Psychiatric Assessment and Diagnosis Indian Medical PG Practice Questions and MCQs
Question 1: A businessman is brought for psychiatric evaluation due to recent denial of memory of taking multiple bank loans, despite all other memory functions being intact. This is suggestive of which of the following?
- A. Dissociative amnesia (Correct Answer)
- B. Dissociative fugue
- C. Dissociative identity disorder
- D. Dissociative autonomic dysfunction
Explanation: **Explanation:** The clinical presentation describes a patient with selective memory loss related to a specific stressful or traumatic event (taking multiple bank loans) while maintaining an otherwise intact memory. This is the hallmark of **Dissociative Amnesia**. **1. Why Dissociative Amnesia is correct:** Dissociative amnesia is characterized by an inability to recall important personal information, usually of a stressful or traumatic nature, that is too extensive to be explained by ordinary forgetfulness. In this case, the businessman’s "denial" is not a conscious lie (malingering) but a psychological defense mechanism where the memory is sequestered from conscious awareness. Crucially, there is no underlying organic brain pathology, and general cognitive functions remain preserved. **2. Why other options are incorrect:** * **Dissociative Fugue:** This involves sudden, unexpected travel away from home combined with an inability to recall one’s past and, occasionally, the assumption of a new identity. The patient here has not traveled or lost his identity. * **Dissociative Identity Disorder (DID):** This requires the presence of two or more distinct personality states that take control of behavior, accompanied by gaps in memory. There is no evidence of multiple personalities here. * **Dissociative Autonomic Dysfunction:** This refers to physical symptoms (like palpitations or tremors) mediated by the autonomic nervous system that have a psychological origin. It does not involve memory loss. **Clinical Pearls for NEET-PG:** * **Localized Amnesia:** The most common type; failure to recall events during a specific period. * **Selective Amnesia:** Can remember some, but not all, events during a specific period (as seen in this businessman). * **Primary Gain:** Keeping the internal conflict out of awareness. * **Secondary Gain:** Tangible external benefits (e.g., avoiding loan repayment), though the amnesia itself is an unconscious process. * **Treatment:** The first-line approach is usually psychotherapy; "Amobarbital interviews" (Narcoanalysis) can sometimes be used to recover memories.
Question 2: A 41-year-old male presents with complaints of inability to achieve proper erections during sexual intercourse. He reports that there were no abnormalities until last month, when on one occasion he tried having sex while he was drunk. He was not able to achieve a proper erection at that time, and since then, on four other occasions, he has been unable to have an erection during attempted sex. He reports that his morning erections are fine and erections during masturbation were also normal. He is a diabetic, and the blood reports show FBS-103 mg/dl, HbA1C-6.6. His BP was 138/88 mm Hg. What is the likely cause of his erection disturbances?
- A. Anxiety (Correct Answer)
- B. Diabetes
- C. Alcohol use
- D. Hypertension
Explanation: **Explanation** The clinical presentation points toward **Psychogenic Erectile Dysfunction (ED)**, specifically triggered by **Performance Anxiety**. **Why Anxiety is the correct answer:** The hallmark of psychogenic ED is the **situational nature** of the symptoms. The patient reports normal morning erections (nocturnal penile tumescence) and normal erections during masturbation. This confirms that the physiological mechanisms (neurological, vascular, and hormonal) required for an erection are intact. The dysfunction began after a single failure (likely due to alcohol's sedative effect), leading to a "vicious cycle" where the fear of failure (performance anxiety) triggers a sympathetic nervous system surge, preventing the parasympathetic response necessary for an erection. **Why other options are incorrect:** * **Diabetes & Hypertension:** While both are common causes of *organic* ED due to microvascular and endothelial damage, organic ED is typically gradual in onset and characterized by the **absence** of morning or masturbatory erections. This patient’s HbA1C (6.6) and BP are relatively well-controlled. * **Alcohol use:** While acute alcohol ingestion can cause temporary ED (as seen in his first episode), it does not explain the subsequent failures while sober, especially when nocturnal erections remain preserved. **Clinical Pearls for NEET-PG:** * **Organic vs. Psychogenic ED:** If spontaneous morning erections are present, the cause is almost always psychogenic. * **Performance Anxiety:** This is the most common cause of psychogenic ED in young and middle-aged men. * **Nocturnal Penile Tumescence (NPT) Test:** Used to differentiate organic from psychogenic ED. A positive NPT (erections during sleep) confirms a psychogenic etiology. * **Diabetes:** The most common organic cause of ED due to a combination of neuropathy and angiopathy.
