Quick Answer: What is Tourette syndrome and how is it treated?
Tourette syndrome is a disorder involving repetitive movements or unwanted sounds, called tics, that cannot be easily controlled. Tics typically start between ages 2 and 15, around age 6 on average, and males are about three to four times more likely to be affected. There is no cure, but treatments exist, and tics often lessen after the teen years.

What the research says
Behavior therapy works for children's tics. In a randomized trial of 126 children aged 9 to 17, 52.5% of those given a comprehensive behavioral intervention for tics were rated much or very much improved after 10 weeks, versus 18.5% of those given supportive therapy and education. Among responders who could be assessed, 87% still showed benefit 6 months later (Piacentini et al., JAMA, 2010).
Medicines can reduce tics, but they differ in strength. A network meta-analysis of 39 randomized trials (4,578 participants, average age about 12) found that antipsychotic drugs reduced tics more than placebo (standardized effect size −0.65 for first-generation and −0.71 for second-generation drugs). Alpha-2 agonists such as clonidine were less powerful (−0.21) but still better than placebo (Farhat et al., The Lancet Child & Adolescent Health, 2023).
Many people improve by adulthood, but not everyone. French national guidelines report that tics usually begin around age 6 or 7, most patients improve by the end of the second decade of life, and symptoms persist into adulthood in around one-third. Coprolalia (involuntary swearing) is present in only about 10% of cases (Hartmann et al., Revue Neurologique, 2024).
What Is Tourette Syndrome?
Tourette syndrome is a disorder that involves repetitive movements or unwanted sounds (tics) that can't be easily controlled. For instance, you might repeatedly blink your eyes, shrug your shoulders or blurt out unusual sounds or offensive words [1].
Tics are the hallmark sign of the condition. They can range from mild to severe, and severe symptoms might significantly interfere with communication, daily functioning, and quality of life [1].
Importantly for parents, tics typically show up between ages 2 and 15, with the average being around 6 years of age. Males are about three to four times more likely than females to develop Tourette syndrome [1].
What Does Tourette Syndrome Feel Like?
Before a motor or vocal tic happens, you'll likely experience an uncomfortable bodily sensation — called a premonitory urge — such as an itch, a tingle, or tension. Expressing the tic brings relief [1].
With great effort, some people with Tourette syndrome can temporarily stop or hold back a tic. But the effort builds, which is why suppression usually can't be sustained [1].
How Are Tics Classified?
Tics are classified in two main ways: how simple or complex they are, and whether they involve movement or sound [1].
Simple tics are sudden, brief, and repetitive, and involve a limited number of muscle groups. Complex tics are distinct, coordinated patterns of movements that involve several muscle groups.
Tics can involve movement (motor tics) or sounds (vocal tics). Motor tics usually begin before vocal tics do, but the spectrum of tics that people experience is diverse [1].
Type | Examples |
Simple motor tics | Eye blinking, head jerking, shoulder shrugging, eye darting, nose twitching, mouth movements |
Complex motor tics | Touching or smelling objects, repeating observed movements, stepping in a certain pattern, obscene gesturing, bending or twisting, hopping |
Simple vocal tics | Grunting, coughing, throat clearing, barking |
Complex vocal tics | Repeating one's own words or phrases, repeating others' words or phrases, using vulgar, obscene, or swear words |
Why Do Tics Come and Go?
Tourette syndrome tics come and go because they naturally vary in type, frequency and severity and can worsen with illness, stress, anxiety, tiredness or excitement. Based on the source material, tics can do all of the following [1]:
Vary in type, frequency, and severity over time
Worsen if you're ill, stressed, anxious, tired, or excited
Occur during sleep
Change over time
Worsen in the early teenage years and improve during the transition into adulthood
That last point matters for long-term outlook. Tics often lessen or become controlled after the teen years, and many people with Tourette syndrome don't need treatment when symptoms aren't troublesome [1].
What Causes Tourette Syndrome?
The exact cause of Tourette syndrome isn't known. It's a complex disorder likely caused by a combination of inherited (genetic) and environmental factors [1].
Chemicals in the brain that transmit nerve impulses — called neurotransmitters — including dopamine and serotonin, might play a role in the condition [1].
What Are the Risk Factors?
Two risk factors are identified in the source material [1]:
Risk factor | What the evidence says |
Family history | Having a family history of Tourette syndrome or other tic disorders might increase the risk of developing Tourette syndrome |
Sex | Males are about three to four times more likely than females to develop Tourette syndrome |
What Conditions Are Linked to Tourette Syndrome?
People with Tourette syndrome often lead healthy, active lives. However, the condition frequently involves behavioral and social challenges that can harm self-image [1].
Several other conditions are often associated with Tourette syndrome. This matters for treatment, because therapy frequently targets these accompanying problems rather than the tics themselves [1]:
Associated condition | Why it matters |
ADHD | Affects attention and concentration; can be treated with specific medications |
Obsessive-compulsive disorder (OCD) | Involves obsessions; treatable alongside tics |
Autism spectrum disorder | Can complicate social functioning |
Learning disabilities | Affects school support needs |
Sleep disorders | Tics can occur during sleep; associated condition |
Depression | Self-esteem challenges raise the risk |
Anxiety disorders | Affects coping and social engagement |
Pain related to tics | Especially headaches |
Anger-management problems | Affects behavior and impulse control |
The sources note an important social dimension: self-esteem may suffer as a result of Tourette syndrome. You may be embarrassed about your tics and hesitate to engage in social activities, such as dating or going out in public. As a result, there's an increased risk of depression and substance abuse [2].

