[Hyperkinetic disorder--a new view? (Generalized resistance to thyroid hormone)].

A psychiatric disorder well known for more than fifty years in children and adolescents has changed several times its name. Mild child encephalopathy, minimal (mild) cerebral dysfunction, impaired attention, hyperkinetic disorder. The cause is not known, there is, however, evidence of familial disposition. Symptoms of this disorder were fully manifested in patients with generalized resistance to thyroid hormone. The disease is due to a genetic mutation of the beta-thyroid receptor and characterized by a reduced response of the pituitary and peripheral tissue to thyroid hormone. The authors refer to the work of authors, who discovered the association between the hyperkinetic disorder and generalized resistance to thyroid hormone.
