Tics and Their Treatment

The antagonistic gesture is, in some instances, contemporaneous with the wryneck, although more usually it is not in evidence until months or years after the distortion has become inveterate.

Mental torticollis is characterised by remarkable chronicity. We have seen cases of ten or fifteen years' duration and more. Temporary remissions have been known, however, and alternations with other tics or with psychical affections. At the Congress of Limoges, the following case was reported by Briand:

As the result of a bicycle accident, a young man developed a torticollis which ordinary treatment was sufficient to cure, and it remained in abeyance until he entered a government school, when its place was taken by a tic of the shoulder, with twitching of the mouth and eye. At the approach of the annual vacation the tic disappeared, and the torticollis, for some simple reason or other, became obvious again. The latter had once more been got under control by the time the holidays were over, but on the patient's re-entering school the shoulder tic again manifested itself, and this sequence recurred several times. A permanent cure was eventually effected, but he continued as psychasthenic as ever.

In another of Briand's cases torticollis alternated with astasia-abasia, a sort of "mental paraplegia." The patient could not walk at all without crutches, or without a little minerve, which he used either to steady his gait or to keep his head straight.

No doubt facts such as these just given are rather uncommon, but there is abundant reason for considering mental torticollis one of the most tenacious and intractable of all tics.

TICS OF THE TRUNK

The rarity of isolated involvement of the thoracic muscles, and the frequency of their inclusion in tics of the neck and limbs, arise from the fact of their insertion into the bones of the extremities, and consequently conditions affecting them will be dealt with in another place. Omitting for the present all reference to the muscles of respiration, we have to consider only the vertebral and abdominal groups. These pass into activity in the rhythmical salutation and balancing movements so common among idiots, movements bearing the most intimate analogies to the tics, though their peculiarity of rhythm justifies their separate classification.

Tonic contractions that find expression in attitude tics of the body are generally associated with tonic tics of the neck and limbs, and in some cases of mental torticollis the deformation they produce is extensive.

The material part played by the abdominal muscles in the function of respiration explains their implication in respiratory tics. A curious case of this kind has been published by Pierre Janet98:

A woman thirty-two years old had been afflicted for three years with a respiratory tic that consisted in imitating with the lips the neighing of a horse, and with a still more extraordinary tic of the abdominal parietes. She appeared to "swallow her stomach"; in other words, her abdomen, prominent enough in its ordinary state, was flattened and retracted, and the skin so stretched and dragged upwards that the umbilicus approached the costal margin. Just as it seemed to be disappearing, to be "swallowed," relaxation of the abdomen slowly took place, and this procedure was repeated ten or twelve times a minute. Pressure on the epigastrium inhibited the abdominal movement, but was accompanied by immediate renewal of the neighing, whereas with the relief of the pressure the sequence of events was inverted.

TICS OF THE ARM AND OF THE SHOULDER

In the upper extremity tics may affect the various muscles of the shoulder, arm, or forearm. Shoulder tics are of frequent occurrence, and often owe their origin to the discomfort of a tight sleeve or of a badly fitting collar. They are generally a concomitant of neck tics, in particular of mental torticollis.

In this connection we may recall the case of O., and supplement it by a description of another – viz. young J.

This boy J. had always been "nervous," and affected with "nervous movements" of face or limbs. At the age of thirteen years, when playing in the house one day, he knocked himself against an open door and bruised the shoulder near the outer end of the left clavicle. Three or four days later all pain and discolouration had vanished, and the child's movements were perfectly unimpeded again. His tics continued as before.

Two months after this little accident was over and forgotten, it was remarked that at the seat of the contusion there was a slight swelling, quite painless and scarcely even uncomfortable, but disquieting enough to the parents and thought to require applications of neapolitan ointment and the actual cautery. This line of treatment effected no alteration in the local condition, but it had other far-reaching consequences, for the boy noticed the anxious interest aroused by the singular exostosis, and began to devote attention to it himself. From the moment that his parents manifested their apprehension by words of pity and by solicitous examination, his tics developed a preference for the left shoulder, though continuing to exhibit themselves in the face and the right arm. He would unexpectedly elevate or depress his shoulder, would shrug it forwards or brace it back, accompanying the performance with inclination of the head or abduction of the upper extremity. He was very positive as to the painless nature of his affection; his sole complaint was of a certain stiffness in the joint, and at the thought of it came an impulse to move the shoulder which there was no resisting. The twitching would disappear for a time for no fathomable reason, and reappear again. By the exercise of a little circumspection he could temporarily overcome it, and during sleep it subsided entirely.

