Tourette Disorder in Children
Overview
Tourette disorder (TD) is a
neurological disorder. It is also called Tourette syndrome. The disorder causes repeated
tics. Tics are sudden, uncontrolled vocal sounds or muscle jerks. Symptoms of TD often
start between ages 5 and 10. They usually start with mild, simple tics of the face,
head, or arms. Over time, a child may have different kinds of tics that may happen
more
often. They may also involve more parts of the body, such as the trunk or legs. And
they
may be more disruptive to daily life.
Causes
Most cases of Tourette disorder are
caused by genes. It is an autosomal dominant disorder. Autosomal means that the gene
is
not on a sex (X or Y) chromosome. Dominant means that only one copy of the gene is
needed to have the condition. A parent with TD or the gene for TD has a 1 in 2 chance
to
pass the gene on to each child.
In up to 1 in 20 children with TD, the disorder is not caused by genes. Possible causes
in these cases may be problems during pregnancy, low birth weight, head injury, carbon
monoxide poisoning, or inflammation of the brain (encephalitis).
Risk Factors
TD affects more boys than girls.
Symptoms
The most common symptoms are uncontrolled muscle movements. They may occur in the
face, neck, shoulders, torso, or hands. Examples include:
- Head jerking
- Squinting
- Blinking
- Shrugging
- Grimacing
- Nose-twitching
- Repeated foot tapping, leg jerking, scratching, or other movements
Complex tics include:
- Kissing
- Pinching
- Sticking out the tongue or lip-smacking
- Touching behaviors
- Making rude gestures
TD also includes one or more vocal
tics, such as:
- Grunting or moaning sounds
- Barking
- Tongue clicking
- Sniffing
- Hooting
- Saying rude things
- Throat clearing, snorting, or coughing
- Squeaking noises
- Hissing
- Spitting
- Whistling
- Gurgling
- Echoing sounds or phrases
repeatedly
Tic behaviors change over time.
They also vary in how often they occur.
TD can occur differently in boys
and girls. Boys are more likely to have long-term (chronic) tics. Girls are more likely
to have obsessive-compulsive disorder (OCD). This is an anxiety disorder. With OCD,
a
child has a repeated thought, fear, or worry (obsession) that they try to manage through
a certain behavior (compulsion) to reduce the anxiety.
Not everyone with the gene will
have symptoms of Tourette disorder. If a parent passes the gene to a child, the child
may not have any symptoms. If a daughter inherits the gene, there is a 7 in 10 chance
that they will have at least one sign of TD. If a son inherits the gene, there is
an
almost sure chance (99%) that they will have at least one sign of TD.
The symptoms of TD can seem like
other health conditions. Have your child see their healthcare provider for a
diagnosis.
Diagnosis
A child with TD is usually
diagnosed around the age of 7. A primary care provider, pediatrician, child
psychiatrist, or a mental healthcare provider may diagnose your child. The healthcare
provider will ask about:
- Your child’s symptoms and health
history
- Your family’s health history
- Developmental problems
The healthcare provider will
also:
- Watch your child's behavior
- Ask for a history of your child's
behavior from teachers
- Assess your child’s psychological,
social, and educational status
A diagnosis of Tourette disorder needs the presence of different tics
for at least one year.
Treatment
Treatment will depend on your
child’s symptoms, age, and general health. It will also depend on how bad the condition
is. Some children may not need treatment. A child with TD can usually function well
at
home and in a regular classroom.
In some cases, a child may need special classes, psychotherapy, or medicine. These
may be choices if:
- Tics cause problems with daily function or school
- Your child has a problem, such as OCD
or attention deficit/hyperactivity disorder (ADHD)
- Your child has another emotional or
learning problem
A treatment called comprehensive
behavioral intervention for tics can help children deal with tics and reduce tics.
Your child may need medicines if
they have related conditions such as ADHD, OCD, or a mood disorder. Talk with your
child’s healthcare providers about the risks, benefits, and possible side effects
of all
medicines.
Complications
Many children who have TD also have
attention problems. Some have trouble in school. But most have normal intelligence
and
don’t have a learning disability.
Other conditions commonly seen in children with TD include behavior problems, mood
changes, social challenges, and trouble sleeping.
Prevention
Your healthcare provider may advise genetic counseling. You can discuss with a counselor
the risk for Tourette disorder in a future pregnancy.
Living with
Your child may need support and
help with:
- Self-esteem
- Relationships with family and
friends
- Classroom participation
Develop a strong, positive
relationship with your child's educational team. Depending on how bad the disorder
is,
they can both support your child in the classroom and also help with social situations.
As your child gets older, pay attention to social media and possible issues with
bullying. Seek professional counseling for your child and their siblings to help deal
with the emotional impact of Tourette disorder. Talk with your child’s healthcare
provider and school staff about the best ways to support your child.
Tourette disorder has no cure, and the condition is lifelong. It does
not get worse over time. And some children see their tic symptoms decrease in their
late teens and early 20s. People with Tourette disorder also have a normal life
expectancy. Tic symptoms tend to decrease with age, but ADHD, OCD, depression,
generalized anxiety, panic attacks, and mood swings can continue and cause ongoing
problems in adult life.
When to Call a Healthcare Provider
Call the healthcare provider if your child has:
- Symptoms that don’t get better, or get worse
- New symptoms

Next Steps
Tips to help you get the most from a visit to your child’s healthcare provider:
- Know the reason for the visit and what you want to happen.
- Before your visit, write down questions you want answered.
- At the visit, write down the name of a
new diagnosis and any new medicines, treatments, or tests. Also write down any new
instructions your provider gives you for your child.

- Know how you can contact your child’s
healthcare provider after office hours. This is important if your child becomes ill
and you have questions or need advice.
