Tourette disorder features multiple motor tics and at least one vocal tic that begin in childhood and tend to wax and wane over time. In some children, tic symptoms can be linked to PANDAS, a condition thought to involve autoimmune reactions after streptococcal infections, which can trigger abrupt changes in tic severity and related symptoms. Treatments for Tourette often combine behavioral interventions with medication or, in severe cases, surgical approaches. Clonidine and guanfacine are alpha-2 adrenergic agonists that can help reduce tic symptoms and associated hyperactivity. Haloperidol, a dopamine antagonist, has been used to dampen tics when needed. Deep brain stimulation is considered for highly refractory Tourette syndrome. Other conditions such as stereotypy (repetitive movements seen in various developmental contexts), spasmodic torticollis (cervical dystonia), or hemifacial spasm (facial nerve irritation) do not share this specific autoimmune-linked tic profile or the same broad treatment approach.
