Tic Disorders in Children: What They Are and When to Worry

What tics are, how they are classified, and why drawing attention to them makes them worse.

Tics are sudden, repetitive movements or sounds — blinking, throat-clearing, shrugging, sniffing, head jerking. They are common in childhood and most are temporary. Tic disorders are classified mainly by how long tics have been present: provisional tic disorder when tics have lasted less than a year, and persistent motor or vocal tic disorder when they've lasted longer. Tourette syndrome requires both multiple motor tics and at least one vocal tic for over a year. Tics naturally wax and wane, and they increase with stress, excitement, tiredness, and with attention being drawn to them. Most children see improvement in late adolescence.3

What tics look like

Motor tics — blinking, eye rolling, nose scrunching, grimacing, head jerking, shoulder shrugging, arm or abdominal movements. Some are simple and brief; others are longer sequences that can look purposeful.

Vocal tics — throat-clearing, sniffing, coughing, grunting, humming, squeaking. Less commonly, words or phrases.

Two things confuse parents: vocal tics are frequently mistaken for illness — a child who clears their throat or sniffs constantly is often treated for allergies for months before anyone considers tics — and complex tics can look deliberate, read as a habit or attention-seeking when they're neither.

How tic disorders are classified

The main distinction is duration.

  • Provisional tic disorder — motor and/or vocal tics present for less than a year. This is the most common outcome by a wide margin.
  • Persistent (chronic) motor or vocal tic disorder — either motor or vocal tics (not both) present for more than a year.
  • Tourette syndrome — multiple motor tics and at least one vocal tic, present for more than a year, with onset before 18. See Tourette syndrome.

Practically: a child who has been ticcing for two months does not have Tourette syndrome, and may well not have any lasting tic disorder. Time is part of the diagnosis.

Waxing and waning

Tics fluctuate — frequency and intensity vary over weeks and months, and the specific tics change. This is the single most useful thing for a parent to understand, because a bad week is usually not a trend, a new tic doesn't mean things are worsening overall, and anything tried during a peak will appear to work as the tic naturally settles. Tics reliably increase with stress, excitement (including positive excitement), tiredness, and illness, and often decrease during focused activity.

Why not to comment on tics

Drawing attention to a tic reliably increases it — whether through correction, sympathetic noticing, mimicking, or asking a child to stop. The most helpful response is not to react: not ignoring the child, ignoring the tic. Pass this on to teachers, grandparents, and siblings. On suppression: older children can hold tics back briefly, and it's effortful — a child who suppresses all day at school will often tic considerably more at home. That's release, not deterioration, and not a reflection of home life.

When to seek assessment

Worth an appointment if tics have been present several months, are causing pain or interfering with school, are distressing or embarrassing your child, or you're unsure what you're seeing. Raise promptly if tics appeared suddenly and severely rather than emerging gradually, started shortly after an illness, come with other new neurological symptoms, or are causing self-injury.

Also ask about ADHD, OCD, and anxiety — these occur at high rates alongside tic disorders and are often more impairing than the tics themselves. See ADHD, OCD, and anxiety.

How are tic disorders treated?

For tics that aren't causing impairment, pain, distress, or social difficulty, watchful waiting and education is a legitimate approach, and most children improve in late adolescence. Where tics do interfere, Comprehensive Behavioral Intervention for Tics (CBIT) is the recommended first-line treatment, ahead of medication.

Frequently Asked Questions

Are tics common in children?

Yes. Tics are common in childhood and most are temporary. Provisional tic disorder — tics lasting under a year — is by far the most frequent outcome.

Does my child have Tourette syndrome?

Tourette syndrome requires multiple motor tics and at least one vocal tic, present for more than a year, with onset before 18. Tics present for a few months don't meet that definition.

Should I tell my child to stop?

No. Drawing attention to tics reliably increases them. Not reacting to the tic is the most helpful response, and worth passing on to teachers and family.

Why are tics worse in the evening?

Tiredness increases tics, and children who suppress tics at school often release them at home. That's not a reflection of home life.

Will the tics go away?

Most children see improvement in late adolescence: by early adulthood roughly three-quarters have greatly diminished tics and over a third are free of them.3 Separately, tics that have been present for less than a year are classified as a provisional tic disorder, and those frequently resolve on their own.

Can stress cause tics?

Stress doesn't cause tic disorders, but it reliably increases tics in a child who has them — as do excitement, tiredness, and illness.
