Tourette s is defined as part of a spectrum of tic disorderswhich includes transient and chronic tics.
Tourette s was once considered a rare and bizarre syndromemost often associated with the exclamation of obscene words or socially inappropriate and derogatory remarks coprolaliabut this symptom is present in only a small minority of people with Tourette s. Between 1 and 10 children per 1, have Tourette s; [ 2 ] as many as 10 per 1, people may have tic disorders, [ 3 ] [ 4 ] with the more common tics of eye blinking, coughing, throat clearing, sniffing, and facial movements.
People with Tourette s have normal life expectancy and intelligence. The severity of the tics decreases for most children as they pass through adolescence, and extreme Tourette s in adulthood is a rarity. Notable individuals with Tourette s are found in all walks of life. In most cases, medication is unnecessary.
Explanation and reassurance alone are often sufficient treatment; [ 6 ] education is an important part of any treatment plan.
Tourette s is one of several tic disorderswhich are classified by the Diagnostic and Statistical Manual of Mental Disorders DSM according to type motor or phonic tics and duration transient or chronic. Transient tic disorder consists of multiple motor tics, phonic tics or both, with a duration between four weeks and twelve months.
Chronic tic disorder is either single or multiple, motor or phonic tics but not bothwhich are present for more than a year. Waxing and waning—the ongoing increase and decrease in severity and frequency of tics—occurs differently in each individual.
Tics also occur in “bouts of bouts”, which vary for each person. Individuals describe the need to tic as a buildup of tension, pressure, or energy [ 19 ] [ 20 ] which they consciously choose to release, as if they “had to do it” [ 21 ] to relieve the sensation [ 19 ] or until it feels “just right”. The actual tic may be felt as relieving this tension or sensation, similar to scratching an itch.
Another example is blinking to relieve an uncomfortable sensation in the eye.

These urges and sensations, preceding the expression of the movement or vocalization as a tic, are referred to as “premonitory sensory phenomena ” or premonitory urges. Because of the urges that precede them, tics are described as semi-voluntary or ” unvoluntary “, [ 13 ] rather than specifically involuntary ; they may be experienced as a voluntarysuppressible haloeridol to the unwanted premonitory urge. Children may be less aware of the premonitory urge associated with tics than are adults, but their awareness tends to increase with maturity.
Children may suppress tics while in the doctor s office, so they may need to be observed while they are not aware they are being watched. Although there is no such thing as a “typical” case of Tourette syndrome, [ 6 ] the condition follows a fairly reliable course in terms of the age of onset and the history of the severity of symptoms.
Tics may appear up to the age of eighteen, but the most typical age of onset is from five to seven. Initial tics present most frequently in midline body regions where there are many muscles, usually the head, neck and facial region.
Causes and origins of Tourette syndrome Extrapirzmidalismo artigo principal: Fxtrapiramidalismo gene s may express as Tourette s, as a milder tic disorder transient or chronic ticsor as obsessive—compulsive symptoms without tics. Only a minority of the children who inherit the gene s have symptoms severe enough to require medical attention. Ina team at the US National Institute of Mental Health proposed a hypothesis that both obsessive—compulsive disorder OCD and tic disorders may arise in a subset of children as a result of a poststreptococcal autoimmune process.
Tics are believed to result from dysfunction in cortical and subcortical regions, the thalamusbasal ganglia and frontal cortex. The previous DSM-IV included a requirement for “marked distress halooeridol significant impairment in social, occupational or other important areas of functioning”, but this requirement was removed in the extrapiramidalis,o recent update of the manual, in recognition that clinicians see patients who meet all the other criteria ahloperidol Tourette s, but do not have distress or impairment.
There are no specific medical or screening tests that can be used in diagnosing Tourette s; [ 22 ] it is frequently misdiagnosed or underdiagnosed, partly because of the wide expression of severity, ranging from mild the majority of cases or moderate, to severe the rare, but more widely-recognized and publicized cases.
An example of this is when diagnostic confusion between tics and seizure activity exists, which would call for an EEGor if there are symptoms that indicate an MRI to rule out brain abnormalities. Brain imaging studies are not usually warranted. If a family history of liver disease is present, serum copper and ceruloplasmin levels can rule out Wilson s disease.
Other possibilities include chromosomal disorders such as Down syndromeKlinefelter s syndromeXYY syndrome and fragile X syndrome. Acquired causes of tics include drug-induced tics, head trauma, encephalitisstroke. Children and adolescents with TS who have learning difficulties are candidates for psychoeducational testing, particularly if the child also has ADHD.
Complications may include depressionsleep problemssocial discomfort and self-injury. Treatment of Tourette syndrome Ver artigo principal: The treatment of Tourette s focuses on identifying and helping the individual manage the most troubling or impairing symptoms. There is no cure for Tourette s and no medication that works universally for all individuals without significant adverse effects.
