Tics and Their Treatment

In spite of the fact that I know my recklessness to be absurd, that I see well enough the obstacles around and the danger of an encounter, I am conscious of a paradoxical impulse to do exactly what I should not do. In the same instant of time I want what I do not want. As I pass through a door I knock against the door-post without fail, for the sole reason that I would avoid it.

There is impatience in his speech. His volubility makes him out short his own phrases or break in upon the conversation of others. If an idea suggests itself, he must give it expression. Perhaps the word wedded to the idea is not at once forthcoming, yet he does not hesitate to invent a neologism, which is often amusing in spite of or because of its oddness, and if it please him he will enter it in his vocabulary and use it in preference to the other.

To wait is foreign to his nature. The least delay at table exasperates him; any order he gives must be executed instanter; no sooner has he set out than he would be at his journey's end. An obstruction or difficulty in the way is the signal for a fresh outburst; his irritation soon exceeds all bounds; his language degenerates into brutality, his gestures become increasingly violent and menacing.

It is not with any surprise, then, that we learn in O.'s case of incipient homicidal and suicidal ideas.

At times when my tics were in full force evil thoughts have often surged over me, and on two or three occasions I have picked up a revolver, but reason fortunately has come to the rescue.

As a matter of fact, the suicidal tendencies of some sufferers from tic are seldom full-blown. The will is too unstable to effect their realisation. Hence the patient's hints at doing away with himself are nothing more than empty verbiage. Similarly with the inclination to commit homicide, it vanishes as soon as it arises.

The term "vertigos" is used by O. to designate a long series of little "manias" or obsessional fears from which he suffers, among which may be enumerated dread of passing along certain streets and a consequent impulse to walk through others; dread of breaking any fragile object he holds in his hands, coupled with the temptation to let it fall; fear of heights, and at the same time a desire to throw himself into space.

I have often stood on the edge of the pavement waiting for a vehicle to pass, and at the moment of its approach darted across just under the horse's nose. On each occasion I have been conscious equally of the absurdity and yet of the irresistibility of the idea; each time the attempt to withstand it has been labour lost.

O. is a great nosophobe. At one time he was immoderately apprehensive of contracting hydrophobia, and used to flee from the first dog he saw. To his sincere regret he had several of his pet dogs killed, because of his conviction that they would become infected, although he felt such harsh measures to be quite unjustifiable. At a subsequent stage he turned syphilophobe for no adequate reason. He was alarmed lest a minute pimple on his chin should develop into a chancre. Recently his chief misgiving has been that he may become ataxic or demented.

Among his various afflictions mention must be made of an umbilical hernia, supposed to have originated in the chafing of his umbilicus by a belt he was wearing during a long spell in a canoe. As a matter of fact, the hernia is purely imaginary – at any rate, there is no trace of it to-day. Yet at the first it bulked very largely in his mind, and he is still fully persuaded of its reality, though no longer of its gravity.

O. further complains of all sorts of noises in his ears, but these are simply the ordinary sounds that one can produce in the middle ear by clenching the jaws together. He will not accept so obvious an explanation, however, preferring to regard them as indubitable evidence of the "lesion" with which he is preoccupied. The tinnitus, therefore, is rather of the nature of an illusion than of a hallucination.

He is distinctly emotional, and lives at the mercy of his emotions, but from their very bitterness he contrives to derive some pleasure. His passion for horse-racing is not due to the fascination of the sport, but to a bitter-sweet sensation which the excitement of the scene calls into being. He is indifferent to arrest or aggravation of his tics; all that he seeks is the association of a certain sense of anguish with certain "tremolos in the limbs," wherewith he is greatly delighted.

In the domain of his affections there does not appear to be any abnormality. O. is an excellent paterfamilias, adoring his children, but spoiling them badly at the same time. In this part of our examination we did not press for details, but as far as we have gathered he is capable of sympathies keenly felt though rarely sustained.

Thus, whatever be the circumstances, changeableness, versatility, want of balance, are manifested clearly in all his mental operations; and when he remarks himself on the youthfulness of his disposition, he is simply stating a truism as far as those who tic are concerned, for, in spite of the advance of years, their mental condition is one of infantilism.

