What is the name of the disorder characterized by schizophrenia symptoms plus a mood disorder?

The disorder characterized by symptoms of schizophrenia alongside a mood disorder is known as schizoaffective disorder. This condition is defined by the presence of a major mood episode (either major depressive or manic) occurring concurrently with symptoms that meet the criteria for schizophrenia, such as delusions, hallucinations, disorganized thinking, or negative symptoms.

In schizoaffective disorder, the mood symptoms are prominent and must stand out in the patient's presentation, and patients can experience significant impairment in social or occupational functioning as a result. A key feature that distinguishes schizoaffective disorder from other psychotic disorders is that mood symptoms are present for a substantial portion of the illness, rather than merely occurring for a short duration in isolation.

In terms of other disorders listed, delusional disorder involves the presence of one or more persistent delusions without the notable mood components that characterize schizoaffective disorder. Brief psychotic disorder presents with transient psychotic symptoms that last for more than a day but less than a month, often following a stressful event, without a lasting mood disorder. Schizophreniform disorder features schizophrenia-like symptoms but either lacks the mood disorder component or does not meet the full criteria for schizophrenia in terms of duration and functional impact.