When Should You See a Doctor?
If you notice your child displaying involuntary movements or sounds, see your child's pediatrician [1].
Not all tics indicate Tourette syndrome. Many children develop tics that go away on their own after a few weeks or months. But whenever a child shows unusual behavior, it's important to identify the cause and rule out serious health problems [1].
How Is Tourette Syndrome Diagnosed?
There's no specific test that can diagnose Tourette syndrome. The diagnosis is based on the history of your signs and symptoms [2].
The diagnosis rests on four main criteria, and tics also usually change over time [2]:
# | Diagnostic criterion |
1 | Both motor tics and vocal tics are present, although not necessarily at the same time |
2 | Tics occur several times a day, nearly every day or intermittently, for more than a year |
3 | Tics begin before age 18 |
4 | Tics aren't caused by medications, other substances, or another medical condition |
5 | Tics often change over time in location, frequency, type, complexity, or severity (common, but not a formal DSM-5 requirement) |
Why diagnosis can be missed: A diagnosis might be overlooked because the signs can mimic other conditions. Eye blinking might be initially associated with vision problems, or sniffling attributed to allergies [2].
Both motor and vocal tics can be caused by conditions other than Tourette syndrome. To rule out other causes of tics, your doctor might recommend blood tests and imaging studies such as an MRI [2].
How Is Tourette Syndrome Treated?
There's no cure for Tourette syndrome. Treatment is aimed at controlling tics that interfere with everyday activities and functioning. When tics aren't severe, treatment might not be necessary [2].
Which Medications Are Used?
Medications to help control tics or reduce symptoms of related conditions include the following, based on the source material [2]:
Medication type | Examples | What it helps with | What to watch for |
Dopamine blockers/lesseners | Fluphenazine, haloperidol, risperidone, pimozide | Can help control tics | Possible side effects include weight gain and involuntary repetitive movements |
Tetrabenazine | — | Might be recommended to control tics | May cause severe depression |
Botulinum (Botox) injections | — | An injection into the affected muscle might help relieve a simple or vocal tic | — |
ADHD medications | Methylphenidate, dextroamphetamine-containing medications | Can help increase attention and concentration | For some people with Tourette syndrome, ADHD medications can exacerbate tics |
Central adrenergic inhibitors | Clonidine, guanfacine | Might help control behavioral symptoms such as impulse control problems and rage attacks | Side effects may include sleepiness |
Antidepressants | Fluoxetine | Might help control symptoms of sadness, anxiety, and OCD | — |
Antiseizure medications | Topiramate | Recent studies suggest some people with Tourette syndrome respond | — |
Read more about one of these options in our guide to Pimozide: Managing Vocal and Motor Tics in Tourette Disorder.
Which Therapies Are Used?
Three therapy approaches are described in the source material [2]:
Behavior therapy. Cognitive Behavioral Interventions for Tics, including habit-reversal training, can help you monitor tics, identify premonitory urges, and learn to voluntarily move in a way that's incompatible with the tic.
Psychotherapy. In addition to helping you cope with Tourette syndrome, psychotherapy can help with accompanying problems, such as ADHD, obsessions, depression, or anxiety.
Deep brain stimulation (DBS). For severe tics that don't respond to other treatment, DBS might help. It involves implanting a battery-operated medical device in the brain to deliver electrical stimulation to targeted areas that control movement. However, this treatment is still in the early research stages and needs more research to determine if it's a safe and effective treatment for Tourette syndrome.
How Can People With Tourette Syndrome Cope?
Self-esteem may suffer as a result of Tourette syndrome. You may be embarrassed about your tics and hesitate to engage in social activities, such as dating or going out in public. As a result, you're at increased risk of depression and substance abuse [2].
The sources suggest two coping approaches [2]:
Remember the trajectory. Tics usually reach their peak in the early teens and improve as you get older.
Reach out to others. Connect with others dealing with Tourette syndrome for information, coping tips, and support.

