Black Patients With Severe Depression More Likely to Be Misdiagnosed With Schizophrenia

Black patients with severe depression are more likely than their white counterparts to be misdiagnosed with schizophrenia, according to a new study published in the journal Psychiatric Services.

The findings suggest that clinicians put more emphasis on psychotic rather than depressive symptoms in African-Americans, which skews diagnoses toward schizophrenia even when these patients show similar depressive and manic symptoms as white patients.

For the study, researchers at Rutgers University looked at the medical records of 1,657 individuals (599 blacks and 1,058 non-Latino whites) from a community behavioral health clinic.

“By definition, schizophrenia is a diagnosis of exclusion: Clinicians must rule out other potential causes of symptoms, including mood disorders, before the diagnosis of schizophrenia is given,” said Dr. Michael Gara, a professor of psychiatry at Rutgers Robert Wood Johnson Medical School and a faculty member at Rutgers University Behavioral Health Care.

“However, there has been a tendency for clinicians to overemphasize the relevance of psychotic symptoms and overlook symptoms of major depression in African-Americans compared with other racial or ethnic groups. No studies show that African-Americans with schizophrenia are more likely to also have major depression.”

The research found that clinicians failed to effectively weigh mood symptoms when diagnosing schizophrenia among African-Americans, suggesting that racial bias, whether conscious or subconscious, is one factor in the diagnosis of schizophrenia in this population.

Other factors include genetics, poverty and discrimination, as well as symptoms caused by infections and malnutrition early in life.

“Individuals from a racial minority group also might feel hopelessness or mistrust when being assessed by someone from a racial majority group, which could affect how they act and how the clinician interprets symptoms,” Gara said.

The study suggests that clinicians put more emphasis on psychotic symptoms in black patients, which leans diagnoses toward schizophrenia even when these individuals exhibit similar depressive and manic symptoms as white patients.

“Inaccurate diagnosis can have serious consequences,” Gara said. “Mood disorder treatments differ from those for schizophrenia, and the prognosis for these conditions is typically more positive than for schizophrenia.”

“These patients who may have major depression with psychotic features or bipolar disorder and who are misdiagnosed with schizophrenia do not receive the optimal treatment, putting them at risk for the worsening of the underlying disease process or for suicide. Also, the side effects of medication taken for schizophrenia, such as diabetes and weight gain, can be serious.”

The research team recommended requiring screening for major depression when evaluating black patients for schizophrenia.

The study supports the extensive research conducted by co-author Dr. Stephen Strakowski of Dell Medical School on how overemphasis of psychotic symptoms in African-Americans can contribute to misdiagnosis of schizophrenia spectrum disorders.
