  Schizoaffective disorder is one of the most misdiagnosed psychiatric disorders in clinical practice. […] The term schizoaffective disorder first appeared as a subtype of schizophrenia in the first edition of the DSM. It eventually became its own diagnosis despite a lack of evidence for unique differences in etiology or pathophysiology. Therefore, there have been no conclusive studies on the disorder’s etiology. However, investigating the potential causes of mood disorders and schizophrenia as individual disorders allows for further discussion. […] Some studies show that as high as 50% of people with schizophrenia also have comorbid depression. The pathogenesis of both mood disorders and schizophrenia is multifactorial and covers a range of risk factors, including genetics, social factors, trauma, and stress. Among people with schizophrenia, there is a possible increased risk for first-degree relatives for schizoaffective disorder and vice-versa; there may be increased risk among individuals for schizoaffective disorder who have a first-degree relative with bipolar disorder, schizophrenia or schizoaffective disorder.

[…] The exact cause of schizoaffective disorder has not yet been determined, but various risk factors are known: Genetics: Individuals may inherit the tendency to develop features associated with schizoaffective disorder. Brain disorder or injury: Patients with schizophrenia and mood disorders may have problems with neuronal circuits in the brain that manage mood and thinking. Environmental factors: Viral infections or highly stressful situations could play a role in the development of schizoaffective disorder in at-risk individuals. Psychoactive or psychotropic drugs: Taking mind-altering drugs (i.e., those that affect emotions, thoughts, and behavior) can lead to schizoaffective disorder.

  The exact cause of schizoaffective disorder isn’t clear, but it may be a mix of genetics and environmental factors. […] People are more likely to develop schizoaffective bipolar disorder if they have immediate family members, such as parents or siblings, with depression, bipolar disorder, schizophrenia, or other mental health conditions. […] Previous trauma or post traumatic stress disorder is also common among people with severe mental illnesses, such as schizoaffective bipolar disorder. […] While both genetics and trauma may contribute to developing schizoaffective bipolar disorder, „these in themselves are not indicators that someone will develop this diagnosis,” says Samuel.

  Schizoaffective disorder is one of the most misdiagnosed psychiatric disorders in clinical practice. […] The term schizoaffective disorder first appeared as a subtype of schizophrenia in the first edition of the DSM. It eventually became its own diagnosis despite a lack of evidence for unique differences in etiology or pathophysiology. Therefore, there have been no conclusive studies on the disorder’s etiology. However, investigating the potential causes of mood disorders and schizophrenia as individual disorders allows for further discussion. […] Some studies show that as high as 50% of people with schizophrenia also have comorbid depression. The pathogenesis of both mood disorders and schizophrenia is multifactorial and covers a range of risk factors, including genetics, social factors, trauma, and stress. Among people with schizophrenia, there is a possible increased risk for first-degree relatives for schizoaffective disorder and vice-versa; there may be increased risk among individuals for schizoaffective disorder who have a first-degree relative with bipolar disorder, schizophrenia or schizoaffective disorder.

  Schizoaffective disorder is a mental health condition that includes features of both schizophrenia and a mood disorder such as bipolar disorder or depression. […] Very little is known for certain about the genetics of schizoaffective disorder. Studies suggest that variations in many genes, each with a small effect, combine to increase the risk of developing the condition. […] The inheritance pattern of schizoaffective disorder is unclear. Overall, the risk of developing this condition is greater for first-degree relatives of affected individuals (such as siblings or children) as compared to the general public. Many individuals with schizoaffective disorder also have relatives with depression, bipolar disorder, schizophrenia, or other mental health conditions. These disorders may run in families in part because they share some genetic risk factors with schizoaffective disorder.

  Genetics (researched in the field of genomics); problems with neural circuits; chronic early, and chronic or short-term current environmental stress appear to be important causal factors. […] No single isolated organic cause has been found, but extensive evidence exists for abnormalities in the metabolism of tetrahydrobiopterin (BH4), dopamine, and glutamic acid in people with schizophrenia, psychotic mood disorders, and schizoaffective disorder. […] A combination of genetic and environmental factors are believed to play a role in the development of schizoaffective disorder. […] Genetic studies do not support the view that schizophrenia, psychotic mood disorders and schizoaffective disorder are distinct etiological entities, but rather the evidence suggests the existence of common inherited vulnerability that increases the risks for all these syndromes.
