A study of the incidence of 'somatization reactions' in five hundred eighty-five unselected and successive cases of psychoneurosis showed that one hundred fifty-nine cases (27 per cent) revealed organ dysfunction as a secondary disorder.

'Somatization' is a term adopted by the U. S. Army to cover disorders which 'probably' result from the channeling of psychopathological impulses through the autonomic nervous system into the viscera with resultant dysfunction.

The reactions covered in the survey include psychogenic gastrointestinal, cardiovascular, genito-urinary, allergic, skin, asthenic and rheumatic reactions. No attempt is made to describe these disorders in further detail or to present individual cases.

The conclusion is reached that orientation of the general practitioner in the psychoneurotic approach is necessary because of the high per cent of psychoneurotic cases with organ dysfunctions who will first consult the nonpsychiatric physician.
