title: Tic disorder probably associated with steroid responsive encephalopathy with autoimmune thyroiditis (SREAT).
abstract: Steroid responsive encephalopathy with autoimmune thyroiditis (SREAT), a rare disorder in individuals of all age groups, including children, is characterized by high titers of anti-thyroid peroxidase antibodies. The present report concerns a previously healthy 12-y-old boy who presented with motor tics. The patient underwent an extensive work-up to identify the underlying etiologies and risk factors predisposing him to tic disorder. Based on the clinical and laboratory results, a diagnosis of SREAT was made. Although some studies have reported associated behavioral and cognitive changes, myoclonus, seizures, pyramidal tract dysfunction, psychosis, and coma. The authors describe a case of tic disorder, probably due to SREAT, as well as its course of treatment.
