Published 04/27/2022

According to the Schizophrenia and Related Disorders Alliance of America or SARDAA, schizophrenia impacts about 1.1% of the population worldwide. In the United States alone, 3.5 million people are living with schizophrenia. The prevalence of schizoaffective disorder, however, is only 0.3%. Schizoaffective disorder is similar to schizophrenia in some regards, but it is not the same. So, what is the difference? This article will talk about both disorders and how to differentiate the two, and how to get support for schizophrenia spectrum and other psychotic disorders, including schizophrenia and schizoaffective disorder.

What Is Schizoaffective Disorder?

Schizoaffective disorder, in short, is a disorder that pairs the symptoms of schizophrenia with the symptoms of a mood disorder. The APA dictionary of psychology defines the schizoaffective disorder as "an uninterrupted illness featuring at some time a major depressive episode, manic episode, or mixed episode concurrently with characteristic symptoms of schizophrenia (e.g., delusions, hallucinations, disorganized speech, catatonic behavior) and, in the same period, delusions or hallucinations for at least 2 weeks in the absence of prominent mood symptoms. DSM–5 identifies the mood episodes only as either major depressive or manic and emphasizes that mood disturbances must be present for a majority of the time." To be diagnosed with schizoaffective disorder, you must meet the criteria for a schizoaffective disorder listed in the most recent version of the DSM, which is currently the DSM-5.

What Is Schizophrenia?

Schizophrenia is a mental health disorder characterized by hallucinations, delusions, and other symptoms, such as disorganized thoughts and speech. There's no cure for schizophrenia, but with treatment, symptoms can improve dramatically, and a person with schizophrenia can live a full, happy life with symptom management. Symptoms of schizophrenia may include:

  • Hallucinations, which often include seeing things that aren't there or hearing voices that are not there
  • Delusions (firmly held false beliefs)
  • Social isolation or withdrawal from others
  • Disorganized thoughts or unusually disorganized speech, such as incoherent or frenzied speech. Sometimes, incoherent, choppy speech with random, seemingly unrelated words or phrases is seen in schizophrenia. This is sometimes referred to as "word salad."
  • "Negative symptoms," such as a flat affect or lack of emotion in one's facial expressions or speech, neglected personal hygiene, and a lessened ability or inability to engage in normal daily activities. In this context, negative means "taking away." Click hereto read the American Psychological Association's definition of negative symptoms
  • Withdrawal from activities one would generally enjoy, or lack of interest in those activities
  • Abnormal posture or movements
  • A low or depressed mood
  • Trouble sleeping or insomnia
  • Trouble concentrating or focusing
  • Paranoia
  • Irritability or anger

If you notice symptoms of schizophrenia in yourself, it's important to immediately reach out to a medical or mental health professional.

Schizoaffective Disorder Vs. Schizophrenia

If you compare symptoms of schizophrenia with the symptoms of schizoaffective disorder, you will see that the signs and symptoms of schizophrenia are all present, but that schizoaffective disorder includes additional symptoms that relate to mood disorders. This is because schizoaffective disorder, when put simply, is more or less schizophrenia paired with the symptoms of a mood disorder. In other words, schizoaffective disorder is a disorder that combines the symptoms of schizophrenia with the experience of a mood disorder. Someone with schizoaffective disorder will experience both schizophrenia symptoms and mood disorder related symptoms.
