Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. People experiencing a panic attack may believe they are having a heart attack or they are dying or going crazy.
The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them.
Most people with panic attacks experience several of the following symptoms:
Feeling weak, faint, or dizzy
Tingling or numbness in the hands and fingers
Sense of terror, or impending doom or death
Feeling sweaty or having chills
Feeling a loss of control
Panic attacks are generally brief, lasting less than 10 minutes, although some of the symptoms may persist for a longer time. People who have had one panic attack are at greater risk for having subsequent panic attacks than those who have never experienced a panic attack. When the attacks occur repeatedly, and there is worry about having more episodes, a person is considered to have a condition known as panic disorder.
People with panic disorder may be extremely anxious and fearful, since they are unable to predict when the next episode will occur. Panic disorder is fairly common and affects about 6 million adults in the U.S. Women are twice as likely as men to develop the condition, and its symptoms usually begin in early adulthood.
It is not clear what causes panic disorder. In many people who have the biological vulnerability to panic attacks, they may develop in association with major life changes (such as getting married, having a child, starting a first job, etc.) and major lifestyle stressors. There is also some evidence that suggests that the tendency to develop panic disorder may run in families. People who suffer from panic disorder are also more likely than others to suffer from depression, attempt suicide, or to abuse alcohol or drugs.
