Tourette Syndrome
Overview
Tics are very common – about 1 in every 4 children will have a short-lived tic or set of tics during their childhood. Tics are best thought of as repeated (“stereotyped”) patterns and non-rhythmic, non-soothing movements or noises that serve no functional purpose. However, for some children, tics endure for long periods of time.Tourette syndrome (TS) is a type of tic disorder characterized by waxing and waning motor and phonic (often vocal) tics lasting over a year (although not necessarily at the same time). Chronic tic disorders – chronic motor tic disorder, chronic vocal tic disorder, and TS – are differentiated by the types of tics (motor, vocal/phonic, or both). Because the distinctions among TS and the other two are generally accepted as artificial, the term TS will be used to refer to all of them in the following discussion. Chronicity (lasting a year or more) distinguishes TS from provisional tic disorder, the duration of which is less than 1 year (determined retrospectively or currently).
In TS, motor and phonic tics range in their expression from simple to complex. Simple motor tics are brief and involve an isolated muscle group, such as an eye blink, while complex motor tics appear more purposeful, such as the holding of a posture or moving multiple muscle groups in sequence to jump or twirl. Complex motor tics may include copropraxia, involving vulgar gestures or other socially inappropriate actions, such as suddenly reaching for or touching another person inappropriately.
Simple phonic tics involve sudden meaningless noises, such as sniffing or grunting, while complex phonic tics sound language-based, such as echolalia (repeating vocalizations made by another person) or coprolalia (uttering socially inappropriate language). Despite frequent media portrayal, copropraxia and coprolalia are uncommon among people with TS.
By adolescence, most people with TS can describe an uncomfortable physical sensation or urge that precedes a tic. The performance of the tic or tics temporarily reduces this urge. Although most individuals with TS are able to suppress their tics temporarily, the urges usually persist and build, becoming so intolerable that the tics are ultimately expressed. Stress, anxiety, excitement, and fatigue may increase tic frequency and intensity.
Tic disorders reflect a complex underlying ‘leaky filtering’ of sensory inputs or ‘disinhibition,’ characterized by inconsistent ability to inhibit certain thoughts, emotions, or behaviors. Most people diagnosed with TS will also have one or more non-tic associated conditions, including attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, learning problems, sleep disorders, depression, or sudden excessive outbursts of anger. Signs and symptoms of these comorbid conditions can precede, co-occur with, or follow the onset of tics. These conditions usually pose a greater risk to the neuro-developmental, psycho-social, and behavioral well-being of the child than the tics alone pose. Adverse consequences of TS on self-esteem, academic performance, and social flexibility are common and can be profound.
Many lines of evidence link TS with pathways between the prefrontal cortex, the thalamus, and the basal ganglia and changes in the distribution and activity of the neurotransmitter dopamine. For example, medications that decrease tics (including the antipsychotics haloperidol and pimozide) are known to alter traffic through these pathways, and data from functional imaging of individuals with TS support these neurophysiological mechanisms. [Butler: 2006] Also, deep brain stimulation to specific suspected brain regions appears helpful in some people with refractory TS. [Bajwa: 2007]

Prevalence
The prevalence of TS in children is approximately 0.5 percent (1:200). [Scharf: 2015] Males are 3 to 4 times more likely than females to have TS. [Knight: 2012] Related chronic tic disorders (either motor or vocal, but not combined) are 3 to 4 times more common than TS. Short-lived tics lasting less than 1 year (provisional tic disorders) occur in up to 1:4 children, usually during the first decade of life.Genetics
The causes of TS are poorly understood; genetic and environmental factors influence variations in the expression of tics and associated conditions.Prognosis
Many people with TS adapt well to tics and neither seek nor require treatment. Tics are likely to decrease or resolve in late adolescence. [Hassan: 2012] Associated conditions, such as ADHD and OCD, may be lifelong; symptoms vary with developmental stages.Practice Guidelines

Roles of the Medical Home
Most children with TS can be followed within their medical home with periodic surveillance and targeted screening for problems related to tics and associated conditions. Depending on the provider’s comfort with the diagnosis, the severity of TS and associated conditions, and if a medication trial is being considered, evaluation by a TS specialist may be appropriate. When indicated, the medical home coordinates care and ensures communication among a team that could include a psychologist and other school-based professionals, and depending on local availability, a neurologist, psychiatrist, or developmental-behavioral pediatrician. The Portal's Education & Schools section for clinicians can help guide communications with teachers and school personnel to ensure that patients receive appropriate education-related services.Keeping a Care Notebook can help families maintain continuity of care. Ongoing education and support for the child, family, peers, and educators are critical. The Tourette Association of America has a Youth Ambassador Program (Tourette Association) and provides explanations of protections under the Individuals with Disability Education Act (IDEA) and "Section 504" of the Americans with Disabilities Act. Parents may also find helpful information about school services and laws in the Portal's Education and Schools family's section. Effective child advocacy and self-advocacy depend on positive regard and solid self-esteem.
