Clinical Information
  • A category of psychiatric disorders which are characterized by emotional or behavioral symptoms that develop within 3 months of a stressor and do not persist for more than an additional 6 months after the stressor is no longer present.
  • A condition in which a person responds to a stressful event (such as an illness, job loss, or divorce) with extreme emotions and actions that cause problems at work and home.
  • Maladaptive reaction to psychosocial stressors which impairs social or occupational functioning. Usually a temporary condition that remits after new levels of adaptation are obtained or stressors have been removed.
  • Maladaptive reactions to identifiable psychosocial stressors occurring within a short time after onset of the stressor. They are manifested by either impairment in social or occupational functioning or by symptoms (depression, anxiety, etc.) that are in excess of a normal and expected reaction to the stressor.
