[Hyperthyroidism, psychiatric syndromes and cranial CT].

Acute hyperthyroidism is known to be a cause of psychopathologic and especially anxiety syndromes. A review of the literature will be given. Nonreversible psychopathologic changes in an euthyroid state after hyperthyroidism are also described. Correlations between T4-concentration and neuropsychologic and electroencephalographic findings were reported. CT findings of the brain are not mentioned. A case report should help to discuss nonreversible changes after hyperthyroidism and cranial CT findings.
