Psychotic Disorders Practice Questions

Q: Erotomania is a?

Delusional disorder. **Explanation:** **Erotomania** (also known as **de Clérambault’s Syndrome**) is a subtype of **Delusional Disorder**. It is characterized by the fixed, false belief that another person—usually of higher social status, a celebrity, or a public figure—is deeply in love with the patient. Despite clear evidence to the contrary, the patient maintains this conviction and often attempts to contact the object of their affection. **Why the other options are incorrect:** * **Mood Disorders:** While mood symptoms can sometimes coexist, erotomania is primarily a disorder of thought content (delusion) rather than a primary disturbance of affect (like Depression or Bipolar Disorder). * **Impulse Control Disorders:** These involve a failure to resist an urge or temptation (e.g., Kleptomania). While an erotomanic patient may act impulsively to reach their "lover," the core pathology is the delusion itself. * **Personality Disorders:** These are enduring, pervasive patterns of inner experience and behavior. While certain personalities (like Paranoid) may predispose one to delusional thinking, Erotomania is classified as a specific psychotic disorder. **High-Yield Clinical Pearls for NEET-PG:** * **Demographics:** It is more commonly diagnosed in females, though males may exhibit more aggressive or stalking behaviors. * **DSM-5 Criteria:** For a diagnosis of Delusional Disorder, the delusion must persist for **at least 1 month**, and the patient’s global functioning is otherwise not markedly impaired. * **Management:** The primary treatment involves **Antipsychotics** (e.g., Risperidone) and psychotherapy to manage social consequences. * **Key Association:** It is often categorized under "Paranoid Disorders" in older texts but remains a classic example of a **non-bizarre delusion**.

Q: Which of the following statements is NOT true regarding delusional disorder?

Occurs at an early age. ### Explanation **Delusional Disorder** is characterized by the presence of one or more non-bizarre or bizarre delusions lasting for at least one month, without meeting the criteria for schizophrenia (e.g., no prominent hallucinations or disorganized behavior). **Why Option D is the correct answer (The "False" statement):** Unlike Schizophrenia, which typically presents in late adolescence or early adulthood, **Delusional Disorder usually occurs at a later age.** The mean age of onset is approximately **35 to 50 years** (middle to late adulthood). Therefore, the statement that it occurs at an early age is incorrect. **Analysis of Incorrect Options (Risk Factors for Delusional Disorder):** * **Option A (Early Immigration):** Migration is a well-documented risk factor. The stress of cultural displacement and perceived discrimination can trigger persecutory ideation. * **Option B (Social Isolation):** Individuals who are socially isolated or have avoidant personality traits are at a higher risk, as they lack social validation to "reality-check" their beliefs. * **Option C (Sensory Impairment):** Hearing or visual impairments (especially in the elderly) are significant risk factors. Sensory deficits can lead to misinterpretations of the environment, fostering suspiciousness and delusional thinking. **High-Yield Clinical Pearls for NEET-PG:** * **Core Feature:** Functioning is remarkably preserved; the patient often appears normal except when their specific delusional theme is touched upon. * **Common Types:** Persecutory (most common), Jealous (Othello syndrome), Erotomanic (De Clerambault syndrome), Somatic, and Grandiose. * **Gender:** Slightly more common in females. * **Treatment:** Difficult to treat due to lack of insight. **Atypical antipsychotics** are the first-line pharmacological treatment, often combined with psychotherapy (CBT).

Q: Schizophrenia is primarily considered a disorder of which of the following functions?

