Georges Gilles de la Tourette described symptoms of Tourette's syndrome.
 There are no specific medical or screening tests that can be used to diagnose Tourette's; the diagnosis is usually made based on observation of the individual's symptoms and family history, and after ruling out secondary causes of tic disorders (tourettism)
Tourette's was once regarded as a rare and bizarre syndrome and has popularly been associated with coprolalia (the utterance of obscene words or socially inappropriate and derogatory remarks)
