General Adaptation syndrome is seen in?

Option A: Depression
Option B: Anxiety
Option C: Panic attack
Option D: Stressful situation

The correct answer is D. Stressful situation.

  • Hans Selye developed a model of stress that he called the general adaptation syndrome. 
  • It consisted of three phases: (1) the alarm reaction; (2) the stage of resistance, in which adaptation is ideally achieved; and (3) the stage of exhaustion, in which acquired adaptation or resistance may be lost. 
  • He considered stress a nonspecific bodily response to any demand caused by either pleasant or unpleasant conditions. 
  • Selye believed that stress, by definition, need not always be unpleasant. He called unpleasant stress distress while pleasent stress eustress. Accepting both types of stress requires adaptation. 
  • The body reacts to stress defined as anything (real, symbolic, or imagined) that threatens an individual's survival by putting into motion a set of responses that seeks to diminish the impact of the stressor and restore homeostasis. 
  • Many stressors occur over a prolonged period of time or have long-lasting repercussions. For example, the loss of a spouse may be followed by months or years of loneliness and a violent sexual assault may be followed by years of apprehension and worry. Neuroendocrine and immune responses to such events help explain why and how stress can have deleterious effects.
