Abstract

The association between disorders of thyroid function and psychiatric symptoms is well established. Generally, hypo-thyroidism is recognized as being able to induce psychotic symptoms. However, psychotic symptoms without affective and cognitive disturbances are rare in hyperthyroidism. We presented a patient with Graves’ disease who suffered from delusions and hallucinations without affective and cognitive disturbances following abrupt normalization of thyroid function. Furthermore, the patient was clinically and biochemically euthyroid when the psychotic symptoms developed. There was resolution of psychotic symptoms in this case. It is suggested that the abrupt change of thyroxine may cause susceptible individuals to become transient psychotic state.
