This perhaps rather fantastic description is not a presentation of hysteria in the technical sense, but we may admit that it presents a state which, if not the real physiological counterpart of the hysterical convulsion, is yet distinctly analogous to the latter. The sexual orgasm has this correspondence with the hysterical fit, that they both serve to discharge the nervous centres and relieve emotional tension. It may even happen, especially in the less severe forms of hysteria, that the sexual orgasm takes place during the hysterical fit; this was found by Rosenthal, of Vienna, to be always the case in the semiconscious paroxysms of a young girl whose condition was easily cured;[286] no doubt such cases would be more frequently found if they were sought for. In severe forms of hysteria, however, it frequently happens, as so many observers have noted, that normal sexual excitement has ceased to give satisfaction, has become painful, perverted, paradoxical. Freud has enabled us to see how a shock to the sexual emotions, injuring the emotional life at its source, can scarcely fail sometimes to produce such a result. But the necessity for nervous explosion still persists.[287] It may, indeed, persist, even in an abnormally strong degree, in consequence of the inhibition of normal activities generally. The convulsive fit is the only form of relief open to the tension. "A lady whom I long attended," remarks Ashwell, "always rejoiced when the fit was over, since it relieved her system generally, and especially her brain, from painful irritation which had existed for several previous days." That the fit mostly fails to give real satisfaction, and that it fails to cure the disease, is due to the fact that it is a morbid form of relief. The same character of hysteria is seen, with more satisfactory results for the most part, in the influence of external nervous shock. It was the misunderstood influence of such shocks in removing hysteria which in former times led to the refusal to regard hysteria as a serious disease. During the Rebellion of 1745-46 in Scotland, Cullen remarks that there was little hysteria. The same was true of the French Revolution and of the Irish Rebellion, while Rush (in a study _On the Influence of the American Revolution on the Human Body_) observed that many hysterical women were "restored to perfect health by the events of the time." In such cases the emotional tension is given an opportunity of explosion in new and impersonal channels, and the chain of morbid personal emotions is broken.
