Tic

“ It is of course quite incorrect to say that each and every motor reaction to a pathological idea is a tic. The psychasthenic who in his fear of draughts shakes the door-knob a hundred times a day to make sure the door is shut, is not a martyr to tic ”

“ M. Cruchet, of Bordeaux, to whom frequent reference is made in this volume, has in several communications on tic expressed himself at some length, and some of these have made their appearance since the publication of Les tics et leur traitement. According to him, the original meaning of the word "tic" is a movement arising in a "bad habit," and there would never have been any confusion had the term "tic douloureux" not been introduced. ”

“ Pitres, [155] whose opinion is so weighty in matters neurological, considered a predisposition to tic as a sign of hysteria, for which neurosis the subjects of tic were candidates, and supported his contention by various clinical examples:
A resin-gatherer of Landes carried all day from tree to tree a notched stake of wood by which to climb up the pine-trunks. ”

“ Indolence, too—the mother of all the vices, according to the adage—favours the outbreak of tics, and accelerates their growth. The idle patient's thoughts are all for his tic; its perfecting taxes his inventiveness.
Mention may be made in passing of the effect of "professional movements" in predisposing to the subsequent apparition of a tic in the muscles concerned. ”

“ THE COMPLICATIONS OF TIC FOLLOWING in the train of the tics may come a number of complications, insignificant enough as a general rule, the dread of which may in some cases actually be instrumental in stimulating the will's activity to rid the patient of his tic. ”

“ A tic is a co-ordinated purposive act, provoked in the first instance by some external cause or by an idea; repetition leads to its becoming habitual, and finally to its involuntary reproduction without cause and for no purpose, at the same time as its form, intensity, and frequency are exaggerated; it thus assumes the characters of a convulsive movement, inopportune and excessive; its execution is often preceded by an irresistible impulse, its suppression associated with malaise. The effect of distraction or of volitional effort is to diminish its activity; in sleep it disappears. ”

“ In this general way we have indicated the distinctive features of tic, and we may take the opportunity to remind ourselves of their extreme variability.
In discussing the question of diagnosis, we shall have occasion to emphasise the importance of fruste, atypical, and transitional cases, not because we think they can be systematised as yet, but because they may be capable of new pathogenic interpretations which we cannot afford a priori to set aside. ”

“ The examination of the electrical reactions of the muscles concerned in a tic is a clinical method seldom, if ever, resorted to, and we can scarcely expect it to yield decisive results from the symptomatological aspect. As with the reflexes, it may happen that we cannot afford to neglect its diagnostic significance in certain cases. For example, we have had occasion to test its worth in studying the case of young J., whose trouble consisted in a clonic tic of elevation of the left shoulder, and a tonic attitude tic of the left arm whereby it was firmly applied against the body. ”

“ A tic of writing, however, is of a totally different nature. He who, without pen or pencil, is constrained by irrepressible impulse to go through the movements of writing with his fingers, convulsively, impetuously; and he who, without rhyme or reason, feverishly traces characters utterly at variance with the ideas he would express, are alike subjects of a writing tic. Of the former, we know no characteristic example, while in the latter case the study of the phenomenon would lead us too far into the realm of automatic writing and graphic impulsions. ”

“ CHAPTER III A STRANGE PROPOSITION Perhaps some of my readers may not know what the contrivance known as a "tic-tac" is like. Those of you who have made them, of course, do not need to be told. If you ever put them on any person's window, I hope you selected a house where there were only boys and girls or young people to be startled by the tic-tac. It is no joke, though at first it may seem like one, to scare an old person with the affair. So if any boy or girl makes a tic-tac after the description given here, I trust he or she will be careful on whom the prank is played. ”

“ In his article in the Dictionnaire Jaccoud, Letulle distinguishes two kinds of tics:
The convulsive tic consists of a series of partial convulsions, while the co-ordinated tic is the expression of some complex act by a sequence of muscular contractions for that purpose. In the former case the resulting movement is irregular, abnormal, and useless; it is a muscular "shock" evolved without reason and continued without effect.... The normal individual usually possesses in potentia all the elements for the genesis of a co-ordinated tic. ”

“ It is well to study the influence of the attention on these conditions; some tics are contingent on the direction of the patient's attention to them, others appear solely during times of distraction.... Education of movements by some form of drill may be of the greatest utility.
These general therapeutic indications are applicable to all kinds of tic, independently of their form and localisation. Moreover, they conform to the procedures advocated by Brissaud since 1893. ”

“ Even in these cases examination always reveals insufficiency of inhibition, to which are due the inception and the persistence of many "bad habits." We can thus appreciate the rôle of habit in the evolution of tics, and recognise the analogy they offer to all functional acts. A tic is frequently nought else than the ill-timed and inapposite execution of some function. We may even conceive a sort of functional tic centre, formed by nerve elements corresponding to the functional grouping of the muscles involved in the tic. ”

“ Among etiological factors of a general description, the rôle played by imitation is all-important, especially in the young. Mimicry is strong in the child's nature, and bad habits are quickly contracted. Should he be tainted with nervous weakness in addition, he is apt to tic on the slenderest pretext, in which case to encounter, or still more to be associated with, the subject of a tic would be the direst of misfortunes. ”

“ Tonic tic is of common occurrence in cases of mental torticollis. In that disease rotation of the head may be sustained for a considerable length of time without interruption, showing the permanent nature of the muscular contraction. Strictly speaking, we are concerned not with a sudden gesture, but with an attitude. Abundant evidence is forthcoming to substantiate its mental origin, and it may therefore be described as an attitude tic. ”

