Hysteria was known to the ancients and in fact is as old as the written history of mankind. Considered essentially a disease of women, it was given its present name which is derived from "hysteron," the Greek name for the womb. We know to-day that men also are victims of this malady, though it arises under somewhat different circumstances than is the case with the other sex. Men and women, living in the same world and side by side, are placed in greatly different positions in that world, are governed by different traditions and are placed under the influences of differing ambitions, expectations, hopes and fears. Hysteria arises largely out of the emotional and volitional reactions of life, and these reactions differ in the sexes. It was a group of French neurologists, headed by Charcot--and including very illustrious men, such as Janet and Marie, who paid the first scientific attention to the disease. Under their analyses hysteria was defined as a mental disease in which certain symptoms appeared prominently. 1. Charcot especially paid attention to what are known as the attacks. The hysteric patient (usually a woman, and so we shall speak of the patient as "she") under emotional stress and strain, following a quarrel or a disagreement or perhaps some disagreeable, humiliating situation, shows alarming symptoms. Perhaps she falls (never in a way to injure herself) to the floor and apparently loses consciousness, closes her eyes, rolls her head from side to side, moans, clenches her fists, lifts her body from the floor so that it rests on head and heels (opisthotonic hysteria), shrieks now and then and altogether presents a terrifying spectacle. Or else she twitches all over, weeps, moans, laughs and shouts, and rushes around the room, beating her head on the walls; or she may lie or stand in a very dramatic pose, perhaps indicating passion or fear or anger. The attacks are characterized by a few main peculiarities, which are that the patient usually has had an emotional upset or is in some disagreeable situation, that she does not hurt herself by her falls, that consciousness is never completely abolished and fluctuates so that now she seems almost "awake" and then she seems almost in a complete stupor, and that the expression of emotion in the attack is often very prominent. These symptoms are readily differentiated from what is seen in epilepsy.[1] [1] The French writers of the school of Babinski deny that the above symptom and even the majority of the following have a real existence in hysteria. The English, American and German neurologists and the rest of the French school describe hysteria substantially as I am here describing it.
