Introduction:
Tourette’s syndrome (TS) is a chronic developmental neuropsychiatric disorder with an onset in early childhood, affected by both genetic and environmental factors. TS is characterized by multiple complex motor and vocal tics, in addition to some other psychological disorder such as attention deficit hyperactivity disorder (ADHD) and obsessive–compulsive disorder (OCD). The exact pathophysiology of TS is unclear but recent studies suggest that there may be a defect in the Cortico-Striato-Thalamo-Cortical (CSTC) circuit. Besides self-limited cases, some of TS patients with mild symptoms may need conventional treatments such as psycho-behavioral therapy, educational therapy and pharmacotherapy while refractory cases are potential candidates for deep brain stimulation (DBS) procedure which leads to an improvement in both tic component and other comorbidities of TS, but with different extents [1]. Herein we report a patient with TS which his OCD improved after DBS without his tic to be improved.
