Tourette's syndrome (TS) is a disease characterized by multiple motor and vocal tics as well as behavioral abnormalities. The anatomic substrates of this syndrome are not defined. We report a 48-year-old man with TS in whom motor tics disappeared after the onset of a midbrain syndrome related to thiamine deficiency (Wernicke's encephalopathy). MRI study showed a lesion in the dorsal area of the midbrain. This case suggests that loops located in the midbrain tegmentum may influence the presence of motor tics in patients with TS.

Abstract
Tourette's syndrome (TS) is a disease characterized by multiple motor and vocal tics as well as behavioral abnormalities. The anatomic substrates of this syndrome are not defined. We report a 48-year-old man with TS in whom motor tics disappeared after the onset of a midbrain syndrome related to thiamine deficiency (Wernicke's encephalopathy). MRI study showed a lesion in the dorsal area of the midbrain. This case suggests that loops located in the midbrain tegmentum may influence the presence of motor tics in patients with TS.
