“I thought I was having a heart attack.” “I was afraid I was dying.” “I could not calm down.” Often these feelings are the reason people seek help. Usually the first stop is the Emergency Room, where, if no medical condition can be determined, panic attack or panic disorder may be diagnosed. The latest psychiatric diagnostic manual describes a panic attack as including a number of behaviors that differ significantly from usual behavior. Seeming to come out of nowhere, “intense fear or intense discomfort reaches a peak within minutes” and can last anywhere from a few minutes to an hour or more. The attack is often characterized by chest pain, shortness of breath, clamminess, fear of dying, light-headedness, numbness or tingling and nausea. A pattern of such episodes is diagnosed as panic disorder. A key aspect of panic disorder is the anticipation of further attacks, which can lead to a restricted life style designed to avoid another episode. Many effective treatments are available for panic disorder. They include psychotherapy, medication and cognitive behavior therapy. These approaches are often combined to ensure a more successful outcome.
