The feared object/situation is avoided or endured with intense anxiety or distress. The avoidance, anticipation of, or distress of the phobic object/situation must cause significant distress or interferes with the individual's daily life, occupational, academic, or social functioning to meet diagnosis. The symptoms cannot be better accounted for by another mental disorder or be caused by substances, medications, or medical illness.
Once someone has had a panic attack, he or she may develop irrational fears, called phobias, about the situations they are in during the attacks and begin to avoid them. That, in turn, may reach the point where the mere idea of doing things that preceded the first panic attack triggers terror or dread of future panic attacks, resulting in the individual with panic disorder being unable to drive or even step out of the house. If this occurs, the person is considered to have panic disorder with agoraphobia.
In deeper level psychoanalytic approaches, in particular object relations theory, panic attacks are frequently associated with splitting (psychology), paranoid-schizoid and depressive positions, and paranoid anxiety. They are often found comorbid with borderline personality disorder and child sexual abuse. Paranoid anxiety may reach the level of a persecutory anxiety state.
When the medical personnel take my vitals, my heart rate has soared above 136 and my breathing is rapid and short. The sweating has slowed, but I am nauseous and dry heaving. It takes about 30 minutes for the aides to update my stats and explain that they think I may be having a minor heart attack or have blood clots going to my heart. They say I need to get to a hospital.
People with panic disorder often worry about when the next attack will happen and actively try to prevent future attacks by avoiding places, situations, or behaviors they associate with panic attacks. Worry about panic attacks, and the effort spent trying to avoid attacks, cause significant problems in various areas of the person’s life, including the development of agoraphobia (see below).
