Experience of the author indicates that the psychologic mechanism in cases of "war neurosis" is much simpler than that operative in the usual neurosis. It is comparatively easy in the former cases to treat the outstanding symptoms. Also at the conclusion of the last war, the symptoms usually disappeared in these cases. "We are dealing in these cases, not with real neurosis in which maladjustment of the personality is the central factor, but with direct consequences of the overwhelming conditions[long dash]reactions having adaptive protective value." The inner conflict is the essential element in ordinary neurosis, whereas the war neurosis is the result of the presence of unusual dangers and the difficulty or impossibility of the individual''s adjusting to them. The anxiety states observed in war are acute conditions of catastrophe that show the direct reactions to the situations of danger and that clear up if the latter are eliminated. Personality change need not necessarily develop. The conversion states observed in war are more similar to neurosis in that more escape mechanisms are developed as protection against danger and anxiety. But, again, the patient''s personality need not change deeply or permanently, and the mechanisms are usually discarded when the individual regains security. This results in a disappearance of the symptoms. The author concludes that "we should not speak of war neuroses but of anxiety states and conversional states due to war situations.".
