What is Tourette Syndrome?

Tourette syndrome, simply put caused by repeated involuntary vocal as well as physical movements called TICs. In medical terms, Tourette Syndrome is a neurological disorder. It is named for Dr. Georges Gilles de la Tourette, a French neurologist who first described the condition in 1885.

Here is a quick snapshot of Tourette Syndrome:

  • Prevalence: 1 out of every 2,500 people in U.S have either 
  • Gender Bias: Girls are outnumbered by boys in ratio of 3:1
  • Tics:
  • Begin before age 21: Diagnosed between 3 to 9 years of age in most cases
  • Change in frequency, location and severity over period of time
  • Lasts a lifetime, though symptoms may become mild with age
  • Must be persistent for at least 1 year for confirmed diagnosis
  • May co-exist with other neurobehavioral disorders

Tourette Syndrome Symptoms

Symptoms of Tourettes are first noticed in children when they are between 3 to 9 years of age. Tourettes has no racial or ethnic bias, however, males are affected three to four times more often than females. Tourettes is a chronic condition and its symptoms can last a lifetime. The worst time for those suffering from Tourettes is in their early teens when TIC activity reaches its height. Motor TICs include blinking, shoulder movements or shrugs, lip licking, mouth breathing, sticking the tongue out and stretching movements, and then begin improving with age.

What is TIC Disorder?

Tics fall in two categories, simple and complex. Simple tic movements are those mentioned above while complex tic are distinct, coordinated patterns of movement, usually involving several muscle groups. Sometimes, complex tics exhibit what appears to be a normal reaction like touching or smelling items. Complex tics include repetitive words and phrases whereas simple tics are just a light gabbling of noise.

Some of the most complex Tourette Syndrome symptoms include motor movements that are self-inflicting (harming self) such as punching oneself or uttering inappropriate words and phrases called coprolalia. Coprolalia is only present in approximately 10 to 15% of those diagnosed with Tourette’s Syndrome. Tics remain while the child is sleeping. Certain physical experiences, such as having to wear a tie or tight clothing, can often worsen daytime tics.

Tics or Tourette syndrome symptoms can vary in type, body location, frequency, severity and can often appear to come and go. Usually, the first symptoms are noticed in the head and neck area. They can progress to include the muscles of the body extremities. Tics involving motor skills generally appear before tics involved with speech and communication. Only 10% of those affected with tics are disabled going into adulthood. Tics tend to improve as the person moves from their teen years to adulthood.

Can Tourette Syndrome Symptoms be Suppressed?

Although the symptoms of TS are involuntary, some subjects can suppress, camouflage, or otherwise manage their tics in an effort to minimize their impact while on day to day social interactions. However, people with TS often report a substantial buildup in tension and anxiety levels while suppressing their tics to the point where they feel that the tic must be expressed (against their will). Tics in response to an environmental trigger can appear to be voluntary or purposeful, but are not.

What causes Tourette Syndrome?

Tics impacted Brain Areas

The exact cause of Tourette syndrome is still unknown, yet research till date points to abnormalities in different brain regions such and the frontal lobe, basal ganglia, and cortex. These are the areas that connect the neurotransmitters like dopamine serotonin and norepinephrine which are all responsible for communication between the cells.

Present day evidence from twin studies suggests that Tourette syndrome might be an inherited disorder. The pattern of inheritance is very complex. Genetic studies have linked some forms of Attention Deficit Hyperactivity Disorder and OCD to Tourette’s Syndrome. However, most of the other neurobiological disorders have not yet been linked.

The gender of the child also plays a very valuable role in the Tourette Syndrome gene expression. Males are 3 times more likely to have tics while females are more likely to have OCD symptoms. Therefore, genetic counseling is important for individuals who have any potential hereditary conditions.

Tourette Syndrome Diagnosis

The possibility of a range of potential co-existing disorders closely related to Tourette syndrome makes it even more difficult to diagnose. Most individuals suffering from Tourettes Syndrome also have other neurobehavioral problems that cause more debilitating impairments than the tics. Some of common the co-existing diagnosis are:

  • Learning Disabilities: problems with schoolwork such as reading, writing and mathematics
  • Obsessive Compulsive disorder (OCD): For example, repetitive hand washing and having to have order and arrange things often overshadows the Tourette’s.

Physicians certify a confirmed diagnosis only upon verification that the child has both motor and vocal tics for at least one year. It is very common for children to receive the formal diagnosis of Tourette syndrome well into their early teen years.

Is Tourette Syndrome Treatable?

There is effective medication to treat some of the conditions that co-exist with Tourette’s Syndrome. Some medications, however, cause the tics to become more severe. Behavioral treatment and training can also help to reduce the wrongful diagnosis of Tourette Syndrome and help to unearth other co-existing disorders. Supportive therapy may help a child with Tourette Syndrome to better cope with the disorder and deal with the secondary or co-existing social and emotional problems.

Although there is no cure for TS, the condition seems to improve between the ages of 16-20. As a result, some may actually become symptom-free or no longer need medication for tic suppression. Although the disorder is generally lifelong and chronic, it is not a degenerative condition. Individuals with TS have a normal life expectancy. Also, Tourette syndrome does not impair intelligence.

Note: Though tic symptoms tend to decrease with age, it is possible that co-existing neurobehavioral disorders such as ADHD, OCD, generalized anxiety, depression, mood swings and panic attacks can still cause impairment in adult life.

Tourette Syndrome Treatment

There are treatments to help manage the tics caused by Tourettes Syndrome to assist patients carry out normal activities. Help is available in the form of Medications and behavioral therapy to limit the interference of tics (causing pain or anxiety) in daily life. Often, the people around someone with Tourette Syndrome do not realize that tics are something that the person cannot control and they are not being disruptive on purpose. Informing people about tics associated with Tourette’s syndrome often helps the person feel less anxious and the tics tend to lessen.

Since it is very common for someone with Tourettes Syndrome to have co-existing conditions such as Attention Deficit Disorder and ADHD, personalized treatment plans must be developed based on individual symptoms. Here is a list of what is commonly prescribed as treatment for those with Tourette Syndrome:

Presently the National Institute of Neurological Science and Stroke (NINDS), is responsible for supporting and conducting research in the area of Tourettes syndrome and other Communication Disorders. They also provide funds for professionals to be trained in Tourettes syndrome research and there ably. Learning and research about Tourette Syndrome treatment comes from studies across a varied number of medical and scientific disciplines. Some of these disciplines include genetics, neuroimaging, neuropathology, clinical trials, epidemiology, neurophysiology, neuro-immunology, and descriptive/diagnostic clinical science.