Question 3: Which of the following statements is FALSE regarding Somatization Disorder?
- A. Involves at least two sexual symptoms. (Correct Answer)
- B. Involves at least two gastrointestinal symptoms.
- C. Involves at least four pain symptoms.
- D. Involves multiple recurrent symptoms.
Explanation: **Explanation:** Somatization Disorder (historically known as Briquet’s Syndrome) is characterized by multiple, recurrent, and clinically significant physical complaints that cannot be fully explained by a general medical condition. According to the **DSM-IV criteria**, a definitive diagnosis requires a specific pattern of symptoms known as the **4-2-2-1 criteria**. **Why Option A is the Correct (False) Statement:** The DSM-IV criteria for Somatization Disorder require at least **one sexual or reproductive symptom** (e.g., sexual indifference, erectile dysfunction, irregular menses, or excessive menstrual bleeding), not two. Therefore, the statement "Involves at least two sexual symptoms" is incorrect. **Analysis of Other Options:** * **Option B:** Correct per criteria. The patient must report at least **two gastrointestinal symptoms** other than pain (e.g., nausea, bloating, vomiting, or diarrhea). * **Option C:** Correct per criteria. The patient must report a history of at least **four pain symptoms** involving different sites (e.g., head, abdomen, back, joints, or during urination). * **Option D:** Correct. The hallmark of the disorder is **multiple recurrent symptoms** that typically begin before age 30 and persist for several years. **High-Yield Clinical Pearls for NEET-PG:** * **DSM-5 Update:** In DSM-5, Somatization Disorder has been replaced by **Somatic Symptom Disorder (SSD)**. The focus has shifted from the number of symptoms to the patient's excessive thoughts, feelings, and behaviors regarding those symptoms. * **Gender Ratio:** It is significantly more common in females (5-20 times more frequent). * **Comorbidity:** Frequently associated with Anxiety and Depressive disorders. * **Management:** The primary goal is management, not cure. Regular, brief scheduled visits with a single primary care physician are recommended to avoid unnecessary invasive investigations.
Question 4: Akinesia (hypoactivity) and mutism is a feature of which of the following states?
- A. Twilight state
- B. Stupor (Correct Answer)
- C. Cataplexy
- D. Torpor
Explanation: ### Explanation **Correct Answer: B. Stupor** **Understanding the Concept:** In psychiatry and neurology, **Stupor** is defined as a state of deep mental and physical inactivity where the patient is motionless (**akinesia**) and silent (**mutism**). Although the patient appears unresponsive, they maintain a level of consciousness (unlike a coma) and can often be aroused briefly by vigorous or painful stimuli. In psychiatric practice, stupor is most commonly associated with **Catatonic Schizophrenia**, **Depressive Stupor**, or organic brain syndromes. **Analysis of Incorrect Options:** * **A. Twilight State:** This is a condition of "clouding of consciousness" where the patient is oriented to their internal dream-like world but disconnected from the environment. It is characterized by complex, often violent, purposeless behaviors with subsequent amnesia (commonly seen in Epilepsy). * **C. Cataplexy:** This is a sudden, temporary loss of muscle tone triggered by strong emotions (like laughter or anger), leading to collapse. Crucially, consciousness is fully preserved, and it is a hallmark of **Narcolepsy**. * **D. Torpor:** This refers to a state of lowered physiological activity, typically characterized by reduced body temperature and metabolic rate. In a clinical sense, it is a mild form of drowsiness or sluggishness, but it does not specifically define the combination of akinesia and mutism. **High-Yield Clinical Pearls for NEET-PG:** * **Catatonic Stupor:** The most common psychiatric cause. Look for "waxy flexibility" (cerea flexibilitas) or "negativism" in the clinical vignette. * **Differential Diagnosis:** Always rule out organic causes (e.g., encephalitis, metabolic encephalopathy) before diagnosing psychiatric stupor. * **Management:** For catatonic stupor, the first-line treatment is **Intravenous Benzodiazepines** (Lorazepam challenge test) or **Electroconvulsive Therapy (ECT)** if the patient is non-responsive or medically unstable.
