Tics are abnormal movements, involuntary, sudden, repeated always equal with variable frequency, these are movements that can be played voluntarily (because they imitate the tics are), but they, Unlike the voluntary acts do not appear to direct a purpose, a purpose, but are entirely unjustified and unnecessary. Tic involuntary: they may however be influenced by the will and, in particular eliminated, at least temporarily: the effort needed to remove them, moreover, often leads to the onset of an anxiety state that can be solved only with the implementation of ICT, as if the individual can not help but to do it for some sort of mechanism obsessive. Usually, however, the tick does not appear the result of an impulse or obsessive compulsive (ie, an impulse to do precisely what the movement ticcoso, from which the individual feels 'obliged', dominated and fought vainly against which to check) but are rather the character of an automatic action that takes place that is completely outside intervention the will and is therefore not experienced as something that you have to do, but as an act that takes place in itself, automatically, regardless of any conscious control of vqlontà. In addition to voluntary effort, some people manage to suppress their tics, but always only temporarily, using special tricks in that, in general, the performance of particular movements opposed to those ticcosi (eg strongly bend the head forward , tighten your fist, etc.)..
DIFFERENT TYPES OF ICT
Tics can be very different and, in the same person, present singly or variously associated with each other. The most common are those observable to the face where they can be, for example, in movements such as winks, frowning, grimacing faces and, biting or licking their lips, open mouth, protrude the tongue, etc.
. Often, as said, these tics are associated with each other and then they are of particular facial expressions (disgust, anger, etc.).. It is not uncommon that occur in the form ticcosa acts, such as issuance of special sounds through the mouth, the burping, coughing, throat clearing, spitting, etc.. There are also verbal tics, consisting in general of obscene or insulting words (in the latter case we speak of coprolalia), or curses, which are repeated intermittently in the context of a normal conversation. Common tics are movements of the head consisting of greeting, affirmation and denial. limb tics can take the most diverse aspects: raising of the shoulders, shaking of the arms, hands closed in a fist, finger opening a fan, scratching genuflections, hops, etc. .
fatigue and emotions exacerbate tics, but that diminish with rest and when the subject is engaged in occupations that absorb fully, during sleep, then disappear altogether. Tics can occur at any age but are most common in children especially in the age of adolescence.
CAUSES
What tics are due? There are two theories that are opposed to each other: on the one hand it is argued that the tick is due to psychological causes, injury to other anatomical system nervoso.L 'depth studies led to recognize a bit' of reason to both theories and the current design, one that is at least more widely accepted, psychological and physical factors (organic) are considered to participate together, albeit with a prevalence varying from case to case, the realization of the phenomenon ticcoso. Indeed, apart from the cases, relatively rare, in which the tick is secondary to impairment of certain anatomical structures of the brain (the striatum in particular) or where it is a symptom of a mental disorder (schizophrenia, hysteria), the movement ticcoso, a detailed analysis, it is revealed as the result of action of many factors but basically, we can reduce to two On the one hand the preparation (both mental and physical) of the other occasional causes of action, ie independent constitutional factors.
But what is the arrangement? What are these occasional causes? With regard to the issue, it should be a separate physical or, rather, a psychic and motor.
The first is represented by a restlessness, a kind of instability and disorder of of voluntary muscles, is what is observed in some children who do not stand still for a moment, constantly needing to move, to touch and do something: their exuberance motor exceeds that which is the vivid (and seems to be back in oetanei delayed development of the nervous
regulators of motility in these guys would be the tick, in a sense, the means by which you download the Constitutional motor hyperactivity.
The second, psychological preparation, is in a state of mind characterized hyperexcitability, irritability, exaggerated emotion, often detectable signs are also more or less tinged with obsessive personality (Individuals scrupulous, meticulous, superstitious, and the trend continued to doubt, to manifestations of phobic and when the tick takes in the light of psychoanalytic interpretations, the meaning of a symbolic expression of unconscious aggression) are not really rare in ticcosi known eccentricity and weirdness.
This dual arrangement is the basis on which they can enter, triggering the tics, the more casual variety of causes: fatigue, for example, or the intense emotions, may also have considerable importance neurotic type reaction to an overly rigid attitude of educating parents In these cases, the tick may take the meaning of a gesture of protest. It

Tics can occur in episodic form, then to resolve completely with the removal or mitigation or removal of the causes that they have triggered occasional, or to achieve greater maturity and a better overall balance both physical and psychic (it This is the case with many tics of adolescents who end up just to disappear spontaneously, on their own). In other cases, the tic persists, tenacious, for a long time and maybe for life. There are also
tic variables that occur only in relation to particular environmental situations: at school, for example, or family.
must also be reminded of the tic disease of Gilles de laTou-lines, their teenagers, in which movements are ticcosi intense, serious, extended to the whole body and accompanied by coprolalia (ie, the continuous repetition of obscene words).
