Tic disorders and Tourette syndrome

Sudden, repeated movements or sounds that a person cannot stop. They usually begin in childhood, most settle within a year, and the ones that persist are manageable — but knowing which kind you are dealing with changes what to do about it.

If you are a parent reading this

Most tics in children are temporary. They typically appear around age five or six, wax and wane over weeks, and resolve within a year without any treatment at all.

Tics also get worse when a child is watched, corrected or told to stop — so the instinct to intervene usually makes things harder. What follows is written to help you tell the common, self-limiting kind from the ones worth assessing.

Usual onset
Around age 5 or 6. By definition, before 18.
Most resolve
Within a year, without treatment.
Persistent tics
Affect roughly 1 in 100.

What are tics?

Tics are sudden, rapid, repeated movements or sounds that a person cannot control. Movements of the limbs, face or other body parts are motor tics. Repeated sounds — grunting, sniffing, throat clearing — are vocal tics.

They are not deliberate, and they are not a habit that can simply be stopped. Many people describe a building sensation beforehand that the tic relieves, rather like the urge to scratch an itch. Tics can often be suppressed briefly, but the effort is tiring and the tics tend to come out afterwards — which is why a child may hold them in at school and release them at home.

They commonly get worse with stress, excitement, tiredness and illness, and better with calm absorption in something. That variability is normal and does not mean they are voluntary.

The three tic disorders, including Tourette syndrome

All three begin before age 18, and all three require that the tics are not explained by medication or another medical condition. What separates them is which tics are present and for how long.

Provisional tic disorder Under 12 months

  • One or more motor tics or vocal tics
  • Present for no longer than 12 months in a row
  • Began before age 18

This is the commonest situation by a wide margin, and the one most likely to resolve on its own.

Persistent (chronic) tic disorder Over 12 months

  • One or more motor tics or vocal tics — but not both
  • Occurring on and off for more than a year
  • Began before age 18

The distinction from Tourette syndrome is simply that one type of tic is present, not both.

Tourette syndrome Both types, over 12 months

  • Two or more motor tics and at least one vocal tic, though not necessarily at the same time
  • Tics present for at least a year
  • Began before age 18

Tourette syndrome is not degenerative — it does not worsen progressively, and life expectancy is normal. Tics often peak in early adolescence and improve through the late teens and twenties.

A note on what Tourette syndrome is not. The involuntary swearing shown in film and television occurs in only a small minority of people with the condition. Most tics are blinking, shrugging, sniffing or throat clearing, and most people with Tourette syndrome go unrecognised by those around them.

What often comes with tics

Tics frequently occur alongside other things, and for many families those turn out to matter more day to day than the tics themselves:

  • Attention difficulties and hyperactivity
  • Obsessive or compulsive behaviour
  • Anxiety
  • Difficulty with sleep
  • Learning difficulties

Assessing these alongside the tics is part of getting the picture right, because addressing them often reduces the tics as well.

How tic disorders are diagnosed

Diagnosis is clinical — based on the history and on observing the tics, against the criteria above. There is no test that confirms a tic disorder.

Investigation is used to exclude other causes where something in the picture is unusual:

  • Blood tests — where a metabolic or other medical cause is possible
  • MRI — where the presentation is atypical, the onset sudden, or the examination abnormal
  • EEG — where the movements could be seizures rather than tics

Some presentations warrant assessment sooner rather than later: tics beginning in adulthood rather than childhood, a sudden and dramatic onset, movements accompanied by weakness or loss of coordination, or tics following a head injury or serious illness. Those are not typical, and they need a cause established.

What actually helps

Treatment is not automatic. Tics are treated when they interfere with daily life, cause pain, or cause distress at school or work — not simply because they are visible.

Education and adjustment, first

For many children this is the whole treatment. Explaining tics to teachers and classmates, allowing a discreet way to leave the room, not drawing attention to tics, and reducing the pressure to suppress them all lower the burden considerably. Being told to stop reliably makes tics worse.

Behavioural therapy

Structured behavioural approaches — habit reversal training and comprehensive behavioural intervention for tics — teach recognition of the build-up before a tic and a competing response to use instead. This is first-line treatment where treatment is needed, ahead of medication, and it is delivered by a trained therapist rather than a surgeon.

Medication

Considered where tics are causing significant difficulty and behavioural approaches have not been enough. Several classes are used; all involve balancing benefit against side effects, which is why they are not a first step.

Managing what comes alongside

Treating attention difficulties, anxiety, obsessive-compulsive symptoms or poor sleep frequently reduces the tics too, and usually improves daily life more than targeting the tics directly.

Where this clinic fits

Most tic disorders are not neurosurgical, and it would be misleading to suggest otherwise. Ongoing care sits with paediatric neurology, psychiatry and behavioural therapy, and for the large majority of children that is the right and only care needed.

A neurological assessment here is worth having in narrower circumstances:

  • Tics that began in adulthood, which is unusual and warrants a cause being established
  • A sudden or dramatic onset, rather than the typical gradual appearance
  • Movements accompanied by weakness, numbness or loss of coordination
  • Tics following a head injury or a serious illness
  • Where it is unclear whether the movements are tics at all — seizures, tremor and other movement disorders can look similar

In those situations the value is the examination and, where indicated, imaging — establishing what is causing the movements before deciding what to do about them. If it turns out to be a straightforward tic disorder, you will be told so and pointed to the people who manage it best.

Living with tics

Tics fluctuate. They come in bouts, change in form over months, and are worse at some periods than others. A bad few weeks does not mean the condition is progressing.

For children, the most useful things a parent can do are practical: keep school informed, protect sleep, avoid making the tics a subject of correction, and watch the pattern over months rather than days. Tics that have been absent for over a year rarely return in force, though roughly one child in three who has had tics will have some over the following five to ten years.

Common questions

Will my child grow out of it?

Most do. The majority of childhood tics resolve within a year, and even where they persist, tics typically peak in early adolescence and improve through the late teens and twenties.

Should I tell my child to stop?

No. Tics are involuntary, and being watched or corrected reliably makes them worse. Suppressing them takes effort that has to be released later, which is why tics are often worse at home than at school.

Does having tics mean Tourette syndrome?

No. Tourette syndrome requires both motor and vocal tics present for over a year. Most children with tics have neither the combination nor the duration, and have a provisional tic disorder that resolves.

Do tics need treating?

Only when they interfere with daily life, cause pain, or cause distress. Visible tics that do not bother the person having them are often best left alone, with the effort going into how others respond instead.

Can tics start in adulthood?

It is unusual. Tic disorders are defined by onset before 18, so movements beginning in adulthood warrant assessment to establish what is causing them rather than being assumed to be tics.

Do I need a referral?

No. Bring a record of what the movements look like, when they started and how they have changed — a phone video is genuinely useful, because tics often do not appear during an appointment.

If the movements began in adulthood, came on suddenly, or come with other neurological symptoms, an assessment is worth having. Bring a video.
