It often starts with something small: a child blinking hard for weeks, clearing their throat long after the cold has gone, or jerking their head in a way that looks like a habit. For most children these tics come and go and mean nothing. For a smaller group they’re the first sign of Tourette syndrome, a childhood brain condition that sounds frightening but is usually far more manageable than parents fear. Here’s what it is, how it’s diagnosed in Singapore, and what works.
Tourette syndrome is a neurodevelopmental condition where a child has both movement tics and at least one sound tic for more than a year. It usually starts between ages 4 and 6, is about three to four times more common in boys than girls, and affects roughly 1 in 100 children once related tic disorders are counted. The tics tend to peak around 10 to 12, ease through the teens, and most children outgrow the worst of them by adulthood. It isn’t caused by parenting, and most children need reassurance and school support, not medication.
See a doctor if the tics persist for months, worry your child, or affect school and friendships. In Singapore the path runs from your GP or polyclinic to a paediatrician, and on to paediatric neurology at KKH or NUH if needed.

What Tourette syndrome is
Tourette syndrome (TS) is a condition of the developing brain that causes tics: sudden, repeated movements or sounds a child can’t easily control. Doctors diagnose it when a child has had several movement (motor) tics and at least one sound (vocal) tic, on and off for more than a year, starting before age 18. It’s more common than many people think, and the great majority of children with it grow up to live ordinary lives.
Tics aren’t a sign of low intelligence or bad behaviour, and they aren’t something a child is doing on purpose. A child can hold a tic back for a short while, the way you can hold back a sneeze, but the urge builds until it has to come out, often more strongly afterwards.
The tics: what they look like
Tics fall into two groups, and most children with Tourette’s have both over time:
- Motor tics are movements: blinking, grimacing, shrugging, head jerks, or more involved actions like touching or jumping.
- Vocal tics are sounds: sniffing, throat-clearing, grunting, coughing, or repeating words.
They can be simple (a single blink or sniff) or complex (a sequence of movements, or a phrase). The swearing tic that films love to show, called coprolalia, is real but uncommon, affecting only a small minority. Tics wax and wane: they get worse when a child is tired, excited or stressed, and often settle when they’re calm or absorbed in something. Many children feel a build-up of tension first, a premonitory urge, and the tic brings relief.
When it starts, and who it affects
Tics usually appear between the ages of 4 and 6. Tourette’s is about three to four times more common in boys than in girls, and it’s more widespread than many parents realise: roughly 1 in 100 school-age children are affected once Tourette’s and related chronic tic disorders are counted together, with Tourette syndrome on its own a little less common, around 1 in 160.
The pattern from there is reassuring. Severity tends to peak around 10 to 12, then eases: by the late teens many young people have far milder tics, and some have none at all. Most children outgrow the worst of their tics by adulthood, and while a minority carry some into their adult years, they’re usually milder than they were in childhood. Knowing this helps, because the hardest stretch is often not the whole story.
What causes it, and what doesn’t
Tourette’s runs in families, so genes play a large part, alongside differences in how certain brain circuits and the chemical messenger dopamine work. What matters as much is what does not cause it. Tics aren’t the result of strict or lax parenting, too much sugar, or screen time, and scolding a child for a tic only adds stress, which makes tics worse.
One recent wrinkle is worth flagging. Doctors have seen a rise in teenagers, mostly girls, with sudden, dramatic tic-like movements that don’t follow the usual Tourette’s pattern, linked to watching tic videos online. These functional tics are a separate issue and are handled differently, so it helps to know how sudden tics in teenagers relate to social media before assuming any new tic is Tourette’s.
What often comes with it
For many children the tics aren’t the hardest part. Tourette’s frequently comes alongside attention difficulties (ADHD), obsessive-compulsive traits (OCD), anxiety, or learning challenges, and these often affect daily life more than the tics themselves. A good assessment looks for these too, because treating them can make the biggest difference to how a child copes at school and at home.
