Tourette’s Syndrome (TS) is characterized by repeated, involuntary
movements and uncontrollable vocal sounds, known as tics. Affecting
approximately 100,000 Americans in its full-blown form, TS generally
emerges during childhood or early adolescence.
Although the basic cause of TS is unknown, current research suggests
there is a genetic abnormality affecting certain neurotransmitters in the
brain, and that varying environmental factors, possibly including
infections, modifies the clinical expression of the disorder. Symptoms of
TS are seen in association with some other neurological disorders,
particularly OCD. Researchers are investigating the neurological
similarities between OCD and TS to determine whether a genetic
relationship exists.
In most cases, Tourette’s Syndrome is not disabling, symptoms don’t
impair patients, development proceeds normally, and there is no need for
treatment. However, some effective medications are available in the rare
instances when symptoms interfere with functioning. Children with TS can
generally function well at home and in the regular classroom. If they have
an accompanying learning disability or other disorder, such as ADHD or OCD, they may require tutoring, special classes, psychotherapy, or
medication.
