The lexical meaning of anxiety is the sensation of fear or panic. Possible to be experienced by all in daily life, this sensation is frequent and constant in generalized anxiety disorder (GAD).
Anxiety (worries, concerns, distress) is normally a necessary part of human nature, in that it acts as a signal indicating that internal demands are waiting to be satisfied. There are many internal demands like hunger, thirst, sex etc. The body expects these to be satisfied there and then. In reality however the external world generally does not allow this to happen. In such a situation we experience anxiety. We have a series of defence mechanisms that come into play, starting from denying the presence of the stimulus all the way to ridiculing it. If the defence mechanisms prove insufficient then psychiatric disorders can set in. One of these is generalized anxiety disorder.
In this article, the recent studies made on panic disorders are summarized. The age range where panic disorder is observed the most is 20-29, and it was founded that the rate of prevalence in women of these ages is two times higher than that of men.
Anxiety, which can be described as a state of excessive worry, apprehension and restlessness, is one of the states most commonly experienced by people. When confronted with a threat, people feel a high level of apprehension. At the same time fight or flight reactions set in when the nervous system is strongly stimulated. These establish themselves as sweating, shivering, hot flushes, numbness, palpitations, a feeling of suffocation, alienation. They are produced by the sympathetic nervous system whose task is to deal with danger.
People with social anxiety disorder believe that in social situations they are being looked at, scrutinized and judged by other people. This produces great anxiety in the sufferers of social anxiety disorder. They try and avoid such environments, and if they cannot avoid them they refrain from participating in conversations and, for example, prefer to sit in a corner where they are least likely to draw attention to themselves. Even the thought of being in a social situation makes them anxious. Some people only become anxious in particular situations, like talking, writing, or playing an instrument in front of a crowd. Others experience anxiety in almost all social situations and environments like a restaurant, canteen, seminar room or a friends gathering, where they feel they are being looked at.
