According to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, at least two of these symptoms must be present for a significant amount of time over a 1-month period for a patient to meet the criteria for a diagnosis of schizophrenia:  

  • Delusions

  • Hallucinations

  • Disorganized speech

  • Disorganized or catatonic behavior

  • Negative symptoms

In addition, at least one of the symptoms must be delusions, hallucinations, or disorganized speech. Moreover, symptoms of schizophrenia must be present for a substantial portion of time during a 1-month period, and the patient's level of functioning in one or more major areas of life (eg, work, interpersonal relationships, self-care) must be substantially below the level achieved prior to the onset of symptoms.

Negative symptoms or disorganized or catatonic behavior may be absent in patients with schizophrenia; such patients, however, still might meet the diagnostic criteria for schizophrenia. A patient would meet the criteria for a diagnosis of schizophrenia with the presence of at least two of those symptoms.
