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.
Although obsessive compulsive disorder (OCD) is a common disorder (seen at a rate of 1.6-2.2 % in the general population), for various reasons its diagnosis is usually delayed.
What is a psychological trauma? What is meant by psychological trauma is an event significant enough to inflict emotional damage on anyone who is exposed to it. We can list some of the traumas created by men as follows: war, physical or sexual assault, serious accidents, being a witness to harm inflicted to oneself or someone else. Some traumatic events are caused by nature, like fires, earthquakes, storms and floods.
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.
