The aim of this study was to prospectively examine the 10-year natural course of panic attacks (PA), panic disorder (PD) and agoraphobia (AG) in the first three decades of life, their stability and their reciprocal transitions.
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. At the end of the study, 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.
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. 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.
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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
