SOMATOFORM DISORDERS:

The term 'Neurosis'  was first introduced in 1769 by William Cullen (1710-  1790). Till later part of nineteenth century, anxiety disorders were conspicuously missing from the  classification of psychiatric disorder. Mayer (1  886-1950) included in his nomenclature a separate description of neurosis, psychoses, affective states, organic braindisease  and sub normality.  

Sigmud Freud (1841- 1925) developed a classification of neuroses; and his concepts of neuroses have formed the foundation of psychoanalytical thought. 

Neurosis may be defined as a mild to moderately severe illness in the personality in which the ego  function of reality-testing  is greatly impaired, and in which the maladjustment  to life is relatively limited.
