Dopamine-sensitive abnormality in Tourette syndrome

For many years, researchers have thought that people with Tourette
syndrome, a neurological disorder characterized by abrupt movements
called tics, have sensitivity to dopamine levels in the brain. In a
study, Washington University School of Medicine researchers found
abnormal brain activity in people with Tourette syndrome during
memory tasks. When given levodopa, a form of dopamine used to treat
Parkinson's disease, the brain activity normalized. The researchers
have begun a study of whether levodopa can help control the tics in
Tourette syndrome.
