Convulsions or general spasms are among the most prominent of hysterical manifestations. Under such names as hysterical fits, paroxysms, attacks, seizures, etc. they are described by all authors. Their presence has sometimes been regarded as necessary in order that the diagnosis of hysteria might be made; but this, as I have already indicated, is an erroneous view.
Under hysterical attacks various conditions besides general convulsions are discussed by writers on hysteria; for instance, syncope, epileptiform convulsions, catalepsy, ecstasy, somnambulism, coma, lethargy, and delirium. According to the plan adopted in the present volume, catalepsy, ecstasy, somnambulism, etc. will be considered in other articles, and therefore my remarks at this point will be limited to hysterical general convulsions.
These convulsions differ widely as to severity, duration, frequency, motor excitement, and states of volition and consciousness. Efforts have been made to classify them. Carter70 describes three forms as primary, secondary, and tertiary. In the primary form the attack is involuntary and the product of violent emotion; in the secondary it is reproduced by the association of ideas; and in the tertiary it is deliberately shammed by the patient. Lloyd71 divides them into voluntary and involuntary forms, and discusses the subject as follows: “The voluntary or purposive convulsions are such as emanate from the conscious mind itself. Here are the simulated or foolish fits into which women sometimes throw themselves for the purpose of exciting sympathy or making a scene. I am convinced that a large number of hysteric fits are of this class: these are the patients who are cured by the mention of a hot iron to the back or the exhibition of an emetic. The involuntary forms of convulsion are more important. They happen in more sensible persons, and some of them are probably akin to starts, gestures, and other forcible or violent expressions of passions or states of the mind. A person wrings the hands, beats the breast, stamps upon the floor in an agony of grief and apprehension, and if terror is added he trembles violently. It is no great stretch of the imagination to suppose that great fear, anger, or some kindred passion, acting upon the sensitive nervous organization of a delicate woman or child, should throw them into a convulsion. This, in fact, we know happens. Darwin72 believes that in certain excited states of the brain so much nerve-force is liberated that muscular action is almost inevitable. He instances the lashing of a cat's tail as she watches her prey and the vibrations of the serpent's tail when excited; also the case of an Australian native, who, being terrified, threw his arms wildly over his head for no apparent purpose. The excito-motor reflexes of the cord may possibly take on true convulsive activity if released from the control of the will, which, as already said, is apt to be weak or in abeyance to this disease. Increased temperature is stated by Rosenthal to be always present in the great fits of epilepsy and tetanus, but absent in those of hysteria.”

This subdivision of hysterical convulsions into voluntary and involuntary, or purposive and non-purposive, is a good practical arrangement; but the four groups into which I have divided all hysterical symptoms—namely, the purely involuntary, the induced involuntary, the impelled, and the purely voluntary—include or cover these two classes, and allow of explanation of special cases of convulsion which cannot be regarded as either purely shammed or as entirely, and from the first, independent of the will.
Absolutely involuntary attacks with unconsciousness constitute what are commonly called hystero-epileptic seizures, and will be described under Hystero-epilepsy.
The voluntary, impelled, or induced hysterical fit may be ushered in in various ways—sometimes with and sometimes without warning, sometimes with wild laughter or with weeping and sobbing. The patient's body or some part of it is then usually thrown into violent commotion or convulsion; the head, trunk, and limbs are tossed in various directions. Frequently the arms are not in unison with each other or with the legs. Screaming, shouting, sobbing, and laughing may occur during the course of the convulsive movement; sometimes, however, the patient utters not a word, but has a gasping, noisy breathing. She may talk in a mumbling, incoherent manner even during the height of the attack. She is tragic in attitude or it may be pathetic. The face is contorted on the one hand, or it may be strangely placid on the other. Quivering, spasmodic movements of the eyelids are often seen; but the eyes are not fixed and turned upward with dilated pupils, as in epilepsy. The patient does not usually hurt herself in these purposive attacks. She may or may not appear to be unconscious. She does not bite her tongue, nor does she foam, as does the true epileptic, although she may spit and sputter in a way which looks somewhat like the foaming of epilepsy. She comes out of the fit often with evident signs of exhaustion and a tendency to sleep, but does not sink into the deep stupor of the post-paroxysmal epileptic state. The paroxysm may last a few or many minutes. Large quantities of colorless urine are usually passed when it is concluded.
Hysterical paralysis, so far as extent and distribution are concerned, may be of various forms, as (1) hysterical paralysis of the four extremities; (2) hysterical hemiplegia; (3) hysterical monoplegia; (4) hysterical alternating paralysis; (5) hysterical paraplegia; (6) hysterical paralysis of special organs or parts, as of the vocal cords, the œsophagus and pharynx, the diaphragm, the bowels, and the bladder. Russell Reynolds73 has described certain cases closely allied to, if not identical with, some forms of hysterical paralysis under the head of paralysis dependent upon idea. These patients have a fixed belief that they are paralyzed. The only point of separation of such cases from hysterical paralysis is the absence of other hysterical manifestations. Perhaps it would be better to regard the condition either simply as hysterical paralysis or as a true psychosis—an aboulomania or paralysis of the will. Such cases often last for many years.
