Agoraphobia, as described in this manner, is actually a symptom professionals check when making a diagnosis of panic disorder. Other syndromes like obsessive compulsive disorder or post-traumatic stress disorder can also cause agoraphobia. Essentially, any irrational fear that keeps one from going outside can cause the syndrome.People with agoraphobia may experience temporary separation anxiety disorder when certain other individuals of the household depart from the residence temporarily, such as a parent or spouse, or when they are left home alone. Such temporary conditions can result in an increase in anxiety or a panic attack or feeling the need to separate themselves from family or maybe friends.People with agoraphobia sometimes fear waiting outside for long periods of time; that symptom can be called "macrophobia". Panic attacks
Agoraphobia patients can experience sudden panic attacks when traveling to places where they fear they are out of control, help would be difficult to obtain, or they could be embarrassed. During a panic attack, epinephrine is released in large amounts, triggering the bodys natural fight-or-flight response. A panic attack typically has an abrupt onset, building to maximum intensity within 10 to 15 minutes, and rarely lasts longer than 30 minutes. Symptoms of a panic attack include palpitations, rapid heartbeat, sweating, trembling, nausea, vomiting, dizziness, tightness in the throat, and shortness of breath. Many patients report a fear of dying, fear of losing control of emotions, or fear of losing control of behaviors. Causes
Agoraphobia is believed to be due to a combination of genetic and environmental factors.
Self-medication or a combination of factors may also explain the association between tobacco smoking and agoraphobia and panic. Attachment theory
Some scholars have explained agoraphobia as an attachment deficit, i.e., the temporary loss of the ability to tolerate spatial separations from a secure base. Recent empirical research has also linked attachment and spatial theories of agoraphobia. Spatial theory
In the social sciences, a perceived clinical bias exists in agoraphobia research. Branches of the social sciences, especially geography, have increasingly become interested in what may be thought of as a spatial phenomenon. One such approach links the development of agoraphobia with modernity. Factors considered contributing to agoraphobia within modernity are the ubiquity of cars and urbanization. These have helped develop the expansion of public space and the contraction of private space, thus creating in the minds of agoraphobia-prone people a tense, unbridgeable gulf between the two. Evolutionary psychology
An evolutionary psychology view is that the more unusual primary agoraphobia without panic attacks may be due to a different mechanism from agoraphobia with panic attacks. Primary agoraphobia without panic attacks may be a specific phobia explained by it once having been evolutionarily advantageous to avoid exposed, large, open spaces without cover or concealment. Agoraphobia with panic attacks may be an avoidance response secondary to the panic attacks, due to fear of the situations in which the panic attacks occurred. Diagnosis
Most people who present to mental health specialists develop agoraphobia after the onset of panic disorder.
