A facial tic is an
involuntary, uncontrolled spasm in the facial muscles. The tic is unwanted and
generally occurs regularly enough to be a nuisance to the person who
experiences it.
A person can hold in a tic
temporarily, in a similar way to holding in a sneeze, but doing so often makes
the person increasingly uncomfortable.
A few different disorders
can cause facial tics, but most of the time facial tics do not indicate a
severe medical condition.
According to a report
in Pediatric Neurology, facial tics occur more commonly in children
than adults, and boys seem to be much more likely to experience facial tics
than girls. Most children's facial tics fade after a few months.
What are facial tics?
Facial tics are involuntary
muscle movements that can happen anywhere in the face. However, they usually
occur in the same place each time and happen frequently enough to bother the
person. Severe tics can affect a person's quality of life.
Common types of facial tics
include:
- rapid eye blinking or winking
- squinting
- flaring the nostrils
- clicking the tongue
- sucking the teeth
- raising the eyebrows
- opening and closing the mouth
- scrunching the nose
- mouth twitching
As well as these muscular
tics, some people may also experience vocal tics, such as clearing the throat
or grunting.
A person may suppress a tic
temporarily, but it will come out eventually.
Types of tic disorders
Different types of
disorders can cause facial tics. The severity of the tic, as well as the
presence of other symptoms, can often help a doctor identify the underlying
condition.
Transient tic disorder
Transient tics are
temporary. Transient tic disorder may cause a regular facial or vocal tic, but
the tic typically lasts for under a year.
Transient tic disorder
usually only causes tics while a person is awake. People rarely have tics while
they are sleeping.
Transient tic disorder is
responsible for the majority of causes of tics in children. They usually
resolve without any treatment.
Chronic motor tic disorder
Chronic motor tic disorder
is a more persistent tic disorder. For a doctor to diagnose a person with
chronic motor tic disorder, they must have experienced tics for over a year,
for periods of at least 3 months at a time.
Unlike transient tic
disorder, chronic motor tic disorder causes tics that can also occur during
sleep.
Chronic motor tic disorder
can occur in both children and adults. Young children who have chronic motor
tic disorder may not need treatment, as symptoms may be more manageable or
subside on their own over time.
Adults who have the
disorder may need medication or other treatment to control the tics.
Tourette's syndrome
Tourette's syndrome, often
shortened to Tourette's, is a chronic condition that causes one or more motor
or vocal tics.
Most people who have
Tourette's syndrome develop it during childhood, but the disorder can continue
into adulthood. Tics usually become less severe as the person ages.
People with Tourette's
syndrome have both motor and verbal tics. They may make sounds or say words
involuntarily.
Some people with Tourette's
syndrome have only small motor tics, such as rapid blinking or throat clearing.
However, they may also have more involved motor tics, such as:
shrugging one or both
shoulders
- shaking the head uncontrollably
- flapping the arms
- saying inappropriate words
- making inappropriate gestures
- yelling out
People can often manage
symptoms of Tourette's syndrome by having behavioral therapy. However, people
who have any additional underlying conditions may need medication.
Treatment
Treatment for facial tics
can vary depending on the type and severity of the tic. Many tics, such as
those caused by transient tic disorder, may go away without treatment over
time.
Tics that interfere with
performance in school or at work may require treatment. Long-lasting, chronic
tics, such as those caused by Tourette's syndrome, may need more extensive
treatment.
Treatment for tics may
include:
Medication
Medication for tics include
classes of drugs called alpha-adrenergic agonists, neuroleptic drugs, and
dopamine blockers.
In cases of persistent
facial twitches or tics, doctors may recommend Botox
injections. Botoxinjections can paralyze the facial muscles for a few
months, which may be enough to stop a tic from coming back.
Medications can also help
treat any underlying conditions causing the tic, such as Tourette's syndrome
or ADHD.
