NEET-PG 2013 - Psychiatry NEET-PG Practice Questions and MCQs
Question 1301: In which socioeconomic strata is schizophrenia most commonly observed?
- A. Middle
- B. Upper
- C. Low (Correct Answer)
- D. Upper middle
Explanation: ***Low*** - Epidemiological studies consistently show a **higher prevalence of schizophrenia** in individuals from **lower socioeconomic strata**. - This association is explained by the "**social drift**" hypothesis, where individuals with schizophrenia experience a decline in social class due to the chronic and disabling nature of the illness, or the "**social causation**" hypothesis, which posits that adverse social conditions contribute to the development of the disorder. *Middle* - While individuals from all socioeconomic backgrounds can develop schizophrenia, it is **less common** compared to the lowest strata. - The middle socioeconomic group generally experiences **better access to resources** and support systems, which may mitigate some risk factors. *Upper* - Schizophrenia is **least common** in the upper socioeconomic strata. - Individuals in this group typically have **greater financial stability**, better living conditions, and access to high-quality healthcare, which might protect against environmental stressors. *Upper middle* - Similar to the middle and upper strata, the upper-middle class experiences a **lower prevalence of schizophrenia** compared to the low socioeconomic group. - This group often benefits from **good educational opportunities** and stable employment, reducing some of the psychosocial stressors associated with the disorder.
Question 1302: Which of the following is considered a poor prognostic factor for schizophrenia?
- A. Presence of depression
- B. Presence of stressor
- C. Early onset (Correct Answer)
- D. Female sex
Explanation: ***Early onset*** - An **earlier age of onset** (e.g., childhood or early adolescence) for schizophrenia is consistently associated with a **worse long-term prognosis**, including more severe symptoms, greater functional impairment, and a lower likelihood of full recovery. - This is thought to be due to the greater developmental disruption caused by the illness when it begins at a younger age. *Presence of depression* - While depression is common in schizophrenia, it is generally considered to be a **treatable co-occurring condition** rather than a primary poor prognostic factor for the core psychotic disorder itself. - Effective treatment for depression can actually **improve overall quality of life** and adherence to antipsychotic medication. *Presence of stressor* - The presence of a significant psychosocial stressor at the onset of schizophrenia is often associated with a **better prognosis**, as it suggests a more reactive and potentially remitting course. - This indicates that the illness might be more environmentally triggered and less intrinsically severe. *Female sex* - **Female sex** is typically associated with a **somewhat better prognosis** in schizophrenia, with a later age of onset and potentially less severe symptoms compared to males. - This may be influenced by hormonal factors and differences in social support networks.
Question 1303: Which of the following is considered a poor prognostic factor for schizophrenia?
- A. Poor premorbid adjustment (Correct Answer)
- B. Male sex
- C. Presence of depression
- D. Blunted affect
Explanation: **Poor premorbid adjustment** - **Poor premorbid adjustment**, indicated by difficulties in social, academic, or occupational functioning before the onset of psychosis, is a consistent predictor of a worse outcome in schizophrenia. - This suggests a more pervasive and entrenched neurodevelopmental vulnerability impacting the individual's ability to cope and integrate socially. *Blunted affect (negative symptom)* - While **blunted affect** is a negative symptom often associated with poorer outcomes than positive symptoms, it is typically considered a *symptom* of the illness rather than a primary prognostic *factor* like premorbid adjustment. - Its presence contributes to disability, but it is not as strong an independent prognostic indicator as the life trajectory prior to illness onset. *Male sex (generally poorer prognosis)* - **Male sex** is generally associated with an **earlier age of onset** and often a **more severe course** of schizophrenia. - However, compared to significant functional impairment before disease onset, it is not as strong an individual predictor of overall long-term prognosis. *Presence of depression (often associated with better outcomes)* - The **presence of depressive symptoms** in schizophrenia is often associated with a **better prognosis**. - This is because depressive features can sometimes indicate a more preserved capacity for emotional experience and insight, which can align with higher functioning.
Question 1304: Which of the following is not considered a core diagnostic criterion for schizophrenia according to DSM-5?
- A. Catatonia
- B. Hallucinations
- C. Disorganized speech
- D. Social withdrawal (Correct Answer)
Explanation: ***Social withdrawal*** - While **social withdrawal** is a common clinical feature and often reflects negative symptoms in schizophrenia, it is **not specifically listed** as one of the **five core diagnostic criteria (Criterion A)** in DSM-5. - The five core symptom domains are: delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms (diminished emotional expression or avolition). - Social withdrawal may be a manifestation of negative symptoms or part of **social/occupational dysfunction (Criterion B)**, but it is not itself a distinct core diagnostic criterion. *Catatonia* - **Catatonic behavior** (such as stupor, catalepsy, waxy flexibility, posturing, or mutism) is explicitly included as part of the **fourth core diagnostic criterion**: "Grossly disorganized or catatonic behavior." - This makes it one of the five primary symptom domains in **Criterion A** of DSM-5. - Note: "Catatonia" as a **specifier** (requiring 3+ out of 12 symptoms) is different from catatonic behavior as a core symptom. *Hallucinations* - **Hallucinations** (most commonly auditory, but can be visual, tactile, olfactory, or gustatory) are the **second core diagnostic criterion** in DSM-5. - At least **two of the five core symptoms** must be present, and hallucinations fulfill this requirement as a key **positive symptom**. *Disorganized speech* - **Disorganized speech** (formal thought disorder) is the **third core diagnostic criterion** for schizophrenia. - Characterized by **derailment, tangentiality, incoherence, or loose associations**, it reflects significant disruption in organized thinking and communication.
Question 1305: Which of the following is NOT considered one of Bleuler's fundamental symptoms of schizophrenia?
- A. Loosening of associations
- B. Affect disturbances
- C. Autism
- D. Delusions (Correct Answer)
Explanation: ***Delusions*** - **Delusions** are considered a **first-rank symptom** of schizophrenia according to Schneider, but not one of Bleuler's fundamental "4 A's". - Bleuler classified delusions as **accessory symptoms**, which are variable and not always present, unlike fundamental symptoms. *Loosening of associations* - This is one of Bleuler's **"4 A's"**, representing a disturbance in the logical flow of thought, leading to incoherent speech and fractured thinking. - Bleuler saw this as a core cognitive dysfunction in schizophrenia. *Affect disturbances* - This refers to **inappropriate affect** (e.g., laughing at a funeral) or **blunted/flattened affect**, which is another of Bleuler's "4 A's." - It signifies a disruption in the normal experience and expression of emotions. *Autism* - Bleuler's term **"autism"** (or autismus) refers to a pathological self-preoccupation, withdrawal from social interaction, and an immersion in one's own internal world. - This is also one of Bleuler's **"4 A's"**, highlighting a foundational disturbance in social engagement.
Question 1306: Which of the following is NOT a feature of neurosis?
- A. Symptoms cause subjective distress
- B. Contact with reality preserved
- C. Personality disturbances (Correct Answer)
- D. Insight is maintained
Explanation: ***Personality disturbances*** - While neurosis can cause significant distress and impact functioning, it does not typically involve **fundamental alterations in personality structure or identity**. - **Personality disorders**, not neuroses, are characterized by deeply ingrained, inflexible, and maladaptive patterns of perceiving, thinking, and behaving that deviate markedly from cultural expectations. *Symptoms cause subjective distress* - A core characteristic of neurosis is that the individual experiences significant **emotional suffering** and discomfort due to their symptoms, such as anxiety, phobias, or obsessions. - This **subjective distress** is often a primary motivator for seeking treatment. *Contact with reality preserved* - Individuals with neurosis maintain their ability to **distinguish between internal experiences and external reality**, unlike in psychosis where this distinction is lost. - They may understand that their fears or anxieties are irrational, but they are unable to control them. *Insight is maintained* - People with neurosis generally have some level of **awareness** that they have a problem or that their symptoms are unreasonable or excessive. - This **insight** allows them to recognize the need for help and engage in therapeutic processes.
Question 1307: Which of the following is not a feature of psychosis?
- A. Loss of insight
- B. Preserved contact with reality (Correct Answer)
- C. Personality disturbances
- D. Presence of delusions
Explanation: ***Preserved contact with reality*** - Psychosis is fundamentally characterized by a **loss of contact with reality**, making this option a defining non-feature of the condition. - Individuals experiencing psychosis often have profound difficulties distinguishing between what is real and what is not. *Loss of insight* - **Lack of insight** into one's own mental illness is a hallmark feature of psychosis, meaning the affected individual may not recognize their thoughts or perceptions as abnormal. - This symptom contributes to the difficulty in engaging individuals with psychosis in treatment. *Presence of delusions* - **Delusions** are fixed, false beliefs that are resistant to reason or evidence, and they are a core positive symptom of psychosis. - These beliefs are often bizarre and can significantly impair an individual's functioning and perception of reality. *Personality disturbances* - While not a primary diagnostic criterion, **personality disturbances** can be associated with psychotic disorders. - Changes in personality, mood, and behavior may occur as a result of the psychotic experience or the underlying illness.
Question 1308: Which of the following conditions does not typically involve delusions?
- A. Delirium
- B. Alcohol withdrawal
- C. OCD (Correct Answer)
- D. Schizophrenia
Explanation: ***OCD*** - **Obsessive-compulsive disorder** is characterized by recurrent, intrusive **thoughts (obsessions)** and repetitive **behaviors (compulsions)**, which the individual typically recognizes as irrational. - While patients with severe OCD may have **poor insight**, they generally do not experience **delusions**, which are fixed, false beliefs held despite evidence to the contrary. *Delirium* - **Delirium** is an acute, fluctuating disturbance of consciousness resulting from medical conditions or substance intoxication/withdrawal, often accompanied by **psychotic symptoms** including **delusions** and **hallucinations**. - The rapid onset and global cognitive impairment make **delusions** a common feature. *Schizophrenia* - **Schizophrenia** is a severe mental disorder characterized by **psychotic symptoms**, with **delusions** being one of the hallmark positive symptoms. - These **delusions** often include **persecutory**, **grandiose**, or **somatic themes**, among others. *Alcohol withdrawal* - Severe **alcohol withdrawal** can lead to **delirium tremens (DTs)**, which is associated with **psychotic symptoms** such as **delusions** and vivid **hallucinations** (often visual or tactile). - These **delusions** are often **persecutory** or referential in nature and contribute to the patient's fear and agitation.
Question 1309: Which of the following is NOT a symptom of nicotine withdrawal?
- A. Anxiety
- B. Increased heart rate (Correct Answer)
- C. Hyperhidrosis
- D. Weight gain
Explanation: ***Increased heart rate*** - **Increased heart rate** is NOT a symptom of nicotine withdrawal; rather, it is associated with **active nicotine use** due to nicotine's stimulant effects on the sympathetic nervous system. - During **nicotine withdrawal**, the heart rate typically **decreases or normalizes** as the body adjusts to the absence of nicotine's cardiovascular stimulation. - Nicotine acts as a sympathomimetic agent, causing tachycardia during use, but withdrawal does not produce increased heart rate. *Anxiety* - **Anxiety** is one of the most common and prominent symptoms of **nicotine withdrawal**. - As nicotine affects neurotransmitter systems (particularly dopamine, norepinephrine, and serotonin), cessation leads to neurochemical imbalances manifesting as anxiety, irritability, and restlessness. - This symptom typically peaks within the first week of cessation. *Hyperhidrosis* - **Hyperhidrosis** (excessive sweating) is actually a recognized symptom of **nicotine withdrawal**. - Increased sweating can occur as part of the autonomic nervous system dysregulation during the withdrawal period. - This is included among the physical withdrawal symptoms in standard diagnostic criteria. *Weight gain* - **Weight gain** is a well-documented and common consequence of **nicotine withdrawal**. - This occurs due to increased appetite, decreased metabolic rate (as nicotine's metabolic-enhancing effects cease), and behavioral substitution of smoking with eating. - Average weight gain is approximately 4-5 kg in the months following cessation.
Question 1310: Which of the following is true regarding the treatment of cocaine withdrawal symptoms?
- A. Fluoxetine
- B. Antidepressants
- C. No specific drug (Correct Answer)
- D. Benzodiazepines
Explanation: ***No specific drug*** - Currently, there is **no FDA-approved pharmacotherapy** for the treatment of cocaine withdrawal symptoms or for preventing relapse in cocaine dependence. - Management primarily focuses on **supportive care**, **psychotherapy** (cognitive behavioral therapy, contingency management), and addressing **co-occurring mental health disorders**. - Unlike alcohol or opioid withdrawal, cocaine withdrawal is not life-threatening and does not require specific medication. *Fluoxetine* - Fluoxetine is a **selective serotonin reuptake inhibitor (SSRI)** primarily used to treat depression and anxiety disorders. - While depression can be a symptom of cocaine withdrawal, fluoxetine has **not been shown to be effective** for reducing cocaine use or treating cocaine withdrawal specifically. - Multiple clinical trials have failed to demonstrate benefit for cocaine dependence treatment. *Antidepressants* - While various antidepressants (including desipramine, bupropion) have been investigated, there is **no strong evidence** to support their routine use as primary treatment for cocaine withdrawal or dependence. - Their effectiveness in this context is **limited and inconsistent** across studies. - They may be used to treat **co-occurring depressive disorders** but not as primary cocaine withdrawal treatment. *Benzodiazepines* - Benzodiazepines are primarily used to manage **acute anxiety and seizures** during withdrawal from GABAergic substances like **alcohol and sedatives**. - They are generally **not recommended** for cocaine withdrawal as cocaine withdrawal does not cause seizures or dangerous autonomic instability. - May be used only for **severe agitation** or **co-occurring alcohol withdrawal**, but carry their own dependence potential and do not address cocaine withdrawal itself.
