A child who suddenly starts blinking repeatedly, clearing their throat every few seconds, or making small jerking movements with their shoulder can be alarming to watch. Many parents worry about brain problems, epilepsy, or Tourette syndrome. The reality is that transient tics are common — far more common than most people realise — and the majority disappear on their own within a few months.
The main intervention that helps in mild and moderate tic disorders is not medication. It is education: helping families, schools, and the child themselves understand what tics are, why drawing attention to them makes them worse, and why the child's experience of needing to suppress them is genuinely uncomfortable rather than optional.

What Tics Are
Tics are brief, repetitive, stereotyped movements (motor tics) or sounds (vocal/phonic tics) that occur suddenly, are usually not preceded by a specific voluntary intention, and are difficult to fully suppress. They are not random — the same tic in the same individual tends to occur in the same pattern.
Many people with tics describe a premonitory urge — a build-up of tension, discomfort, or an "itch" sensation in the body that precedes the tic, which is temporarily relieved by performing it. The urge to tic is described by many as being similar to the urge to blink when a piece of dust enters the eye — possible to suppress briefly, but uncomfortable and not sustainable. This premonitory urge is not present in young children but often develops in middle childhood.
Motor tics include: eye blinking, grimacing, head jerking, shoulder shrugging, sniffing, mouth opening, and more complex sequences involving multiple muscle groups. Vocal tics include: throat clearing, sniffing, humming, grunting, or more complex vocalisations including syllables or words. Coprolalia (involuntary utterance of obscene words) is associated with Tourette syndrome but occurs in only around 10 per cent of those affected, contrary to popular perception.
Classification
Transient tic disorder: single or multiple tics, motor and/or vocal, lasting less than twelve months. Very common — approximately 20 per cent of children experience transient tics at some point. Typically starts between ages five and seven; more common in boys.
Persistent (chronic) tic disorder: motor or vocal tics (not both), lasting more than twelve months.
Tourette syndrome (TS): multiple motor tics and at least one vocal tic, persisting for more than twelve months, with onset before age eighteen. Affects approximately 0.5 to 1 per cent of the population. Tics must cause distress or functional impairment for the diagnosis to be given.
What Affects Tics
Tics wax and wane. They are typically worse during stress, anxiety, excitement, fatigue, and illness. They are often reduced during periods of focused concentration (such as reading or playing a video game, which requires directed attention). They are almost always absent during sleep.
Pointing out a tic, asking the child to stop, or drawing attention to it in the moment almost invariably makes the tic more frequent. This is because the attentional focus on the body sensation increases the premonitory urge. Schools and family members who comment frequently on tics inadvertently worsen them.
Associated Conditions
Tic disorders frequently co-occur with ADHD (found in approximately 60 per cent of those with Tourette syndrome) and obsessive-compulsive disorder (OCD, found in approximately 30 per cent). These co-occurring conditions often cause more functional difficulty than the tics themselves and should be assessed and treated separately if present.
PANS/PANDAS (Paediatric Acute-onset Neuropsychiatric Syndrome / Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections) is a controversial but recognised phenomenon in which sudden onset or acute worsening of tics and OCD symptoms follows streptococcal infection in some children. It remains under active investigation.
Management
For mild and transient tics, the primary approach is education and reassurance for the family and school, with a "watchful waiting" posture. Most tics resolve.
When tics cause significant distress, social difficulties, or functional impairment, Comprehensive Behavioural Intervention for Tics (CBIT) is the recommended first-line treatment. CBIT is a structured behavioural therapy that includes habit reversal training (building awareness of the premonitory urge and developing a competing response) and relaxation and function-based interventions. The largest randomised controlled trial (Wilhelm et al., 2012) found CBIT significantly superior to supportive therapy alone.
Medication is considered for severe or refractory tics. Options include clonidine (alpha-2 agonist, also helpful for co-occurring ADHD), aripiprazole, and, for severe cases, tiapride or haloperidol. Medication reduces tic frequency rather than eliminating tics and is used alongside rather than instead of behavioural approaches.
The Tourettes Action charity provides excellent UK-specific information and a schools toolkit for communicating about tics and Tourette syndrome to peers and staff.
Key Takeaways
Tics are sudden, repetitive, non-rhythmic movements or sounds that are difficult to suppress and are not under full voluntary control. They are common in childhood, affecting approximately 20 per cent of children at some point. Most childhood tics are transient, lasting less than twelve months, and require no treatment. Tourette syndrome is defined by the presence of both multiple motor and at least one vocal tic persisting for more than twelve months. Tics are typically worsened by stress and anxiety and suppressed (temporarily) with concentration. Management is primarily education and reassurance; behavioural therapies (CBIT) are first-line treatment when tics cause significant distress or functional impairment.
