Mood Disorders Practice Questions

Q: Which medication is DOC for rapid cycling Bipolar Affective Disorder?

Valproate. **Explanation:** **Rapid Cycling Bipolar Affective Disorder (BPAD)** is defined by the occurrence of **four or more mood episodes** (manic, hypomanic, or depressive) within a 12-month period. 1. **Why Valproate is Correct:** While Lithium remains the gold standard for classic BPAD, **Sodium Valproate** is the **Drug of Choice (DOC)** for rapid cycling and mixed episodes. Valproate has shown superior efficacy in stabilizing mood fluctuations in patients who do not respond well to Lithium. Its mechanism involves enhancing GABAergic transmission and modulating glutamate and voltage-gated sodium channels, which provides a broader spectrum of anti-cycling activity. 2. **Why Other Options are Incorrect:** * **Lithium:** Although the first-line treatment for prophylaxis and acute mania, it is notoriously **less effective** in rapid cycling variants. * **Carbamazepine:** This is considered a second-line mood stabilizer. It is used when patients are intolerant to Valproate or Lithium but is generally not the first choice for rapid cycling. * **Calcium Channel Blockers (e.g., Verapamil):** These have very limited evidence in mood stabilization and are never used as first-line monotherapy for rapid cycling. **High-Yield Clinical Pearls for NEET-PG:** * **DOC for Acute Mania:** Lithium (if mild/moderate); Valproate or Antipsychotics (if severe). * **DOC for BPAD in Pregnancy:** Second-generation antipsychotics (e.g., Quetiapine). Avoid Lithium (Ebstein’s anomaly) and Valproate (Neural tube defects) in the first trimester. * **Therapeutic Range for Lithium:** 0.8–1.2 mEq/L (Acute); 0.6–1.0 mEq/L (Maintenance). * **Antidepressant-Induced Cycling:** Always rule out antidepressant use as a cause for rapid cycling before intensifying mood stabilizer therapy.

Q: A patient presents with depressed mood, loss of sleep, loss of hope, feeling of worthlessness, and diminished concentration for the past month. Which of the following is the drug of choice in this patient?

SSRIs (Selective Serotonin Reuptake Inhibitors). ### Explanation **1. Why SSRIs are the Correct Choice:** The patient presents with classic symptoms of **Major Depressive Disorder (MDD)**: depressed mood, insomnia, hopelessness, worthlessness, and poor concentration, lasting for more than two weeks. According to current clinical guidelines (APA and NICE), **Selective Serotonin Reuptake Inhibitors (SSRIs)** are the **first-line treatment** for MDD. They are preferred because of their favorable safety profile, better tolerability, and lower risk of toxicity in overdose compared to older antidepressants. **2. Analysis of Incorrect Options:** * **B. Atypical Antidepressants:** While effective (e.g., Bupropion, Mirtazapine), these are generally considered second-line or used in specific scenarios (e.g., Bupropion if sexual dysfunction is a concern). * **C. Lithium:** This is the drug of choice for **Bipolar Affective Disorder (BPAD)** prophylaxis and acute mania. While it can augment antidepressants in treatment-resistant depression, it is not the initial drug of choice for unipolar depression. * **D. Tricyclic Antidepressants (TCAs):** Though equally effective as SSRIs, TCAs are no longer first-line due to significant side effects (anticholinergic, antihistaminic, anti-alpha-1) and high **cardiotoxicity** in overdose (prolonged QTc). **3. NEET-PG High-Yield Pearls:** * **Most common side effect of SSRIs:** Gastrointestinal upset (nausea/diarrhea). * **Most common long-term side effect:** Sexual dysfunction. * **Fluoxetine:** Has the longest half-life (ideal for patients who forget doses). * **Fluvoxamine:** Specifically indicated for Obsessive-Compulsive Disorder (OCD). * **Sertraline:** Considered the safest SSRI post-Myocardial Infarction (MI). * **Escitalopram:** Known for having the highest specificity for the serotonin transporter.

Q: All of the following are true about mania except?

Word salad. **Explanation:** The correct answer is **D. Word salad**. In psychiatry, **Word Salad** (schizophasia) is a severe form of thought form disorder characterized by a random jumble of words that lack any logical or grammatical connection. It is a hallmark feature of **Schizophrenia** (specifically disorganized type) rather than Mania. **Analysis of Options:** * **A. Elevated mood:** This is the core emotional feature of Mania. The mood is typically described as euphoric, expansive, or irritable, lasting for at least one week. * **B. Flight of ideas:** This is the classic **thought form disorder** seen in Mania. It involves a rapid succession of thoughts where ideas are connected by chance associations (e.g., clanging or punning), but a thin thread of logic usually remains, unlike word salad. * **C. Delusions of grandeur:** These are common **thought content disorders** in Mania. Patients have inflated self-esteem and believe they possess special powers, wealth, or a unique relationship with a deity or famous person. **Clinical Pearls for NEET-PG:** 1. **DIGFAST Mnemonic for Mania:** **D**istractibility, **I**ndiscretion (excessive involvement in pleasurable activities), **G**randiosity, **F**light of ideas, **A**ctivity increase, **S**leep deficit (decreased need for sleep), **T**alkativeness (pressured speech). 2. **Pressure of Speech:** In Mania, speech is rapid, loud, and difficult to interrupt. 3. **Distinction:** While "Flight of Ideas" is characteristic of **Mania**, "Loosening of Associations" and "Word Salad" are more characteristic of **Schizophrenia**. 4. **Hypomania vs. Mania:** Hypomania lasts ≥4 days, does not require hospitalization, and lacks psychotic features. Mania lasts ≥1 week or requires hospitalization.

