Tic disorders and Tourette syndrome
Common, fluctuating movements and sounds that are involuntary — usually best helped by understanding, behavioural therapy and, when needed, medication.
Tics are sudden, repetitive movements (motor tics) or sounds (vocal tics) that a child feels compelled to make. They are common in childhood, typically start between ages 4 and 8, and naturally wax and wane. Tourette syndrome is diagnosed when multiple motor tics and at least one vocal tic have been present for over a year, with onset before age 18. Tics are not 'bad behaviour' and are largely involuntary; many children improve markedly by adulthood. Attention, anxiety and obsessive–compulsive features often accompany tics and sometimes affect a child more than the tics themselves.

What tics and Tourette syndrome are
Tics are brief, repetitive, stereotyped movements (such as blinking, head jerks, shrugging) or sounds (such as throat-clearing, sniffing, grunting). They are usually preceded by an uncomfortable urge and can be suppressed briefly, but doing so builds tension — which is why they are described as involuntary rather than deliberate.
When multiple motor tics and at least one vocal tic have been present for more than a year, with onset before age 18, the diagnosis is Tourette syndrome. The diagnosis is clinical — there is no specific test — and the tics characteristically come and go in waves over weeks and months.
Co-occurring difficulties
For many children, attention difficulties (ADHD), anxiety, and obsessive–compulsive features have a bigger day-to-day impact than the tics themselves. Recognising and supporting these is often the most helpful part of care.
Treatment
Many children need only reassurance and education — for the family and school — that tics are involuntary and not a sign of misbehaviour. When tics are troublesome, the first-line treatment with the best evidence is behavioural: Comprehensive Behavioural Intervention for Tics (CBIT), which includes habit-reversal training.
When medication is needed, options include alpha-2 agonists (clonidine, guanfacine — often helpful when ADHD coexists) and, for more severe tics, dopamine-modulating medicines (such as aripiprazole, risperidone or tiapride) or VMAT2 inhibitors. Botulinum toxin can help a single bothersome tic, and deep brain stimulation is reserved for rare, severe, treatment-resistant cases in adults.
How an educational review can help
An educational review can explain what is and isn't a tic, put the diagnosis and any co-occurring ADHD/OCD/anxiety in context, and clarify which treatments (behavioural versus medication) fit your child's situation — helping you prepare questions for your treating team. It is educational and does not replace your clinician's care.
