Psychopharmacology for Trauma-Related Disorders Indian Medical PG Practice Questions and MCQs
Question 1: A 32-year-old man comes to the physician complaining of excessive sleepiness for the past several months. He reports falling asleep while dealing with customers and had a near accident when he fell asleep while driving. The patient reports that he occasionally hears voices while falling asleep and finds himself "temporarily frozen" and unable to move upon awakening. Which of the following is the most appropriate treatment for this patient?
- A. Melatonin
- B. Modafinil (Correct Answer)
- C. Clonazepam
- D. Continuous positive airway pressure
Explanation: ***Modafinil*** - The patient's symptoms of **excessive daytime sleepiness** (EDS), **hypnagogic hallucinations** (hearing voices while falling asleep), and **sleep paralysis** are classic signs of **narcolepsy**. - **Modafinil** is a **non-amphetamine stimulant** that promotes wakefulness and is a first-line treatment for narcolepsy, improving alertness and reducing EDS. *Melatonin* - **Melatonin** is a hormone involved in regulating the **sleep-wake cycle** and is primarily used for **insomnia**, **jet lag**, or **circadian rhythm disorders**. - It is not effective for treating the hallmark symptoms of narcolepsy, such as cataplexy or excessive daytime sleepiness. *Clonazepam* - **Clonazepam** is a **benzodiazepine** that acts as a central nervous system depressant, primarily used for **anxiety disorders**, seizures, and some sleep disorders like **REM sleep behavior disorder**. - While it can help with some parasomnias, it would worsen daytime sleepiness in a patient with narcolepsy and is not a primary treatment for its core symptoms. *Continuous positive airway pressure* - **Continuous positive airway pressure (CPAP)** is the standard treatment for **obstructive sleep apnea (OSA)**, a condition characterized by recurrent upper airway collapse during sleep. - Although OSA can cause excessive daytime sleepiness, the patient's additional symptoms of hypnagogic hallucinations and sleep paralysis are not typical of OSA, making narcolepsy and its specific treatments more appropriate.
Question 2: Management of a violent patient in psychiatry includes all except:
- A. CBT (Correct Answer)
- B. Haloperidol
- C. ECT
- D. BZD
Explanation: ***CBT*** - **Cognitive Behavioral Therapy (CBT)** is a long-term psychological intervention aimed at changing maladaptive thought patterns and behaviors. It is **not suitable for immediate management** of an acutely violent patient. - While CBT can be beneficial for aggression management in a stable patient, it requires patient cooperation, cognitive engagement, and time, which are not available during a **violent psychiatric emergency**. *Haloperidol* - **Haloperidol** is a potent typical antipsychotic frequently used in acute settings for rapid tranquilization of violent or severely agitated patients. - It is effective in reducing **psychosis-related agitation** and can be administered **intramuscularly** for quick onset of action. - Often used in combination with benzodiazepines for optimal control of acute violence. *ECT* - **Electroconvulsive Therapy (ECT)** may be considered in **severe, treatment-resistant cases** of violence associated with conditions like uncontrolled mania, catatonic excitement, or psychotic depression when pharmacological interventions have failed. - While not used for immediate acute management due to logistical requirements (consent, anesthesia, specialized setup), it can be an effective option for severe psychiatric conditions with persistent violence. - It works by inducing a brief controlled seizure, which can rapidly alleviate severe symptoms. *BZD* - **Benzodiazepines (BZDs)** like lorazepam or diazepam are **first-line agents** in the acute management of violent or agitated patients due to their rapid anxiolytic, sedative, and muscle relaxant properties. - They are particularly useful for **calming acute agitation** and are often combined with antipsychotics for rapid tranquilization. - Can be administered intramuscularly or intravenously for quick action in psychiatric emergencies.
Question 3: Which of the following is a selective serotonin and norepinephrine reuptake inhibitor?