Clinical Assessment
Overview
Assessment of an individual with a suspected tic disorder should include a thorough medical history and physical exam. These will ideally include assessment of tics and their impact on academic, social, organizational, family, and health. Careful questioning for frequently co-existing conditions is critical. The relative impact of co-existing factors on self-esteem and quality of life should be defined.Pearls & Alerts for Assessment
Tic occurrenceTics wax and wane over time and emotional states can influence tics.
Severity‘Tic severity’ is not a single thing but is determined by several features (number, intensity, frequency, complexity, functional interference, and distress).
Co-existing conditionsExpect 1 or more co-existing non-tic conditions (e.g., ADHD, OCD, academic difficulties, anger outbursts, anxiety). Their presence is the rule rather than the exception.
Screening
For Complications
Surveillance/screening should be conducted for associated behavioral problems, such as:- ADHD (~50%) - for screening tools, see Attention Deficit Hyperactivity Disorder (ADHD), Initial Diagnosis
- OCD (~30%)
- Anxiety (~30%) - for screening tools, see Anxiety Disorders, Initial Diagnosis
- Learning problems (~20%)
- Sleep problems
- Depression - for screening tools, see Depression , Initial Diagnosis
- Anger control difficulty
- Autistic disorder
Presentations
The tics in TS typically emerge when a child is 4 -7 years of age. The tics may evolve from simple to complex and from just motor to motor and/or phonic. Associated behavioral or neurodevelopmental conditions may precede, occur with, or begin after the tics have emerged.Diagnostic Criteria
No test confirms the diagnosis of TS. Note that tic disorders less than 1 year in duration are provisional, as the diagnosis cannot be made until the tics have been present for 1 year. The following criteria from the DSM-5 [American: 2013] must be met to make a diagnosis of TS (referred to as Tourette's Disorder in DSM-5):- Both multiple motor and 1 or more vocal tics have been present at some time, although not necessarily concurrently (a tic is a sudden rapid, recurrent, nonrhythmic motor movement or vocalization)
- Tic frequency may wax and wane but have persisted for more than 1 year since first tic onset
- Onset is before age 18 years
- Disturbance is not attributable to the physiological effects of a substance (e.g., cocaine) or another medical condition (e.g., Huntington's disease, post-viral encephalitis).
Differential Diagnosis
Other tic disorders: See introductory discussion regarding lack of relevant clinical distinction among the chronic tic disorders in childhood.Stereotypies are repetitive, rhythmic, soothing movements, postures, or utterances. Although they are often seen in children with autism spectrum disorder, they are also very common in typically developing children. Stereotypies usually emerge prior to 3 years of age. Examples include hand-flapping, rocking, and twirling. Among children with communication limitations, stereotypies and complex tics may be indistinguishable.
Habits share features with stereotypies but typically are not rhythmic or soothing and may be quick behaviors that can be reinforced through repetition. Examples include nail-biting and lip-licking.
Compulsions are very similar to tics and sometimes difficult to distinguish from complex tics. Compulsions usually are responses to obsessive thoughts, whereas tics usually are responses to sensory experiences.
