Does your child have Tourette syndrome, the same condition singer Billie Eilish has?

American singer-songwriter Billie Eilish in a recent interview spoke about the exhaustion that comes with living with Tourette Syndrome (TS). The nervous system disorder that results in tics begins to present in kids as young as three years old.

The US Centers for Disease Control and Prevention (CDC) puts the number of people with a lifetime diagnosis of tics – some disappear over time - to 3 cases per 1,000.

Wondering if your child’s behaviour qualifies for a TS diagnosis? Read on. We spoke to Dr Vivek Mundada, Consultant Paediatric Neurologist, UAE-based Medcare Women and Children Hospital, about what TS means for a child and who is at risk of getting the condition. This is what he had to say:

Tourette Syndrome (TS) is a condition of the nervous system resulting in ‘tics’, or sudden unintentional movements or sounds.

It may present in a number of ways:

Most people with Tourette syndrome have combination of two or more motor tics as well as vocal tics. Such tics occur many times a day and over a period of more than a year. That's when a neurologist can diagnose the syndrome. For most people, Tourette syndrome starts between the ages of three and nine, with tics generally peaking at around the ages of 10 to 13.

[In the case of Grammy-winner Eilish, she was diagnosed at age 11; she is currently 20.]

Actually, no. Many studies have shown that boys are more likely to develop tics and Tourette syndrome than girls. Many children can have associated neuropsychiatry or neurodevelopmental conditions alongside this condition, too, such as:

The exact cause of Tourette syndrome is still not known. However, the condition tends to run in families, so genes do play a role. Results from Gilles de la Tourette syndrome (GTS) family studies consistently show a 10-to-100-fold increase in the rates of GTS in first-degree relatives when compared to those rates in the general population.

Tourette syndrome is diagnosed when someone has at least two motor tics and at least one vocal tic for more than 12 months. There's no single test for Tourette's syndrome. Tests and scans such as magnetic resonance imaging brain scan can be used to rule out other conditions.

Tics can occur anywhere in the body. The first motor tics tend to be of the face, and as we get older, tics move to other areas such as the neck, arms, legs and body.

Vocal tics tend to start off as simple tics. Common simple vocal tics include throat clearing, sniffing, snorting, and grunting. They can later become more complex and include words or sentences. This is when a person can say inappropriate things. Although sometimes it may look that they are saying it on purpose but it is done completely involuntarily.

That said, only 10 per cent of people who have Tourette syndrome swear. Tics that use bad language are known as coprolalia and most people with TS don’t have this tic. It is also uncommon for them to have other tics like copropraxia, which is the making of rude or unacceptable movements or gestures.

There is no cure for TS, but half of the young people diagnosed will see their symptoms reduce to the point where they seem to disappear or become easily manageable by the time they are 18. Tics can be worse if you are stressed, nervous, excited or anxious. So often curbing such anxiety with the help of a neuropsychologist can help.

Does your child have TS? Annette Du Bois, of UK-based confidence and emotions coaching Champs Academy, who works with children with TS, says first one must explain the situation or condition in a simplified medical way. “Get them to not see it as permanent (even if it might last a long time), but a condition that can improve over time.

“Prevent them from labelling themselves as the condition they currently have,” she says.

Du Bois lists the following strategies:
