Upon recovery of consciousness, which may take place after periods varying between a few minutes and a few weeks, the immediate disorders of sensation, emotion, intellect, and movement, are often very severe. It may be presumed that at the beginning of the war they must have appeared far more serious to most of the doctors who saw them in their early stages than they would now. This speculation is suggested by the evidence of the case-sheets sent with the men from France in the early period of the campaign. Such diagnoses as “delusional insanity,” and other similar terms taken from the current classifications of advanced conditions of insanity, appear very frequently as descriptions of cases which on arrival in England had almost entirely lost every sign of mental unusualness. In fact, one of the most cheering aspects of work amongst this type of case has been the rapidity with which men who have presented quite alarming symptoms have subsequently recovered. It may seem almost unnecessary to enumerate the bizarre phenomena which constitute the immediate results of shell-shock, for our newspapers have naturally seized upon such unusual details and have made the most of their opportunities in this direction. But the reader will obtain a clearer idea of the facts if they are catalogued once more. The most obvious phenomena are undoubtedly the disturbances of sensation and movement. A soldier may be struck blind, deaf or dumb by a bursting shell: in rare cases he may exhibit all three disorders simultaneously or even successively. It should be added that these troubles often vanish after a short space of time, as suddenly and dramatically as they appeared. Thus one of the blinded soldier survivors of the _Hesperian_ recovered his sight on being thrown into the water. Other blind patients have had their sight restored under the action of hypnosis. Mutism is often conquered by the shock of a violent emotion, produced accidentally or purposely. Examples of such “shocking” events taken at random from our experience were the sight of another patient slipping from the arms of an orderly, the “going under” chloroform, the application of a faradic current to the neck, the announcement at a “picture house” of Rumania’s entry into the war (this cured two cases simultaneously), and the sight of the antics of our most popular film comedian. The latter agency cured a case of functional deaf-mutism, the patient’s first auditory sensations being the sound of his own laugh.