Question 5: A 27-year-old librarian is worried that small lymph nodes palpable in her groin are a sign of lymphoma and that exposure to second-hand smoke at home may lead to laryngeal cancer. For a diagnosis of hypochondriasis, her symptoms should have been present for at least what period of time?
- A. 1 month
- B. 3 months
- C. 6 months (Correct Answer)
- D. 1 year
Explanation: ### Explanation **Correct Answer: C. 6 months** The clinical presentation describes **Hypochondriasis** (now referred to as **Illness Anxiety Disorder** in DSM-5). According to both ICD-10 and DSM-5 criteria, the preoccupation with having a serious medical illness must persist for **at least 6 months** for a definitive diagnosis. **Underlying Medical Concept:** Hypochondriasis is characterized by a persistent preoccupation or fear of having a serious disease based on a misinterpretation of bodily symptoms (like palpable lymph nodes). Even after appropriate medical evaluation and reassurance, the patient’s anxiety remains high. The 6-month duration is a diagnostic threshold used to differentiate transient health anxiety (common during periods of stress) from a chronic psychiatric disorder. **Why Other Options are Incorrect:** * **A & B (1 month & 3 months):** These durations are too short for a diagnosis of Hypochondriasis. While symptoms may be present, they do not yet meet the longitudinal criteria required to establish chronicity in somatoform or anxiety-related disorders. * **D (1 year):** While the symptoms may certainly last for a year or longer, the minimum diagnostic requirement is 6 months. Waiting for one year would unnecessarily delay diagnosis and intervention. --- ### High-Yield Pearls for NEET-PG: * **DSM-5 Update:** Hypochondriasis is now largely categorized as **Illness Anxiety Disorder** (if somatic symptoms are absent or mild) or **Somatic Symptom Disorder** (if significant physical symptoms are present). * **Key Feature:** The core of the disorder is **misinterpretation** of signs/sensations, not the symptoms themselves. * **Doctor Shopping:** These patients frequently visit multiple specialists and undergo repeated investigations despite negative results. * **Treatment of Choice:** Cognitive Behavioral Therapy (CBT) is the primary treatment; SSRIs are useful if there is comorbid anxiety or depression.
Question 6: Which of the following is NOT a diagnostic/defining criterion for amnestic disorder?
- A. Visual hallucination
- B. Transient delusion
- C. Impaired concentration/attention
- D. All of the above (Correct Answer)
Explanation: **Explanation:** The core feature of **Amnestic Disorder** (now classified under Major Neurocognitive Disorder in DSM-5) is a **selective impairment in memory** (both anterograde and retrograde) without significant impairment in other domains of cognitive functioning. **Why "All of the above" is correct:** Amnestic disorder is defined by a focal deficit in memory. The presence of other cognitive or perceptual disturbances actually points toward *different* psychiatric or neurological diagnoses: * **Visual Hallucinations & Transient Delusions (Options A & B):** These are characteristic of **Psychotic Disorders** or **Delirium**. While "confabulation" (filling memory gaps with fabricated stories) is common in amnestic disorders like Korsakoff’s Syndrome, it is not a true delusion or hallucination. * **Impaired Concentration/Attention (Option C):** This is the hallmark of **Delirium**. In a pure amnestic disorder, the patient’s level of consciousness and attention span remain intact; they simply cannot retain new information. **Clinical Pearls for NEET-PG:** * **The "Rule of Exclusion":** To diagnose Amnestic Disorder, you must rule out **Delirium** (which involves clouded consciousness/attention) and **Dementia** (which involves multiple cognitive deficits like aphasia, apraxia, or executive dysfunction). * **Wernicke-Korsakoff Syndrome:** The most common cause is Thiamine (B1) deficiency. Wernicke’s is the acute phase (Ataxia, Ophthalmoplegia, Confusion), while Korsakoff’s is the chronic amnestic phase (marked by anterograde amnesia and confabulation). * **Key Distinction:** If a patient has memory loss **plus** impaired attention, the diagnosis is **Delirium**. If they have memory loss **plus** agnosia/aphasia, it is **Dementia**. Memory loss **alone** is Amnestic Disorder.
