What is Tourette’s syndrome?

Tourette’s syndrome is a neurodevelopmental condition where a person has both motor tics (movements) and vocal or phonic tics (sounds) that persist over time.¹–³ Tics are sudden, repeated movements or sounds that are not fully voluntary, even when a person can sometimes hold them back briefly.¹–³

A practical way to think about Tourette’s is this: Imagine your nervous system has a “tic channel” that can turn up or down depending on the day, stress level, sleep, and attention demands. Tics are real symptoms with recognizable patterns described in clinical guidelines, not a character flaw, not poor parenting, and not “just anxiety,” even though anxiety can make symptoms louder.¹–⁴

​

​

What are tics, and what is the difference between motor tics and vocal tics?

Tics are sudden, rapid, recurrent, non-rhythmic movements or vocalizations.³ They often happen in clusters, and they commonly change in frequency, intensity, and type over time.¹–³

Motor tics involve movement, like blinking, facial grimacing, head jerks, shoulder shrugs, or brief body movements.¹–³ Vocal or phonic tics involve sounds, like sniffing, throat clearing, humming, squeaking, or short words.¹–³ Some tics are simple, quick, and brief, while others are complex and longer, involving sequences of movements or sounds.³

Can people with Tourette’s control their tics?

Many people can suppress tics for short periods, especially in situations where they feel watched or where a tic would be embarrassing.³,⁵ But suppression often takes energy and attention, and it can lead to a rebound, meaning more tics later when the person relaxes or is finally in a safe space.³,⁵

This matters for everyday life. If a child “keeps it together” at school and then seems to explode with tics at home, that pattern can fit what clinicians see in tic disorders, and it does not mean they were faking earlier.³,⁵ It can mean they were working very hard to hold back symptoms, then the dam finally let the water through.³,⁵

What does “waxing and waning” mean, and why do tics change over time?

“Waxing and waning” means tic severity naturally rises and falls. Symptoms can be quieter for weeks, then flare, then soften again, even without a single clear trigger.¹–³

Guidelines describe this variability as part of the condition itself.³ Some people also notice that tic types change over time, with new tics appearing and older ones fading.¹–³ Tracking patterns over weeks, not hours, often gives a truer picture of what is happening, like watching the tide rather than a single splash.¹–³

What is a premonitory urge, and why does it matter?

A premonitory urge is a build-up sensation that often comes right before a tic, like pressure, tension, itchiness, tingling, or a feeling that something is “not right” until the tic happens.⁶,⁷ For many people, the tic briefly relieves that sensation, which can reinforce the urge-tic cycle.⁶,⁷

Premonitory urges matter because many evidence-based behavioral treatments, especially CBIT, teach skills that work with this cycle.⁵,⁸ When someone learns to notice the urge earlier, it can create a small gap, a thin seam of light, where a different response can be practiced.⁵,⁸

When do Tourette’s symptoms usually start, and how do they change with age?

Tourette’s symptoms usually begin in childhood, commonly around ages 5 to 10.¹,⁹ Early tics often start in the head and neck area, like blinking or facial movements.¹,⁹

Many people experience improvement in tic severity during adolescence or early adulthood, although not everyone does, and the course can differ person to person.⁴,⁵,⁹ Clinical guidance encourages clinicians to discuss the natural history of tic disorders because it can support realistic hope and better pacing of treatment decisions.⁴,⁵

Is coprolalia common in Tourette’s?

Coprolalia is the involuntary saying of obscene or socially inappropriate words. It is one of the most talked-about symptoms in pop culture, but it is not typical for most people with Tourette’s.¹⁰,¹¹

Public health resources note that coprolalia affects about 1 in 10 people with Tourette’s, and it is not required for diagnosis.¹⁰ This is important because media stereotypes can feel like a mask forced onto someone’s face, and it can pull attention away from the more common challenges, like discomfort from urges, attention difficulties, anxiety, and social strain.¹⁰,¹¹

How is Tourette’s diagnosed, and what does a good evaluation include?

Tourette’s is diagnosed clinically, based on symptom history and pattern, not by a single blood test or brain scan.²,³,¹² A strong evaluation usually includes: when tics started, what tics look like, how long they have persisted, what makes them better or worse, and how much they affect daily function.²,³,¹²

Guidelines also emphasize screening for co-occurring conditions and using structured measures when helpful, such as the Yale Global Tic Severity Scale (YGTSS) for tic severity.³ If symptoms are atypical, sudden in onset, or accompanied by other concerning neurologic changes, clinicians may consider additional testing to rule out other causes, based on the full clinical picture.²,³,¹²

How do clinicians tell tics apart from other movements or sounds?

