What percentage of individuals display depressive symptoms in schizophrenia?

• A. About three-quarters display depressive symptoms
• B. No depressive symptoms
• C. About half display depressive symptoms
• D. All patients display depressive symptoms

Answer: (C)

Depressive symptoms are a common companion to schizophrenia, meaning mood-related experiences often appear alongside psychotic features rather than being universal or absent. The best-supported figure is that about half of individuals with schizophrenia show depressive symptoms at some point in their illness. This mood component can vary from subthreshold symptoms to a full major depressive episode and may fluctuate with illness phase or treatment. It’s important to distinguish true depressive symptoms from negative symptoms of schizophrenia, such as avolition or flat affect, since they overlap but have different implications for treatment and risk, including suicide risk. So, roughly fifty percent is the most accurate general estimate.
