Panic Disorder


Panic disorder is a type of anxiety disorder characterized by recurrent and unpredictable bursts of terror known as panic attacks. A panic attack is accompanied by physical symptoms that may feel similar to a heart attack or other life-threatening condition. Intense anxiety often develops between episodes of panic. As panic attacks become more frequent, people begin avoiding situations that could trigger them. Panic attacks can lead to agoraphobia . This is a fear of being trapped in places or situations where escape could be difficult or impossible.


Panic disorder is likely to be an interaction of:
  • Genetics
  • Changes in brain function or metabolism
  • Psychosocial stressors that combine to influence the brain's fear networks

  • Increased sensitivity to physical sensations
