vibrating stress

Definition: This category differs from others in that it includes disorders identifiable on the basis of not only symptoms and course but also the existence of one or other of two causative influences: an exceptionally stressful life event producing an acute stress reaction, or a significant life change leading to continued unpleasant circumstances that result in an adjustment disorder. Although less severe psychosocial stress ( life events ) may precipitate the onset or contribute to the presentation of a very wide range of disorders classified elsewhere in this chapter, its etiological importance is not always clear and in each case wi ...[+++]ll be found to depend on individual, often idiosyncratic, vulnerability, i.e. the life events are neither necessary nor sufficient to explain the occurrence and form of the disorder. In contrast, the disorders brought together here are thought to arise always as a direct consequence of acute severe stress or continued trauma. The stressful events or the continuing unpleasant circumstances are the primary and overriding causal factor and the disorder would not have occurred without their impact. The disorders in this section can thus be regarded as maladaptive responses to severe or continued stress, in that they interfere with successful coping mechanisms and therefore lead to problems of social functioning.

Definition: A transient disorder that develops in an individual without any other apparent mental disorder in response to exceptional physical and mental stress and that usually subsides within hours or days. Individual vulnerability and coping capacity play a role in the occurrence and severity of acute stress reactions. The symptoms show a typically mixed and changing picture and include an initial state of daze with some constriction of the field of consciousness and narrowing of attention, inability to comprehend stimuli, and disorientation. This state may be followed either by further withdrawal from the surrounding ...[+++]situation (to the extent of a dissociative stupor - F44.2), or by agitation and over-activity (flight reaction or fugue). Autonomic signs of panic anxiety (tachycardia, sweating, flushing) are commonly present. The symptoms usually appear within minutes of the impact of the stressful stimulus or event, and disappear within two to three days (often within hours). Partial or complete amnesia (F44.0) for the episode may be present. If the symptoms persist, a change in diagnosis should be considered. | Acute:crisis reaction | reaction to stress | Combat fatigue Crisis state Psychic shock

Definition: Enduring personality change, present for at least two years, following exposure to catastrophic stress. The stress must be so extreme that it is not necessary to consider personal vulnerability in order to explain its profound effect on the personality. The disorder is characterized by a hostile or distrustful attitude toward the world, social withdrawal, feelings of emptiness or hopelessness, a chronic feeling of being on edge as if constantly threatened, and estrangement. Post-traumatic stress disorder (F43.1) may precede this type of personality change. | Personality change after:concentration camp experiences | disasters ...[+++]| prolonged:captivity with an imminent possibility of being killed | exposure to life-threatening situations such as being a victim of terrorism | torture

Emphasises that innovative solutions to reduce noise from all transport modes, in particular at the source, are urgently needed in order to protect the health and quality of life of EU citizens and ensure acceptance among the population; recalls emphatically, in this context, its resolution on a Single European Transport Area, which called for the reduction by 2020 of noise and vibrations from, and energy consumption of, rail vehicles by 20 % relative to the reference values for 2010, and stresses once again that noise emissions ...[+++]should, from the outset, play a prominent part in the development of new technologies, strategies and infrastructure in the field of transport;
