Agoraphobia

Agoraphobia (from Greek ἀγορά, "marketplace"; and φόβος/φοβία, -phobia) is an anxiety disorder characterized by anxiety in situations where the sufferer perceives the environment as being difficult to escape or get help. These situations include, but are not limited to, wide-open spaces, as well as uncontrollable social situations such as may be met in shopping malls, airports, and on bridges. Agoraphobia is defined within the DSM-IV TR as a subset of panic disorder, involving the fear of incurring a panic attack in those environments. The sufferer may go to great lengths to avoid those situations, in severe cases becoming unable to leave their home or safe haven.
