Psychotic Disorders Indian Medical PG Practice Questions and MCQs
Practice Indian Medical PG questions for Psychotic Disorders. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Psychotic Disorders Indian Medical PG Question 1: Which of the following is a validated screening tool for alcohol use disorder?
- A. AUDIT
- B. CAGE questionnaire
- C. SADQ
- D. All of the options (Correct Answer)
Psychotic Disorders Explanation: ***CAGE questionnaire and AUDIT***
- Both **CAGE** and **AUDIT** are widely validated screening tools specifically designed for alcohol use disorder [1].
- **CAGE** is a brief 4-item tool focusing on **C**ut down, **A**nnoyed, **G**uilty, and **E**ye-opener - ideal for quick screening in clinical settings [1].
- **AUDIT** (Alcohol Use Disorders Identification Test) is a comprehensive 10-item tool assessing consumption patterns, drinking behaviors, and alcohol-related problems.
- AUDIT is considered the **gold standard** for screening and can assess risk levels and severity.
*Why not SADQ alone?*
- **SADQ** (Severity of Alcohol Dependence Questionnaire) is primarily a **severity assessment tool**, not a screening tool.
- It is a 20-item instrument used to measure the **degree of alcohol dependence** in individuals already identified with alcohol problems.
- While valuable for treatment planning, SADQ is more detailed and designed for assessment rather than initial screening [1].
- However, all three tools are validated and used in alcohol use disorder evaluation - CAGE and AUDIT for screening, SADQ for severity assessment.
Psychotic Disorders Indian Medical PG Question 2: At which receptor is the primary action of antipsychotic medications required?
- A. M, muscarinic
- B. 5HT4 serotonergic
- C. D1 dopaminergic
- D. D2 dopaminergic (Correct Answer)
Psychotic Disorders Explanation: ***D2 dopaminergic***
- The **antipsychotic effects** of typical (first-generation) antipsychotics are primarily mediated through **D2 receptor blockade** [1].
- Blocking D2 receptors in the **mesolimbic pathway** helps reduce positive symptoms of psychosis like hallucinations and delusions [2].
*M, muscarinic*
- **Muscarinic receptor blockade** is a common adverse effect of some antipsychotics, leading to anticholinergic side effects such as **dry mouth** and **blurred vision**, rather than their primary therapeutic action.
- This action does not directly contribute to the antipsychotic effect.
*D1 dopaminergic*
- While D1 receptors are involved in dopamine signaling, they are **not the primary target** for the antipsychotic action of most drugs [1].
- Some atypical antipsychotics may affect D1 receptors, but it's secondary to their D2 antagonism and serotonin modulation.
*5HT4 serotonergic*
- **Serotonin receptors (5HT)**, particularly 5HT2A, are important targets for atypical (second-generation) antipsychotics.
- However, 5HT4 receptors are **not a primary target** for the antipsychotic effects, and 5HT2A blockade modulates dopamine release, which is still connected to the D2 hypothesis.
Psychotic Disorders Indian Medical PG Question 3: Which of the following is not a Cluster A personality disorder?
- A. schizoid
- B. schizotypal
- C. paranoid
- D. anankastic (Correct Answer)
Psychotic Disorders Explanation: ***Anankastic***
- **Anankastic personality disorder**, also known as **obsessive-compulsive personality disorder (OCPD)**, is classified under **Cluster C** personality disorders.
- Cluster C disorders are characterized by anxious, fearful thinking or behavior, which differentiates them from the odd or eccentric behaviors of Cluster A.
*Schizoid*
- **Schizoid personality disorder** is a **Cluster A** personality disorder, characterized by a pervasive pattern of detachment from social relationships and a restricted range of expression of emotions in interpersonal settings.
- Individuals with schizoid personality disorder typically show no desire for close relationships, including those with family members.
*Schizotypal*
- **Schizotypal personality disorder** is a **Cluster A** personality disorder, characterized by pervasive patterns of social and interpersonal deficits marked by acute discomfort with, and reduced capacity for, close relationships, as well as by cognitive or perceptual distortions and eccentricities of behavior.
- These individuals may have odd beliefs or magical thinking that is inconsistent with cultural norms.
*Paranoid*
- **Paranoid personality disorder** is a **Cluster A** personality disorder, characterized by a pervasive distrust and suspiciousness of others, such that their motives are interpreted as malevolent.
- Individuals with this disorder often believe that others are exploiting, harming, or deceiving them, even without sufficient basis.
Psychotic Disorders Indian Medical PG Question 4: A young patient with schizophrenia is resistant to treatment with conventional antipsychotic medications. Which drug is most preferred?
- A. Haloperidol
- B. Olanzapine
- C. Clozapine (Correct Answer)
- D. Risperidone
Psychotic Disorders Explanation: ***Clozapine***
- **Clozapine** is the drug of choice for **treatment-resistant schizophrenia** or patients who are **intolerant to conventional antipsychotics**.
- Its unique efficacy often comes with a risk of **agranulocytosis**, requiring regular **blood monitoring**.
*Olanzapine*
- While an effective **atypical antipsychotic**, it is not specifically indicated for **treatment-resistant cases** in the same way as clozapine.
- It carries a risk of significant **metabolic side effects**, such as weight gain and dyslipidemia.
*Haloperidol*
- This is a **first-generation (conventional) antipsychotic** and would be unsuitable for a patient described as **intolerant to conventional antipsychotics**.
- It is associated with a high incidence of **extrapyramidal symptoms (EPS)** and **tardive dyskinesia**.
*Risperidone*
- As an **atypical antipsychotic**, it is a good first-line option but is not typically reserved for **treatment-resistant schizophrenia** or those with conventional antipsychotic intolerance.
- It has a higher propensity for **hyperprolactinemia** compared to other atypical antipsychotics.
Psychotic Disorders Indian Medical PG Question 5: 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
Psychotic Disorders 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.
