Treatment of Tourette syndrome
Habit reversal training (HRT), massed negative practice, biofeedback, relaxation, hypnosis and other behavioral approaches are proposed as alternative treatments of tics, but few have been well assessed. Relaxation techniques, such as exercise, yoga or meditation, may be useful in relieving stress that may aggravate tics, but the majority of behavioral interventions (such as relaxation training and biofeedback, with the exception of habit reversal) have not been systematically evaluated and are not proven therapies for Tourette's.
History of Tourette syndrome
Little progress was made over the next century in explaining or treating tics. With limited clinical experience, involving typically one or two patients, authors advanced different ideas, including brain lesions similar to those resulting from rheumatic chorea or encephalitis lethargica as a cause of tics, faulty mechanisms of normal habit formation, and treatment with Freudian psychoanalysis. The psychogenic view prevailed well into the 20th century.
