Excerpt from The Iowa State Medical Reporter, Vol. 2: A Monthly Journal of Medicine and Surgery; July, 1884
In simple concussion, he says, we have a history of some violent jar or jolt, which, although productive of no appreciable le sion, doubtless alters the functional integ rity of the cord much as a blow may affect a magnet. The initial giddiness and con fusion are followed by a state of unusual calm and self-possession which, in its turn, when the sustaining excitement of the hour has passed, is followed by an emotional revulsion. The next day the patient feels stiff and bruised, and, in a few days or weeks, finding himself une qual to his accustomed tasks, he is forced to seek medical aid. Weeks, and even months, may lapse before the more posi tive and serious symptoms set in, but at no time - and this is a point to which es pecial attention is called - is there a re turn to the full normal standard of pre vious health either physical qr mental. The patient looks ill and worn, and is very easily fatigued, while his symptoms grow more and more confirmed as time wears on. His countenance is usually pal lid, his memory defective, thoughts con fused, will enfeebled and vacillating, tem per fretful, and sleep disturbed. His head is giddy, throbbing or heavy. There are often loud and incessant noises - roaring rushing, singing, etc. - in his ears. As: thenoapia, photophobia, muscae volitan tes, and various subjective spectra, har ass him. His sharpness of sight and hearing, one or both, may be affected either lessened or increased. Taste and and smell, too, may be perverted or lost, though they are not likely to be disturbed. There is rarely an impairment of speech.