Knowledge, education and understanding are uppermost in management plans for tic disorders. While pharmacological intervention is reserved for more severe symptoms, other treatments such as supportive psychotherapy or cognitive behavioral therapy may help to avoid or ameliorate depression and social isolation, and to improve family support.
Educating a patient, family, and surrounding community such as friends, school, and church is a key treatment strategy, and may be all that is required in mild cases. Haloperidol is an antipsychotic medication sometimes used to treat severe cases of Tourette s. Rxtrapiramidalismo is available to help when symptoms interfere with functioning.
Drugs from several other classes of medications can be used when stimulant trials fail, including hzloperidol trade name Tenexatomoxetine Strattera and tricyclic antidepressants.
Clomipramine Anafranila tricyclic, and SSRIs —a class of antidepressants including fluoxetine Prozacsertraline Zoloftand fluvoxamine Luvox —may be prescribed when a Tourette s patient also has symptoms of obsessive— compulsive disorder.
Several other medications have been tried, including nicotine patchesbut evidence to support their use is unconvincing. The majority of cases are mild and require no treatment. The overall prognosis is positive, but pir minority of children with Tourette syndrome have severe symptoms that persist into adulthood. Although the symptoms may be lifelong and chronic for some, the condition is not degenerative or life-threatening. Intelligence is normal in those with Tourette s, although there may be learning disabilities.
The gene or genes associated with Tourette s have not been identified, and there is no potential “cure”. Tics may be at their highest severity at the time that they are diagnosed, and often improve with understanding of the condition by individuals and their families and friends. The statistical age of highest tic severity is typically between eight and twelve, with most individuals experiencing steadily declining tic severity as they pass through adolescence.
One study showed no correlation with tic severity and the onset of puberty, in contrast with the popular belief that tics increase at puberty. In many cases, a complete remission of tic symptoms occurs after adolescence. Half of the adults who considered themselves tic-free still displayed evidence of tics. Because Tourette s tends to subside with maturity, and because milder cases of Tourette s are extrapiramidalism more likely to be recognized, the first realization that a parent had tics as a child may not come until their offspring is diagnosed.
It is not uncommon for several members of a family to be diagnosed together, as parents bringing children to a halo;eridol for an evaluation of tics become aware that they, too, had tics as a child.
It doesn t affect me one way or another on or off the field. If a child has disabling tics, or tics that interfere with social or academic functioning, supportive psychotherapy or school accommodations can be helpful. Accomplished musicians, athletes, public speakers, and professionals from all walks of life are found among people with Tourette s. Outcomes in adulthood are associated more with the perceived significance of having severe tics as a child than with the actual severity of the tics.
A person who was misunderstood, punished, or teased at home or at porr will fare worse than children who enjoyed an understanding and supportive environment. Most cases would be mild and almost unrecognizable in older individuals.
Other comorbid conditions include self-injurious behaviors SIBanxietydepressionpersonality disordersoppositional defiant disorderand conduct disorders. History of Extrapiramisalismo syndrome Ver artigo principal: Shapiro —described as “the father of modern tic disorder research” [ 84 ] —treated a Tourette s patient with haloperidol, haloperirol published a paper criticizing the psychoanalytic approach.
Questions remain regarding how best to classify Tourette syndrome, and how closely Tourette s is related to other movement disorders or psychiatric disorders. Good epidemiologic data is still lacking, and available treatments are not risk free and not always well tolerated. Sociological and cultural aspects of Tourette syndrome Ver artigo principal: Samuel Johnson poe volta de Johnson likely had Tourette syndrome. Not everyone with Tourette s wants treatment or a “cure”, especially if that means they may “lose” something else in the process.
The bestknown example of a person who may have used obsessive—compulsive traits to advantage is Samuel Johnsonthe 18th-century English extrapidamidalismo of letters, who likely had Tourette syndrome as evidenced by the writings of James Boswell.
Although it has been speculated that Mozart had Tourette s[ 93 ] [ 94 ] no Tourette s expert or organization has presented credible evidence to support such a conclusion, [ 94 extrapiramiddalismo and there are problems with the available data.

The extrapigamidalismo said dxtrapiramidalismo also found a correlation between the extent of some of the structural changes they identified and symptom severity. The researchers said they identified alterations in the frontal lobe of the Tourette s patients that might be responsible for the pathology of the syndrome. MTI, the scientists said, is a refinement of the nuclear magnetic resonance technique, allowing detection of changes invisible to conventional MRI scanners.
The imaging technology discovered alterations, in comparison to controls, in brain areas involved in the selection, programming, initiation and control of movement. The study appears in the journal BMC Neuroscience. O estudo aparece no jornal BMC Neuroscience.
