A comparison for thyroid functions and clinical features in deficit and non-deficit schizophrenia

A comparison for thyroid functions and clinical features in deficit and non-deficit schizophrenia SUMMARY Objective: The primary occurrence and persistence of negative symptoms observed in patients with schizophrenia is deficit syndrome. Although the association between thyroid hormones and schizophrenia symptoms has been reported, no studies have investigated thyroid function in patients with deficit schizophrenia (DS). This study aims to investigate the clinical features and thyroid function in DS patients by comparing them with patients with non-deficit schizophrenia (NDS) and a control group.