Q: What is paradoxical suicide?

Suicide observed after the initiation of treatment.. ### Explanation **Paradoxical suicide** refers to a phenomenon where a patient with severe depression commits suicide shortly after starting treatment (pharmacotherapy or psychotherapy) or during the early stages of recovery. **Why Option D is Correct:** In severe depression, patients often suffer from **psychomotor retardation**—a state where they lack the physical energy and motivation to carry out a suicide plan, despite having suicidal ideation. When treatment (like SSRIs) begins, physical energy and motivation often improve **before** the depressive mood and hopelessness lift. This "energy gap" creates a window where the patient now has the physical drive to act on their pre-existing suicidal thoughts. This is why the risk of suicide paradoxically increases in the first few weeks of antidepressant therapy. **Why Other Options are Incorrect:** * **Options A, B, and C:** While family members and caregivers of depressed patients are at a higher risk for depression and "caregiver burnout," their suicidal behavior is not termed "paradoxical suicide." These would be categorized under the genetic or environmental transmission of mental illness. **High-Yield Clinical Pearls for NEET-PG:** * **The "Danger Zone":** The highest risk for paradoxical suicide is typically within the first **10 to 14 days** of starting antidepressants. * **Black Box Warning:** The FDA has a black box warning for SSRIs regarding increased suicidal thoughts and behaviors in children, adolescents, and young adults (up to age 24). * **Clinical Management:** Always monitor patients closely during the initial phase of treatment. If a patient suddenly appears "energetic" but still expresses hopelessness, it is a major red flag. * **ECT:** Electroconvulsive Therapy (ECT) is often preferred in actively suicidal patients because it works faster than drugs to bridge this dangerous gap.

Q: Which of the following is not a part of Beck's triad?

Sleeplessness. **Explanation:** **Beck’s Cognitive Triad** is a core concept in the cognitive theory of depression developed by Aaron Beck. It describes three specific patterns of negative thinking that maintain depressive symptoms. The triad consists of negative views about: 1. **The Self (Worthlessness):** The individual perceives themselves as defective, inadequate, or lacking the necessary requirements for happiness. 2. **The World/Environment (Helplessness):** The individual interprets ongoing experiences in a negative way, believing the world makes exorbitant demands or presents insuperable obstacles. 3. **The Future (Hopelessness):** The individual anticipates that current difficulties or suffering will continue indefinitely. **Why Sleeplessness is the correct answer:** Sleeplessness (Insomnia) is a **somatic (physical) symptom** of depression, not a cognitive one. While it is a common diagnostic criterion for Major Depressive Disorder (MDD) in the DSM-5, it is not part of Beck’s psychological model of cognitive distortions. **Analysis of Incorrect Options:** * **Hopelessness:** Represents the negative view of the **future**. It is a strong predictor of suicidal intent. * **Worthlessness:** Represents the negative view of the **self**. * **Helplessness:** Represents the negative view of the **world/current situation**, where the individual feels they have no control over their environment. **High-Yield Clinical Pearls for NEET-PG:** * **Cognitive Behavioral Therapy (CBT):** Aimed at identifying and restructuring these three negative schemas. * **Learned Helplessness:** A related but distinct concept developed by **Martin Seligman** (based on animal models). * **Suicide Risk:** Among the triad, **Hopelessness** is the most significant indicator of long-term suicidal risk.

Q: Which of the following is associated with neurotic depression?

