Tourette Syndrome

(Other Health Impairment)

DEFINITION

Our nation’s special education law, the Individuals with Disabilities Education Act (IDEA) includes Tourette Syndrome under “other health impairment,” which means…

“…having limited strength, vitality, or alertness, including a heightened alertness to environmental stimuli, that results in limited alertness with respect to the educational environment, that is due to chronic or acute health problems such as asthma, attention deficit disorder or attention deficit hyperactivity disorder, diabetes, epilepsy, a heart condition, hemophilia, lead poisoning, leukemia, nephritis, rheumatic fever, sickle cell anemia, and Tourette syndrome; and adversely affects a child’s educational performance.”

[34 code of Federal Regulations §300.8(c)(9)]

OTHER DEFINITIONS

Tourette syndrome (TS) is a neurological disorder characterized by repetitive, stereotyped, involuntary movements and vocalizations called tics. The first symptoms of TS are almost always noticed in childhood. Some of the more common tics include eye blinking and other vision irregularities, facial grimacing, shoulder shrugging, and head or shoulder jerking. Perhaps the most dramatic and disabling tics are those that result in self-harm such as punching oneself in the face, or vocal tics including coprolalia (utter swear words) or echolalia (repeating the words of phrases of others). Many with TS experience additional neurobehavioral problems including inattention, hyperactivity and impulsivity, and obsessive-compulsive symptoms such as intrusive thoughts/worries and repetitive behaviors.

TYPES

Tourette Syndrome is one type of Tic Disorder. Tics are involuntary, repetitive movements and vocalizations. They are the primary symptoms of a group of childhood-onset neurological conditions known collectively as Tic Disorders and individually as Tourette Syndrome (TS), Persistent (Chronic) Motor or Vocal Tic Disorder, and Provisional Tic Disorder.

These three Tic Disorders are named based on the types of tics present (motor, vocal/phonic, or both) and by the length of time that the tics have been present. Below are the criteria that a doctor or other health care professional will use to diagnose TS or other Tic Disorders. There is no test to confirm the diagnosis of Tic Disorders, but in some cases, tests may be necessary to rule out other conditions.

Tourette Syndrome (TS), also known as Tourette’s Disorder: 1) At least 2 motor tics and at least 1 vocal (phonic) tic have been present, not necessarily at the same time. 2) Tics may wax and wane in frequency but have occurred for more than 1 year. 3) Tics started to appear before the age of 18. 4) Tics are not caused by the use of a substance or other medical condition.

Persistent (Chronic) Motor or Vocal Tic Disorder: Either motor tics OR vocal tics have been present for more than 1 year; cannot be both motor and vocal tics.

Provisional Tic Disorder: Motor and/or vocal tics have been present for less than 1 year, and have not met the criteria for TS, persistent (chronic) motor, or vocal tic disorder.

FACTS AND STATS

The current estimates are that 1 out of every 160 children between the ages of 5-17 in the United States has TS and that 1 out of every 100 children has TS or another Tic Disorder. Using 2010 US Census data, it is estimated that approximately 300,000 children in the US is affected by Tourette.

(TSA, 2019)

CAUSES

The causes of Tourette and other Tic Disorders remain unknown. The conditions are hereditary and so genetics clearly play a role in many, if not most or all, occurrences of the conditions. Environmental, developmental or other factors may also contribute to these disorders but, at present, no specific agent or event has been identified. Therefore, TS and Tic Disorders are likely to be caused by complex interactions between genetic and other factors which may vary in different individuals. Studies are underway to find the genes and other factors underlying the development of these disorders.

(TSA, 2019)

PREVENTION

There is no known prevention for tic disorders or Tourette.

CHARACTERISTICS AND DIAGNOSIS

For the diagnosis of Tourette syndrome, both multiple motor tics and vocal tics should have been present at some time during the disorder, although no necessarily concurrently; tics should occur many times a day (usually in bouts), nearly every day, or intermittently throughout a span of more than one year; a tic-free period of more than 3 consecutive months does not occur; onset is before 18 years of age; and the disorder is not due to the direct physiological effects of a substance or general medical condition.

