Twentieth Century
The possibility that movement disorders, including Tourette syndrome, might have an organic origin was raised when an encephalitis epidemic from 1918–1926 led to a subsequent epidemic of tic disorders. The psychoanalytic theory was so dominant that it was claimed that an organic component alone would not be sufficient to produce Tourette syndrome. At the time, psychiatrists believed patients with tics must also be suffering from unresolved psychological disturbances or psychosexual conflicts, and psychiatric intervention was the preferred method of treatment. Patients and their families were told that their own psychological maladjustments were to blame for their symptoms, adding to the burden carried by the patients and their families. Until the early 1970s, psychoanalysis was the preferred intervention for Tourette syndrome.
During the 1960s and 1970s, as the beneficial effects of haloperidol (Haldol) on tics became known, the psychoanalytic approach to Tourette syndrome was questioned. The first description of haloperidol in the treatment of Tourette's was published by Seignot in 1961. The turning point came in 1965, when Arthur K. Shapiro—described as "the father of modern tic disorder research"—treated a Tourette’s patient with haloperidol. Dr. Shapiro and his wife, Elaine Shapiro (PhD), reported the treatment in a 1968 article, and severely criticized the psychoanalytic approach.
The Shapiros, working with the patient families who founded the Tourette Syndrome Association (TSA) in 1972, advanced the argument that Tourette's is a neurological, rather than psychological, disorder, and worked to persuade the media to promote information about Tourette's. The U.S. National Institutes of Health (NIH) turned down a 1972 grant proposal from the TSA because "the reviewers believed there were probably no more than 100 cases of TS in the entire nation", and a 1973 registry reported only 485 cases worldwide. Subsequent articles on Tourette's in Good Housekeeping, The New York Times and Ann Landers produced an "enormous response, proving that there were many undiagnosed cases of TS across the United States".
Since the 1990s, a more neutral view of Tourette's has emerged, in which biological vulnerability and adverse environmental events are seen to interact. In 2000, the American Psychiatric Association published the DSM-IV-TR, revising the text of DSM-IV to no longer require that symptoms of tic disorders cause distress or impair functioning. However, multiple studies published since 2000 have consistently demonstrated that the prevalence is much higher than previously thought. The emerging consensus is that 1–10 children per 1,000 have Tourette's, with several studies supporting a tighter range of 6–8 children per 1,000. Using year 2000 census data, a prevalence range of 1–10 per 1,000 yields an estimate of 53,000–530,000 school-age children with Tourette's in the US and a prevalence range of 6–10 per 1,000 means that 64,000–106,000 children aged 5–18 years may have Tourette's in the UK. Most of these children are undiagnosed and have mild symptoms without distress or impairment.

Famous quotes related to twentieth century:
“Predatory capitalism created a complex industrial system and an advanced technology; it permitted a considerable extension of democratic practice and fostered certain liberal values, but within limits that are now being pressed and must be overcome. It is not a fit system for the mid- twentieth century.”
—Noam Chomsky (b. 1928)
“A writer is in danger of allowing his talent to dull who lets more than a year go past without finding himself in his rightful place of composition, the small single unluxurious ‘retreat’ of the twentieth century, the hotel bedroom.”
—Cyril Connolly (1903–1974)
“Advertising is the greatest art form of the twentieth century.”
—Marshall McLuhan (1911–1980)
“The nineteenth century planted the words which the twentieth ripened into the atrocities of Stalin and Hitler. There is hardly an atrocity committed in the twentieth century that was not foreshadowed or even advocated by some noble man of words in the nineteenth.”
—Eric Hoffer (1902–1983)
“In the twentieth century one of the most personal relationships to have developed is that of the person and the state.... It’s become a fact of life that governments have become very intimate with people, most always to their detriment.”
