Despite the notion of hysterical soldiers clashing with nationalist and revanchist ideas of the time, diagnoses of hysteria were soon made by military medical personnel.
Nonne was originally skeptical, but ultimately became a proponent of the male hysteria diagnosis when dealing with the neurotics produced by the First World War.
[5]: 437 By this point, the incidence of "classical" hysteria in males was accepted by Freud's audience, but Charcot's traumatic variant was still controversial and evoked discussion among the present medical doctors.
[7]: 320–2 Charcot's earlier work, meanwhile, was ignored, and shell-shock sufferers were regarded by their physicians as displaying the symptoms of "womanish, homosexual or childish impulses".
Symptoms that were previously considered somatic were reconsidered in a new light; trembling, paralysis, nightmares, mutism and apathy were grouped together in a broad spectrum psychological disorder known as "war neurosis".
Eric Leed writes that war neurosis was a result of the breakdown of the previously personal relationship of the soldier and his means of fighting.
Rivers considered the idea that the traumatized men resorted to neurotic behavior because of a loss of their usual defense mechanism – physical hand-to-hand combat.
[11] Showalter argues that mental breakdowns of soldiers during the war was a form of protest against pre-conceived notions of Edwardian manliness that demand unifying patriotism and stoic lack of emotion.
He was of the belief that the physical signs and symptoms of hysteria were identical in both sexes but claimed that the condition presented itself differently in the minds of men and women.
Rivers' treatment drew heavily from Freud's 'talking cure', because he focused primarily on discussing hidden memories of trauma and dissecting war nightmares.
Unlike other shell shock hospitals of the time, Craiglockheart allowed officers to engage in therapeutic hobbies such as writing, sports and photography.
The hospital magazine, Hydra was a wonderful insight into the minds of lower-ranked officers, physicians and nurses alike – "Within its pages are a series of fascinating and revealing cartoons depicting, among other things, the traumatic nightmares most of those at the hydro suffered, Rivers' mystical reputation, and the often mixed feelings of soldiers on leaving the place".
The most famous anti-war poem, Dulce et decorum est, was written at the hospital in 1917 by a renowned poet and war neurosis sufferer, Wilfred Owen.
[16] Regeneration (1991) is the first of a series of novels that deals with the psychological trauma caused by World War I on English officers who fought on the front lines.
The plot revolves around the character of Siegfried Sassoon, a decorated officer who is sent to Craiglockhart War Hospital in Edinburgh because he is said to be suffering from "Shell Shock".
The book shows the struggle of its characters as they grapple with guilt, hopeless and fear as they try to rationalize life on the front lines and back home.
