People with panic disorder have sudden and repeated attacks of fear that last for several minutes or longer. Panic attacks are characterized by a fear of disaster or of losing control even when there is no real danger. A person may also have a strong physical reaction during a panic attack. It may feel like having a heart attack. Panic attacks can occur at any time, and many people with panic disorder worry about and dread the possibility of having another attack.

A person with panic disorder may become discouraged and feel ashamed because he or she cannot carry out normal routines like going to the grocery store or driving. Having panic disorder can also interfere with school or work.

Panic disorder often begins in the late teens or early adulthood. More women than men have panic disorder. But not everyone who experiences panic attacks will develop panic disorder.

The signs and symptoms of a panic attack develop abruptly and usually reach their peak within 10 minutes. Most panic attacks end within 20 to 30 minutes, and they rarely last more than an hour.

A full-blown panic attack includes a combination of the following signs and symptoms:

• Shortness of breath or hyperventilation
• Heart palpitations or a racing heart
• Chest pain or discomfort
• Trembling or shaking
• Choking feeling
• Feeling unreal or detached from your surroundings
• Sweating
• Nausea or upset stomach
• Feeling dizzy, light-headed, or faint
• Numbness or tingling sensations
• Hot or cold flashes
• Fear of dying, losing control, or going crazy

You may be suffering from panic disorder if you:

• Experience frequent, unexpected panic attacks that aren’t tied to a specific situation
• Worry a lot about having another panic attack
• Are behaving differently because of the panic attacks, such as avoiding places where you’ve previously panicked

Panic disorder sometimes runs in families, but no one knows for sure why some people have it while others don't. Researchers have found that several parts of the brain are involved in fear and anxiety. By learning more about fear and anxiety in the brain, scientists may be able to create better treatments. Researchers are also looking for ways in which stress and environmental factors may play a role.

Treatment can help reduce the intensity and frequency of your panic attacks and improve your function in daily life. The main treatment options are psychotherapy and medications. One or both types of treatment may be recommended, depending on a person's preference, their history, the severity of their panic disorder and whether they have access to therapists who have special training in treating panic disorders.