- A. Fluoxetine
- B. Venlafaxine (Correct Answer)
- C. Sertraline
- D. Aripiprazole
Explanation: ***Venlafaxine*** - **Venlafaxine** is a commonly used antidepressant that inhibits the reuptake of both **serotonin** and **norepinephrine**, making it an SNRI. - Its dual mechanism of action can be effective for a broad range of depressive and anxiety disorders. *Fluoxetine* - **Fluoxetine** is a **selective serotonin reuptake inhibitor (SSRI)**, primarily affecting serotonin levels in the brain. - It does not significantly inhibit norepinephrine reuptake and, thus, is not classified as an SNRI. *Sertraline* - **Sertraline** is another widely prescribed antidepressant that is also a **selective serotonin reuptake inhibitor (SSRI)**. - It works mainly by increasing serotonin availability in the synaptic cleft. *Aripiprazole* - **Aripiprazole** is an **atypical antipsychotic** medication, often used as an adjunct therapy for depression, but its primary mechanism is partial agonism at dopamine D2 and serotonin 5-HT1A receptors, and antagonism at serotonin 5-HT2A receptors. - It is not classified as a selective serotonin and norepinephrine reuptake inhibitor.
Question 4: A mixed α1 blocker and 5-HT1A receptor agonist, used as an antihypertensive agent, is which of the following?
- A. Trimazosin
- B. Tamsulosin
- C. Doxazosin
- D. Urapidil (Correct Answer)
Explanation: ***Urapidil*** - **Urapidil** acts as a **mixed α1-blocker** and has an additional effect as a **5-HT1A receptor agonist**, which contributes to its antihypertensive properties beyond direct vasodilation. - Its unique dual mechanism sets it apart from other alpha-blockers by also modulating serotonin pathways to reduce blood pressure. *Trimazosin* - **Trimazosin** is a **direct-acting peripheral vasodilator** primarily described as an **alpha-adrenergic blocker**, but it does not possess significant 5-HT1A receptor agonist activity. - It is an older antihypertensive medication not commonly used today, with a primary mechanism focused solely on alpha-blocking. *Tamsulosin* - **Tamsulosin** is a **selective α1A-adrenergic receptor antagonist**, specifically used to treat **benign prostatic hyperplasia (BPH)** symptoms by relaxing smooth muscle in the prostate and bladder neck. - It does not have significant 5-HT1A receptor agonist activity, and its primary use is not for general hypertension management. *Doxazosin* - **Doxazosin** is a **selective α1-adrenergic receptor antagonist** used to treat both **hypertension** and **benign prostatic hyperplasia (BPH)**. - While it effectively blocks alpha-1 receptors to lower blood pressure, it does not exert significant agonistic effects on 5-HT1A receptors.
Question 5: What is the drug of choice for rapid relief of an acute panic attack?
- A. Benzodiazepines (rapid anxiolytic action) (Correct Answer)
- B. Neuroleptics (antipsychotic agents)
- C. Beta-blockers (manage physical symptoms)
- D. Tricyclic Antidepressants (long-term management)
Explanation: ***Benzodiazepines (rapid anxiolytic action)*** - **Benzodiazepines** are used for **rapid symptomatic relief** of acute panic attacks due to their **fast onset of action** (within 30-60 minutes) and potent anxiolytic effects. - They work by enhancing the effect of **GABA**, an inhibitory neurotransmitter, leading to CNS depression and reduced anxiety. - **Important note:** While effective for acute relief, benzodiazepines are recommended only for **short-term use** (2-4 weeks) due to risks of dependence, tolerance, and withdrawal. - **First-line long-term treatment** for panic disorder is **SSRIs** (not benzodiazepines). *Beta-blockers (manage physical symptoms)* - **Beta-blockers** can help manage **physical symptoms** of anxiety such as palpitations and tremors, but they do not address the core psychological component of a panic attack. - They are often used as an adjunct or in performance anxiety situations, but not for acute panic attack relief. *Neuroleptics (antipsychotic agents)* - **Neuroleptics** (antipsychotic agents) are primarily used for treating **psychotic disorders** like schizophrenia, not panic attacks. - Their side effect profile and mechanism of action make them unsuitable for acute anxiety or panic. *Tricyclic Antidepressants (long-term management)* - **Tricyclic Antidepressants (TCAs)** like imipramine and clomipramine can be used for **long-term management** of panic disorder. - However, their onset of action is slow (2-4 weeks), making them unsuitable for acute panic attack relief. - **SSRIs are preferred over TCAs** for long-term management due to better tolerability.
