Vocal hyperacusis is a pediatric tic disorder with the scientific name of Tourette’s syndrome. It is a type of psychoneurological disorder that occurs in adolescence or childhood. It is associated with excessive dopamine transmission and reduced levels of homovanillic acid. The child starts with frequent blinking, pouting, mouth opening and tongue sticking. As the disease progresses, the twitching movements are not limited to the face, but may include head shaking, throat vocalization, self-talk, and shoulder shrugging. The disease is often fluctuating, sometimes mild and sometimes severe, sometimes relieving on its own, mostly when fatigue and lack of sleep. The treatment of the disease is mainly comprehensive medication, specifically including mood-regulating drugs such as sulpiride, risperidone, haloperidol, colistin, sodium valproate, clonazepam, dobutamine and other drugs.