Seizures: Generalized seizures are accompanied by a loss of consciousness, while complex partial seizures are associated with alterations in consciousness and responsiveness. Some partial seizures could be mistaken for tics, but these are generally not suppressible and are not preceded by a premonitory urge. Eyelid flickering (myoclonus) seen with absence seizures could resemble tics, but in absence seizures, there is loss of consciousness, no ability to suppress the seizure, and no premonitory urge.
Substance exposure: Neuropsychiatric medications are unlikely to cause tics, but they can be associated with other movement problems, such as restlessness. Stimulant medications do not cause tics; in a fraction of patients, the medication exacerbates them. Tics have been reported with carbamazepine and rarely other medications. Prolonged use of some neuroleptics may result in tardive dyskinesia, a neurologic syndrome with a variety of repetitive purposeless movements that may appear tic-like. Movements may occur in the extremities, as well as the face and could include lip-smacking, grimacing, and rapid eye-blinking. Medication adjustments are usually necessary when tardive dyskinesia is noted.
Muscle spasms, such as blepharospasms or spasmodic torticollis, may be confused with TS, but the characteristics of tics in TS should allow differentiation.
Sydenham chorea is a neurological disorder of childhood resulting from an autoimmune reaction to infection group A beta-hemolytic Streptococcus (GABHS), which also causes rheumatic fever. This condition is characterized by involuntary movements of the face, arms, and legs, clumsiness, emotional volatility, difficulty concentrating, and no premonitory urge. Sydenham chorea is typically seen in children 5-15 years old. It affects girls more than boys and may appear from several weeks to many months after strep infection. There is no treatment; the chorea usually resolves after weeks to months. Symptomatic management of chorea is rarely necessary.
Post-viral encephalitis: This brain-based inflammation is differentiated from tics by medical history and examination.
Pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) is a controversial condition postulated as either 1) a dramatic increase in symptoms in children already known to have tics or OCD or 2) an appearance of such symptoms in children without prior history, following a GABHS infection, other infection, or non-infectious suspected causes. [Blackburn: 2018] PANS – or pediatric acute-onset neuropsychiatric syndrome – has been coined as a broader term to include other infectious and non-infectious suspected causes. [Wilbur: 2019] No diagnostic criteria are uniformly accepted as definitive for this hotly debated condition. There is quite a bit of intrigue and controversy, and research is ongoing. [Chang: 2015]
Wilson disease is an autosomal recessive genetic disorder that prevents the body from disposing of extra copper. As copper levels build in the brain, tremor and tic-like movements, incoordination of speech, swallowing, and gait, and behavioral changes can occur. If the liver is also involved, jaundice, ascites, and other systemic symptoms may be present. Physical exam findings also include Kayser-Fleischer rings due to copper accumulation in the eye. Laboratory findings show decreased copper and ceruloplasmin levels in the blood, increased urinary excretion of copper, and copper accumulation in the liver. Since Wilson disease is treatable, there should be a low threshold for medical screening for this disorder.
Comorbid & Secondary Conditions
More than 90% of individuals with TS have 1 or more associated behavioral or neurodevelopmental conditions. Onset of the signs and symptoms of these co-existing conditions can precede, co-occur with, or follow the onset of the tics. These conditions may include:| ADHD (~50%) | Fine motor coordination difficulty |
| Obsessions and Compulsions (>50%) | Specific learning disability (~ 20%) |
| Anxiety (~30%) | Autism spectrum disorder |
| Depression | Sleep problems |
| Anger control difficulty | Executive function difficulties |
History & Examination
Current & Past Medical History
Phonic tics such as sniffing or coughing may be confused with allergies. Likewise, eye-blinking is often attributed to allergies and eye irritation. For patients with known TS, tic severity (which may be determined by frequency, complexity, intensity, number, interference with social experience and functions in life, and discomfort or pain) should be monitored in ongoing visits. For patients taking medications to reduce tics, track effectiveness, side effects, and the need for ongoing treatment.Family History
A family history of TS, OCD, ADHD, or learning problems is common; however, 10% of children with TS have no identifiable contributory family history.Pregnancy/Perinatal History
Maternal cigarette smoking during pregnancy may increase tic severity in children predisposed to developing TS.Developmental & Educational Progress
