Tourette syndrome (also called Tourette's syndrome, Tourette's disorder, Gilles de la Tourette syndrome, GTS or, more commonly, simply Tourette's or TS) is an inherited neuropsychiatric disorder with onset in childhood, characterized by multiple physical (motor) tics and at least one vocal (phonic) tic. These tics characteristically wax and wane, can be suppressed temporarily, and are preceded by a premonitory urge. Tourette's is defined as part of a spectrum of tic disorders, which includes transient and chronic tics.

Tourette's was once considered a rare and bizarre syndrome, most often associated with the exclamation of obscene words or socially inappropriate and derogatory remarks (coprolalia), but this symptom is present in only a small minority of people with Tourette's. Tourette's is no longer considered a rare condition, but it is not always correctly identified because most cases are mild and the severity of tics decreases for most children as they pass through adolescence. Between .4% and 3.8% of children ages 5 to 18 may have Tourette's; the prevalence of transient and chronic tics in school-age children is higher, with the more common tics of eye blinking, coughing, throat clearing, sniffing, and facial movements. Extreme Tourette's in adulthood is a rarity, and Tourette's does not adversely affect intelligence or life expectancy.

Robert Peter "Robbie" Williams (born 13 February 1974) is an English singer-songwriter, vocal coach and occasional actor. He is a member of the pop group Take That.

Williams rose to fame in the band's first run in the early- to mid-1990s. After many disagreements with the management and certain group members, Williams left the group in 1995 to launch his solo career. On 15 July 2010, it was announced he had rejoined Take That and that the group intended to release a new album in November 2010 which became the second fastest-selling album of all-time in UK chart history and the fastest-selling record of the century.

Williams has sold over 70 million records worldwide, which ranks him among the best-selling music artists worldwide. He is the best-selling British solo artist in the United Kingdom and the best selling non-Latino artist in Latin America. Six of his albums are among the top 100 biggest-selling albums in the United Kingdom. He has also been honoured with seventeen BRIT Awards—more than any other artist—and seven ECHO Awards. In 2004, he was inducted into the UK Music Hall of Fame after being voted as the "Greatest Artist of the 1990s."
