Understanding and Overcoming Anxiety Disorders
Introduction
What is Anxiety Disorder?
Anxiety is a normal reaction to stress and can be beneficial in some situations. It can alert us to dangers and help us prepare and pay attention.
Anxiety disorders differ from normal feelings of nervousness or anxiousness and involve excessive fear or anxiety. Along with depression, anxiety disorders are the most common of mental disorders and affect more than 25 million Americans.
Anxiety Disorders, include disorders that share features of excessive fear and anxiety and related behavioural disturbances. Fear is the emotional response to real or perceived imminent threat, whereas anxiety is anticipation of future threat.
It is evident that these two states overlap, nevertheless they also differ, as fear is more often associated with surges of autonomic arousal necessary for fight or flight, thoughts of immediate danger, and escape behaviours, while anxiety is more often associated with muscle tension and vigilance in preparation for future danger and cautious or avoidant behaviours.