As with all children, social, academic, mood-based, and other functional symptoms should be a part of periodic routine screening. If concerns arise, a comprehensive psycho-educational assessment is usually indicated. Open-ended questions about academic, social, organizational skills, sleep, and family functioning may uncover new concerns that warrant investigation.Social & Family Functioning
TS is commonly associated with ADHD, learning problems, and other developmental challenges. TS may first emerge or be identified after 1 of these other entities is discovered. Open-ended questions about academic, social, organizational skills, and family functioning may uncover concerns that warrant investigation.Physical Exam
General
Watch for subtle signs of tics during the history-taking and physical examination. Remember that tics are suppressible and often embarrassing, and individuals will hide their tics in a variety of ways, such as with hair smoothing or stretching. Additionally, tics wax and wane naturally and have a variable frequency so will not necessarily be observed in the clinical settingVital Signs
Check HR | BP if medication is being considered or taken, or for other specific medical indications. Hypotension may occur in children on antipsychotic medications.Growth Parameters
Note baseline and subsequent weights since medications used for TS or co-occurring conditions may be associated with weight change.Skin
Chapping around lips, scabbing associated with repetitive behaviors; “moth-eaten” hair loss due to associated trichotillomaniaHEENT/Oral
Dental trauma (enamel wear, flattening of occlusal surfaces) associated with tooth-chompingTesting
Sensory Testing
Even subtle problems with vision and hearing may compound learning and behavioral difficulties in children with TS, so screening for these sensory impairments should be performed with the initial diagnosis.Genetic Testing
Though TS is genetically influenced, no genetic tests are currently available to help with making the diagnosis.Other Testing
If targeted history and physical exam are suggestive of possible cardiac disease and medications are being considered, cardiovascular workup may be indicated. Children with a family history of sudden death in children or young adults, hypertrophic cardiomyopathy, or long QT syndrome should have a screening EKG [Perrin: 2008]Specialty Collaborations & Other Services
When history and physical examination suggest co-existing conditions outside the scope or competence of the primary care clinician, referral to and coordination with appropriate specialists is indicated. For example, a psychologist or education specialist may evaluate the child's behavior or learning problems, or an occupational therapist might best evaluate fine motor coordination problems. Pediatric specialists with the most expertise in TS and associated conditions may vary by community. Selection among the following specialists may depend on referring provider custom, availability, and/or specialist’s specific expertise.
Tourette Syndrome Programs (see UT providers [1])
Tourette-focused clinical programs, including the 15 Tourette Syndrome Centers of Excellence (Tourette Association) designated by the Tourette Association of America, will offer multi-disciplinary approaches and are likely to have the most ongoing clinical experience in assessing difficult or complex TS.
Mental Health/Counseling > … (see UT providers [1180])
Referral and/or co-management for ADHD, OCD, learning problems, anxiety, sleep problems, depression, anger dysregulation, or autism spectrum disorder may improve functional outcomes.
Educational Testing/Assessment (see UT providers [16])
If problems in school exist, a psycho-educational evaluation that includes IQ
and other cognitive components, academic achievement skills, learning
strengths and weaknesses, attention problems, and social function may help
educational planning. Public schools must complete indicated evaluations at
no cost to the family; private assessment is also available. Testing is
time-consuming and expensive, so it should be performed with specific goals
in mind. Insurance is more likely to cover private testing if results lead
to changes in treatment. See Preauthorization Letter for Psychological Testing (
58 KB).
Developmental - Behavioral Pediatrics (see UT providers [9])
These clinicians bring a "whole-child" perspective, with emphases on neurodevelopmental and psychosocial influences on behavior, learning, and growth. They may have clinical experience with TS and co-existing conditions, including ADHD and learning disabilities.
Psychiatry/Medication Management (see UT providers [63])
Their approach to diagnosis and management of TS may have particular emphasis on the inclusion of psychotropic medication management. Consider referral when such treatment is anticipated or if psychiatry offers the best local expertise with TS.
