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.
Olanzapine
Olanzapine has not been rigorously evaluated in generalized anxiety disorder, panic disorder, delusional parasitosis, or post-traumatic stress disorder. Olanzapine is no less effective than lithium or valproate and more effective than placebo in treating bipolar disorder. It has also been used for Tourette syndrome and stuttering.
