[Gilles de la Tourette Syndrome: Symptoms, Causes and Therapy]

Gilles de la Tourette syndrome is a chronic neuropsychiatric movement disease with combined motor tics and at least one vocal tic for a minimum period of 1 year. It typically begins in the childhood (under 18 years of age).Most of the patients with Tourette syndrome have comorbidities, which often impair their quality of life more than the tics themselves.There are reported abnormalities in the cortico-striato-thalamo-cortical regions as well as in the neurotransmission of dopamine and other neurotransmission systems. Genetic and non genetic factors are discussed.In each patient psychoeducation is the basis of treatment. Specific treatment is only needed in more severe tic disorders which cause evident psychosocial impairment.Behavior therapy should be tried before drug treatment. For very severely affected adults, deep brain stimulation is a further treatment option.