Question 6: A patient with a history of RTA before 2 months presents with complaints of dreams of accidents. He is able to visualize the same scene whenever he visits the place. Hence is afraid to go back to the accident site. Identify the type of disorder that he might be suffering from?
- A. PTSD (Correct Answer)
- B. Anxiety disorder
- C. OCD
- D. Adjustment disorder
Explanation: ***PTSD*** - Patients with **Post-Traumatic Stress Disorder (PTSD)** frequently experience **intrusive memories**, **flashbacks**, and **nightmares** related to a traumatic event. - The fear and avoidance of places associated with the trauma are characteristic symptoms, consistent with the patient's reluctance to revisit the accident site. *Anxiety disorder* - While anxiety is a component of PTSD, an **isolated anxiety disorder** would not fully explain the presence of specific **recurrent dreams** and **flashbacks** directly linked to a past traumatic event. - Generalized anxiety often involves **persistent worry about various aspects of life**, rather than focused re-experiencing of a trauma. *OCD* - **Obsessive-Compulsive Disorder (OCD)** is characterized by **recurrent, intrusive thoughts (obsessions)** and **repetitive behaviors (compulsions)** performed to reduce anxiety. - The patient's symptoms of re-experiencing an accident and avoiding the site do not align with the typical presentation of obsessions and compulsions. *Adjustment disorder* - **Adjustment disorder** involves emotional or behavioral symptoms in response to an identifiable stressor, usually resolving within 6 months after the stressor or its consequences have ended. - The described symptoms of **dreams, flashbacks, and specific avoidance** after two months are more intense and prolonged than typically seen in adjustment disorder, pointing towards a more severe trauma-related condition like PTSD.
Question 7: Post-traumatic stress disorder is characterized by all except:
- A. Flashback and nightmare
- B. Re-experiencing stressful events
- C. Exposure to traumatic events
- D. It doesn't develop after 6 months of stress (Correct Answer)
Explanation: ***It doesn't develop after 6 months of stress*** - This statement is **FALSE** and is therefore the correct answer to this "EXCEPT" question. - **PTSD can develop at any time** following a traumatic event, including months or even years later - there is no upper time limit for symptom onset. - The **DSM-5 includes a "delayed expression" specifier** for cases where full diagnostic criteria are not met until at least 6 months after the trauma. - While most cases develop within **3 months of the traumatic event**, delayed onset is well-documented and clinically recognized. - This distinguishes PTSD from **Acute Stress Disorder**, which by definition occurs within 3 days to 4 weeks after trauma exposure. *Flashback and nightmare* - **Flashbacks** (dissociative reactions where the person feels the traumatic event is recurring) and **nightmares** are core symptoms of PTSD. - These belong to the **re-experiencing/intrusion symptom cluster** (Criterion B in DSM-5). - These involuntary recollections cause significant distress and are hallmark features of the disorder. *Re-experiencing stressful events* - **Re-experiencing symptoms** are one of the four main symptom clusters required for PTSD diagnosis. - This includes intrusive memories, traumatic nightmares, flashbacks, and intense psychological/physiological reactions to trauma reminders. - These symptoms reflect the **inability to integrate the traumatic memory** properly, leading to involuntary reactivation. *Exposure to traumatic events* - **Criterion A: Exposure to actual or threatened death, serious injury, or sexual violence** is the essential prerequisite for PTSD diagnosis. - This exposure can be through direct experience, witnessing, learning it happened to a close other, or repeated/extreme exposure to aversive details. - Without documented trauma exposure, PTSD cannot be diagnosed regardless of symptom presentation.
