Psychosis after acute alteration of thyroid status

Abstract

SYNOPSIS A case of acute schizophrenic psychosis developing during the treatment of hyper-thyroidism with carbimazole is described. The patient was clinically and biochemically euthyroid at the time the psychosis developed. It is suggested that an acute alteration in thyroid status, without necessarily producing hyper- or hypothyroidism, may be sufficient to induce a psychotic reaction.
