On the mental side it was clear that the man’s character had changed, according to information supplied by the mother. Aprosexia, impairment of memory, recollective and retentive, inability to give age, birth date and similar data. Words came with difficulty. Some disorder of comprehension; stereotyped replies; negativism; indifference; he would sit hours in a chair or on a bed silent and inactive. Fixed attitudes; dull glance; eyelids half closed. In short, it seemed as if this patient was a case of catatonic dementia praecox. _Re_ dementia praecox and shell-shock, Stansfield remarks upon the similarity of certain symptoms found in Shell-shock to those of dementia praecox; for example, apathy, retardation, amnesia and speech defect. According to Stansfield, one often gets the impression in a Shell-shock case as though the trench and shell fire stress had merely brought out a latent dementia praecox. _Re_ his new “sterno” sign (sternomastoid contraction on percussion of neck at level of third dorsal vertebra), Dupouy claims it negative in normal subjects, positive in concussion, meningitis, and general paresis. Shell-shock; fatigue; fugue; delusions. Recovery. =Case 162.= (ROUGE, 1915.) A sergeant, 40, had had nineteen years of service and had been married five months when he was recalled to the colors when war broke out, and sent to the front. March, 1915, he was exposed to bomb explosions during a very intense bombardment. He then got into the way of saying that he was akin to everybody. April 20, he was evacuated on the score of general fatigue, rejoined the company May 17, left his comrades at the end of June, and was taken up as a deserter by the police, who, observing his state, brought him to a hospital. He there showed “cerebral overexcitement” with “incoherence and nervousness.” In two or three days he was much better. He was evacuated on the sixth day to the hospital at Vichy. There was amnesia for the fugue and he could remember no further back than the extraction of a tooth at the Vichy hospital. In fact, he attributed the fugue to this dental operation. His wife took him home, but he soon threatened her with a revolver; got better in the night and next day went about apparently normal, buying things, however, extravagantly. His delusional state began once more, and two days later he was brought to Limoux. It seems that, while in Mauretania, he had formerly shown signs of mental disorder, having a mania for wireless and airplane inventions and the like. A cousin-german had also been in a hospital for the insane twice, recovering each time. There was a lingual and manual tremor. The man had not been recently alcoholic. He was a little irritable and showed a little megalomania, but worked hard and made himself useful. He went out, recovered, November 12, 1915.
