What Is the Connection Between Schizophrenia and Depression?

Post-schizophrenic depression refers to the residual stage of schizophrenia or depression symptoms after psychosis, which accounts for 25% of cases. It is one of the main causes of suicide in patients with schizophrenia. The causes include depression caused by antipsychotic drugs, primary schizophrenia itself with depressive symptoms, and patients who maintain good personality after the disappearance of psychiatric symptoms due to their own schizophrenia.
