Neuroses are defined as conditions of disturbed physiological balance of the body. Abnormal tension arises and, because of the spurious goals of the neurotic, a permanent state of excitation develops. Autonomic stimulation and widespread physiological changes result from this condition in which tension is not used for goal directed strivings as in the healthy individual. Treatment aims at a reorganization which, through the development of new techniques in interpersonal relationships, will permit a satisfactory fulfilment of needs.