Question 7: Which category of ICD is associated with mood disorders?
- A. F0
- B. F1
- C. F2
- D. F3 (Correct Answer)
Explanation: The **International Classification of Diseases (ICD-10)**, Chapter V, classifies mental and behavioral disorders using the prefix **'F'**. Understanding this classification is high-yield for NEET-PG as it forms the basis of clinical diagnosis. ### **Correct Option: D (F3)** The **F30–F39** block is dedicated to **Mood (Affective) Disorders**. These are conditions where the fundamental disturbance is a change in affect or mood, usually accompanied by a change in the overall level of activity. Key examples include: * **F31:** Bipolar Affective Disorder * **F32/F33:** Depressive Episodes / Recurrent Depressive Disorder * **F34:** Persistent mood disorders (e.g., Cyclothymia, Dysthymia) ### **Analysis of Incorrect Options:** * **A. F0 (Organic Mental Disorders):** Includes disorders due to brain disease or systemic illness (e.g., **Dementia** in Alzheimer’s, Delirium). * **B. F1 (Mental and Behavioral Disorders due to Psychoactive Substance Use):** Covers disorders resulting from the use of alcohol, opioids, cannabinoids, and stimulants (e.g., **Dependence Syndrome**). * **C. F2 (Schizophrenia, Schizotypal, and Delusional Disorders):** This category covers psychotic disorders characterized by distortions in thinking, perception, and affect. ### **High-Yield Clinical Pearls for NEET-PG:** * **F4:** Neurotic, stress-related, and somatoform disorders (e.g., **OCD, Panic Disorder, PTSD**). * **F5:** Behavioral syndromes associated with physiological disturbances (e.g., **Eating disorders, Sleep disorders**). * **F7:** Mental Retardation (Intellectual Disability). * **Note:** While ICD-10 is currently the standard for exams, **ICD-11** has been released, where the 'F' codes are replaced by **Chapter 06** (Mental, behavioral or neurodevelopmental disorders). However, NEET-PG frequently tests the classic ICD-10 'F' categories.
Question 8: All are true statements about Conversion disorder except?
- A. Autonomic nervous system is involved (Correct Answer)
- B. There is primary and secondary gain
- C. La belle indifference is a feature
- D. Patient does not intentionally produce symptoms
Explanation: **Explanation:** Conversion Disorder (Functional Neurological Symptom Disorder) is characterized by neurological symptoms that cannot be explained by a known neurological or medical condition. **Why Option A is the correct answer (False statement):** Conversion disorder primarily involves **voluntary motor or sensory functions** (e.g., paralysis, blindness, seizures). The **Autonomic Nervous System (ANS)**, which controls involuntary functions like heart rate, digestion, and pupillary response, is **not** typically involved in conversion symptoms. If autonomic instability is prominent, clinicians should investigate other medical etiologies or Somatization disorder. **Analysis of other options:** * **Option B (Primary and Secondary Gain):** These are classic psychodynamic concepts. **Primary gain** is the internal relief achieved by keeping an emotional conflict out of conscious awareness (e.g., a soldier develops leg paralysis to avoid the guilt of combat). **Secondary gain** refers to external benefits derived from being ill, such as avoiding work or gaining attention. * **Option C (La belle indifference):** This refers to a paradoxical lack of concern regarding the severity of the symptoms. While classic, it is neither pathognomonic nor required for diagnosis. * **Option D (Not intentionally produced):** This is the key differentiator from **Factitious Disorder** and **Malingering**. In Conversion disorder, the patient truly experiences the symptoms; they are not "faking" or consciously producing them. **NEET-PG Clinical Pearls:** * **DSM-5 Criteria:** Requires clinical findings that show **incompatibility** between the symptom and recognized neurological conditions (e.g., Hoover’s sign for leg weakness). * **Most common symptoms:** Paralysis, blindness, and aphonia. * **Treatment:** The first-line treatment is **Education** about the diagnosis, followed by Physical Therapy and CBT. * **Prognosis:** Good prognostic factors include sudden onset, presence of an identifiable stressor, and good premorbid health.
