Concept:
Panic Disorder is a type of anxiety disorder in which a person experiences repeated panic attacks. A panic attack is a sudden period of intense fear or discomfort accompanied by physical and emotional symptoms such as rapid heartbeat, sweating, trembling, dizziness, breathlessness, chest pain, and fear of dying or losing control.
