Battles (including liquid fire); eventually shell-shock: Hallucinatory delirium, mutism, asthenia—after a few days puerilism (history of convulsive crisis in adolescence) with regression of personality to late childhood.
Puerilism (Dupré) appeared in a soldier, 21 (uncle and cousin insane; patient had difficulty in studies at fourteen and nervous spells for two years, with loss of consciousness, fall and convulsions probably at rare intervals; a student at eighteen) after he had taken part in a number of battles with the Chasseurs Alpins. He was exposed once to liquid fire July 21, 1916. He entered the military psychiatric center at Amiens. Mental troubles had followed the bursting of a shell near him. He said a few words, such as, “Alsace; fire; blood; snow; it hurts.” These phrases, spoken in a low tone, with an anxious appearance, eyes fixed, suggested hallucination. He seemed to be listening. Aside from the isolated words above mentioned he showed complete mutism. There was physical weakness, difficulty in walking without support, exaggeration of patellar reflexes, pains in the head and limbs. After several days, he said, “Milk; bread.” After this the anxiety and the slow and difficult walking disappeared, whereupon the puerilism appeared.
Now the soldier began to run instead of walking. He galloped and gamboled like a child imitating a horse, or he would sit on a board seeming to paddle. He would skip along the halls. The puerilistic phases were rather brief and for the most part he lay in bed. There was still a certain asthenia. He made little paper boats in bed, keeping them in a small metal box along with bits of bread, looking glass and the like. If a gesture was made to take them away, he would protest and press the box to his breast, looking childish and anxious, and if the box were taken he would weep hot tears. Sometimes he would stick out his tongue at the attendants. His mother came to see him and afterwards he would say, “Mamma told me to be good, to eat well, to get well and to go home.” He would use childish grammar,—“Me eat much.” Asked why he had hollowed out a small hole in the wall of the room, he answered, “I did it for fun, but I will not do it any more. Mother doesn’t want me to.” The patient was unwilling to answer a question correctly; would sometimes answer incorrectly at first and correctly afterward.
It appears that the man had adopted the language, occupations and attitude of a child, showing a regression of personality ten to twelve years backwards. There was a neurotic basis in the convulsive crises of adolescence. On the basis of this predisposition following shock there appeared an attack of confusion, upon which, several days later, supervened ecmnesic phenomena of hysterical nature assuming all the features of puerilism.
