Study Details
Study Description
Brief Summary
The purpose of this pilot study is to evaluate the effects of Atomoxetine, a selective noradrenaline reuptake inhibitor, on impulsivity in patients with Tourette's syndrome.

Detailed Description
High impulsivity characterizes severe forms of Tourette's syndrome, in which motor and vocal tics are associated with various neuropsychiatric disorders as compulsive disorders, difficult to manage and impairing quality of life of patients and their family. Previous preclinical study and clinical studies in attention-deficit hyperactivity disorder and Parkinson's disease demonstrate that atomoxetine, a selective noradrenaline reuptake inhibitor, improves response inhibition in high impulsive individuals. However, there is no suffisant data in Tourette's syndrome. The purpose of this pilot study is to evaluate the effects of Atomoxetine on impulsivity in 10 to 35 years old patients with Tourette's syndrome.

Outcome Measures
Primary Outcome Measures
- Impulsive state [8 weeks]
The primary outcome is the variation of impulsive state (%) before and after chronic administration of atomoxetine, as measured with quantitative tool (CANTAB)
Secondary Outcome Measures
- Cognition, anxiety, depression, severity of tics and compulsive disorders Tolerance [8 weeks]
The secondary outcomes are the effects of Atomoxetine in cognition, anxiety, depression, severity of tics and compulsive disorders, as mesured with autoquestionnaries. The investigators also evaluate the tolerance of chronic administration of atomoxetine in patients with Tourette's syndrome.
