Acute Stress Reaction
A transient disorder of significant severity, which develops in an individual without any previous mental disorder in response to exceptional physical and/or psychological stress.
Not all people exposed to the same stressful event develop the disorder.
The symptoms: 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 (extreme variant - dissociative stupor), or by agitation and overactivity.
Autonomic signs - tachycardia, sweating or flushing, as well as other anxiety or depressive symptoms.
The symptoms usually appear within minutes of the impact of the stressful event, and disappear within several hours, maximally 2—3 days.