The facts – duly controlled and confirmed by the parents – that involuntary shoulder movements preceded not merely the application of the counter-irritants, but the accident itself, and that the unique difference lay in the similarity of his shoulder tic to all his other tics before the trauma, and in its marked preponderance in degree and frequency after, especially subsequent to the treatment, are of weighty diagnostic significance. Plainly the injury and its sequelæ did not exert any causative influence on the tic, and while it is conceivable that the clavicle may have been cracked and an exostosis ensued, we must repeat that the pre-existence of the movements in question negatives the possibility of their being attributable to nerve irritation from a periosteal overgrowth. The only effect which the accident and its consequences had was to intensify the patient's preoccupation and to determine the incidence of the tic.

By the month of October, 1900, the latter was at its height, and had reached a state where differentiation of the movements and of their muscular counterparts was attended with no little difficulty. They could be resolved into four principal groups, whereby the shoulder was raised, lowered, advanced, or drawn back, respectively. The first of these presented no unusual feature except that with it the head was commonly inclined to the same side; but the act of depression was rather peculiar, inasmuch as it was achieved by a sudden contraction of the inferior muscles of the scapula, together with the pectoralis, which drew the humeral head downwards, elongated the capsule, and stretched the deltoid fasciculi over it. The space thus left between the separated articular surfaces was partly filled in by the neighbouring ligamentous and muscular structures. Anterior or posterior projection of the shoulder took place at the expense of an actual subluxation, the head of the humerus bulging under the pectoral or the scapular muscles. Each and every movement was accompanied by articular cracking, sometimes so insignificant as scarcely to be pathological, to which, nevertheless, the boy attached extravagant importance and devoted methodical investigation.

Ordinary arm movements were, without exception, unimpaired, nor was any bony malformation discoverable. The two shoulders were practically symmetrical, though the upper border of the trapezius on the left side was, if anything, thickened and more prominent than its fellow, and the same applied to the left scapular muscles. Horizontal extension of the left arm revealed a slight tremulousness, quite distinguishable from pathological tremor and from fibrillary twitching, and wholly comparable to what is seen when, by reason of a fracture or otherwise, a limb is for a certain length of time prevented from executing movements of extension.

[Beating or striking tics (the patient using his own fist against himself) arise from the attempt to alleviate some insignificant pain or irritation; but tics of this kind are in their turn the exciting cause of local discomfort, and so of fresh tics. In spite of the obviousness of this, it is often difficult to convince the patient that his movements are prior, not consecutive, to the unpleasant sensations.99]

Finally, tonic tics of the upper extremity find expression in attitudes that vary with the localisation of the contraction. We have already had occasion to observe this, which is an almost constant phenomenon in mental torticollis, in the case of young J., in Madame T., and in N., where, it will be remembered, the all but permanent elevation of the right shoulder seemed traceable to the habit of cutting stuffs with a pair of large scissors.

TICS OF THE HANDS – SCRATCHING TICS

Scratching movements are infinite in their variety, and since the co-operating muscles vary in each case, the question of muscular localisation is of secondary interest.

The object in view in the act of scratching is relief from some such source of cutaneous irritation as a pimple, an abrasion, a burn, the bite of an insect, etc., and so long as the cause persists, the function is being rationally exercised; but to persevere mechanically, involuntarily, immoderately, in the absence of pruritus or of other paræsthesiæ, is a sign that the functional act is growing into a tic. Innumerable tics are thus developed, and they are intimately associated with biting tics.

S. passes his hand every instant over his forehead, O. over his eyes, T. over her lips, P. over his moustache, young J. over his budding whiskers, etc., etc. These elementary tics are scarcely more than stereotyped acts, and may maintain the semblance indefinitely, though there is also the likelihood of their becoming immeasurably more pronounced.

M. scratches his lips with his nails till they are bleeding; E. suffers from a facial tic, and scrapes at his forehead and temples to such an extent that his complexion is perpetually blooming with a crop of little bleeding excoriations; in some places, as a result of ceaseless rubbing and tapping, the skin is thickened and discoloured – a condition that might be known as "scratchers' corns." Madame W. used to tear at her toe nails with her fingers whenever she had retired for the night; and at the present time, as a result of incessantly passing a fine gold chain between the pulp of her fingers and the nails, she has succeeded in half detaching the latter from their bed.

A case reported by Raymond and Janet100 is one of unusual severity.

A little girl ten years old was covered from head to foot with scabs and sores, some of which on the body were several centimetres in diameter and looked very ugly. These she had contrived to inflict on herself, in spite of every precaution and admonition. It appeared that successive attacks of measles and of whooping-cough at the age of five had entailed long rest in bed, and had been followed by a tardy convalescence, in the course of which the development of a few pimples on the forehead was the signal for her to commence scratching them and any other part of her body where there was the least discomfort, or where the skin was at all roughened. This merciless self-mutilation ended in the production of large and painful excoriated areas; nevertheless a tic had sprung from the habit, and it remained inveterate.

