Fast Five Quiz: Schizophrenia Presentation and Diagnosis

OC symptoms, such as the need to check, count, or repeat certain activities, are present in a number of patients with schizophrenia. The association between OC symptoms and schizophrenia is unclear; however, these symptoms are known to occur as an adverse effect of certain antipsychotic medications.

Although patients with schizophrenia may exhibit some OC symptoms, those exhibited by patients with schizophrenia are a completely separate diagnosis from obsessive-compulsive disorder (OCD). The OC symptoms of patients with schizophrenia occur in response to delusions and hallucinations, which these patients believe to be true, whereas patients with OCD doubt the truth regarding the content of their symptoms.

Many patients with schizophrenia report symptoms of depression and anxiety, but it remains unclear whether these symptoms are independent of schizophrenia, a response to schizophrenia, or a side effect of treatment.

Although some patients with schizophrenia may become violent, the majority of patients with schizophrenia are nonviolent.
