprobe wurde geprüft, ob früh (vor dem 25. Lebensjahr) und spat auftretende Panikattacken sich hinsichtlich Symptomatik, Verlaufs- und Komorbiditätsmustern unterscheiden. Neben einer erhöhten Angstsymptomatik, insbesondere bezüglich respiratorischer Beschwerden und der Angst zu sterben, zeigte sich bei Panikattacken mit spätem Beginn ein erhöhtes Risiko für Multimorbidität. Auch entwickelten sich bei dieser Gruppe komorbide Bedingungen schneller. Dagegen waren Panikattacken mit frühem Beginn und einem erhöhten Risiko für Agoraphobie sowie phobische Störungen verbunden. Die Ergebnisse werden im Hinblick auf pathogenetische Mechanismen und Implikationen für die Planung therapeutischer Interventionen diskutiert.

Dynamics of Defensive Reactivity in Patients with Panic Disorder and Agoraphobia: Implications for the Etiology of Panic DisorderRichter, Jan, Hamm, Alfons O., Pané-Farré, Christiane A., Gerlach, Alexander L., Gloster, Andrew T., Wittchen, Hans-Ulrich, Lang, Thomas, Alpers, Georg W., Helbig-Lang, Sylvia, Deckert, Jürgen, Fydrich, Thomas, Fehm, Lydia, Ströhle, Andreas, Kircher, Tilo, Arolt, Volker 15 August 2013 (has links) (PDF)
Background: The learning perspective of panic disorder distinguishes between acute panic and anxious apprehension as distinct emotional states. Following animal models, these clinical entities reflect different stages of defensive reactivity depending upon the imminence of interoceptive or exteroceptive threat cues. The current study tested this model by investigating the dynamics of defensive reactivity in a large group of patients with panic disorder and agoraphobia (PD/AG).
Methods: Three hundred forty-five PD/AG patients participated in a standardized behavioral avoidance test (being entrapped in a small, dark chamber for 10 minutes). Defense reactivity was assessed measuring avoidance and escape behavior, self-reports of anxiety and panic symptoms, autonomic arousal (heart rate and skin conductance), and potentiation of the startle reflex before and during exposure of the behavioral avoidance test.
Results: Panic disorder and agoraphobia patients differed substantially in their defensive reactivity. While 31.6% of the patients showed strong anxious apprehension during this task (as indexed by increased reports of anxiety, elevated physiological arousal, and startle potentiation), 20.9% of the patients escaped from the test chamber. Active escape was initiated at the peak of the autonomic surge accompanied by an inhibition of the startle response as predicted by the animal model. These physiological responses resembled the pattern observed during the 34 reported panic attacks.
Conclusions: We found evidence that defensive reactivity in PD/AG patients is dynamically organized ranging from anxious apprehension to panic with increasing proximity of interoceptive threat. These data support the learning perspective of panic disorder.
