Tourette’s Syndrome

Tourette's SyndromeChildren sometimes develop funny “habit movements,” where they shrug their shoulders, jerk their head, or sniff repeatedly without reason.  If you ask the child why they’re moving that way, the answer is usually, “I dunno.”  These habits are called motor tics, and they typically go away on their own.

But not always.  Rarely the tics stick around or get worse.  And some kids develop strange verbal outbursts, where they’re compelled to bark, grunt, or say random words — usually at the worst of moments.  These sounds and misplaced words are called vocal tics.

When someone has both motor and vocal tics, they’re diagnosed with Tourette’s Syndrome.

Tourette’s isn’t all bad.  Although people with Tourette’s have an illness, they tend to be witty, quick, and bright.  They’re very organized and, despite their struggle with tics, thrive in jobs that require attention to detail.  Consider surgeon Morton Doran or jazz pianist Michael Wolff, both diagnosed with Tourette’s.  For more information about people who’ve thrived despite having this disorder, check out the article from about famous people with Tourette’s Syndrome (link opens in new window).

That said, here’s a little more information about this disorder.

Why is Tourette’s called Tourette’s?

As you guessed, the syndrome was named after Doctor Tourette, or Georges Albert Edouard Brutus Gilles de la Tourette.  That was way back in 1885.  During his experience in the hospital, Tourette noticed nine patients struggling with the same symptoms — motor and vocal tics — so he wrote a paper about it.  The publication caught the attention of the medical world, and his supervisors too.  They named the illness after him.

How common is the syndrome?

Tourette’s is part of a spectrum of tic disorders, and tic disorders are quite common.  Experts say that about 25% of children experience motor tics at some point during childhood, but the movements typically resolve on their own.  Tourette’s itself affects three in every 1000  children between 3 and 17 years of age.

The illness usually shows up in childhood, between ages 2 and 15, although average onset is 6 years of age.  Motor tics start before vocal tics.  The majority of kids worsen during their adolescent years, then improve once they reach adulthood.

What are the symptoms?

Tics are sudden, rapid, recurrent movements or sounds that are hard for the affected person to control.  They are not voluntary, since the person isn’t doing them on purpose, but they aren’t entirely involuntary either.  The individual can, with a lot of concentration, stop or delay the tics.  Unfortunately, once they’re allowed to return, tics come back full-force before returning to baseline.

As described before, there are two types of tics: motor and vocal.  People with Tourette’s have both, although not always at the same time.

  • Motor tics involve physical movement.  Subtypes include simple and complex motor tics.  Simple motor tics affect a limited number of muscles.  They’re small movements, like eye blinking, head jerking, facial grimacing, and shoulder shrugging.  Simple motor tics tend to be transient.  Complex motor tics involve multiple muscle groups, sometimes on both sides of the body. Examples of complex motor tics include hitting oneself, hopping, snapping fingers, or obscene gesturing with the pelvis.  Both types of motor tics are common in people with Tourette’s.
  • Vocal tics include bursts of sounds and expressed language.  Like motor tics, vocal tics are divided into simple and complex types.  Simple motor tics are limited to sounds (i.e. not words), like coughing, grunting, sniffing, or barking. Complex vocal tics are words or sentences, like swearing, repeating oneself or others, or singing a line of a song.  People with Tourette’s struggle with both simple and complex vocal types.

Tics can be debilitating.  Imagine attending church when you’re driven to make obscene gestures or yell out blasphemous statements.  Sitting a full hour without moving or speaking can be exhausting.   Now transfer that problem over to work, school, movie theaters, dates,  doctor’s waiting rooms, and a whole days’ worth of social interactions… it’s an enormous problem.

Tics also tend to “want to do” the opposite to what’s socially accepted, as though there’s a little man inside the brain who’s always thinking, “What’s scandalous thing can I do right now?”  Fortunately, tics do tend to wax and wane.

(Part of the official diagnosis: symptoms of Tourette’s start before 18 years of age.  They happen several times/day for at least one year and aren’t caused by medications, substance abuse, or medical problems.)

What triggers a tic?

Scientists don’t know what causes Tourette’s Syndrome, not the actual biological or environmental trigger that is responsible, but it seems to run in families, suggesting a genetic cause; specific genes haven’t been identified yet.

But what triggers tics on a day-to-day basis?  While stress, exhaustion, and excitement worsen symptoms, the incentive that drives a tic seems to be an internal one: those affected by the illness describe having an uncomfortable feeling, like a tickle or sense of tension, that intensifies until they give into the tic.  The need to avoid this tension is what drives the behavior.

What other symptoms are seen? 

People with this syndrome often struggle with other disorders, including obsessive compulsive disorder (OCD), attention problems (ADHD), depression, anxiety, social phobia, and autism spectrum disorder.

OCD is very common.  The obsessive part of OCD involve unwanted, intrusive thoughts that cause distress to the person experiencing them.  The compulsive aspect include rituals that must be performed right away to avoid anxiety or something bad from happening.  Both OCD and Tourette’s are driven by certain “feelings,” but the sensations are very different.  OCD symptoms are triggered by emotion, typically panic, anxiety, and angst.  Tics are performed to avoid a tickling or tense sensation

How do you treat it? 

Tourette’s tends to vary from mild to profoundly problematic.  People with milder versions of the illness usually don’t need treatment.  When tics interfere with quality of life and ability to survive on a day-to-day basis, medical intervention is crucial.

Doctors use multiple approaches to control tics.  This includes medication and behavioral therapy.  Keep in mind there aren’t any cures for Tourette’s, but treatment can help dramatically.

  • Medications – Dopamine-blocking medications like antipsychotics are first line.  Examples include Prolixin, Haldol, and Risperdal.  Occasionally doctors recommend Botulinum (Botox) injections for tics that are limited to a small group of muscles.  Some studies suggest seizure medications like Topamax might be helpful.
  • Speech therapy — This can be helpful for individuals with multiple vocal tics.
  • Behavioral interventions – Habit-reversal training teaches people to control “urges” and abort a tic by moving in ways that are incompatible with the movement.  The theory is that abstaining from the tic makes it go away with time.
  • Deep brain stimulation (DBS) — Reserved for treatment-refractory Tourette’s, DBS involves planting a battery-operated medical device in the brain in areas that control movement.  By stimulating this part of the brain, the frequency of tics diminishes.
  • Other conditions —  If depression, anxiety, OCD, or any other mental health problem is present, it’s important to reach out for help. Psychiatrists can prescribe medications to diminish symptoms of OCD, depression, anxiety, or attentional symptoms.  Therapy offers a much-needed sounding board, plus an avenue to boost self-esteem, process stress or trauma, and gain support in dealing with tics.  Community support groups are a great way to meet other people struggling with the same problems.