This is a common worry, especially when symptoms are new or intense. Tourette’s tics typically have a recognizable pattern: childhood onset, waxing and waning course, and often a premonitory urge.³,⁶

Clinicians may also consider other possibilities, like stereotypies, compulsions, seizures, medication side effects, or functional tic-like behaviors, depending on the presentation.³ If the diagnosis feels unclear, it is reasonable to ask, “What features point toward a tic disorder here, what features point away, and what would change the plan if this is something else?”³

What conditions commonly occur alongside Tourette’s, and why does that matter for treatment?

Tourette’s often occurs with ADHD, obsessive-compulsive symptoms or OCD, anxiety, learning difficulties, and mood symptoms.⁴,¹³,¹⁴ For many people, these co-occurring conditions cause more day-to-day impairment than the tics themselves, especially at school, work, or in relationships.⁴,¹³,¹⁴

Guidelines emphasize treating the whole person, not just the tics.⁴,¹³ For example, addressing ADHD can improve focus and functioning even if tics remain, and treating anxiety can reduce stress-driven tic flares.⁴,¹³,¹⁴ If you are building a care plan, it helps to name which problem is the loudest right now, and which change would most improve daily life.⁴,¹³

When is treatment recommended, and when is watchful waiting reasonable?

Treatment is usually guided by functional impairment, meaning how much symptoms interfere with safety, comfort, learning, work, social life, and emotional well-being.⁴,¹³ If tics are mild and not causing meaningful problems, watchful waiting with education and periodic reassessment can be appropriate.⁴,¹³

When treatment is needed, guidelines support a stepwise approach. That often starts with education, then evidence-based behavioral therapy when accessible, and then medication options when symptoms are causing ongoing impairment or when behavioral therapy is not enough or not available.⁴,¹³ The goal is not perfection, it is relief and function, more steady days, fewer storms.⁴,¹³

What is CBIT, and why is it often a first-line treatment?

Comprehensive Behavioral Intervention for Tics (CBIT) is an evidence-based therapy that helps people understand their tic patterns and practice specific skills to reduce tic severity and tic-related impairment.⁵,⁸,¹⁵ Major guidelines recommend CBIT as an initial treatment option for many people who need active treatment for tics.⁴,¹³

CBIT is structured skill-building, like physical therapy for a symptom pathway. It is also personalized: it targets the tics that matter most, in the situations where they cause the most trouble.⁵,⁸,¹⁵

What skills are taught in CBIT, and what does treatment usually look like?

CBIT usually includes awareness training (noticing early signals and patterns), competing response training (practicing a movement that makes the tic harder to complete), and functional interventions (changing triggers and routines that keep tics firing).⁵,⁸

Evidence from large randomized clinical trials in children and adults showed CBIT outperformed supportive or psychoeducation-based control treatments for tic reduction and impairment.¹⁵,¹⁶ Public health resources describe CBIT as systematic and planned to match the person’s specific tics and daily situations, commonly delivered over a set of sessions with practice between visits.⁵,¹⁷

 

If you are considering CBIT, you can ask: 

 

“How will we measure progress, what is the home practice plan, and what happens if a new tic replaces an older one?”³,⁵,⁸

What medications are used for tics, and how do clinicians choose among them?

Medication may be considered when tics cause significant impairment, when CBIT is not available, or when CBIT alone is not enough.⁴,¹³ Medication choice is typically shaped by tic severity, age, side effect risks, and co-occurring conditions like ADHD, anxiety, or OCD.⁴,¹³,¹⁴

European and American guidance describes several medication categories used in practice, including alpha-2 adrenergic agonists (often considered when ADHD co-occurs) and antipsychotic medications for more severe or persistent tics, among other options.⁴,¹³,¹⁴ The key is shared decision-making with careful monitoring, because symptom relief and side effects both matter.⁴,¹³,¹⁴

What should people watch for with tic medications, and how is safety monitored?