How it’s diagnosed in Singapore
There’s no blood test or scan for Tourette’s. A doctor diagnoses it from the history and by watching the tics, sometimes using a video you record at home, since tics often hide in the clinic. The usual route in Singapore starts with your GP or polyclinic, who can refer your child to a paediatrician, and on to a paediatric neurologist or child development specialist at KK Women’s and Children’s Hospital or the National University Hospital if the picture is unclear or the tics are troublesome. If you’re weighing up specialists, it helps to see the paediatric neurologists practising in Singapore first.
Treatment and what helps
Most children don’t need medication. The first and most important step is understanding: once a child, their family and their teachers know what tics are and that they aren’t deliberate, a lot of the distress lifts. From there, the main options are:
- Behavioural therapy. A structured approach called CBIT (Comprehensive Behavioural Intervention for Tics), which teaches a child to notice the urge and use a competing movement, has good evidence and no side effects.
- Medication, reserved for tics that hurt, exhaust or seriously disrupt life. Several medicines can reduce tics, and the doctor weighs the benefit against side effects.
- Treating what comes with it. Managing ADHD, OCD or anxiety often improves a child’s day far more than chasing the tics.
Helping your child at home and school
- Don’t punish tics. Telling a child to stop makes the urge stronger and adds shame. Treat a tic the way you’d treat a hiccup.
- Lower the pressure. Tics rise with stress and tiredness, so steady routines, enough sleep and calm help.
- Tell the school. A short conversation with the form teacher, and the school’s Allied Educator where there’s learning support, means a child isn’t told off for tics and can step out if a tic storm hits during an exam.
- Protect their confidence. Let your child explain their tics to close friends in their own words. Children who feel understood cope far better than those who feel they must hide.
When to see a doctor
Most tics in young children fade on their own within months and need no visit. Book an appointment if the tics have lasted several months, involve both movements and sounds, hurt your child, or get in the way of school, sleep or friendships. Get help sooner if a tic is causing injury, or if your child seems low, very anxious or is being bullied over it.
Common questions
Is Tourette syndrome in children serious?
For most children it’s mild and improves through the teens. It needs proper assessment, especially for coexisting ADHD, OCD or anxiety, but the outlook is generally good and most children live ordinary lives.
What age does Tourette syndrome usually start?
Tics usually begin between ages 4 and 6 and must start before age 18 for a diagnosis. Severity often peaks around 10 to 12, then eases.
How common is Tourette syndrome, and does it affect boys more?
Roughly 1 in 100 children are affected once related chronic tic disorders are counted, with Tourette syndrome on its own around 1 in 160. It’s about three to four times more common in boys than in girls.
Can my child control their tics?
Only briefly. A child can hold a tic back for a short time, but the urge builds until it’s released, often more strongly. Tics aren’t done on purpose, so punishing them doesn’t help.
Where can I get my child assessed for tics in Singapore?
Start with your GP or polyclinic for a referral to a paediatrician, and on to paediatric neurology at KK Women’s and Children’s Hospital or the National University Hospital if needed. Recording a video of the tics at home helps the doctor.
Does Tourette syndrome go away?
Often it eases a lot. By the late teens many young people have much milder tics and some have none, though a minority carry tics into adulthood.
Is Tourette’s caused by screens or parenting?
No. It’s a brain-based condition that runs in families. Screens and parenting don’t cause it. A separate rise in sudden functional tics in teenagers has been linked to watching tic videos online, and that’s assessed differently.
The thing to hold on to
A new tic in a young child is usually nothing, and even a confirmed Tourette’s diagnosis is rarely the disaster parents first imagine. The children who do best are the ones whose tics are met with calm rather than correction, whose schools are told, and whose other needs, the attention or the anxiety, are looked after alongside. If the tics are lasting, spreading to sounds, or wearing your child down, get them seen. Most of these children reach their teens with the tics fading and their confidence intact.