Thought. **Explanation:** **Schizophrenia** is fundamentally defined as a **disorder of thought**. While it is a complex syndrome affecting multiple domains, the core psychopathology lies in the disruption of the form, content, and stream of thought. This is clinically manifested through "Formal Thought Disorder" (e.g., loosening of associations) and "Delusions" (fixed, false beliefs), which are the hallmarks of the condition. **Analysis of Options:** * **A. Thought (Correct):** Schizophrenia is the prototypical "Thought Disorder." Eugen Bleuler’s "4 As" (specifically *Associative loosening*) and Schneider’s First Rank Symptoms (specifically *Delusional perception* and *Thought alienation*) emphasize that the primary pathology is the fragmentation of the thinking process. * **B. Mood:** Disorders of mood (e.g., Depression, Bipolar Disorder) are characterized by primary disturbances in affect. While Schizophrenia may involve "blunted affect," this is considered a secondary or negative symptom rather than the primary diagnostic feature. * **C. Perception:** While hallucinations (perceptual disturbances) are common in Schizophrenia, they are not universal or exclusive to it. The diagnostic weight in Schizophrenia leans more heavily toward the disorganized thought process. * **D. Cognition:** Cognitive deficits (memory, executive function) are significant in Schizophrenia and often determine long-term prognosis, but the disorder is traditionally classified by its psychotic thought disturbances. **High-Yield Clinical Pearls for NEET-PG:** * **Bleuler’s 4 As:** **A**ffective flattening, **A**utism, **A**mbivalence, and **A**ssociative loosening (the most important). * **Schneider’s First Rank Symptoms (FRS):** Includes thought withdrawal, insertion, and broadcasting (Thought Alienation). * **Prognosis:** "Good prognosis" factors include late onset, female sex, presence of mood symptoms, and identifiable triggers/stressors.

Q: Which of the following is true for schizophrenia?

It is a disorder of thought. **Explanation:** **Why Option A is Correct:** Schizophrenia is fundamentally classified as a **disorder of thought**. It involves disturbances in the **form** (e.g., loosening of associations, neologisms), **content** (e.g., delusions), and **stream** of thought. While it also affects perception (hallucinations), emotion (blunted affect), and behavior, the core psychopathology lies in the fragmentation of thought processes and a loss of contact with reality. **Why Other Options are Incorrect:** * **Option B (Split Personality):** This is a common layman’s misconception. "Split personality" refers to **Dissociative Identity Disorder (DID)**. The "schizo" (split) in schizophrenia refers to a "split from reality" or a fragmentation of mental functions (the "Sejunction" theory by Wernicke), not multiple personalities. * **Option C & D (Emotional Turmoil/Childhood Trauma):** While psychosocial stressors and trauma can act as **triggers** or contributing factors in genetically predisposed individuals (Stress-Diathesis Model), they are not the primary cause. Schizophrenia is a complex **neurodevelopmental disorder** with strong genetic and biological underpinnings (e.g., Dopamine hypothesis). **High-Yield Clinical Pearls for NEET-PG:** * **Schneider’s First Rank Symptoms (FRS):** These are diagnostic pillars and include audible thoughts (thought echo), voices arguing/commenting, and thought withdrawal/insertion/broadcast. * **Bleuler’s 4 A’s:** Fundamental symptoms include **A**ffective flattening, **A**mbivalence, **A**utism (social withdrawal), and **A**ssociation looseness. * **Neurobiology:** Associated with increased dopaminergic activity in the **mesolimbic pathway** (positive symptoms) and decreased activity in the **mesocortical pathway** (negative symptoms). * **Prognosis:** Good prognostic factors include late onset, female sex, presence of mood symptoms, and being married.

Q: Which is the first rank symptom described by Delusions?