Question 8: Derealization and depersonalization are symptoms of which type of disorder?
- A. Dissociative disorder (Correct Answer)
- B. Personality disorders
- C. Mania
- D. Anxiety disorders
Explanation: ***Dissociative disorder*** - **Derealization** involves experiencing the outside world as unreal or dreamlike - **Depersonalization** is the experience of feeling detached from one's own body or mental processes - These are hallmark symptoms of **dissociative disorders**, specifically depersonalization-derealization disorder in DSM-5 *Personality disorders* - Characterized by enduring, maladaptive patterns of inner experience and behavior - While some personality disorders (e.g., **borderline personality disorder**) may display transient dissociative symptoms under stress, derealization and depersonalization are not core diagnostic features *Mania* - A state of abnormally elevated mood and energy, involving **racing thoughts**, **decreased need for sleep**, and **impulsive behavior** - Does not typically involve consistent derealization or depersonalization as core features *Anxiety disorders* - Depersonalization can occur transiently during **panic attacks** or severe anxiety - However, when derealization and depersonalization are the primary, persistent symptoms, they indicate a **dissociative disorder** rather than an anxiety disorder
Question 9: Ganser syndrome is classified under which of the following disorders?
- A. OCD
- B. Conversion disorder
- C. Dissociative disorder (Correct Answer)
- D. Schizoid personality disorder
Explanation: ***Dissociative disorder*** - Ganser syndrome is characterized by a "passing-off" behavior, where the individual gives **approximate or nonsensical answers** to simple questions, often associated with other dissociative symptoms. - While historically difficult to classify, contemporary understanding places it within the spectrum of dissociative disorders due to its features of an altered state of consciousness and a detachment from reality. *OCD* - **Obsessive-compulsive disorder (OCD)** involves recurrent, intrusive thoughts (obsessions) and repetitive behaviors or mental acts (compulsions). - Ganser syndrome does not typically present with the classic symptom profile of obsessions and compulsions. *Conversion disorder* - **Conversion disorder** involves neurological symptoms (e.g., paralysis, blindness, seizures) that are not consistent with neurological disease and are often preceded by psychological stress. - While both involve psychological factors, Ganser syndrome is distinct in its presentation of "answers" that are close but incorrect, rather than physical symptoms. *Schizoid personality disorder* - **Schizoid personality disorder** is characterized by a pervasive pattern of detachment from social relationships and a restricted range of expression of emotions in interpersonal settings. - This disorder primarily affects social functioning and emotional expression, which is different from the specific cognitive and behavioral pattern seen in Ganser syndrome.
Question 10: To diagnose post-traumatic stress disorder, the symptoms should persist for more than ______
- A. 1 month (Correct Answer)
- B. 2 days
- C. 3 months
- D. 6 months
Explanation: ***1 month*** - According to the **DSM-5 criteria**, for a diagnosis of **Post-Traumatic Stress Disorder (PTSD)**, the symptoms must persist for **more than one month**. - If symptoms last for less than one month, but meet other criteria, the diagnosis is typically **Acute Stress Disorder**. *2 days* - Symptoms lasting only **2 days** following a traumatic event are too short for a diagnosis of PTSD. - Such a brief duration may align with an **acute stress reaction**, which is a normal response to trauma and usually resolves quickly. *3 months* - While symptoms lasting **3 months** would certainly qualify for PTSD in terms of duration, this is not the minimum duration required. - The **minimum duration** for PTSD diagnosis is specifically defined as more than one month. *6 months* - Symptoms persisting for **6 months** or longer clearly meet the duration criteria for PTSD, but this is not the minimal period. - Setting the minimum at 6 months would lead to **underdiagnosis** of PTSD in individuals whose symptoms are significant and disabling after one month but before six months.
