Tourette Syndrome

Overview

Tourette syndrome is a condition of the nervous system that causes people to make sudden, repeated movements or sounds called tics. These tics are not intentional and can be hard to control. They may change over time and can vary from mild to severe.

Yes. Tourette syndrome affects about 1 in 100 people. Many cases are mild and some people may not even know they have it.

Tourette syndrome can affect anyone, but it is about 3 to 4 times more common in boys than in girls. It usually starts before age 18, and symptoms often show up between ages 5 and 10.

Symptoms

Common symptoms

• Motor tics: sudden, quick movements like blinking, shoulder shrugging, head jerking, or facial grimacing.
• Vocal tics: sounds such as throat clearing, grunting, sniffing, or repeating words or phrases.
• Simple tics: short, repetitive movements or sounds that involve a few muscles.
• Complex tics: coordinated patterns of movement, like touching, jumping, or repeating movements in a sequence.
• A feeling or urge just before the tic, often described as a build-up of tension that the tic briefly releases.
• Tics that may be suppressed for a short time but often need to come out eventually.
• Tics that get worse with stress, excitement, or fatigue and may ease during calm, focused activities.

Symptoms in children

• Tics often start around age 5 to 7 and may become more noticeable between ages 8 and 12.
• Children may also have trouble paying attention, be restless, or have repetitive thoughts.
• Some children feel embarrassed or frustrated, especially if peers tease them.
• Sleep problems, such as difficulty falling asleep or waking at night, are more common in children with Tourette.

Symptoms in older adults

• Tics often become milder in later life, but some adults continue to have tics.
• Adults may have learned to suppress tics in public, but tics can still happen when they relax.
• Older adults may experience tics alongside other health conditions or as a result of stress, fatigue, or certain medicines—but this is different from Tourette syndrome and should be checked by a doctor.

Causes

Main causes

• The exact cause is not fully understood, but it involves differences in the brain circuits that control movement and habit formation.
• Genetics play a role—Tourette syndrome often runs in families.
• It is not caused by bad parenting, emotional weakness, or anything the person did.
• Changes in brain chemicals, such as dopamine, may also be involved.

Risk factors

• A family history of Tourette syndrome or other tic disorders.
• Being male.
• Having another neurodevelopmental condition such as ADHD, OCD, or anxiety.
• Stress, lack of sleep, or excitement can make existing tics worse, though they do not cause Tourette.

When to see a doctor

See a doctor urgently if:

• If you or your child has tics that cause injury or self-harm, or if there are thoughts of self-harm, call emergency services immediately.
• If tics stop you from breathing, eating, or drinking, seek urgent care same day.

Book a routine appointment if:

• Make an appointment with a doctor if tics are frequent, embarrassing, or interfering with school, work, or social life.
• If you notice tics in your child that last for more than a year, mention it to a healthcare provider.
• If you have concerns about associated symptoms like anxiety, depression, or trouble concentrating, talk to your doctor.

Diagnosis

Doctors diagnose Tourette syndrome by listening to the history of the tics and watching or describing them. There is no single test. The main requirements are having at least two motor tics and one vocal tic, starting before age 18, and lasting for more than a year.

Tests that may be done

• Most people do not need any tests.
• If a doctor suspects another condition, they may recommend blood tests or brain imaging, but this is not common for Tourette syndrome.

What to expect at your appointment

Your doctor will ask detailed questions about the tics, when they started, how often they happen, and whether anything makes them better or worse. They may also ask about family history and any other symptoms. A specialist, such as a neurologist or a child and adolescent psychiatrist, may be involved to confirm the diagnosis and offer support.

Treatment

Treatment is not always needed. If tics are mild and not causing problems, education and reassurance are often enough. If tics affect daily life, there are effective non-drug treatments and, in some cases, medication—but the decision is made together with a specialist.

Self-care at home

• Learn to notice early signs of a tic and practise briefly delaying or redirecting it in a safe, less noticeable way.
• Reduce stress with relaxation techniques, deep breathing, or mindfulness.
• Get enough sleep and keep a steady daily routine.
• Keep a tic diary to spot triggers such as anxiety, excitement, or certain activities.
• Take short breaks at school or work when tics feel more intense.

Medical treatments

The first-line treatment for tics is behaviour therapy, such as habit reversal or exposure and response prevention. A trained therapist teaches you to recognise the urge and perform a different, less obvious movement instead. If tics are severe and therapy alone is not enough, a specialist may consider medication that affects brain chemicals to reduce tics. These medicines are not suitable for everyone and are only used when the benefits clearly outweigh side effects. They are always started at low doses and closely monitored by a doctor.

When is surgery considered?

Surgery is not a standard treatment for Tourette syndrome. It is only considered in extremely rare and severe cases that do not respond to any other treatment, and always after thorough evaluation by a specialist team.

Living with this condition

Tics often come and go in waves. You may be able to hold in a tic for a while, but eventually it needs to come out. It helps to remind yourself that tics are involuntary—not a sign of weakness. You can let teachers, colleagues, and friends know that tics are a medical condition and not something you can fully control. Give yourself permission to step away when you need to decompress.

Lifestyle tips

• Regular physical activity can help burn off nervous energy and improve mood.
• Aim for consistent, restful sleep—tiredness can make tics worse.
• Keep a daily structure so you do not feel rushed or overwhelmed.
• Limit caffeine and energy drinks, as they can increase anxiety and tics.
• Make time for hobbies and relaxing activities you enjoy.

Diet and exercise

No special diet is proven to treat Tourette syndrome, but a balanced diet and regular exercise support overall health and wellbeing. Some people notice their tics change when they eat certain foods or skip meals, so it can help to keep a food and tic diary.

Mental health and emotional wellbeing

Growing up with Tourette can be stressful. Teasing, embarrassment, and constant effort to hide tics can lead to anxiety, low mood, or poor self-esteem. Many people with Tourette also have obsessive-compulsive disorder (OCD) or attention-deficit/hyperactivity disorder (ADHD). It is very important to talk about these feelings—with family, friends, a counsellor, or a healthcare provider—and to seek help if you or your child feel overwhelmed.

Prevention

Tourette syndrome is not currently preventable because it is likely genetic. No vaccine, medicine, or lifestyle change can stop it from developing. However, early recognition and support can help reduce the emotional and social impact of tics.

Complications

If left untreated

• Tics may continue into adulthood if no treatment or support is given.
• Social difficulties, such as being teased or excluded, can lead to low self-esteem.
• Anxiety, depression, or obsessive-compulsive symptoms may develop or worsen.
• School or work performance can suffer if tics interfere with concentration or cause absence.

Long-term outlook

Most people with Tourette syndrome live full and successful lives. Tics often become milder after the teenage years, and many adults find they have long periods with few or no symptoms. With understanding, coping skills, and the right support, it is very possible to thrive.
