Acute stress disorder

Acute Stress Disorder is characterized by the development of severe anxiety, dissociative, and other symptoms that
occurs within one month after exposure to an extreme traumatic stressor (e.g., witnessing a death or serious accident).
As a response to the traumatic event, the individual develops dissociative symptoms. Individuals with Acute Stress
Disorder have a decrease in emotional responsiveness, often finding it difficult or impossible to experience pleasure in
previously enjoyable activities, and frequently feel guilty about pursuing usual life tasks.
