« Back to Glossary Index

Schizoaffective disorder is a complex mental health condition characterized by a combination of symptoms from both schizophrenia and mood disorders such as depression or bipolar disorder. Individuals with this disorder experience episodes of psychosis, including hallucinations and delusions, alongside significant mood disturbances, either depressive or manic. The exact cause of schizoaffective disorder remains unclear, but it is believed to involve genetic, biological, and environmental factors. Diagnosis is challenging due to the overlapping symptoms with other mental health conditions, requiring comprehensive assessment by healthcare professionals. Treatment typically involves a combination of medications—such as antipsychotics, mood stabilizers, and antidepressants—and psychotherapy, aiming to manage symptoms and improve quality of life​ (Mayo Clinic) (NAMI) (Yale Medicine) (Cleveland Clinic).

What is Schizoaffective Disorder?

Schizoaffective disorder is a complex psychiatric condition characterized by the presence of both schizophrenia symptoms, such as hallucinations and delusions, and mood disorder symptoms, such as mania or depression. According to the DSM-5 criteria, to be diagnosed with schizoaffective disorder, an individual must experience psychotic symptoms for at least two weeks in the absence of mood disorder symptoms, while mood symptoms must be present for the majority of the illness duration. This disorder is challenging to diagnose due to its overlapping features with schizophrenia and mood disorders​ (Mayo Clinic)​​ (Yale Medicine)​.

Research indicates that schizoaffective disorder may result from a combination of genetic, biochemical, and environmental factors. Abnormalities in brain structure and neurotransmitter function play a significant role, and stressors such as traumatic events or substance abuse can trigger the onset or exacerbation of symptoms. Treatment usually involves a comprehensive approach, including antipsychotic medications, mood stabilizers, and psychotherapy, tailored to manage both psychotic and mood-related symptoms effectively​ (Mayo Clinic)​​ (Yale Medicine)​​ (Cleveland Clinic) (1)​.
