People with panic disorder have sudden and repeated attacks of fear that last for several minutes or longer. These are called panic attacks. 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 school or work, going to the grocery store, or driving.
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.
What causes Panic Disorder?
Panic disorder sometimes runs in families, but no one knows for sure why some family members have it while others don’t. Researchers have found that several parts of the brain, as well as biological processes, play a key role in fear and anxiety. Some researchers think that people with panic disorder misinterpret harmless bodily sensations as threats. By learning more about how the brain and body functions in people with panic disorder, scientists may be able to create better treatments. Researchers are also looking for ways in which stress and environmental factors may play a role.