Neuropsychiatry/Neuropsychology (see UT providers [14])
May assist with neuro-psychological evaluation when TS is complicated by associated disorders and learning problems, and where brain-based impairment in cognitive function/behavior is suspected (e.g., in a child with TS who also has seizures.
Pediatric Neurology (see UT providers [5])
May have considerable clinical experience with TS; particularly helpful if differentiating TS from other movement disorders or seizures
Treatment & Management
Pearls & Alerts for Treatment & Management
Co-existing conditionsThe vast majority of patients with Tourette syndrome and other chronic disorders also have one or more non-tic co-existing conditions, about which concerns usually outweigh those related to problems and interferences associated with tics.
Need for ongoing surveillance/screeningSurveillance and periodic screening for tics and associated co-existing conditions (for example, learning disabilities, anxiety disorders, substance abuse disorders) is an ongoing process, as symptoms emerge over time.
Understand patient/family prioritiesClinicians and families often have different opinions about the importance of tic or related symptoms. Clear and effective communication will help to prioritize problems and guide management.
Systems
Neurology
When tics are mild and not disabling, education about the condition and supportive counseling may suffice. Since tics wax and wane in TS, watchful waiting can be the best approach for some. When tics are disabling due to their impact on social, educational, or other domains, treatment options include comprehensive behavioral intervention for tics and/or pharmacotherapy. Medication remains the treatment of choice for tics of greater severity.
Comprehensive behavioral intervention for tics (CBIT) – not to be confused with cognitive behavioral therapy (CBT) – has been shown to be as effective as pharmacotherapy in reducing tic behaviors in both children and adults. [Pringsheim: 2019] The best candidates are those who recognize their premonitory sensations and are motivated to reduce their tics. CBIT combines Habit Reversal Training and Functional Analysis and can be used alone or with medication. Other behavioral approaches have either not been adequately assessed or have not shown efficacy. Families may be interested in learning more at CBIT: Information for Patients (Tourette Association).
Deep brain stimulation (DBS) is a neurosurgical approach typically reserved for adult patients with severe tics that pose substantial impairment to quality of life or threaten personal safety and who have not responded adequately to comprehensive medication, psychological, and behavioral interventions. In rare cases, DBS may be considered for select pediatric and adolescent patients after thorough investigation with a local ethics committee and/or institutional review board. [Deeb: 2019] [Schrock: 2015]
Transcranial magnetic stimulation (TMS) has also been explored as a treatment option. [Grados: 2018] A decision tree for management of TS can be found at Management Decision Tree (European Society for the Study of TS).

Pharmacy & Medications

in the medical home setting. Each has pros and cons that are described in
[Martino: 2017].Most medications used for tic reduction are prescribed "off-label." The only ones approved by the US Food and Drug Administration for treatment of tics in TS are the typical neuroleptics haloperidol and pimozide and aripiprazole, an atypical neuroleptic. [Silay: 2005] [Sallee: 1997] [Sallee: 2017] Those, however, are generally not used as first-line therapy because of potential adverse side effects, including tardive dyskinesia – a rare but permanent movement disorder that particularly involves the mouth.
Treatment with medications requires a trial and error approach with frequent clinical visits to assess response and titrate dosage. A provider with expertise in tic management is preferable. Medication trials should be conducted over weeks to months to account for waxing and waning tics. In general, start medications at small doses and increase gradually. Any benefits gained with medications should be weighed against current and potential side effects. When medications for tics are to be discontinued, most should be weaned over time, and only under provider guidance.
Alpha-2 adrenergic agonists (clonidine and guanfacine) are often the first choice because their side effects are more tolerable than those of other drug classes and do not include tardive dyskinesia. However, these agents may take weeks or longer to decrease tics, and the reduction is less certain and often less robust than with other agents. Sedation is the most likely side effect of these medications, especially the short-acting forms.
The short-acting forms, which may need to be given 3-4 times a day, can be used initially to assess tolerability and then switched to a long-acting preparation. Oral long-acting forms are available for clonidine and guanfacine; clonidine is available as a transdermal patch. The latter needs to be changed only once a week and produces less sleepiness than the oral form, but local allergic reactions are common. Guanfacine has a longer half-life and is reportedly less sedating than clonidine.
