Agoraphobia is an anxiety disorder which primarily consists of the fear of experiencing a difficult or embarrassing situation from which the sufferer cannot escape. As a result, severe sufferers of agoraphobia may become confined to their homes, experiencing difficulty traveling from this "safe place."

[edit] Definition
The word "agoraphobia" is an English adoption of the Greek words agora (αγορά) and phobos (φόβος), literally translated as "a fear of the marketplace." This translation is the reason for the common misconception that agoraphobia is a fear of open spaces, and is not clinically accurate.
Agoraphobics are not necessarily afraid of open spaces themselves, but more generally suffer panic attacks in response to the idea of being in an embarrassing or difficult situation where they are exposed to the world with no escape route, and no certainty of reassurance and help.[1]
People with agoraphobia may experience panic attacks in situations where they feel trapped, insecure, out of control, or too far from their personal comfort zone. In severe cases, an agoraphobic may be confined to their home. [2] Some people with agoraphobia are comfortable seeing visitors, but only in a defined space they feel in control of. Such people may live for years without leaving their homes, while happily seeing visitors and working, as long as they can stay within their safety zones. The safety zones can vary, from not being able to leave home, or not being able to make eye contact. If the person leaves their 'safety zone' they can have an anxiety attack.
[edit] Prevalence
The one-year prevalence of agoraphobia is about 5 percent. [3] About one third of people with Panic Disorder progress to develop Agoraphobia. [4] Agoraphobia occurs about twice as commonly among women as it does in men (Magee et al., 1996[5]). The gender difference may be attributable to social/cultural factors that encourage, or permit, the greater expression of avoidant coping strategies by women (DSM-IV), or dissuade men from seeking help and reporting the onset of agoraphobia.
[edit] Diagnosis
Most people who present to mental health specialists develop agoraphobia after the onset of panic disorder (American Psychiatric Association, 1998). Agoraphobia is best understood as an adverse behavioral outcome of repeated panic attacks and the subsequent worry, preoccupation, and avoidance.[6] Thus, the formal diagnosis of panic disorder with agoraphobia was established. However, for those people in communities or clinical settings who do not meet full criteria for panic disorder, the formal diagnosis of Agoraphobia Without History of Panic Disorder is used (DSM-IV).
[edit] Association with panic attacks
Agoraphobia patients can experience sudden panic attacks when traveling to places where they fear, where help would be difficult to obtain. During a panic attack, adrenaline is released in large amounts for several minutes causing the classical "fight or flight" condition. The attack typically has an abrupt onset, building to maximum intensity within 10 to 15 minutes, and rarely lasts longer than 30 minutes. [7] These symptoms include palpitations, sweating, trembling, and shortness of breath. Many patients report a fear of dying, or losing control of emotions or behavior. [7]
[edit] Treatments
Agoraphobia can be successfully treated in many cases through a very gradual process of graduated exposure therapy combined with cognitive therapy and sometimes anti-anxiety or antidepressant medications. Treatment options for agoraphobia and panic disorder are similar.
Exposure treatment can provide lasting relief to the majority of patients with panic disorder and agoraphobia. Disappearance of residual and subclinical agoraphobic avoidance, and not simply of panic attacks, should be the aim of exposure therapy. [8]
Anti-anxiety medications include benzodiazepines such as alprazolam. Anti-depressant medications which are used to treat anxiety disorders are mainly in the SSRI (selective serotonin reuptake inhibitor) class such as sertraline, paroxetine and fluoxetine. Hypnosis is a possible alternative treatment. [citation needed]
[edit] Alternate theories
[edit] Attachment theory
Some scholars (e.g., Liotti 1996,[9] Bowlby 1998[10]) have explained agoraphobia as an attachment deficit, i.e., the temporary loss of the ability to tolerate spatial separations from a secure base.
[edit] Spatial theory
In the social sciences there is a perceived clinical bias (e.g., Davidson 2003[11]) in agoraphobia research. Branches of the social sciences, especially geography, have increasingly become interested in what may be thought of as a spatial phenomenon.
