Tics in children are far more common than many parents realise. Transient tic disorders – brief periods of repetitive movements or sounds that resolve within a year – occur in around 10-20% of school-aged children. Tourette syndrome is a more persistent and complex form, but it too is more common than its public profile might suggest, and far better understood and manageable than it was even twenty years ago.
Part of what makes Tourette syndrome hard to navigate as a family is the cultural baggage: many people's understanding of the condition comes from dramatic media portrayals focused on coprolalia (involuntary swearing), which occurs in only about 10-15% of people with Tourette syndrome. Most children with the condition have tics that are unusual, sometimes stigmatised, but rarely involve offensive language. Getting past the stereotype to the reality of what the condition actually involves makes it much easier to support a child effectively.

Understanding Tics
Tics are sudden, rapid, repetitive, non-rhythmic movements or sounds that are experienced as semi-voluntary. That semi-voluntary quality is one of the defining features: most people with tics report a premonitory urge – a sensation of discomfort or tension in the part of the body about to tic – that is temporarily relieved when the tic is performed. This is quite different from truly involuntary movements like seizures. Some people can suppress their tics for periods of time, but suppression increases the urge and typically leads to a tic "rebound" later.
Motor tics can be simple (eye blinking, head jerking, shoulder shrugging, facial grimacing) or complex (sequences of movements such as touching objects, jumping, or making particular gestures). Vocal (or phonic) tics can be simple (sniffing, throat clearing, grunting, coughing) or complex (repeating words or phrases, echolalia – repeating others' words, coprolalia – which is the involuntary vocalisation of socially inappropriate words, present in a minority).
Tics wax and wane: they are typically worse during periods of stress, excitement, or fatigue, and often suppressed (involuntarily as well as voluntarily) in demanding or novel situations such as a doctor's appointment, which means a parent reporting severe tics may have a child who appears relatively tic-free in the consulting room.
Diagnostic Criteria
Tourette syndrome requires, under DSM-5 and ICD-11 criteria, both multiple motor tics and at least one vocal tic, present (though not necessarily continuously) for more than one year, with onset before age 18. Many children meet criteria for provisional tic disorder (tics for less than a year) or persistent (chronic) tic disorder (either motor or vocal tics but not both). Treatment and support principles are similar across the spectrum.
Prevalence and Course
Around 1% of school-aged children meet criteria for Tourette syndrome, and the condition is three to four times more common in boys than girls. This male predominance is consistent across studies and is thought to reflect biological factors including sex-hormone influences on dopaminergic pathways and basal ganglia function. Kirsten Müller-Vahl at Hannover Medical School and Jeremy Stern at St George's Hospital London have both contributed substantially to understanding adult and paediatric Tourette syndrome presentation and treatment.
The natural history is relatively reassuring: tics typically begin between ages 5 and 7, often with simple motor tics first (eye blinking is particularly common as an early tic). Severity peaks around ages 10-12 and substantially improves in most individuals during mid-to-late adolescence. Follow-up studies suggest that around 50-75% of children with Tourette syndrome experience significant reduction in tic severity by early adulthood, and many no longer meet diagnostic criteria. A minority continue to have significant tics in adulthood.
Co-occurring Conditions
The most clinically important thing to understand about Tourette syndrome is that the majority of the functional burden typically comes from co-occurring neurodevelopmental and psychiatric conditions, not from the tics alone. Around 50% of children with Tourette syndrome have ADHD, and around 25% have OCD. Anxiety disorders are common, as are sleep difficulties and rage episodes (sometimes called "Tourette rage" or, more formally, episodic dyscontrol).
For many children, the ADHD or OCD is more disabling than the tics themselves, and addressing these co-occurring conditions is at least as important as managing tics. This means comprehensive assessment at diagnosis is important to identify the full clinical picture.
Treatment Approaches
Not all tics require treatment. Many children with mild tics are best supported through education, reassurance, and school awareness – allowing the child to understand their condition and reducing stigma – without any active treatment of the tics themselves.
When tics are causing significant distress or functional impairment, treatment options include behavioural intervention and medication.
Comprehensive Behavioural Intervention for Tics (CBIT) is a first-line recommended treatment, supported by a randomised controlled trial published in JAMA by Douglas Woods at Texas A&M University (now Marquette) and colleagues in 2010 involving 126 children. CBIT combines habit reversal training (awareness training of the premonitory urge and a competing response) with a function-based assessment of tic-exacerbating situations. It is effective in reducing tic severity and has no side-effects. Access through the NHS can be limited; some families access CBIT through trained private therapists.
For children who need pharmacological treatment, the evidence supports alpha-2 agonists (clonidine and guanfacine) as first-line medications – they are also beneficial for co-occurring ADHD and have a milder side-effect profile than dopamine antagonists. For more severe tics, aripiprazole (an atypical antipsychotic and dopamine partial agonist) has good evidence and a better tolerability profile than older antipsychotics. Haloperidol and pimozide, once the mainstay of treatment, are now generally second or third line due to their side-effect profile. Risperidone is also used.
Deep brain stimulation (DBS) of the thalamic nuclei has been explored in severe, treatment-refractory adult cases; this is not routine for children.
School Support
Children with Tourette syndrome may need specific support at school. Tics can be disruptive in a classroom setting, both for the child and for other pupils. Teachers who understand the condition – that tics are not deliberate, that the child is not seeking attention, and that punishment or requests to stop are unhelpful and distressing – are invaluable.
Sitting the child near the front where tics are less visible to others, allowing the child to leave the room briefly if tic suppression is becoming overwhelming, and creating a supportive classroom culture are practical measures. For children with significant co-occurring ADHD or OCD, appropriate educational adjustments and, where needed, an EHC plan, provide a framework for sustained support.
Tourettes Action is the main UK charity for people with Tourette syndrome and their families, providing information, training for schools, and peer support.
Key Takeaways
Tourette syndrome is a neurodevelopmental condition characterised by multiple motor tics and at least one vocal tic, present for more than a year. It affects approximately 1% of school-aged children in the UK, with boys affected three to four times more commonly than girls. Tics typically begin between ages 5 and 7, peak in severity around 10-12, and substantially improve in most cases by late adolescence and adulthood. The majority of the burden associated with Tourette syndrome comes from co-occurring conditions – ADHD (in around 50%), OCD (in around 25%), and anxiety – rather than from the tics themselves. Comprehensive Behavioural Intervention for Tics (CBIT) is a recommended first-line treatment approach.