Thought insertion. **Explanation:** **Kurt Schneider’s First Rank Symptoms (FRS)** are a group of specific symptoms used to diagnose Schizophrenia. These symptoms are characterized by a loss of ego boundaries, where the patient cannot distinguish between their own internal mental processes and external influences. **Why Thought Insertion is Correct:** Thought insertion is a classic **Delusion of Control/Passivity**. It is the belief that thoughts are being put into one’s mind by an external agency (e.g., "The government is planting ideas in my head via satellite"). Along with **thought withdrawal** and **thought broadcasting**, it forms the "Thought Alienation" triad, which is a core component of Schneider’s FRS. **Analysis of Incorrect Options:** * **A. Echolalia:** This is the automatic repetition of vocalizations made by another person. It is a feature of **Catatonia** or certain neurodevelopmental disorders, but it is not a First Rank Symptom. * **C. Autism:** In psychiatry, "Autistic thinking" (detachment from reality) is one of **Eugen Bleuler’s 4 A’s** of Schizophrenia, not a Schneiderian First Rank Symptom. * **D. Suicidal tendency:** While common in psychiatric disorders, this is a clinical risk factor and not a diagnostic symptom of any specific psychotic framework. **High-Yield Clinical Pearls for NEET-PG:** * **Schneider’s FRS Mnemonic (ABCD):** * **A**uditory Hallucinations (Third person, Running commentary, Echo/Gedankenlautwerden). * **B**eliefs (Delusional perception). * **C**ontrol (Passivity of affect, impulse, or volition). * **D**elusions of Thought (Insertion, Withdrawal, Broadcasting). * **Bleuler’s 4 A’s:** Ambivalence, Autism, Affective flattening, and Association looseness. * **Note:** FRS are no longer required for a diagnosis in DSM-5, but they remain highly relevant for exams and identifying "Schneiderian Schizophrenia."

Q: Which of the following is considered a Schneider's first-rank symptom?

Voices commenting on actions. **Explanation:** Kurt Schneider proposed **First-Rank Symptoms (FRS)** in 1959 to differentiate schizophrenia from other psychotic disorders. These symptoms are considered highly suggestive of schizophrenia in the absence of organic brain disease. **Why Option B is Correct:** **Voices commenting on one's actions** (Third-person auditory hallucinations) is one of the classic "Auditory Hallucinations" described by Schneider. In this symptom, the patient hears voices describing their movements or behaviors as they happen (e.g., "Now he is picking up the glass"). The other two specific auditory FRS are **voices arguing/discussing** and **thought echo** (Gedankenlautwerden). **Analysis of Incorrect Options:** * **A & C (Persecutory Delusion & Delusion of Guilt):** While these are common in schizophrenia and mood disorders, they are considered **Second-Rank Symptoms**. Schneider believed these delusions could occur in various psychiatric conditions and were not pathognomonic for schizophrenia. * **D (Incoherence):** This is a formal thought disorder. While it is a diagnostic criterion in DSM-5 and ICD-10, it is not part of Schneider’s original list of First-Rank Symptoms. **High-Yield Clinical Pearls for NEET-PG:** * **Mnemonic for FRS (ABCD):** * **A**uditory Hallucinations (Thought echo, 3rd person voices, running commentary). * **B**roadcasting of thoughts (and Thought Withdrawal/Insertion). * **C**ontrolled feelings/impulses/acts (Passivity phenomena/Made phenomena). * **D**elusional Perception (A normal perception followed by a private, highly significant, usually delusional conclusion). * **Note:** The presence of FRS is no longer mandatory for a diagnosis of schizophrenia in **DSM-5**, as they were found to be less specific than previously thought, though they remain high-yield for exams.

Q: Delusions in delirium are generally:

Transient. **Explanation:** Delirium is an acute neuropsychiatric syndrome characterized by a fluctuating course, altered consciousness, and global cognitive impairment. The correct answer is **Transient** because delusions in delirium are typically fleeting, poorly systematized, and fragmented. 1. **Why "Transient" is correct:** Unlike the fixed, well-organized delusions seen in Schizophrenia or Delusional Disorder, delusions in delirium lack stability. Because the patient’s level of consciousness and attention fluctuates throughout the day, their thought content remains disorganized and shifts rapidly. 2. **Why other options are incorrect:** * **Frightening:** While patients often experience fear due to visual hallucinations (zoopsia), the delusions themselves are not defined by being "frightening" as a diagnostic rule. * **Self-referential:** Ideas of reference are more characteristic of Schizophrenia or Mood Disorders with psychotic features. * **Nihilistic:** These are specific delusions (e.g., Cotard’s syndrome) where a patient believes they are dead or do not exist, typically associated with severe Psychotic Depression, not delirium. **High-Yield Clinical Pearls for NEET-PG:** * **Core Feature:** The hallmark of delirium is an **impairment of consciousness** (clouding of sensorium) and a **fluctuating** course (symptoms often worsen at night, known as "sundowning"). * **Hallucinations:** Visual hallucinations are much more common in delirium than auditory ones. * **EEG Finding:** Characteristically shows **generalized slowing** (except in Delirium Tremens, where there is low-voltage fast activity). * **Reversibility:** Delirium is usually secondary to an underlying medical condition (e.g., infection, electrolyte imbalance) and is reversible once the cause is treated.

