Question

Quizplus · Accepted Answer

Dopamine dysfunction has been implicated in Tourette's syndrome, specifically an overactivity of dopamine in certain regions of the brain. This is supported by the fact that medication that reduces dopamine activity (such as antipsychotics) can help reduce tics in some individuals with Tourette's. Serotonin and acetylcholine have not been directly implicated in Tourette's.
