VASOMOTOR AND SECRETORY AFFECTIONS
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. It is even conceivable that fear of blushing—the ereutophobia of Regis—may be at the bottom of certain gestures intended to conceal the heightened colour the apparition of which is so humiliating. The form they assume is generally a movement of the arm or hand over the face, to mask the momentary discomfort, and while in most instances they are no more than stereotyped acts, they may develop into full-blown tics.
In regard to secretory affections, we have frequently observed the concurrence of hyperidrosis and emotional phenomena in those who tic. Young J., S., P., are cases in point. The slightest exertion, the least effort of attention, are followed by an extraordinary secretion of sweat, entailing constant carrying of a handkerchief in the hand, and ceaseless mopping of the forehead or temples. This performance becomes stereotyped, and is gone through even when there is no perspiration at all. Suppression of the handkerchief sometimes causes actual malaise, but this injunction must never be forgotten if a cure is to be effected.
[Persons afflicted with tic often develop a sort of visceral instability which betrays itself in indigestion, dyspepsia, constipation, diarrhœa, and in every variety of dietetic and alimentary caprice.
It is rare to meet with troubles of micturition, nocturnal enuresis scarcely deserving mention owing to its frequency among all young degenerates and to its being so commonly the outcome of neglect. Oppenheim,[58] however, considers diurnal enuresis worth including in the symptomatology, and Brissaud[59] has described polyuria and pollakiuria in association with obsessional preoccupation. These are really functional disturbances in which increased desire is followed by increased vesical action, and may be regarded, if one likes, as micturition or sphincter tics.[60]]
