All are affective disorders EXCEPT:
Appeared in: HP CHO -9 October 2022
Explanation
- Schizophrenia is fundamentally a psychotic disorder, not an affective disorder.
- Its primary features are disturbances in thought processes, perception (like hallucinations and delusions), and behavior, rather than a primary disturbance of mood.
- While individuals with schizophrenia can experience mood symptoms (like flat affect or depression), the core illness is defined by psychosis.
- The differential diagnosis between schizophrenia and mood disorders with psychotic features is critical for determining the correct long-term treatment, such as mood stabilizers for bipolar disorder versus antipsychotics for schizophrenia (SRC_3211).
Why Other Options Were Wrong
- Option A: Depression is a primary example of an affective disorder, characterized by a persistent low mood and loss of pleasure (anhedonia).
- Option C: Grief is a normal affective (emotional) response to a significant loss. It is a state of affect, and while not a disorder in its uncomplicated form, it is fundamentally related to mood and emotion.
- Option D: Euphoria is an elevated mood state. While not a disorder itself, it is a hallmark symptom of mania, which is a key component of bipolar affective disorder.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Classification of mental health disorders, specifically the distinction between affective (mood) disorders and psychotic disorders as background academic context rather than a clinical decision trigger.
- Differentiating between affective and psychotic disorders is crucial for safe and effective nursing care, as treatment and safety priorities differ significantly.
- A patient with depression requires vigilant assessment for suicide risk. A patient with schizophrenia requires assessment for command hallucinations that may lead to harm to self or others. A patient in a manic state requires monitoring for risky behaviors and physical exhaustion.
- What if? If a patient with bipolar disorder is misdiagnosed with schizophrenia and treated only with a traditional antipsychotic, they may not receive the necessary mood-stabilizing medication, leading to poor outcomes, continued mood cycling, and increased risk of suicide (SRC_3211).
How to Approach the Question
- First, identify the key term in the question: 'affective disorders'. Recall or define this term as 'mood disorders'.

- Evaluate each option: 'Depression' is a mood disorder. 'Grief' is a mood/emotional state. 'Euphoria' is a mood state seen in mania (a mood disorder).
- Consider 'Schizophrenia'. Recall that this is primarily a thought disorder (psychotic disorder), characterized by delusions and hallucinations.
- Conclude that Schizophrenia is the outlier and therefore the correct answer.
