Tourette Syndrome is a neurological condition, which means it's to do with the brain.

Scientists don't yet know what causes it but it is thought to do with an imbalance of brain chemicals such as dopamine, which send signals around the body.

TS is often inherited, which means it has been passed down from your parents or other relatives.

It is not infectious so you can't catch it.

Most people who have TS also have other complex conditions to cope with as well, such as ADHD, OCD and Autism.

The key symptoms of TS are called tics.

Tics are repeated movements and sounds that happen without someone's control.

Tics can occur in nearly any part of the body and in any muscle. Movement tics can include fast blinking or mouth twitches. Sound tics can include throat clearing and sniffing.

The biggest myth around TS is that everybody with the condition swears. However, only around 15 percent of people with Tourette's have this symptom. Most people with TS do not swear or curse because of the condition.

Someone with TS may be able to hold back their tics for a short time but eventually they have to let them out.

Tics can be brought on by anything at all but stress and anxiety are common triggers.

They can be helped with relaxation techniques or concentrating on an activity like playing the piano.

Lots of people have TS but most people have symptoms that are so mild they don't worry about them or may not even notice them.

It affects one school child in every hundred and is more common in boys.

More than 300,000 children and adults are living with TS in the UK, according to the charity Tourettes Action.

Tics usually start in childhood around the age of six to seven years and tic symptoms can change - the amount someone gets and how often they experience them - over time.

Most people with TS are not significantly affected by their tics or behaviours, and so do not need medication.

But there are medications which can help control the tics if they are causing problems.

People in the TS community also support the use of other ways to help them manage symptoms, including keeping a good diet, exercise and behavioural therapy.
