A patient complaints of sadness of mood, increased letharg, early morning awakening, loss of interest and repos no will to live and hears voices asking her to kill self. What is the diagnosis?
**Core Concept:** Major Depressive Disorder (MDD) is a mental health disorder characterized by significant disturbances in mood, behavior, and cognition, leading to impaired daily functioning. MDD is classified as a psychiatric diagnosis within the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and the International Classification of Diseases (ICD-11).
**Why the Correct Answer is Right:** In this case, the correct answer is **D.** Major Depressive Disorder (MDD) because the patient presents with a constellation of symptoms that align with the diagnostic criteria outlined in the DSM-5 and ICD-11. MDD symptoms include sad mood, loss of interest or pleasure, significant weight loss or gain, insomnia or hypersomnia, psychomotor agitation or retardation, fatigue or loss of energy, feelings of worthlessness or excessive guilt, concentration difficulties, recurrent thoughts of death or suicide, and either one episode or recurrent episodes.
**Why Each Wrong Option is Incorrect:**
A. **Option A (Bipolar Disorder):** While bipolar disorder involves mood swings, the patient's symptoms are more consistent with a single episode of MDD rather than a bipolar episode with hypomania or mania.
B. **Option B (Schizophrenia):** Schizophrenia is a psychiatric disorder characterized by a range of symptoms, including delusions, hallucinations, disorganized speech, catatonia, and negative symptoms. The described symptoms (e.g., hearing voices telling her to kill herself) are more consistent with MDD than schizophrenia.
C. **Option C (Postpartum Depression):** Postpartum depression typically develops within four weeks of childbirth and is often related to hormonal changes. The described symptoms are more consistent with a generalized MDD episode rather than a postpartum episode.
D. **Option D (Major Depressive Disorder):** As mentioned earlier, the patient presents with a range of symptoms, including sad mood, loss of interest, fatigue, suicidal ideation, etc., which align with the diagnostic criteria for MDD.
E. **Option E (Anxiety Disorder):** While anxiety disorders can present with symptoms like insomnia or hypersomnia, the described symptoms are more consistent with MDD than an anxiety disorder.
**Clinical Pearl:** It is essential to consider MDD when assessing a patient with significant depressive symptoms, suicidal ideation, and impaired daily functioning. A proper clinical evaluation and thorough history-taking are crucial to differentiate between MDD and other psychiatric disorders and initiate appropriate treatment.
**Correct Answer: D.** Major Depressive Disorder (MDD) is the correct diagnosis based on the described symptoms, including sad mood, loss of interest, fatigue, suicidal ideation, etc., which align with the diagnostic criteria for MDD.
