This article examines the theories of anxiety on the chemical and defense system of the body. Anxiety is actually experienced by all people. Anxiety is a diffuse, very unpleasant, and often vague feeling that is often accompanied by symptoms of autonomic system such as chest tightness, palpitations, sweating, headache, brief stomach discomfort, and restlessness characterized by inability to sit or stand. The total number of symptoms that exist during anxiety is different between people. The classification of anxiety disorders in psychology is justified by many obstacles, which are on the one hand, due to the gradual formation of the personality structure in the periods of transformation and the importance of communication issues in these periods, and on the other hand, they originate from the disagreement of different authors about the scope of anxiety disorders. Currently, due to the existence of such problems and despite the existence of different classifications, a specific classification approved by all psychologists and psychiatrists, that is, can cover the realm of anxiety disorders during the transformation period, avoid the risk of ignoring an anxiety disorder and it is not possible to investigate the risk factors and how the disorders evolve, and also to enable the correct evaluation of psychotherapy methods.