Question 9: Awareness of having a disease is termed as:
- A. Insight (Correct Answer)
- B. Perseveration
- C. Delusion
- D. Incoherence
Explanation: **Explanation:** The correct answer is **Insight (Option A)**. In psychiatry, insight refers to a patient's degree of awareness and understanding of their own mental health condition. It is a multi-dimensional construct that includes recognizing that one has a mental illness, understanding the need for treatment, and correctly attributing unusual experiences (like hallucinations) to the illness rather than external reality. **Analysis of Incorrect Options:** * **B. Perseveration:** This is a disorder of the *form of thought* characterized by the persistent repetition of a specific response (such as a word, phrase, or gesture) despite the absence or cessation of a stimulus. It is commonly seen in organic brain disorders and schizophrenia. * **C. Delusion:** This is a disorder of *thought content*. It is defined as a fixed, false belief that is out of keeping with the patient’s social, cultural, and educational background and is held with absolute conviction despite logical evidence to the contrary. * **D. Incoherence:** This is a severe disorder of the *form of thought* where speech is disconnected and unintelligible, often referred to as "word salad." **High-Yield Clinical Pearls for NEET-PG:** * **Levels of Insight:** Insight is not "all-or-none" but is graded on a scale of 1 to 6 (from complete denial to true emotional insight). * **Clinical Significance:** Loss of insight is a hallmark of **Psychosis** (e.g., Schizophrenia, Mania), whereas insight is typically preserved in **Neurosis** (e.g., Anxiety disorders, OCD). * **Prognostic Value:** Insight is the single best predictor of treatment compliance and long-term prognosis in psychiatric patients.
Question 10: A 25-year-old female presents with a 6-month history of altered sensorium, involuntary movements, memory deficit, headache, convulsions, abnormal movements, forgetfulness, with 4 attacks during the day and 2 attacks at night. CT scan is normal. What is the most likely diagnosis?
- A. Epilepsy (Correct Answer)
- B. Dissociative disorder
- C. Hypochondriasis
- D. Somatization disorder
Explanation: **Explanation:** The clinical presentation of altered sensorium, involuntary movements, memory deficits, headaches, and convulsions strongly points toward a neurological etiology rather than a primary psychiatric one. **Why Epilepsy is the Correct Answer:** The presence of **nocturnal attacks** (2 attacks at night) is the most critical diagnostic "red flag" that differentiates organic seizures from psychiatric conditions. Dissociative (pseudo) seizures almost exclusively occur in the presence of an audience and are extremely rare during sleep. Furthermore, the combination of convulsions with altered sensorium, post-ictal memory deficits (forgetfulness), and headaches are classic hallmarks of **Epilepsy**. While a CT scan is normal, this does not rule out epilepsy, as many seizure disorders (especially idiopathic or functional types) do not show structural lesions on imaging. **Why Other Options are Incorrect:** * **Dissociative Disorder (Dissociative Seizures):** These are typically characterized by emotional triggers, lack of tongue biting or incontinence, and, most importantly, they **do not occur during sleep**. * **Hypochondriasis (Illness Anxiety Disorder):** This involves a preoccupation with having a serious illness based on a misinterpretation of bodily symptoms, not the presentation of acute neurological deficits like convulsions or altered sensorium. * **Somatization Disorder (Somatic Symptom Disorder):** While this involves multiple physical symptoms, the presence of objective neurological signs (convulsions) and nocturnal episodes makes a primary medical condition (Epilepsy) the priority diagnosis. **NEET-PG High-Yield Pearls:** * **Nocturnal episodes** are the single best clinical predictor of true epilepsy over dissociative seizures. * **Prolactin levels:** Elevated 15–30 minutes post-ictally in true generalized seizures; remains normal in dissociative seizures. * **Normal Imaging:** A normal CT/MRI does not exclude epilepsy; EEG is the gold standard for functional assessment.