Under our direction O. has devoted several months to the eradication of his tics, and he has not been slow to appreciate the aim of the method or to acquire its technique. One of the first results was the repudiation of various procedures more harmful than otherwise, and the successful endeavour to maintain absolute immobility for an increasing space of time. The outcome of it all has been a gradual diminution of the tics in number, frequency, and violence, and a corresponding physical and mental amelioration.

We do not intend in this place to enlarge on the details of our treatment: suffice it to say that it consisted in a combination of Brissaud's "movements of immobilisation" and "immobilisation of movements" with Pitres's respiratory exercises and the mirror drill advocated by one of us. To-day the utility of these measures is an accepted fact; but at the same time we rely on an inseparable adjunct in the shape of mental therapeusis, seeking to make the patient understand the rationale of the discipline imposed.

Our task has been lightened to an unusual degree through O.'s intimate acquaintance with the beginnings of his tics and his striking faculty of assimilation. On many occasions he has anticipated our intentions and of his own accord outlined a programme in harmony with the indications we were about to give him. Thanks to this happy combination of circumstances, the improvement effected by our treatment has been quickly manifested.

I am conscious of very material gain. I do not tic so often or with such force. I know how to keep still. Above all, I have learned the secret of inhibition. Absurd gestures that I once thought irrepressible have succumbed to the power of application; I have dispensed with my para-tic cane; the callosities on my chin and nose have vanished; and I can walk without carrying my head in the air. This advance has not been made without a struggle, without moments of discouragement; but I have emerged victorious, strong in my knowledge of the resources of my will… To tell the truth, at my age I can scarcely hope for an absolute cure. Were I only fifteen, such would be my ambition; but as I am, so shall I remain. I very much doubt whether I shall ever have the necessary perseverance to master all my tics, and I am too prone to imagine fresh ones; yet the thought no longer alarms me. Experience has shown the possibilities of control, and my tics have lost their terror. Thus have disappeared half my troubles.

The same sagacity that O. displayed in analysis of his tics has enabled him to grasp the principles of their subjugation. Notwithstanding that his guarded prognosis is evidence for his appreciation of the hindrance his peculiar mental constitution is to a complete cure, he has impartially put on record his definite progress towards health of body and mind.

Such, then, is the faithfully reported story of our model, such are his confessions.

During ten years' intercourse with sufferers from tic it has been our interest to analyse and reconstruct the pathogenic mechanism of their symptoms, and in the vast majority of cases it has been possible to determine the origin of the tics and to confirm the association with them of a peculiar mental state. We have thus been able to supplement earlier and weighty contributions to the subject by numerous suggestive instances, prominent among which is the case of O., whose spontaneous and impartial self-examination forms an invaluable clinical document. Its importance is enhanced by the fact that its observations are corroborated by a survey of other examples of the disease.

With commendable good-humour, keenness, and sincerity, O. has of his own accord plunged into the minutiæ of his malady, and exhibited a rare appreciation and precision in the scrutiny of his symptoms. The mere enumeration of them stamps the record as one of outstanding clinical importance, but it is the study of their pathogeny that is so fascinating. For a moment the doubt crossed our mind that O.'s explanations might be merely a reflex of information culled from scientific journals or of conversations with medical friends, but this is not so. He has been prevented by his profession both from cultivating a taste for and from devoting any leisure to psychological and physiological questions, while he evinces an actual antipathy to medical literature, fearful as he is of contracting disease. The point we are desirous of emphasising, therefore, is simply this: that the results of O.'s voluntary and unprejudiced self-examination are in perfect harmony with the declarations of our older patients and with the statements of the majority of those that have made a special study of the tics. For these reasons we have taken O. as the prototype of the tiqueur.

CHAPTER II

HISTORICAL

WE have just become acquainted with an individual who may, we believe, be considered the type of a species, and have described all his tics. What is a tic, then?

Its etymology has not much information to furnish. The probability is that the word was originally onomatopœic, and conveyed the idea of repetition, as in tick-tack. Zucken, ziehen, zugen, tucken, ticken, tick, in the dialects of German, tug, tick, in English, ticchio in Italian, tico in Spanish, are all derivatives of the same root. It matters little, in fact, since the term is in general use and acceptable for its shortness and convenience. In popular language every one knows what is meant by a tic: it is a meaningless movement of face or limbs, "an habitual and unpleasant gesture," as the Encyclopædias used to say. But the definition lacks precision.

