Agoraphobia is the most common type of phobia, and it is estimated to affect between 5-12% of Americans within their lifetime. Agoraphobia is twice as common in women as in men and usually strikes between the ages of 15-35.
The symptoms of the panic attacks which may accompany agoraphobia vary from person to person, and may include trembling, sweating, heart palpitations (a feeling of the heart pounding against the chest), jitters, fatigue, tingling in the hands and feet, nausea, a rapid pulse or breathing rate, and a sense of impending doom.
Agoraphobia and other phobias are thought to be the result of a number of physical and environmental factors. For instance, they have been associated with biochemical imbalances, especially related to certain neurotransmitters (chemical nerve messengers) in the brain. People who have a panic attack in a given situation (e.g., a shopping mall) may begin to associate the panic with that situation and learn to avoid it. According to some theories, irrational anxiety results from unresolved emotional conflicts. All of these factors may play a role to varying extents in different cases of agoraphobia.