Usually associated with anxiety. **Explanation:** In psychiatry, **Neurotic Depression** (also known as Dysthymia or Persistent Depressive Disorder in modern terminology) is characterized by a chronic, low-grade depressive state that is often triggered by external stressors or personality factors. **1. Why Option A is Correct:** Neurotic depression is frequently characterized by a "mixed" clinical picture. Unlike psychotic or endogenous depression, it is **usually associated with anxiety**, irritability, and somatic complaints. Patients often remain in touch with reality but struggle with chronic dissatisfaction and emotional instability. **2. Why the other options are incorrect:** * **Option B (ECT):** Electroconvulsive Therapy (ECT) is indicated for severe, biological, or "melancholic" depression, especially when there is a high suicide risk or catatonia. It is rarely, if ever, used for neurotic depression, which responds better to psychotherapy and SSRIs. * **Option C (Endogenous depression):** This is the opposite of neurotic depression. Endogenous depression arises from internal biological factors (not external stressors), presents with "vegetative" symptoms (weight loss, early morning awakening), and is often more severe. * **Option D (Bipolar):** Neurotic depression is typically unipolar. Bipolar disorder involves distinct episodes of mania or hypomania, which are absent in neurotic/dysthymic patterns. **High-Yield Clinical Pearls for NEET-PG:** * **Neurotic vs. Psychotic Depression:** In neurotic depression, reality testing is intact, and there are no delusions or hallucinations. * **Diurnal Variation:** In endogenous depression, symptoms are worse in the morning; in neurotic depression, symptoms often worsen as the day progresses (**evening worsening**). * **Treatment:** The mainstay for neurotic depression is a combination of **Cognitive Behavioral Therapy (CBT)** and Pharmacotherapy (SSRIs).

Q: What is the drug of choice in acute mania?

Risperidone. **Explanation:** In the management of **acute mania**, the primary goal is rapid symptom control. While multiple drug classes are effective, **Atypical Antipsychotics (Second-Generation Antipsychotics)** are currently considered the first-line treatment of choice due to their rapid onset of action compared to mood stabilizers. **Why Risperidone is Correct:** Risperidone is a potent atypical antipsychotic that provides rapid sedation and control of manic symptoms (agitation, flight of ideas, and psychosis). In acute clinical settings, antipsychotics work faster (within hours to days) than Lithium or Valproate, which may take 5–10 days to reach therapeutic levels and show clinical efficacy. **Analysis of Incorrect Options:** * **Lithium (A):** Traditionally the "gold standard" for long-term maintenance and prophylaxis of Bipolar Disorder. However, in acute mania, its slow onset and narrow therapeutic index make it a second-line choice for immediate stabilization compared to antipsychotics. * **Chlorpromazine (B):** A typical (first-generation) antipsychotic. While effective, it is no longer the drug of choice due to a higher side-effect profile, including extrapyramidal symptoms (EPS) and significant sedation. * **Valproic acid (C):** An excellent mood stabilizer, especially for "mixed episodes" or "rapid cycling." Like Lithium, it has a slower onset of action than Risperidone in an acute crisis. **High-Yield Clinical Pearls for NEET-PG:** * **First-line for Acute Mania:** Atypical Antipsychotics (Risperidone, Olanzapine, Haloperidol). * **Best for Maintenance/Suicide Prevention:** Lithium. * **Best for Mixed Episodes/Rapid Cycling:** Valproate. * **Pregnancy:** Avoid Lithium (Ebstein’s anomaly) and Valproate (Neural tube defects). Antipsychotics or ECT are preferred. * **Severe Mania:** Combination therapy (Lithium/Valproate + an Antipsychotic) is often superior to monotherapy.

Q: What is the treatment of choice for prophylaxis in patients with repeated episodes of bipolar illness?

Lithium and Valproate. **Explanation:** The management of Bipolar Affective Disorder (BPAD) often requires long-term prophylaxis to prevent relapses of both mania and depression. **Why Option C is Correct:** While Lithium and Valproate are both first-line agents individually, clinical evidence (notably the **BALANCE trial**) and various treatment guidelines (such as CANMAT) indicate that **combination therapy with Lithium and Valproate** is more effective than monotherapy for preventing relapse in patients with repeated episodes. This synergistic approach provides superior stabilization of mood, especially in patients who have failed monotherapy or those with high-frequency cycling. **Why Other Options are Incorrect:** * **Option A (Lithium):** Historically the "gold standard" for prophylaxis and excellent for preventing manic relapses and reducing suicide risk. However, as monotherapy, it may not be sufficient for patients with "repeated episodes" or rapid cycling compared to the combination. * **Option B (Valproate):** An effective first-line mood stabilizer, particularly for mixed episodes and rapid cycling. However, like Lithium, its efficacy in preventing all-cause relapse is statistically lower when used alone compared to the combination. **High-Yield Clinical Pearls for NEET-PG:** * **Therapeutic Index:** Lithium has a narrow therapeutic index. Prophylactic blood levels should be maintained between **0.6 – 0.8 mEq/L**. * **Drug of Choice (DOC):** * Acute Mania: Lithium (or Valproate). * Rapid Cycling BPAD: Valproate. * BPAD in Pregnancy: Second-generation antipsychotics (avoid Lithium/Valproate due to teratogenicity like Ebstein’s anomaly and Neural Tube Defects). * **Suicide Prevention:** Lithium is the only mood stabilizer proven to reduce the risk of completed suicide in BPAD patients.
