Tics are fast, repetitive muscle movements that result in sudden and difficult to control body jolts or sounds.

Occasional neuromuscular symptoms: tics, twitches, fasciculations, spasms, cramps, restless legs.

They're fairly common in childhood and typically first appear at around 5 years of age. Very occasionally they can start in adulthood.

Tics are not usually serious and normally improve over time. But they can be frustrating and interfere with everyday activities.

1. Motor tics refer to movement-based tics while phonic tics are associated with sound production. Further, motor tics can be simple motor tics or complex motor tics. Similarly, phonic tics can be simple phonic tics or complex phonic tics. In simple tics, a single muscle group is involved, while in complex tics, more than one muscle group is involved.

Tourette's syndrome, a term that's used when tics have lasted for more than a year, is covered separately.

Types of tics

There are many types of tic. Some affect body movement (motor tics) and others result in a sound (vocal or phonic tics).

Examples of tics include:

• blinking, wrinkling the nose or grimacing
• jerking or banging the head
• clicking the fingers
• touching other people or things
• coughing, grunting or sniffing
• repeating a sound or phrase – in a small number of cases, this may be something obscene or offensive

Tics can happen randomly and they may be associated with something such as stress, anxiety, tiredness, excitement or happiness. They tend to get worse if they're talked about or focused on.

They often start with an unpleasant sensation that builds up in the body until relieved by the tic – known as an urge – although they can sometimes be partly suppressed.

When to see a GP

Tics are not usually serious and they do not damage the brain.

You do not always need to see a GP if they're mild and not causing problems. Sometimes they can disappear as quickly as they appear.

See a GP if you're concerned about your or your child's tics, you need support or advice, or the tics:

• occur very regularly, or become more frequent or severe
• cause emotional or social problems, such as embarrassment, bullying or social isolation
• cause pain or discomfort (some tics can cause the person to accidentally hurt themselves)
• interfere with daily activities, school or work
• are accompanied by anger, depression or self harm

A GP should be able to diagnose a tic from a description of it and, if possible, seeing it. Recording a short video can be helpful, but be careful not to draw too much attention to the tic while filming as this can make it worse.

Treatments for tics

Treatment is not always needed if a tic is mild and is not causing any other problems. Self-help tips, such as avoiding stress or tiredness, are often very helpful for the majority of people.

If a tic is more severe and is affecting everyday activities, therapies that aim to reduce how often tics occur may be recommended.

Occasional Tics Treatment

The main therapies for tics are:

• Habit reversal therapy – this aims to help you or your child learn intentional movements that 'compete' with tics, so the tic cannot happen at the same time
  • Comprehensive behavioural intervention for tics (CBiT) – a set of behavioural techniques to help learn skills to reduce tics
• Exposure with response prevention (ERP) – this aims to help you or your child get used to the unpleasant sensations that are often felt just before a tic, which can stop the tic occurring

There are also medicines that can help reduce tics. These may be used alongside psychological therapies or after trying these therapies unsuccessfully.

How long do tics last?

In most cases, tics improve over time or stop completely.

Sometimes they may just last a few months, but often they come and go over several years.

They are normally most severe from around 8 years of age until teenage years, and usually start to improve after puberty.

Causes of tics

It's not clear what causes tics. They're thought to be due to changes in the parts of the brain that control movement.

Occasional Tics Disorder

They can run in families, and there's likely to be a genetic cause in many cases. They also often happen alongside other conditions, such as:

Tics can sometimes be triggered by taking illegal drugs, such as cocaine or amphetamines, and are occasionally caused by more serious health conditions such as cerebral palsy or Huntington's disease.
