[Acute Schizophrenic Disorder in a Patient with Hashimoto's Thyroiditis].

While for some diseases with hyperthyreosis psychotic developments are well known, for a rare autoimmune thyroiditis, Hashimoto's thyroiditis, only one case of development of psychotic symptoms is known. In this case-study we present a 42-year-old white female who was admitted to hospital showing symptoms of acute psychosis. The results of the laboratory examinations showed the constellation of beginning Hashimoto's thyroiditis in hyperthyreotic state with high level of antithyroid peroxidase antibodies and comparatively low level of anti-TSH receptor antibodies. The patient recovered well in 4-weeks time under therapy with neuroleptics and benzodiazepines.