Motor Tics

Motor tics are movements. Simple motor tics include but are not limited to: eye blinking, facial grimacing, jaw movements, head bobbing/jerking, shoulder shrugging, neck stretching, and arm jerking. Complex motor tics involve multiple muscle groups or combinations of movements and tend to be slower and more purposeful in appearance (i.e. hopping, twirling, jumping).

Vocal/Phonic Tics

Vocal (phonic) tics produce a sound. Simple vocal tics include but are not limited to sniffing, throat clearing, grunting, hooting, and shouting. Complex vocal tics are words or phrases that may or may not be recognizable but that consistently occur out of context. In 10-15% of cases, the words may be inappropriate (i.e. swear words, ethnic slurs, or other socially unacceptable words or phrases). This type of vocal tic, called coprolalia, is often portrayed or mocked in the media as a common symptom of TS.

Tics typically emerge between the ages of 5-7 years, most often with a motor tic of the head and neck region. They tend to increase in frequency and severity between the ages of 8-12 years. Most people with TS show noticeable improvement in late adolescence, with some becoming tic-free. A minority of people with TS continue to have persistent, severe tics in adulthood.

Tics can range from mild to severe and, in some cases, can be self-injurious and debilitating. Tics regularly change in type, frequency, and severity—sometimes for reasons unknown and sometimes in response to specific internal and external factors, including stress, anxiety, excitement, fatigue, and illness.

MEDICAL TREATMENT

There is no cure for Tourette syndrome, but thanks to years of dedicated research, there are various treatment options. Because tic symptoms do not often cause impairment, the majority of people with TS require no medication for tic suppression. However, effective medications are available for those whose symptoms interfere with functioning. There is no one medication that is helpful to all people with TS, nor does any medication completely eliminate symptoms. Effective medications are also available to treat some of the associated neurobehavioral disorders that can occur in patients with TS.

(NINDS, 2019)

When tics become problematic or interfere with daily functioning, behavioral treatment or medication may be considered.

Because each patient is unique, the individual or family should work with a clinician to determine an appropriate treatment plan. It may take some time and patience to determine the most effective approach. A clinician may recommend first treating one of the co-occurring conditions if it is more bothersome or problematic than the tics. It is usually best to begin with an effective treatment that is unlikely to cause any side effects.

Some available therapies include: Deep Brain Stimulation (DBS), Medications/ Pharmacology, Behavior Modification (Comprehensive Behavioral Intervention for Tics or CBIT), Speech Therapies

(TSA, 2019)

PROGNOSIS

Although TS can be a chronic condition with symptoms lasting a lifetime, most people with the condition experience their worst symptoms in their early teens, with improvement occurring in the late teens and continuing into adulthood. As a result, some individuals may actually become symptom free or no longer need medication for tic suppression.

(NINDS, 2019)

EDUCATIONAL IMPLICATIONS

The following are suggestions for dealing effectively with TS symptoms in the classroom setting:

Accommodations for Attention Problems

Some movements and noises can be annoying or disruptive to the class. Please remember that they are occurring involuntarily, and do not react with anger or annoyance! This requires patience, but reprimanding a student with TS student is like disciplining a student with cerebral palsy for being clumsy. If the teacher is not tolerant, others in the class may feel free to ridicule the child with TS.

If some aspect of the child's tics affects the privacy or safety of others (e.g., touching others), it is important to find ways to work around the problem, but acceptance of the child is critical even when the behaviors are unacceptable.

Accommodations for Writing Problems

Even very bright children with TS who have no trouble grasping concepts may be unable to finish written work because of visual-motor impairments. Sometimes it appears as though the student is lazy or avoiding work, but in reality the effort to record the work on paper may be overwhelming. A number of accommodations can be made to help children with writing difficulties succeed in the classroom:

Accommodations for Language Problems

Children with TS may repeat their own words or those of someone else. This may sound like stuttering but it actually involves the utterance or words or whole phrases. Other students may exploit this problem by whispering inappropriate things so that the child with TS will involuntarily repeat them and get into trouble. Be alert to this provocation. This urge to repeat can be seen in reading and writing activities. Students may be unable to complete work because they "get stuck" rereading or rewriting words or phrases over and over. This is called "looping." The following can be helpful:
