Which term is defined as a mood disorder and is listed in the material?

• A. Mood Disorder/Bi-Polar
• B. Schizophrenia
• C. Delusional
• D. Psychosis

Answer: (A)

Mood disorders involve disturbances in a person’s emotional state, such as prolonged sadness or alternating periods of elevated mood. Bipolar disorder, also called bipolar affective disorder, is a classic example of a mood disorder because it centers on mood episodes—manic or hypomanic states and depressive states. In the material, this term is listed under mood disorders, so it is the correct choice.

Schizophrenia is primarily a thought and perception disorder, with psychotic features, rather than a mood disorder. Delusional refers to fixed false beliefs that aren’t aligned with reality, which is a symptom or pattern rather than a mood category. Psychosis is a symptom cluster that can appear in multiple conditions, including mood and non-mood disorders, but it isn’t itself a mood disorder.