Beneficial side effects of these agents may include the reduction of hyperactive and impulsive behaviors associated with ADHD and reduced latency to sleep onset in patients with difficulty getting to sleep.
Neuroleptics are usually reserved for more severe tics. Although they work well, no medication is successful in all people at doses that don't cause some side effects. Medications should be started at small doses that are increased gradually as needed while watching for side effects. The most common side effects are sedation and weight gain, but neurologic side effects, such as Parkinson-like symptoms and tremor, are also possible. Although dystonic reactions are rare, families should be warned about them. Atypical neuroleptics pose a risk for development of insulin resistance and diabetes – periodic laboratory monitoring is required.
The typical neuroleptics haloperidol and pimozide and the atypical aripiprazole are approved for use by the FDA. [Silay: 2005] [Sallee: 1997] Among atypicals, risperidone and olanzapine have been shown to be effective. [Sandor: 2003] [Budman: 2001] [Bruun: 1996] After long-term use, neuroleptics need to be discontinued slowly to avoid withdrawal problems that may include a rebound in tic frequency and tardive dyskinesia.
Botulinum toxin (Botox) is most helpful when the patient has a severe, localized tic, such as in the face or neck. It is injected by an experienced practitioner into the affected muscle groups. The therapeutic effect lasts for several months.
Anti-epileptic drugs (topiramate in particular) may be useful in reducing tic severity; however, potential side effects are important to consider, particularly at higher doses. [Yang: 2013]
Benzodiazepines, antispasmodic agents (baclofen), dopamine agonists (pergolide), and tetrabenazine are also considered options for treatment of tics. The research on each of these agents is variable; until more thorough research is undertaken, available evidence for the use of these agents is limited.

Mental Health/Behavior
Attention Deficit Hyperactivity Disorder (ADHD) is the most commonly occurring comorbid condition. The presence of tics should not affect a choice among standard treatment modalities – stimulant medications are unlikely to influence tic behavior. Families should know that the course of tics is unpredictable and a waxing of tics while on stimulant medication could falsely suggest they are the cause. [Tourette's: 2002] [Erenberg: 2005] Although the alpha-2 adrenergic agonists clonidine and, less so, guanfacine may be helpful for the treatment of ADHD symptoms in those with TS, these medications are usually not as effective as stimulants and take weeks to months to show beneficial effects. The alpha-2 agonists may, however, help decrease the frequency and intensity of tics in some patients, reduce hyperactive and impulsive behaviors in children with co-occurring ADHD, and, when taken in the evening, assist with reducing sleep onset latency.
Children with obsessive-compulsive disorder (OCD) and tics may not respond as well as those without tics to selective serotonin reuptake inhibitors, but both groups respond similarly to cognitive behavioral therapy (CBT) for OCD symptoms. CBT is the recommended first-line treatment of OCD in individuals with tic disorders. [Pringsheim: 2019]

Ask the Specialist
Why do children with TS sometimes shout obscenities and ethnic slurs?
Coprolalia occurs in fewer than 15% of people with TS. These symptoms appear to be due to an uncontrollable urge to "voice the forbidden," even when the person with TS does not feel anger.
What do tics feel like?
There is often a premonitory sensation that individuals feel prior to a tic behavior. Though this sensation differs across individuals (and even across different tic types), it is often described as a pressure-like sensation or an ‘itch’ in the muscle group where the tic occurs that may build over time. A specific example everyone is familiar with is the sensation that builds up in the eyelids when holding back a blink, and the subsequent relief after blinking is similar to the relief that occurs after performing a tic.
What is the difference between a tic and a motor stereotypy?
Both tics and motor stereotypies are technically “stereotyped,” which is to say that the behavior is performed in a similar way again and again. Motor stereotypies are sustained and repetitive movements that are rhythmic, generally emerge in the toddler years, do not have a premonitory urge, are pleasurable, and typically do not change over time. Tics, in contrast, occur in bouts but are not sustained, are not rhythmic, generally emerge later in childhood, start with a premonitory sensation that drives a tic, are unpleasant (but are followed by relief), and tend to change in type over time.
