What mental health conditions are included in the schizophrenia spectrum?

Mark Moronell, MD
Cardiology (Cardiovascular Disease)
Some of the schizophrenia spectrum disorders include:

• Schizophrenia
• Childhood schizophrenia (also called early onset schizophrenia)
• Schizoaffective disorder
• Schizoid personality disorder
• Schizotypal personality disorder

These conditions are grouped together in the schizophrenia spectrum because they share many of the same features. For instance, schizoaffective disorder shares many of the same qualities as schizophrenia, except that people with schizoaffective disorder also experience severe mood symptoms, like depression or bipolar illness. The traditional diagnosis of schizophrenia excludes people who have mood disorders. Those with schizoid personality disorder and schizotypal personality disorder don't usually experience the psychotic symptoms observed in those with schizophrenia, but people with these conditions tend to isolate themselves. In addition, people with schizotypal personality disorder may display strange thoughts and actions, and may appear paranoid, like those with schizophrenia. Both of the schizophrenia spectrum personality disorders are more commonly found in people who have relatives diagnosed with schizophrenia.
