Major depressive disorder with psychotic features

Major depressive disorder with psychotic features is a serious mental health condition that affects the brain and how a person thinks, feels, and behaves. It combines symptoms of major depression, such as persistent sadness and loss of interest, with psychotic symptoms like hallucinations or delusions. These psychotic symptoms often relate to the depressive themes, such as feelings of guilt or worthlessness. This condition can severely impact daily functioning, relationships, and overall well-being. It requires careful diagnosis because the presence of psychosis changes the treatment approach and prognosis.

Major depressive disorder with psychotic features is a subtype of major depressive disorder characterized by the presence of psychotic symptoms—including delusions and/or hallucinations—that occur exclusively during depressive episodes. The core pathology involves dysregulation of monoamine neurotransmitters and altered brain circuits related to mood and perception. Psychotic symptoms are typically mood-congruent, reflecting themes of worthlessness or guilt. This disorder is clinically significant due to its association with increased severity, higher risk of suicide, and poorer response to standard antidepressant monotherapy. Diagnosis requires careful differentiation from primary psychotic disorders and bipolar disorder with psychotic features. Treatment often involves a combination of antidepressants and antipsychotics or electroconvulsive therapy.