Another analogous case is quoted by the same observers101:

In this instance, apart from the obvious existence of a confirmed tic, the patient had a curious look about the eyes which a nearer glance showed was caused by complete absence of the eyelashes. He had a trick when speaking or talking of lifting his right hand and running his finger carefully along the margin of the lids, and if it encountered an eyelash projecting beyond the skin, he promptly plucked it out. The endless repetition of this toilette rendered the eyelids barren of lashes.

TICS AND WRITING

Are writing tics to be recognised?

Tricks and turns of writing, however ridiculous, involuntary, and ingrained they be, scarcely deserve to be called tics. Those flourishes and ornaments that some people take delight in adding to their letters can no more be considered the expression of a pathological state than the superabundant gestures, the redundant words, the exuberant mimicry, of which others are so prodigal. They are simply modes of exteriorisation peculiar to the individual, and if in their superfluity and excess they go beyond the strict requirements of the case, still, they are only mannerisms of writing or of speech. Their manifestation is rigorously dependent on the performance of some function, and is not preceded by an imperious need of execution.

More akin to the tics is stereotypy of written language, so common an appanage of mental disease. The term is intended to include such habits as repetition of a particular formula, underlining of words, constant use of hyphens in the same way, writing of certain pages in a hand differing from the rest of the manuscript. Séglas102 has done excellent work in the analysis and interpretation of these troubles. One of his patients used every week to write letters bearing the same complicated address, and signed invariably with the following rigmarole:

De Senez de Mesange, great Prince Napoleon, great Prince of the Blood Royal and Imperial of the Universe, great Admiral, great Marshal of my armies, … great Procurator of the Republic, Royal and Imperial, great President of the Republic, Royal and Imperial, great Pope, great Duke, great King, great Emperor – Jupiter, Louis XIV. and Louis XV.

Another would write after almost every sentence:

Dieu et son droit, let him be cursed in all that is most cursed qui mal y pense.

This was a sort of exorcism, a cabalistic formula enabling the persecuted unfortunate to defend herself against the wiles of the evil spirit.

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. We must content ourselves with recalling its occurrence in an undeveloped form in the case of O.

Among those who are affected with tics, disorders of writing are very infrequent, even where the tic's exhibition is displayed in the upper extremities. One of the distinctive features of tics, in fact, is the brevity of the interruption they cause in the performance of any voluntary act on the part of the patient. Tics of arm or hand effect but little modification of his writing. He is rarely taken aback by his tic's convulsive demonstration. He can permit the co-existence, on a perfect understanding, of two automatic acts, normal and abnormal, writing and tic.

One of Guinon's patients was wont to proceed in the following way: if asked to write, he would lean on the table, pick up his pen, and just ai it was about to touch the paper, make several little movements of circumduction with his right hand, as a child does. Thereafter, he would sometimes pass on at once to trace the letters; at other times he would have to grind his teeth, contort the right half of his face, put out his tongue, pucker his nose, or dip his pen spasmodically into the ink ten consecutive times – ejaculating ahem! ahem! the while – before being able to commence. He would often cease altogether, to make one or two grimaces, or to wave his hand about. As far as the actual writing was concerned, its distinctness and evenness were no less praiseworthy than its style and content, and though a glance at his gesticulations led one to expect blots and irregularities in his manuscript, he conducted his task with assurance and correctness.

Of course, if the tic, whatever it be, exceed a certain limit of frequency and violence, accurate writing may amount almost to a physical impossibility, in which case the patient usually discontinues, although if called on to exercise his will he can always pen a few words and even a few lines. However this may be, the spots and scrawls and zigzags and shaky cramped characters we associate with such organic affections as tabes, Friedreich's disease, paralysis agitans, etc., are wholly exceptional in the case of tic.

While, then, disturbances of the function of writing are seldom ascertainable in those who tic, we have convinced ourselves on more than one occasion of the truth of the converse, that the exercise of the faculty is sometimes intimately combined with the evolution of tics of neck and shoulder.

S. dated his mental torticollis from the time when he used to copy figures for several hours a day. As a matter of fact, he wrote an excellent hand, and experienced no difficulty in performing the necessary movements, but continued writing increased the rotation. N.'s torticollis was the sequel to long spells of office work, during which he never laid down his pen. In the case of L., the wryneck and the convulsions of the right arm were preceded by a sort of writers' cramp of the right hand, and subsequently of the left.

In the accompanying instance, the development of which one of us has had the opportunity of observing, the appearance of the torticollis was at first confined to occasions of writing, but gradually it came into evidence with other arm actions, and eventually established itself in a permanent fashion.