Many tic medications can help, but they can also carry meaningful side effects, depending on the medication. Guidelines highlight risks such as sedation, weight gain, metabolic effects, movement-related side effects, and cardiovascular effects like changes in blood pressure or heart rate, again depending on the drug.¹⁴

Because side effects can creep in quietly, monitoring is part of good care, not an afterthought. If medication is being considered, it is reasonable to ask: “What symptom change are we aiming for, what side effects should we track, what labs or vital signs are needed, and when do we reassess to adjust or stop?”⁴,¹³,¹⁴ If a medication is stopped, guidance commonly recommends tapering certain drugs rather than stopping abruptly, to reduce withdrawal or rebound problems.¹⁴

Are there targeted treatments for a single severe tic, like a painful neck jerk or eye squeezing?

When one focal tic causes outsized harm, like pain, injury risk, or functional disruption, botulinum toxin injections may be discussed for selected patients.⁴,¹³ The goal is not to treat Tourette’s as a whole, but to reduce the impact of a specific tic that is doing most of the damage.⁴,¹³

This is a very individualized decision. It can help to ask: “Is this tic focal enough to target, what benefits are realistic, and what temporary weakness or voice changes might happen based on where it is injected?”⁴,¹³

What supports help at school or work, and how do they reduce day-to-day burden?

Supportive environments can reduce impairment even when tics continue. Public health and guideline resources emphasize psychoeducation for teachers and peers because understanding often reduces stigma and improves daily functioning.⁴,¹³,¹⁸

When accommodations are needed, they are often practical and low-drama, aimed at reducing unnecessary friction. Examples discussed in educational resources include flexible testing time, alternative presentation formats, seating changes, keyboard use if writing is difficult, brief breaks, or a plan for leaving class momentarily during intense tic bouts.¹⁹,²⁰

 

If this is relevant, you can ask a clinician or school support team:

 

“What accommodations match the actual barriers we are seeing, and how will we measure whether they are helping?”¹⁹,²⁰

What is deep brain stimulation (DBS), and is it a standard treatment for Tourette’s?

Deep brain stimulation (DBS) is a surgical therapy that places thin electrodes in targeted brain circuits and connects them to an implanted pulse generator, which delivers programmed stimulation.²¹ Tourette’s is not one of the routine, standard indications for DBS in the way it is for some movement disorders, and DBS for Tourette’s is generally considered only in carefully selected, severe, otherwise treatment-refractory cases, in experienced centers.¹⁴,²²

In other words, DBS is not an early step. It is usually discussed when tics remain profoundly disabling despite appropriate trials of evidence-based behavioral therapy and medications, with careful evaluation of co-occurring psychiatric symptoms and overall stability.¹⁴,²²

What does “treatment-refractory” usually mean when DBS is considered for Tourette’s?

“Treatment-refractory” generally means more than, “We tried a couple of things and it didn’t work.” Guidelines describe broad agreement that multiple appropriate treatments should have been used in adequate dose, frequency, and duration before someone is considered treatment-refractory.²²

This is where documentation becomes helpful, not as paperwork, but as clarity. A careful history of what was tried, what helped, what caused side effects, and what goals remain unmet helps specialist teams decide whether DBS evaluation makes sense and what the realistic targets of treatment should be.¹⁴,²²

What does research say about DBS outcomes for Tourette’s, and what remains uncertain?

Systematic reviews and meta-analyses generally report meaningful average improvements in tic severity after DBS in selected patients, but results vary across individuals and across stimulation targets.²³,²⁴ The evidence base includes differences in study design, patient selection, targets, and outcome reporting, so guidelines emphasize cautious interpretation and the need for expert teams and long-term follow-up.¹⁴,²²

A grounded way to hold hope and uncertainty together is to ask specific questions: “Which target does this center use most often, what evidence supports that choice, what risks are most relevant for me, and what is the expected timeline for programming and follow-up?”¹⁴,²²,²³ DBS is a therapy that evolves over time after surgery, and the programming phase can be a process, sometimes slow and iterative.²¹,²²

Are noninvasive brain stimulation options, like rTMS, used for Tourette’s?

Repetitive transcranial magnetic stimulation (rTMS) has been studied for tic disorders, but evidence is less established than CBIT and standard medication approaches, and results across trials have been mixed.²⁵

A recent meta-analysis found no statistically significant overall reduction in tic severity with TMS across included trials, though it reported a moderate reduction in premonitory urge severity.²⁵ If rTMS is offered, it is reasonable to ask whether it is part of research or standard clinical care, what protocol is used, and how outcomes will be measured against guideline-supported options.²⁵
