Case 294. (Zanger, July, 1915.)
Project Gutenberg EPUB3 edition
Southard, Elmer Ernest
Several years before the war, a cavalry officer had a severe concussion of the brain after a fall from his horse, but got no manifest symptoms therefrom except a mild transient deafness. There must have been a vestibular nerve injury, however, since there was a marked bilateral subexcitability of this apparatus later determined.
In September, 1914, as the result of strains and privation in the field, he got vertigo and lachrymose spells, with some obsessions as though he would have to shoot himself in the foot or spring out at the enemy from the trench.
In hospital at Jena, insomnia, anxiety, excessive perspiration and salivation, feelings of the death of various parts of the body, especially the forearms and hands, associated with hypesthesia of the parts, were determined. He had a feeling of vertigo on walking and was very sensitive to noise. He now developed a very intense and very variable degree of deafness on both sides, diagnosticated as nervous deafness. The caloric test demonstrated vestibular subexcitability above mentioned. We may suppose that in this already injured organism fresh disorder had set in on a psychogenic basis in the same region that had been injured years before.
