 In previous editions of the DSM, paranoid schizophrenia was differentiated by the presence of hallucinations and delusions involving the perception of persecution or grandiosity in one's beliefs about the world.With the removal of the subtypes of schizophrenia in the DSM-5, paranoid schizophrenia will no longer be used as a diagnostic category.If a person expresses symptoms of schizophrenia, including symptoms previously associated with paranoid schizophrenia, they will be diagnosed with schizophrenia and be treated accordingly.
