Explanation

Hypersomnia, or excessive sleeping, is the hallmark sleep disturbance of atypical depression, not melancholic depression.
Melancholic depression is classically associated with the opposite condition: insomnia, particularly waking up too early (terminal insomnia).
Therefore, hypersomnia is the sleep-related disturbance listed that would not be expected to occur as a primary feature of melancholic depression.

Option A: Terminal insomnia, or early morning awakening, is a classic and very common feature of melancholic depression.
Option C: Increased REM sleep (specifically, increased REM density and decreased REM latency) is a well-documented polysomnographic finding in major depression, including the melancholic subtype.
Option D: Obstructive sleep apnoea (OSA) is a distinct sleep-breathing disorder, not a core symptom of melancholic depression itself. While it can be a comorbidity, it is not a feature that 'occurs' as part of the depressive syndrome.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Differentiating sleep disturbances in subtypes of depression, specifically melancholic versus atypical depression as background academic context rather than a clinical decision trigger.
A nurse's detailed sleep assessment is crucial for differential diagnosis in mood disorders. Asking not just 'Do you have trouble sleeping?' but 'Do you have trouble falling asleep, staying asleep, or do you wake up too early?' can provide vital clues.
Recognizing the specific sleep pattern helps anticipate patient needs. A patient with terminal insomnia may need a quiet environment in the early morning, whereas a patient with hypersomnia may struggle with morning routines and activities.
What if? If a patient with diagnosed melancholic depression also reports loud snoring and significant daytime sleepiness despite the depression treatment, the nurse should suspect a comorbid condition like Obstructive Sleep Apnoea and advocate for a sleep study referral, as untreated OSA can worsen depression and cardiovascular health.

How to Approach the Question

First, identify the core concept of the question: the specific features of 'melancholic depression'.
Next, note the negative framing: the question asks what does 'not' occur.
Recall the classic symptoms of melancholic depression. Key features include anhedonia, lack of mood reactivity, weight loss, and early morning awakening (terminal insomnia).
Evaluate each option against this knowledge base:
Is terminal insomnia a feature? Yes, it's a classic symptom. So, eliminate this.
Is increased REM sleep a feature? Yes, changes in REM are known biological markers. So, eliminate this.

Concept Tested & Keywords

Concept Tested: Differentiating sleep disturbances in subtypes of depression, specifically melancholic versus atypical depression.
Stem keywords: melancholic depression, sleep related disturbance
Lead-in keywords: not occurred
Negative lead-in flag: The question asks which disturbance does NOT occur, requiring the identification of a symptom that is inconsistent with the diagnosis.
