The literature concerning the symptomatology of the neuroses of the war is simply immense. According to Gaupp, for example, the following hysterical symptoms are to be observed. “Attacks of a slight nature up to those of the severest kind, with an _arc de cercle_ lasting for hours, sometimes with epileptic frequency, astasia-abasia, anomalies of the position and movement of the body even to going on all fours, all the varieties of tic and shaking tremors, paralyses and contractures in monoplegic, hemiplegic and paraplegic forms, deafness and deaf and dumbness, stuttering and stammering, aphonia and rhythmical screaming, blindness with or without blepharo-spasm, all kinds of disturbances of sensation, and most of all twilight states in quantities never before met with and in combination with phenomena of physical irritation and disorders”. You see, it is like a museum of glaring hysterical symptoms, and whoever has once seen it will plainly have to decline Oppenheim’s view, according to which purely neurotic symptoms are rarely seen in the traumatic neuroses of the war. Schuster draws attention to the frequent vasomotor and trophic phenomena; according to him, these are no longer psychogenic. Psycho-analysis, however, will agree with those who hold that these symptoms can originate to some extent from psychic causes, analogous to the physical alterations which can be produced under hypnosis. Finally, all the authors allude to the alterations in disposition, apathy and over-excitability, etc. after the trauma.