Q: Which feature suggests schizophrenia rather than organic psychosis?

Third person auditory hallucination. **Explanation:** The distinction between functional psychosis (like Schizophrenia) and organic psychosis (due to medical conditions or substance use) is a high-yield topic in NEET-PG. **1. Why Option A is Correct:** **Third-person auditory hallucinations** (voices talking about the patient in the third person) and **running commentary** are considered **Schneiderian First Rank Symptoms (SFRS)**. These are highly characteristic of Schizophrenia. While not pathognomonic, their presence in a clear sensorium strongly points toward a functional psychotic disorder rather than an organic cause. **2. Why Incorrect Options are Wrong:** * **B. Split Personality:** This is a common layperson's misconception. "Split personality" refers to Dissociative Identity Disorder, not Schizophrenia. Schizophrenia involves a "splitting" of mental functions (thought, emotion, and behavior), not multiple identities. * **C. Visual Hallucinations:** These are the hallmark of **organic psychosis** (e.g., delirium, alcohol withdrawal, or head injury). While they can occur in schizophrenia, their presence should always prompt a clinician to rule out medical or neurological causes first. * **D. Altered Sensorium:** This refers to clouding of consciousness or disorientation. It is the defining feature of **Delirium (Organic Brain Syndrome)**. In Schizophrenia, the sensorium (orientation to time, place, and person) remains characteristically **clear**. **Clinical Pearls for NEET-PG:** * **Hallucinations:** Auditory = Most common in Schizophrenia; Visual/Tactile/Olfactory = Suggest Organic etiology. * **SFRS:** Includes audible thoughts (thought echo), voices arguing, voices commenting, and passivity phenomena. * **Age of Onset:** Schizophrenia typically starts in late teens to early 30s; new-onset psychosis in an elderly patient is almost always organic.

Q: Delusion of infidelity is seen in which of the following syndromes?

Othello syndrome. **Explanation:** **1. Correct Option: Othello Syndrome (A)** Othello syndrome, also known as **pathological jealousy** or **morbid jealousy**, is characterized by a persistent and false belief (delusion) that one’s spouse or partner is being unfaithful. It is a form of delusional disorder (jealous type). Patients often go to extreme lengths to find "evidence" of infidelity, such as checking phone logs, stalking, or interrogating their partner. It is frequently associated with chronic alcoholism and carries a high risk of domestic violence. **2. Incorrect Options:** * **De Clérambault Syndrome (B):** Also known as **Erotomania**. The patient (usually female) holds a delusional belief that another person, typically of higher social status or a celebrity, is deeply in love with them. * **Magnan Syndrome (C):** This refers to **Cocaine-induced psychosis**, specifically characterized by tactile hallucinations known as "formication" or "cocaine bugs" (the sensation of insects crawling under the skin). * **Cotard Syndrome (D):** Also known as **Walking Corpse Syndrome** or **Nihilistic delusion**. The patient believes they are dead, do not exist, or that their internal organs have rotted away. It is most commonly seen in severe psychotic depression. **Clinical Pearls for NEET-PG:** * **Capgras Syndrome:** The belief that a familiar person has been replaced by an identical-looking impostor (the most common "misidentification syndrome"). * **Fregoli Syndrome:** The belief that different people are actually a single person in disguise. * **Ekbom Syndrome:** Delusional parasitosis (belief that one is infested with parasites). * **Othello Syndrome** is most strongly linked with **Alcohol Dependence Syndrome**.