“ As it is inaccurate to describe as a tic a repeated gesture whose execution is normal in degree and in rapidity, so the mere immobility of a limb, or the prolonged contraction of a muscle, ought not to be called an attitude tic if the muscular effort does not differ from that which a healthy person would make to preserve the same position. In such circumstances we say that it is a stereotyped gesture or attitude. For the diagnosis of tic it is insufficient to establish the existence of a transient or permanent muscular contraction, and to note the inopportuneness of the movement ”

“ In its evolution the child's unmethodical reaction gives place to the rhythmical automatism of the adult. Perfection is the fruit of education.
But the person whose impetuous and uninterrupted blinking far exceeds the demand of the eye for lubrication is plainly troubled with excess, with "hypertrophy" of function. Herein may consist a tic, and, in fact, a large number of tics are nothing more than functional derangements of this kind. ”

“ An obsession ought to be called an obsession, and there ought to be a similar understanding in the case of phobias and fixed ideas, for each and all may exist independently of any motor reaction whatever, and therefore can never be classed with tic. It is only when the obsession or the fixed idea entails the automatic repetition of some motor phenomenon that a syndrome can be constituted to which the name of tic may be applied. As a matter of fact, a tic can no more be exclusively mental than exclusively muscular. ”

“ Disorders of the vasomotor system rarely fail to assert themselves in the subjects of tic, but they do not in any wise differ from such as are met with in the majority of "nervous" individuals. The average sufferer from tic is emotional, and apt to betray his emotion by blushing for the most childish reason. This symptom may be in itself trifling enough, yet it may afford the earliest indication of mental instability the nature and extent of which subsequent research will determine. ”

“ My tics upset my pince-nez, and I have to invent another tic to get it back into place. The absurdity of this vicious circle does not escape my observation, and I know I am its author, yet that cannot prevent my becoming its victim.
When the pince-nez is not in use I toy with the spring or with the cord, and a day seldom passes without my breaking the one or the other. As I wear spectacles at home one might suppose their relative stability would check my tricks; but their pressure on my temples and ears only serves to provoke fresh movements in a search for comfort. ”

“ Be that as it may, or even granting that in most patients the characteristic mental state or the neuropathic or psychopathic make-up exists in some measure to an abnormal extent, we do know that once the tic movements have made their appearance and begin to spread, so that the individual is thrown into the struggle to perform or not to perform the movement, the development of the psychic state which we find so patent in the more pronounced forms of tic, thereafter more or less rapidly occurs, no matter what the mental condition of the ticquer may have been previously. ”

“ Most subjects learn to still their tic during the physician's brief visit; further, most achieve a similar result while they remain inmates of a special institution; but as soon as they find themselves in their old quarters, so soon does the impulse to tic dominate them again. In fact, their victory is incomplete; the ground they gain is not held. ”

“ Here, then, is a tic springing from an ordinary visual impression. Any one can see the point of his nose if he wishes, but it does not come in his way should he be looking at something else; whereas our patient divides his attention between the end of his nose and the object of his regard, and his volatile will passes lightly from one to the other, incapable of concentrating itself on either. Force of repetition changes the voluntary act into an automatic habit, the initial motive for which is soon lost ”

“ Concentration of the attention may diminish the intensity or even inhibit the occurrence of a tic; inversely, a simple bad habit is manifested preferably during this very concentration. In the heat of physical or intellectual labour, we have all our favourite and characteristic tricks: we curl our moustache, we twist our beard, we scratch our forehead, we rub our chin, we nod our head, we fidget with our fingers in reading, speaking, reciting—in any mental or physical exercise requiring our attention we reveal innumerable little oddities of movement ”

“ Tissié had a young patient who did not tic at all while on holiday, but the reopening of his classes was the signal for a fresh outbreak. Similarly, no rule whatever seems to govern the duration of the times of relief; they may never be longer than a few seconds, or they may run into months. In the face of these data we cannot supply further generalisations; it will be sufficient if we impress on ourselves the importance of one fundamental element in the constitution of tic—viz. its repetition. ”

“ Numbers of people are in the habit of emphasising their words with those to-and-fro movements of the head that we call gestures of approval. Now, if the gesture be strictly appropriate to the thought present in the mind, it cannot be identified with the tics. On the other hand, its execution may be inopportune, in which case, provided the form remain normal, it is merely a stereotyped act, and must exhibit the additional features of abruptness and exaggeration ere it rank as a tic. ”

“ Results that steadfast and patient nurses and teachers are obtaining in an institution like Bicêtre may surely be obtained by the physician in his private practice, if the parents of a youthful candidate for tic would appreciate the importance of discipline and unite, intelligently and assiduously, in the task of education. How common it is to find them solicitous only of loading his tender brain with learning, instead of endeavouring, with all their mind and heart, to restrain deplorable bad habits that may one day blossom into tics, to the distress of all concerned! ”

“ As for actual paralysis supervening on a tic, the case recorded by Grasset [153] of a young girl in whom a tic of the right leg was succeeded by a trailing movement of the same limb in walking can hardly be considered conclusive, inasmuch as such incidents usually indicate hysteria or functional disturbances akin to tonic tics. ”

“ It is clear that determination of the tic's localisation and mode can come only with the mental evolution of the patient, and that the transformation from the psychical inconsistency of childhood to the stability of the adult is paralleled by the change in the tic's manifestations as the scale of age is ascended. ”