A glance at the history of the word will reveal through what vicissitudes it has passed. We need but remind the reader of its exhaustive treatment in the Dictionaries, and refer him for an elaborate bibliography to a recent work by R. Cruchet,[1 - RENÉ CRUCHET, "Étude critique sur le tic convulsif et son traitement gymnastique," Thèse de Bordeaux, 1902.] to which we shall have occasion to return.

There is no justification for regarding the risus sardonicus of the ancients as a tic. All that we can say is that the phrase apparently stood for a complex of facial "nervous movements," whether accompanied by pains and paralyses or not. Nor can the rictus caninus or the tortura oris have been other than spasms or oontractures of the face.

Previous to its introduction as a technical term, the word tique, ticq, tic, was in current use in France, and applied in the first place to animals. In 1655 Jean Jourdin described the tique of horses. In eighteenth-century literature tic appears in the sense of a "recurring, distasteful act" – as expressed by the Encyclopædia– especially in individuals revealing certain eccentricities of mind or character. This old-time opinion is worth remembering, particularly in view of latter-day theories.

Once adopted by the eighteenth-century physicians, the application of the word was extended in various directions. André (1756) was the first to mention tic douloureux of the face, an affection excluded to-day by common consent from the category of true tics. Simple, painless convulsive tic, spreading from face to arms, and to the body as a whole, was differentiated by Pujol in 1785-7. During the earlier half of the nineteenth century no solid progress was achieved by the work of Graves, François (of Louvain), Romberg, Niemeyer, Valleix, or Axenfeld. It is to the clinical genius of Trousseau that we owe the rediscovery of tic, the careful observation of its objective manifestations, and the recognition of accompanying mental peculiarities.

In spite of the fact that he considered it a sort of incomplete chorea, and classed it[2 - TROUSSEAU, Clinique médicale de l'Hôtel Dieu, 1873, vol. ii. p. 267 et seq.] nosologically with saltatory and rotatory choreas and with occupation neuroses, Trousseau's original account remains a model of clinical accuracy:

Non-dolorous tic consists of abrupt momentary muscular contractions more or less limited as a general rule, involving preferably the face, but affecting also neck, trunk, and limbs. Their exhibition is a matter of everyday experience. In one case it may be a blinking of the eyelids, a spasmodic twitch of cheek, nose, or lip; in another, it is a toss of the head, a sudden, transient, yet ever-recurring contortion of the neck; in a third, it is a shrug of the shoulder, a convulsive movement of diaphragm or abdominal muscles, – in fine, the term embodies an infinite variety of bizarre actions that defy analysis.

These tics are not infrequently associated with a highly characteristic cry or ejaculation – a sort of laryngeal or diaphragmatic chorea – which may of itself constitute the condition; or there may be a more elaborate symptom in the form of a curious impulse to repeat the same word or the same exclamation. Sometimes the patient is driven to utter aloud what he would fain conceal.

The advantage of this description is its applicability to every type of tic, trifling or serious, local or general, from the simplest ocular tic to the disease of Gilles de la Tourette. Polymorphism is one of the tic's distinguishing features.

Apart from his studies in objective localisation, Trousseau, as we have seen, recognised that the tic subject was mentally abnormal, but the credit of demonstrating the pathogenic significance of the psychical factor is Charcot's. Tic, he declared,[3 - CHARCOT, Leçons du mardi, 1887-8, p. 124.] was physical only in appearance; under another aspect it was a mental disease, a sort of hereditary aberration.

Advance along the lines thus laid down has been the work more especially of Magnan and his pupils, of Gilles de la Tourette, Letulle, and Guinon. A meritorious contribution to the elucidation of the question is the thesis of Julien Noir, written under the inspiration of Bourneville and published in 1893. The still more recent labours of Brissaud, Pitres, and Grasset in France, and of others elsewhere, have added materially to our knowledge.

Confining ourselves for the present to the discussion of the latest interpretations put on the word tic, we may be allowed the remark that if the influence of Magnan's teaching has been instrumental in making our idea of tic conform more to the results of observation, nevertheless his view is not without its dangers.

In the opinion of Magnan and his pupils, Saury and Legrain[4 - LEGRAIN, "Du délire des dégénérés," Thèse de Paris, 1885-6.] in particular, the tics do not form a morbid entity; they are nought else than episodic syndromes of what Morel called "hereditary insanity," that is to say, of what is usually designated nowadays "mental degeneration."

