Tics and Their Treatment

by Henry Meige; E. Feindel

Here is another patient: his habits of continually washing his hands, of expectorating as he passes any one, have their explanation in his dread of being poisoned by imaginary foes, and, though subsequent mental disintegration precludes the possibility of the delusion continuing, the trick remains to the end of life.

A case has been put on record by Wille,[27] under the name of "disease of impulsive tics," concerning a young man twenty-two years of age, who, in addition to the grave taint of a psychopathic heredity, exhibited early indications of irritability and a tendency to obsessions. Systematised movements of face, shoulders, and arms, accompanied with coprolalia, were not long in appearing. It was noticed that the psychical symptoms were periodic, and that their nocturnal exacerbation coincided with the advent of hallucinations. Two attacks of mania came on, but a cure followed after four years' time.

It may be questioned whether we are not dealing here with a case of dementia præcox, rather than with the true Gilles de la Tourette's disease; at any rate, tic may be a concomitant of grievous mental affections.

Another case of still more advanced mental deterioration may be quoted from Bresler:[28]

In this patient contractions of facial and limb musculature at the age of nine were succeeded by some years of epileptic outbreaks; and outrageous conduct towards his mother and sister, coupled with acts of wanton brutality and destruction, at length necessitated his removal to an asylum. He suffers from convulsive tic of face and shoulders, while his speech is drawling and syllabic, and interrupted by guttural ejaculations corresponding to the manifestations of his tic.

It is superfluous to dilate further on this part of our subject, and we shall take another opportunity of dealing with the question of tics in idiots and the mentally backward. For the present, the statements of the chapter may be summarised in a few words:

In the mental condition of the subject of tic there may be differentiated two elements: the one is fundamental, and is sufficiently described in the phrase mental infantilism; the other is superadded, and consists of a multiplicity of psychical imperfections which reveal, at the same time as they exaggerate, the inherent defects constituting the former, in particular volitional infirmity. By this means a useful clinical distinction may be drawn between various tics, according as they take their rise in one or other form of mental affection, and at the same time the practical gain is considerable, for treatment must be directed both to the physical and the psychical aspect of the malady, and its success in the former sphere is greatly dependent on intelligent recognition of and acquaintance with the nature of the latter.

Manias, obsessions, phobias, and other accompaniments of the disease known as tic (says Grasset)—those abnormal phenomena that testify to the affection as the stigmata of hysteria confirm that neurosis—are nothing more than psychical tics; that is to say, special types of the disease. If their occurrence is frequent and indeed habitual, their absence in no way invalidates the diagnosis. They resemble coprolalia, salutations, etc., in being accidental and not essential symptoms.

We are entirely at one with Grasset on this last point; but if they do occur, are they to be denominated tics? We must beg to be excused for dwelling with such insistence on a question of words, but we are assured that the rigorous limitation of the word tic to conditions in which it is possible to recognise two inseparable and indispensable elements, one motor and the other mental, cannot fail to simplify matters. Otherwise, of course, we are merely adding to the meaning of a term already interpreted in far too liberal a fashion.

Abuse of language such as this leads to inevitable confusion. Noir, for an instance, in whose excellent thesis there is abundant evidence of painstaking observation and judicious discernment, is constrained to write:
