Psychotic Disorders Practice Questions

Q: Which of the following is not associated with stuporous catatonia?

Increased speech production. **Explanation:** **Catatonia** is a neuropsychiatric syndrome characterized by a cluster of motor, emotional, and behavioral abnormalities. It is broadly classified into two types: **Stuporous (Retarded)** and **Excited**. **Why "Increased speech production" is the correct answer:** Stuporous catatonia is defined by a state of marked psychomotor retardation. The hallmark features include **mutism** (little to no verbal response) and **stupor** (no psychomotor activity; no active relation to the environment). Therefore, "increased speech production" (logorrhea or pressure of speech) is diametrically opposed to the clinical presentation of stuporous catatonia. Increased speech is instead a feature of **Excited Catatonia** or Manic episodes. **Analysis of incorrect options:** * **Echolalia & Echopraxia:** These are "automatic obedience" or "mimicry" phenomena. Echolalia is the pathological repetition of another's words, and echopraxia is the imitation of another's movements. Both are classic features of catatonia (ICD-10/DSM-5 criteria). * **Rigidity:** This refers to motoric immobility where the patient maintains a stiff posture against all efforts to be moved. It is a core motor sign of the stuporous subtype. **High-Yield Clinical Pearls for NEET-PG:** * **Drug of Choice:** Benzodiazepines (specifically **Lorazepam**) are the first-line treatment (Lorazepam Challenge Test). * **Definitive Treatment:** Electroconvulsive Therapy (ECT) is highly effective, especially in malignant catatonia. * **Waxy Flexibility (Cerea Flexibilitas):** A classic sign where the patient maintains positions into which they are placed by the examiner. * **Gegenhalten (Paratonia):** Resistance to passive movement that is proportional to the strength of the stimulus. * **Malignant Catatonia:** A life-threatening form characterized by autonomic instability and hyperthermia (similar to Neuroleptic Malignant Syndrome).

Q: All of the following are positive features of Schizophrenia except?

Anhedonia. **Explanation:** In Schizophrenia, symptoms are broadly categorized into **Positive symptoms** (excess or distortion of normal functions) and **Negative symptoms** (diminution or loss of normal functions). **Why Anhedonia is the correct answer:** **Anhedonia** is defined as the inability to experience pleasure from activities usually found enjoyable. It is a classic **Negative symptom** of Schizophrenia, often grouped under the "5 A's" of negative symptoms (Affective flattening, Alogia, Anhedonia, Asociality, and Avolition). These symptoms are typically more resistant to traditional antipsychotic treatment and are associated with a poorer long-term prognosis. **Analysis of Incorrect Options:** * **Thought Disorder (A):** Specifically formal thought disorder (e.g., loosening of associations), is a **Positive symptom** representing a disorganized distortion of thinking. * **Visual Hallucination (C):** Hallucinations are sensory perceptions in the absence of external stimuli. They are hallmark **Positive symptoms**. While auditory hallucinations are most common in schizophrenia, visual ones also fall into this category. * **Delusion of Persecution (D):** Delusions are fixed, false beliefs. Persecutory delusions are the most common type in Schizophrenia and are classic **Positive symptoms**. **NEET-PG Clinical Pearls:** * **Positive Symptoms:** Mediated by increased dopamine in the **mesolimbic pathway**. They respond well to typical antipsychotics (D2 blockers). * **Negative Symptoms:** Mediated by decreased dopamine in the **mesocortical pathway**. They respond better to atypical antipsychotics (SDA). * **Schneider’s First Rank Symptoms (FRS):** These are all **Positive symptoms** (e.g., thought insertion, broadcasting, third-person hallucinations) used for diagnosis. Negative symptoms are *not* part of Schneider’s FRS.

Q: Which of the following is NOT one of Eugene Bleuler's 4 A's of schizophrenia?

Anhedonia. **Explanation:** Eugene Bleuler, a Swiss psychiatrist, coined the term "Schizophrenia" and identified four primary (fundamental) symptoms that characterize the disorder. These are famously known as **Bleuler’s 4 A’s**. **Why Anhedonia is the correct answer:** Anhedonia (the inability to feel pleasure) is a common negative symptom of schizophrenia, but it is **not** one of Bleuler’s original 4 A’s. It was later emphasized in different diagnostic frameworks, such as Schneider’s First Rank Symptoms or the DSM criteria for negative symptoms. **Analysis of the 4 A’s (Incorrect Options):** * **A - Association (Loosening of Association):** Refers to fragmented thought processes where ideas are disconnected and lack logical continuity. * **A - Affect (Inappropriate/Flattened Affect):** Refers to emotional responses that are either blunted or incongruent with the situation (e.g., laughing at a funeral). * **A - Autism:** Refers to social withdrawal and a preference for a private, internal fantasy world over external reality. * **A - Ambivalence:** (Though not listed as an option here, it is the 4th 'A') Refers to the simultaneous existence of contradictory feelings or impulses toward the same object or situation. **High-Yield Clinical Pearls for NEET-PG:** * **Bleuler vs. Schneider:** Bleuler focused on **fundamental symptoms** (the 4 A’s), whereas Kurt Schneider focused on **First Rank Symptoms (FRS)** (e.g., hallucinations, delusions), which are more useful for cross-sectional diagnosis. * Bleuler believed the 4 A's were present in every case of schizophrenia, regardless of the subtype. * **Mnemonic:** Remember **"4 A's"** = **A**ffect, **A**ssociation, **A**mbivalence, **A**utism.

Q: Poor prognosis of schizophrenia is associated with which of the following factors?

Predominance of negative symptoms. **Explanation:** The prognosis of schizophrenia is determined by a combination of clinical, social, and demographic factors. **Why "Predominance of Negative Symptoms" is correct:** Negative symptoms (e.g., apathy, anhedonia, poverty of speech, and social withdrawal) are strongly associated with a **poor prognosis**. These symptoms are often linked to structural brain changes (like ventricular enlargement), poor response to typical antipsychotics, and significant cognitive impairment. Unlike positive symptoms (hallucinations/delusions), which are often episodic and treatable, negative symptoms tend to be chronic and lead to long-term functional decline. **Analysis of Incorrect Options:** * **Female Sex:** Generally associated with a **better prognosis**. Females typically have a later age of onset, better premorbid social functioning, and better response to treatment compared to males. * **Presence of Depression:** While it increases suicide risk, the presence of affective symptoms (mood symptoms) is actually a **good prognostic factor**. It suggests a "Schizoaffective" picture, which typically has a better outcome than pure schizophrenia. * **Acute Onset:** An abrupt onset (triggered by a stressor) is a **good prognostic factor**. In contrast, an insidious (gradual) onset over years is associated with a poor outcome. **High-Yield Clinical Pearls for NEET-PG:** * **Best Prognostic Factor:** Good premorbid adjustment and presence of a clear precipitating stressor. * **Worst Prognostic Factor:** Early/Young age of onset (especially in males) and insidious onset. * **Family History:** A family history of **Mood Disorders** predicts a better prognosis, while a family history of **Schizophrenia** predicts a poorer one. * **Type I vs. Type II Schizophrenia:** Crow’s classification links Type II (Negative symptoms) with structural brain changes and poor treatment response.

Q: A 28-year-old female presents with complaints of reduced sleep and disorganized behavior for 9 months. She believes a camera is fixed behind her head that constantly follows her. Which of the following is the most likely diagnosis?

Paranoid schizophrenia. **Explanation:** The patient presents with **disorganized behavior** and a **delusion of being followed** (persecutory/bizarre delusion) persisting for **9 months**. According to ICD-11 and DSM-5 criteria, a diagnosis of Schizophrenia requires symptoms (such as delusions, hallucinations, or disorganized speech/behavior) to persist for at least 1 month (ICD) or 6 months (DSM), with significant social or occupational dysfunction. **Why Paranoid Schizophrenia is correct:** The presence of a complex delusion (camera fixed behind the head) combined with disorganized behavior and a chronic course (9 months) fits the classic profile of Schizophrenia. The "Paranoid" subtype is characterized by prominent delusions and/or auditory hallucinations without significant negative symptoms or catatonia at the forefront. **Why other options are incorrect:** * **Psychotic Depression:** Requires a primary mood disturbance (pervasive sadness, anhedonia) with mood-congruent delusions. There is no mention of depressed mood here. * **Delusional Disorder:** Characterized by non-bizarre delusions lasting ≥1 month. However, disorganized behavior and the "bizarre" nature of the camera delusion (physically impossible) point strongly toward Schizophrenia rather than Delusional Disorder. * **Insomnia:** This is merely a symptom (reduced sleep) and does not account for the psychotic features or behavioral changes. **NEET-PG High-Yield Pearls:** * **Duration Criteria:** Schizophreniform disorder ( 6 months). * **Schneider’s First Rank Symptoms (FRS):** Though no longer mandatory for diagnosis, delusions of being controlled or "passivity phenomena" are classic indicators of Schizophrenia. * **Prognosis:** Paranoid schizophrenia generally has a **better prognosis** and later age of onset compared to the Hebephrenic (disorganized) subtype.

Q: Which statement is true regarding the age and sex distribution of Schizophrenia?

Male sex is a poor prognostic factor.. **Explanation:** The epidemiology and prognosis of Schizophrenia are high-yield topics for NEET-PG. While the **incidence and prevalence** of Schizophrenia are roughly equal between genders, the clinical course and onset differ significantly. **1. Why Option C is Correct:** Male sex is considered a **poor prognostic factor**. On average, males have an earlier age of onset (15–25 years) compared to females (25–35 years). Males typically present with more **negative symptoms** (apathy, withdrawal), poorer premorbid adjustment, more structural brain abnormalities, and a less favorable response to neuroleptics. In contrast, females often have a better prognosis due to later onset and the protective effect of estrogen. **2. Why Other Options are Incorrect:** * **Option A:** The peak age of onset is **15–25 years for males** and **25–35 years for females**. Onset after age 45 is classified as Late-onset Schizophrenia and is relatively rare. * **Option B:** **Early onset is a poor prognostic factor.** The earlier the disease starts, the more it interferes with social/occupational development and the more likely it is to be associated with structural brain changes. * **Option D:** The **lifetime prevalence is equal** in both males and females (approximately 1%). Males are not "more prone" to the disease; they simply tend to develop it earlier and more severely. **High-Yield Clinical Pearls for NEET-PG:** * **Good Prognostic Factors:** Late onset, female sex, presence of mood symptoms (especially depression), positive symptoms (hallucinations/delusions), married status, and clear precipitating stressors. * **Poor Prognostic Factors:** Early onset, male sex, negative symptoms, family history of schizophrenia, and insidious onset. * **Bimodal Onset in Females:** Females show a second peak of incidence after age 40–45 (post-menopausal).
