Panic disorder is a diagnosis given to people who experience recurrent unexpected panic attacks— that is, the attack appears to occur from out of the blue. The term recurrent refers to the fact that the individual has had more than one unexpected panic attack. In contrast, expected panic attacks occur when there is an obvious cue or trigger, such as a specific phobia or generalized anxiety disorder. In the U.S., roughly 50% of people with panic disorder experience both unexpected and expected panic attacks.
Not everyone who worries a lot has an anxiety disorder. You may be anxious because of an overly demanding schedule, lack of exercise or sleep, pressure at home or work, or even from too much caffeine. The bottom line is that if your lifestyle is unhealthy and stressful, you’re more likely to feel anxious—whether or not you actually have an anxiety disorder. These tips can help to lower anxiety and manage symptoms of an anxiety disorder:
There are also things that people with panic disorder can do to learn how to handle it and to make treatment more effective. Since substances like drinking alcohol or caffeinated beverages, or using illicit drugs can worsen panic attacks, those things should be avoided. Other tips to prevent or manage panic attacks include engaging in aerobic exercise and stress-management techniques like deep breathing, massage therapy, and yoga, since these self-help activities have also been found to help decrease the frequency and severity of panic attacks. Although many people use home remedies like breathing into a paper bag when afflicted by the hyperventilation that can be associated with panic, the benefit received may be the result of the individual believing it will remedy the symptoms (placebo effect). Also, breathing into a paper bag when one is already having trouble breathing can make matters worse when the hyperventilation is the result of conditions of oxygen deprivation, like an asthma attack or a heart attack.
People with panic attacks often report a fear of dying or heart attack, flashing vision, faintness or nausea, numbness throughout the body, heavy breathing and hyperventilation, or loss of body control. Some people also suffer from tunnel vision, mostly due to blood flow leaving the head to more critical parts of the body in defense. These feelings may provoke a strong urge to escape or flee the place where the attack began (a consequence of the "fight-or-flight response", in which the hormone causing this response is released in significant amounts). This response floods the body with hormones, particularly epinephrine (adrenaline), which aid it in defending against harm.
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).