Now, if by degeneration be meant a more or less pronounced hereditary psychopathic or neuropathic tendency which betrays itself by actual physical or psychical stigmata, then tic patients are unquestionably degenerates. If degeneration unveils itself in multifarious psychical or physical anomalies, the subjects of the tic are undoubtedly degenerates. If a degenerate may suffer from one or other variety of aboulia, or phobia, or obsession, the man with tic is a degenerate too.

Thus understood, the epithet may be applied to all individuals affected with tic. In fact, they must be degenerates, if the word is to be employed in its most comprehensive sense. But the explanation is insufficient, inasmuch as the converse does not hold good; all degenerates do not tic.

We may be safe in maintaining, then, that tic is only one of the manifold expressions of mental degeneration, but we are not much enlightened thereby. Obsessions and manias similarly are indications of mental deterioration, yet the fact conveys very scanty information as to their real nature. Physical anomalies – ectrodactyly, for instance – betoken physical degeneration, no doubt; but are inquiries to cease with this categorical assertion? Such certainly was not the idea of those observers whose is the praise for having demonstrated the common parentage of the heterogeneous manifestations of degeneration. Synthesis cannot exclude the work of analysis, and in practice there is scarcely a case to which this doctrine is not pertinent.

Every physical and every mental anomaly is the fruit of degeneration; every individual who is a departure from the normal is a degenerate, superior or inferior as the case may be. As instances of the latter we may specify the dwarf and the weak-willed; of the former, the giant and the exuberant. This sane and comprehensive conception of the subject must command universal acceptance as a synthetic dogma, but it cannot supplant the description and interpretation of individual facts. However legitimate be our representation of tic as a sign of degeneration, it is obviously inadequate if we rest content with styling its subject a degenerate.

Unfortunately the inclination too often is to be satisfied with the term, and to imagine that therewith discussion terminates. Still more unfortunately, in concentrating their attention on the mental aspect of the disease, some have altogether lost sight of one of its fundamental elements, viz. the motor reaction, and have conceived the possibility of its occurrence without any tic at all. Cruchet actually postulates the existence of an exclusively psychical tic, with no external manifestation.

To these questions, however, we shall return. The present introductory sketch is intended merely to demonstrate the ease with which ambiguity arises, and the desirability of its removal. We are fully conscious of the value of the work of Magnan and his school in emphasising a phase of the subject the exposition of which can only result in gain.

The investigation of the motor phenomena of tic is no less encircled with perplexities. Not only are the troubles of motility boundless in their diversity and correspondingly difficult to classify, but they also bear so close a resemblance to a whole series of muscular affections that one is tempted to describe a special symptomatology for each individual case.

For several years there has been, more especially outside of France, a manifest tendency to aggregate all convulsions of ill-determined type into one great class, under the name "myoclonus"; and into this chaotic farrago, it is to be feared, will tumble a crowd of conditions which should be studiously differentiated: the tics, electric and fibrillary choreas, paramyoclonus multiplex, etc., etc.

In the present state of our knowledge, according to Raymond,[5 - RAYMOND, Clinique des maladies du système nerveux, vol. i. 1896, p. 551.] we must be guided by the lessons of clinical experience, which teach us, first, that the varying modalities of myoclonus develop from the parent stock of hereditary or acquired degeneration; and, secondly, that transitional forms which do not fall into any of the received categories are of common occurrence.

From a general point of view, the deductions are entirely reasonable. There is a suggestive analogy between these conditions and the muscular dystrophies in the persistence with which their multiplicity seems to defy the efforts of classification. The analytic stage witnessed the rapid evolution of such clinical types as the facial, the facio-scapulo-humeral, the juvenile, the pseudo-hypertrophic, not to mention others that bear the name of their observer; but it has been succeeded by the synthetic stage, whose function it is to incorporate all the former myopathies in the comprehensive group of "muscular dystrophy."

Yet here, again, peril lurks in too hasty a generalisation. To give the disease a name is not equivalent to pronouncing a diagnosis. The denominations "myoclonus," "muscular dystrophy," "degenerate," are alike inconvenient. Their scope is at once too inclusive and too exclusive. They may be indispensable; they are assuredly not sufficient.

The possibilities of misapprehension do not end here.
