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.
Tourette syndrome
Findings since 1999 have advanced TS science in the areas of genetics, neuroimaging, neurophysiology, and neuropathology. Questions remain regarding how best to classify Tourette syndrome, and how closely Tourette's is related to other movement disorders or psychiatric disorders. Good epidemiologic data is still lacking, and available treatments are not risk free and not always well tolerated. High-profile media coverage focuses on treatments that do not have established safety or efficacy, such as deep brain stimulation, and alternative therapies involving unstudied efficacy and side effects are pursued by many parents.
