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.
Treatment of Tourette syndrome
There is increasing evidence supporting the use of HRT in the treatment of tics; a 2013 systematic review (Dutta, Cavanna) found evidence that HRT reduced tic severity in children and adults, but also identified methodological limitations in all studies, and said that more specialists need to be better trained to administer HRT so that better large-scale studies can be conducted.
