Tics and Their Treatment. Feindel Eugène

his friendships and enmities – there is commonly a disproportion about them that betokens mental deficiency. At one time it is fear or repulsion that actuates him; at another it is an unnatural tenderness, a sort of philia, if the term may be allowed.

      Anomalies such as these, however, are met with in all the mentally unstable, and do not present any special feature when they occur in those who tic.

      An acquaintance with the mental state of our patients enables us to understand the mode their tic adopts. As one thinks, so does one tic. To the transiency and mutability of the child's ideas correspond what are known as variable tics, which rarely have a definite localisation, and become fixed only when certain ideas become preponderant. The existence of a solitary tic, however, is not at variance with that disposition we have qualified as infantile, for mental infantilism is the original stock; on it, as a matter of fact, may be grafted further mental disorders in the shape of fixed ideas, phobias, or obsessions.

      Should a fixed idea entail a motor reaction, it may give rise to a tic as ineradicable as the idea itself, and a series of fixed ideas may be accompanied by a succession of corresponding tics.

      The frequency with which obsessions, or at least a proclivity for them, and tics are associated, cannot be a simple coincidence. Without defining the word obsession, let us be content to recall the excellent classification given by Régis, according to whom they mark a flaw in voluntary power, either of inhibition or of action. On the one hand we have impulsive obsessions, subdivided into obsessions of indecision, such as ordinary folie du doute; of fear, such as agoraphobia; of propensity, such as those of suicide or homicide. On the other we find the aboulic obsessions, such as inability to stand up (ananastasia), or to climb up (ananabasia), or the astasia-abasia of Séglas, or the akathisia of Haskowec. Perhaps we ought also to place here sensory obsessions in the shape of topoalgia, and even hallucinatory affections.

      In all these varieties of obsession increase or diminution of volitional activity is undeniable. But this alteration in the function of the will is no less distinctive of tic, and if we compare the psychical stigmata of obsessional patients – the asymmetry of their mental development, their intellectual inequalities and lack of harmony, their alternating excitability and depression, their unconventionalities, eccentricities, and imaginativeness, their timidity, whimsicalness, sensitiveness, and all the other indications of a psychopathic constitution – if these are compared with the mental equipment of the sufferer from tic, we cannot but notice intimate analogies between the two, analogies corroborated by a glance at their symptomatology.

      An obsession may be of idiopathic origin, or it may be causally connected with some particular incident, sensation, or emotion. A conflagration may determine fear of fire, or a carriage accident amaxophobia. Further, the obsession is irresistible, as is the tic: opposition endures but for a moment, and is therefore vain. Nor is the inhibitory value of attention or distraction any less ephemeral. This feature of tic was noted as long ago as 1850 by Roth, who held its motor manifestations to be phenomena of "irresistible musculation."

      Consciousness is maintained in its integrity both before and after, but not during, an obsessional attack, and this is equally true of tic, as are the preliminary discomfort and subsequent satisfaction that attend the obsession. Noir makes the appropriate remark that idiots affected with krouomania, in whom sensory disturbance is awanting, so far from suffering pain through sundry self-inflicted blows and mutilations, seem, on the contrary, to be thus afforded a certain feeling of relief, if not of actual relish.

      Whenever Lam., who exhibits incessant balancing and rotatory movements of the head, is seated in proximity to a wall, he knocks his head sideways against it until a bruise results, and appears to find therein a source of genuine satisfaction.24

      If, then, an obsession provokes a motor reaction at all, it may originate a tic, and, in the case of tonic tics, this is a very common mode of derivation, as one may well understand how an obsession may occasion an attitude.

      Grasset cites the example of a young girl who would never lean backwards in a railway carriage or on any chair or bench, preferring to sit bolt upright on the edge. In this instance the adoption of a stereotyped attitude was directly attributable to an obsession.

      Another example of an attitude tic is furnished by the case of young J.:

      Standing or seated, he always has his half-flexed left arm firmly pressed against the body in the position assumed by hemiplegics. Its pose and inertia and the awkwardness of its movements unite to suggest some real affection, the existence of which the constant use of the right arm and the elaboration by the patient of intricate devices to obviate disturbing the other tend to substantiate. Nevertheless, the impotence is entirely imaginary. To order he can execute any movement of the left arm with energy and accuracy; his left hand will button or unbutton his clothes, lace his boot, handle a knife, and even hold a pen and write.

      It seems that the position of the arm was chosen deliberately to alleviate a supposed pain in the shoulder, and unceasing resort to this subterfuge of his own inventing, which he considered a sovereign remedy, ended in its voluntary adoption being succeeded by its automatic reproduction.

      The assumption of this position for his arm was at first attended with satisfactory results, but, as might have been foreseen, its inhibitory value decreased gradually, so he had recourse to other means. It was then that the right hand was made to grip the left and press it more energetically than ever against the epigastrium. In this complex attitude both arms simultaneously participated, but again its efficacy was purely transitory. Evidently dissatisfied with his methods of immobilisation, and convinced that experimentation would end in the discovery of the desired arrangement, J. proceeded to employ the right hand in impressing every variety of passive movement on the left hand, wrist, forearm, and upper arm, and soon there was no checking these gymnastic exercises. He would suddenly grasp the wrist and pull and screw it, while the left shoulder and elbow resisted nobly; or he would bend, or unbend, or twist his fingers, or seize the arm below the axilla and knead it or rub it, forcing it against or away from the thorax; he would pound the muscles and pinch the tendons, sometimes in a brutal fashion; in short, the situation degenerated into nothing more nor less than a pitched battle between the left arm and the right hand, in which the latter endeavoured by a thousand tricks to bring the former into subjection. Victory rested always with the affected arm.

      Each time that this absurd combat recommenced, the patient experienced a sensation of relief; resignation to the imperious motor obsession was even followed by a sense of well-being. On the other hand, resistance was accompanied by actual anguish – he would fidget desperately in his chair, cross and uncross his legs, sigh, grimace, rub his eyes, bite his lips and nails, twist his mouth about, pull at his hair or his moustache, he would look anxious or alarmed, would become by turns red or pale, and beads of perspiration would gather on his face. At length he would be compelled to yield, and the bloodless battle of his upper limbs would close more furiously than ever.

      In this case the typical features of obsession are excellently illustrated – its irresistibility, as well as the concomitant distress and succeeding content.

      Conversely, however, a tic may be said to develop into an obsession if the exciting cause of the latter be the motor reaction.

      In various psychopathic conditions (says Dupré25), especially where the genito-urinary apparatus is concerned, this pathogenic mechanism is encountered. Some source of peripheral irritation in bladder, urethra, prostate, etc., provokes cortical reaction, and a reflex arc is established with centrifugal manifestations in the guise of motor phenomena, which in their turn originate all sorts of fixed ideas, impulsions, and obsessions, forming an integral part of the syndrome.

      There is frequently no direct or obvious connection between a patient's obsession or obsessions and his tics. The former may consist, both in children and in adults, in extraordinary scrupulousness, perpetual fear of doing wrong, absolute lack of self-confidence, sometimes simply in excessive timidity, exaggerated daintiness, or interminable hesitation. We have often seen youthful subjects betray in their disposition weak elements such as the above, which at a later stage have proved the starting-point for more definite obsessions. Their intelligence and capacity for work earn the approbation
