Shell-shock dementia praecox.
Case 161. (Dupuoy, 1916.)
A machine gunner, 23, was the sole survivor, March 18, 1915, of the explosion of a large calibre shell in a block house containing ten men. He worked himself out of the débris and came to Dupuoy’s attention in September, when an extension of leave was asked for him.
There were two groups of symptoms; persistent headache, painful hyperacousia, vertigo, tremulous walk, cervical spinal column stiff and painful both spontaneously and to pressure, muscular weakness, tremor of hands, hypesthesia of extremities especially upper, exaggeration of tendon and bone reflexes with tendency to ankle clonus and patellar clonus, sterno sign lively, frequent nosebleeds (two to four times a week), profound sweating, unequal pupils.
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.
