Agoraphobia is classified as an anxiety disorder, often brought about by the fear of suffering from a panic attack in a setting from which there is no straitforward escape route. As a result, agoraphobic individuals tend to avoid public or strange places. The most acute cases of agoraphobia will cause the sufferer to become imprisoned in their home and will lead to difficulty leaving this "safe place."

This type of anxiety may be set in motion by open spaces, crowds, or traveling (even small journeys). Fear of social embarrassment plays a significant role for those who suffer from this form of panic disorder, as the individual may dread the possible onset of panic and worry about appearing troubled in front of onlookers.

Most people who talk to health care professionals have developed agoraphobia having previously suffered from panic disorder. Agoraphobia is perhaps most clearly understood as an negative outcome upon an individuals behavior resulting from repeated panic attacks. This change in behaviour might manifest itself as an avoidence of certain situations, people or places that the individual associates with a previous onset of panic.

Treatment options for agoraphobia and panic disorder are not dissimilar. Anti-depressent or anti-anxiety medications may be used along with gradual exposure treatments and cognitive behavioural therapy.

Relaxation techniques are recommended skills that the agoraphobia sufferer can learn, as they can help to lessen or even stop the symptoms of anxiety and panic disorder.

Many people with anxiety disorders find some relief by joining a support group and discussing their problems and accomplishments with other sufferers. There is evidence that aerobic exercise may also have a calming effect. Although, the fears that may be associated with these types of activity may have to be overcome before participation is possible.
