Schizoaffective disorder refers to a condition in which, during the same episode, symptoms simultaneously meet diagnostic criteria for both schizophrenia and mood disorders. Its clinical manifestations are categorized into manic type, depressive type, and mixed type. Patients may exhibit psychotic symptoms such as hallucinations and delusions, along with mood disturbances like elevated or depressed mood. For example, a patient might firmly believe they are being followed or monitored while also showing emotional excitement leading to unrealistic planning, or experience feelings of guilt and self-blame alongside delusions of reference.

The disorder was first proposed by psychiatrists in the 1930s to describe acute-onset psychiatric conditions with prominent affective features. Research indicates that it has stable internal consistency. Diagnosis requires both psychotic and mood symptoms to be clearly present, with psychotic symptoms persisting for at least two weeks, and the onset and remission times of both symptom types being closely aligned.

Schizoaffective disorder lies between schizophrenia and bipolar disorder in terms of clinical characteristics. Its diagnosis and treatment have unique aspects, requiring professional assessment to distinguish primary from secondary symptoms and to avoid confusion with other psychiatric disorders.
