Playing ice hockey is Luke's favorite thing to do. But when Luke has a game someplace
new, he often has to deal with stares and weird looks from strangers because he sometimes
shouts unexpectedly or blinks his eyes hard. To people who don't know him, it looks
like he's in pain or needs help. These tics are
symptoms of Luke's Tourette syndrome.
What Is Tourette Syndrome?
Tourette syndrome (TS) is a disorder that affects the
body's brain and nervous system by causing tics — sudden, repetitive movements
or sounds that some people make, seemingly without realizing it. A person with Tourette
syndrome has mulitple motor tics and at least one vocal tic.
Tics are actually more common in teens than you might think. You may know someone
who has either a motor tic (sudden, uncontrollable movements like exaggerated
blinking of the eyes) or a vocal tic (sounds such as throat clearing, grunting,
or humming).
Tourette syndrome is a genetic disorder, which means it's the result of a change
in genes that's either inherited (passed on from parent to child) or happens during
development in the womb. As with other genetic disorders, someone may have a tendency
to develop TS. But that doesn't mean the person will definitely get it.
The exact cause of Tourette syndrome isn't known, but
some research suggests that it happens when there's a problem with how nerves communicate
in certain areas of the brain. An upset in the balance of neurotransmitters (chemicals
in the brain that carry nerve signals from cell to cell) might play a role.
People with Tourette syndrome usually first notice symptoms while they're kids
or teens. TS affects people of all races and backgrounds, although more guys than
girls have the condition.
And, Tourette syndrome is not contagious. You can't catch it from someone who has
it.
What Are the Signs and Symptoms?
The main symptoms of Tourette syndrome are tics — multiple motor tics and
at least one vocal tic. Motor tics can be everything
from eye blinking or grimacing to head jerking or foot stomping. Some examples of
vocal tics are throat clearing, making clicking sounds, repeated sniffing, yelping,
or shouting. In rare cases, people with TS might have a tic that makes them harm themselves,
such as head banging.
At certain times, like when someone is under stress, the tics can become more severe,
happen more often, or last longer. Or, the type of tic may change.
Some people may be able to suppress their tics for
a short time. But tension builds, and it eventually has to be released as a tic. And
if a person is concentrating on controlling the tic, it may be hard to focus on anything
else. This can make it hard for teens with Tourette syndrome to have a conversation
or pay attention in class.
Many teens with Tourette syndrome also have other conditions like attention
deficit hyperactivity disorder (ADHD), obsessive-compulsive
disorder (OCD), learning disabilities, and anxiety.
