Treatment of Tourette syndrome
There is no cure for Tourette's and no medication which works universally for all individuals without significant adverse effects; knowledge and understanding are the best treatments available for tics. Management of the symptoms of Tourette's may include pharmacological, behavioral and psychological therapies. While pharmacological treatment is reserved for more severe symptoms, other types of treatments may help avoid or improve symptoms of depression or social isolation, and improve supportive family functioning. Educating the patient, family, and surrounding community (school, church, friends, etc.) is a key part of treatment.
Medical cannabis research
Cannabinoid medication might be useful in the treatment of the symptoms in patients with TS, but the 2009 review found that the two relevant studies of cannibinoids in treating tics had attrition bias, and that there was "not enough evidence to support the use of cannabinoids in treating tics and obsessive compulsive behaviour in people with Tourette's syndrome".
