Anxiety is a normal human emotion that everyone experiences at times. Many people feel anxious, or nervous, when faced with a problem at work, before taking a test, or making an important decision. Anxiety disorders, however, are different. They can cause such distress that it interferes with a person's ability to lead a normal life. An anxiety disorder is a serious mental illness.
The source of many anxiety disorders is a conditioned fear. We speak of a conditioned fear when an object or situation that in itself is neutral becomes associated with something that is threatening , thus triggering a fear reaction. The various anxiety disorders involve many different areas of the brain. These areas reflect both the uniqueness of each of these disorders and the features that they have in common. The amygdala, for example, plays a central role in anxiety disorders. This structure in the warns us when a danger is present in our environment and triggers the fear reaction and then the fight or flight reaction to get us out of it.
