Tics — sudden, brief, repetitive movements or sounds — are common in school-age children and usually temporary. Dr. Anand Karnam explains when tics are benign, when they indicate Tourette syndrome, and what helps.
Key Points
- Tics are sudden, repetitive, non-rhythmic movements or sounds — usually transient in childhood.
- Tourette syndrome requires multiple motor tics AND at least one vocal tic for ≥1 year.
- Most tics in children peak at age 10–12 and reduce significantly by adulthood — many resolve completely.
- ADHD and OCD co-occur with Tourette's in 60–80% of cases — these often cause more impairment than the tics.
- Behaviour therapy (CBIT) is as effective as medication for tic suppression in motivated patients.

"Parents panic when they see their child start ticcing. I reassure them: transient tic disorder in childhood is common, usually self-limiting, and the child is unaware during most tics. The ADHD that often comes with it needs more attention than the tics themselves."
Tics — sudden, brief, repetitive, non-rhythmic movements or vocalisations — are among the most common neurological symptoms of childhood. Approximately 20% of school-age children develop some form of transient tic at some point. They are almost universally misunderstood by parents and teachers, often mistaken for deliberate bad behaviour or a nervous habit, and are the subject of unnecessary alarm. Understanding tic disorders helps parents respond appropriately and avoid inadvertently worsening the child's symptoms.
Types of Tics
Motor tics: Involuntary movements — eye blinking (the most common), head jerking, shoulder shrugging, facial grimacing, nose wrinkling. Vocal tics: Involuntary sounds — throat clearing, sniffing, grunting, coughing, humming. Both can be simple (single brief movement/sound) or complex (coordinated sequences of movements or meaningful words/phrases).
Tourette Syndrome
Tourette syndrome (TS) requires: both multiple motor tics AND at least one vocal tic; present for more than 1 year; onset before age 18. The often-depicted feature of coprolalia (involuntary swearing) occurs in only 10–15% of Tourette patients — it is not required for diagnosis and should not be associated with the condition. TS is strongly associated with ADHD (50–75% of TS patients have ADHD) and OCD (30–40% of TS patients). The tic disorder may be the least impairing aspect — managing ADHD and OCD is often the clinical priority.
Key Points for Parents
Tics worsen with anxiety, stress, excitement, and fatigue — not with deliberate intent. Tics reduce during focused activity (video games, reading) and during sleep. Telling a child to "stop doing that" increases the tic by drawing attention to it. Transient tic disorder (lasting less than 1 year) resolves spontaneously in the majority of children without any treatment. Treatment is indicated when tics cause significant distress or functional impairment: habit reversal training (first-line, evidence-based behavioural therapy); clonidine; guanfacine; in severe cases, aripiprazole or risperidone.
