WITH THE END OF THE WAR an apt occasion is offered for a survey of work done, so that we may mobilize our ideas to attack the problem of neuroses in peace. Neuroses of war have been referred to by the term “shell-shock.” It is almost universally agreed by neurologists that this is a bad term, more borne in on us to-day, when shells are a thing of the past. Neuroses of war are essentially similar to the neuroses of peace, dependent on the same mechanisms and amenable to the same treatment. Three groups of cases seem to stand out: neuroasthenia; hysteria; and neuroses dependent on the occurrence of mental conflicts.