P., fifty years old, occupies a responsible position in a big railway company, is director in a large office, and performs his duties with peculiar conscientiousness and zeal. Naturally an emotional man, he was much distressed by an unusually sad family bereavement about the middle of 1900, which coincided with a period of great overwork. As he was obliged every day to arrange innumerable papers and affix his signature to them, he began to notice that each time he wrote his name his head turned to the right involuntarily, and he felt a sensation of discomfort in the neck and right shoulder. He tried to remedy the faulty position by holding his chin with his left hand; nevertheless, in the course of the next few months the movement began to assert itself not merely as he wrote his signature, but also when he cut his food at table, or sharpened a pencil, or trimmed his finger nails.

October 14, 1901.– Whenever P. proceeds to write, his head is immediately rotated to the right and maintained in that attitude by successive contractions. Simultaneously, the right side of the face is distorted by a grimace, the right eye blinks, and the right corner of the mouth is drawn down by a strong effort of the platysma. The state of affairs is unaltered so long as he is handling a pen, though, curiously enough, his caligraphy itself is flawless. The more firmly he grasps his pen, the more violent the spasms; the substitution of a pencil abates them somewhat, as does writing on the floor with a cane, while if he traces letters in the air in front of him with his finger, they do not occur at all. When both hands are occupied in writing, the head still turns to the right.

He was advised to incline his head on his right shoulder as he wrote, and to force his right sternomastoid to contract, in carrying out which instructions he managed to form several hooks and rods correctly without any torticollic movement, and was both elated at the success of the experiment and dejected by the thought of his infirmity. Accordingly all writing was prohibited, all signature making reduced to a minimum, and he was recommended a simple pencil exercise, to be performed with slowness and deliberation while the head was kept in the position just mentioned. Identical rules were to be observed when eating, etc, and a tepid bath was prescribed night and morning.

October 21.– Some improvement has taken place. The patient is less uneasy and less discouraged. Dissociation of the movements of writing into their component parts and isolated execution of each are accomplished admirably at the first trial, less well the second, and at the third, rotation recommences. Fatigue rapidly increases, and P. sinks again into impatience, enervation, and despair. Occasionally his anguish is so extreme he is covered with perspiration even after the most elementary pencil drill, and is forced to mop his brows.

November 21.– Improvement is maintained. He can now write various letters and short words at his ease, though he still feels uncomfortable in anything requiring a more sustained effort. Otherwise, he is conscious of greater control over his head.

December 15.– The amelioration has not persisted. While he was paying a visit to the barber's, and having his hair cut, rotation to the right began again, and when lifting his hat in the street to salute a friend, he repeated the movement. At table, too, he noticed it as he was in the act of bringing his glass to his mouth. P. is consequently upset, and often plunged into tears.

December 24.– The patient's condition is more than ever deplorable. On the slightest provocation – indeed, on no provocation at all – furious torsion movements force the head backwards and to the right, while the right shoulder rises.

Complete rest in bed was ordered, yet after two or three days of this repose the torticollis manifested itself even in the recumbent position. As a result, he was quite unnerved and talked of suicide. Another physician called in consultation agreed with what had been done, confirmed the integrity of all the reflexes, including the plantars, and recommended a course of electricity.

January 20, 1902.– There has been no further change. P. stays abed all morning, inventing endless arrangements of pillows and dictionaries to prop his head. When he goes out for a walk, he turns up the collar of his coat and leans his head on the point of it.

January 27.– The electrical treatment has been relinquished. He has also taken one douche at a hydrotherapeutic establishment, but expressed his dissatisfaction and vowed never to return. He then departed to undergo a "water cure" in the country, since when he has vanished entirely from observation.

More than once we have had occasion to notice that the degree and extent of such neck and arm convulsions as are provoked or exaggerated by the act of writing vary with the level at which the patient has to write. With elevation of the arm the movements are weak and easily mastered; conversely, lowering of the arm augments them in a marked manner. We repeat, however, that in all these cases the handwriting itself is not interfered with.

It is quite otherwise with writers' cramp, the so-called "graphospasm" or "mogigraphia." This condition is purely and exclusively a disorder of the function of writing, depending for its exhibition on the exercise of this function, else is its existence concealed. For this reason it ought to be differentiated from the tics, although, by its development in obvious neuropathic or psychopathic subjects, it is closely linked to them.

One of Oppenheim's cases was a lady whose husband suffered from paralysis agitans; in her case, fear of becoming affected with the same disease led to the development of writers' cramp. Sometimes it occurs in families, and it may be a concomitant of genuine tics. In spite of the affinity between these two sorts of functional disturbance, we do not feel it incumbent on us to enter on a detailed study of scriveners' palsy in this place.