How Can Parents Help a Child With Tourette Syndrome at School?
Parents can help a child with Tourette syndrome at school by advocating for the child, nurturing the child's self-esteem and finding a support group. The sources offer three practical steps for parents [2]:
Be your child's advocate. Help educate teachers, school bus drivers, and others with whom your child interacts regularly. An educational setting that meets your child's needs — such as tutoring, untimed testing to reduce stress, and smaller classes — can help.
Nurture your child's self-esteem. Support your child's personal interests and friendships — both can help build self-esteem.
Find a support group. Seek out a local Tourette syndrome support group. If there aren't any, consider starting one.
How Should You Prepare for a Tourette Syndrome Appointment?
If you or your child has been diagnosed with Tourette syndrome, you may be referred to specialists, such as doctors who specialize in brain disorders (neurologists) and psychiatrists or psychologists [2].
Here's how the sources suggest preparing [2]:
Preparation step | What to do |
Pre-appointment restrictions | At the time you make the appointment, ask if there's anything you need to do in advance, such as restrict your diet |
Symptom list | Write down any symptoms you or your child is experiencing, including any that may seem unrelated |
Key personal information | Write down any major stresses or recent life changes |
Medication list | Make a list of all medications, vitamins, or supplements you or your child is taking |
Tic recording | Make a video recording, if possible, of a typical tic to show the doctor |
Questions | Write down questions to ask your doctor, listed from most important to least important |
Questions worth asking the doctor [2]:
What treatment, if any, is needed?
If medication is recommended, what are the options?
What types of behavior therapy might help?
Questions your doctor may ask [2]:
When did the symptoms begin?
Have the symptoms been continuous or occasional?
How severe are the symptoms?
What, if anything, seems to improve the symptoms?
What, if anything, appears to worsen the symptoms?
What is the bottom line on Tourette syndrome?
Tourette syndrome is a tic disorder that typically begins in childhood, affects males more often than females, and has no cure — but it's far from a life sentence. Tics often peak in the early teens and improve afterward, many people need no treatment when symptoms are mild, and medication, behavior therapy, and psychotherapy can help when tics interfere with daily life. The single most important action step: if you notice involuntary movements or sounds in your child, see your child's pediatrician to identify the cause and rule out serious health problems.
Take the next step. Talk to your pediatrician or a neurologist about any tics you've noticed. Bring a video recording of a typical tic to the appointment, write down your questions in advance, and remember that most people with Tourette syndrome lead healthy, active lives.

Tics can worsen if you're ill, stressed, anxious, tired, or excited. They can also vary in type, frequency, and severity, and occur during sleep.
10. How is Tourette syndrome diagnosed? Is there a test?
There's no specific test. Diagnosis is based on the history of signs and symptoms against four criteria: both motor and vocal tics, lasting more than a year, starting before age 18, and not caused by medications or another condition. Tics also usually change over time. Blood tests or an MRI may be used to rule out other causes.
11. Why does Tourette syndrome diagnosis often get missed?
The signs can mimic other conditions — eye blinking might be initially associated with vision problems, or sniffling attributed to allergies.
12. Do you need treatment for Tourette syndrome?
Not always. Treatment is aimed at controlling tics that interfere with everyday activities and functioning. When tics aren't severe, treatment might not be necessary.
13. What medications treat Tourette syndrome?
Options include medications that block or lessen dopamine (fluphenazine, haloperidol, risperidone, pimozide, tetrabenazine), botulinum (Botox) injections, ADHD medications, central adrenergic inhibitors (clonidine, guanfacine), antidepressants (fluoxetine), and antiseizure medications (topiramate).
14. Can ADHD medication make tics worse?
For some people with Tourette syndrome, medications for ADHD can exacerbate tics — which is why treatment should be coordinated with your doctor.
15. What is habit-reversal training?
It's part of Cognitive Behavioral Interventions for Tics. It helps you monitor tics, identify premonitory urges, and learn to voluntarily move in a way that's incompatible with the tic.

18. Can Tourette syndrome run in families?
Yes — having a family history of Tourette syndrome or other tic disorders might increase the risk of developing it.
19. What other conditions are associated with Tourette syndrome?
ADHD, OCD, autism spectrum disorder, learning disabilities, sleep disorders, depression, anxiety disorders, pain related to tics (especially headaches), and anger-management problems.
20. Does Tourette syndrome affect self-esteem?
It can. You may be embarrassed about your tics and hesitate to engage in social activities, such as dating or going out in public, which raises the risk of depression and substance abuse. Coping strategies include remembering that tics improve with age and reaching out to support groups.
21. How can parents help a child with Tourette syndrome at school?
Be your child's advocate (educate teachers and staff; consider tutoring, untimed testing, and smaller classes), nurture your child's self-esteem by supporting personal interests and friendships, and find or start a local support group.
22. What should I bring to a Tourette syndrome appointment?
A symptom list, key personal information (stresses, life changes), a medication list, a video recording of a typical tic if possible, and a prioritized list of questions for the doctor.
23. Should I be worried if my child has tics?
Not necessarily — many children develop tics that go away on their own after a few weeks or months. But whenever a child shows unusual behavior, it's important to identify the cause and rule out serious health problems, so see your child's pediatrician.
