Tourette Syndrome, according to the National Institute of Neurological Disorders and Stroke (NINDS), is “…a neurological disorder characterized by repetitive, stereotyped, involuntary movements and vocalizations called tics. The disorder is named for Dr. Georges Gilles de la Tourette, the pioneering French neurologist who in 1885 first described the condition in an 86-year-old French noblewoman.”

From the NINDS website:

  • The early symptoms of TS are typically noticed first in childhood, with the average onset between the ages of 3 and 9 years.
  • TS occurs in people from all ethnic groups.
  • Males are affected about three to four times more often than females.
  • It is estimated that 200,000 Americans have the most severe form of TS, and as many as one in 100 exhibit milder and less complex symptoms such as chronic motor or vocal tics.
  • Although TS can be a chronic condition with symptoms lasting a lifetime, most people with the condition experience their worst tic symptoms in their early teens, with improvement occurring in the late teens and continuing into adulthood.
  • Coprolalia is only present in a small number (10 to 15 percent) of individuals with TS.
  • TS is a diagnosis that doctors make after verifying that the patient has had both motor and vocal tics for at least 1 year.  There are no blood, laboratory, or imaging tests needed for diagnosis.

From the website of the Centers for Disease Control (CDC)  website:

A Centers for Disease Control and Prevention (CDC) study conducted in 2011 found that 1 of every 360 children 6 through 17 years of age and living in the United States have been diagnosed with TS based on parent report; however,
  • 2014 reportings coordinated by the CDC and the National Tourette Syndrome Association state that it is estimated that 1 in 100 school-aged children in the United States is living with Tourette Syndrome or another Tic Disorder, which puts the prevalence at approximately 3,000,000 people nationwide.
  • Among children with TS, 37% have been reported as having moderate or severe forms of the condition.
