Hyperprolactinaemia in early psychosis-not only due to antipsychotics

Hyperprolactinaemia is often found in patients with schizophrenia and usually considered a consequence of antipsychotics. Prolactin levels were measured in 43 At-Risk Mental State individuals (ARMS) and 26 patients with First Episode Psychosis (FEP). Hyperprolactinaemia was found in 25.6% of ARMS and 462% of FEP Within 60 antipsychotic-naive ARMS and FEP, hyperprolactinaemia was found in 26.7%.
