Psychiatric Assessment and Diagnosis Practice Questions

Q: A 40-year-old female has been experiencing headaches for the past 6 months. Her investigations have been normal, and she has had several consultations without relief. She continues to believe she has a brain problem. What is the likely diagnosis?

Hypochondriasis. ### Explanation **Correct Option: D. Hypochondriasis** The clinical presentation describes a patient with a persistent preoccupation (lasting >6 months) with the fear or idea of having a serious disease (brain tumor/problem), despite normal investigations and medical reassurance. In **Hypochondriasis** (now classified under **Somatic Symptom and Related Disorders** in DSM-5 as Illness Anxiety Disorder), the core feature is the **misinterpretation of bodily symptoms**. The patient’s distress is not about the physical pain itself, but rather the *significance* of that pain (e.g., "This headache means I have a tumor"). **Analysis of Incorrect Options:** * **A & B (Acute Mania/Depression):** While mood disorders can have somatic components, they are primarily characterized by disturbances in affect, energy, and psychomotor activity. There is no evidence of elation, grandiosity, or pervasive low mood in this vignette. * **C (Psychogenic Headache):** This refers to a headache caused by emotional stress or psychological factors (e.g., Tension-type headache). However, the defining feature in this question is the patient’s **persistent belief** and refusal to accept medical reassurance, which points specifically to a psychiatric preoccupation rather than just the origin of the pain. **High-Yield NEET-PG Pearls:** * **Duration:** For a diagnosis of Hypochondriasis, symptoms must persist for at least **6 months**. * **Doctor Shopping:** These patients frequently undergo "doctor shopping" and multiple unnecessary investigations. * **Hypochondriasis vs. Somatization:** In Somatization, the focus is on the **symptoms** themselves (seeking relief from pain); in Hypochondriasis, the focus is on the **underlying disease** (fear of the diagnosis). * **Treatment:** Cognitive Behavioral Therapy (CBT) is the first-line psychological treatment. SSRIs are used if there is comorbid anxiety or depression.

Q: Unfamiliarity of familiar things is seen in which phenomenon?

Jamais vu. **Explanation:** The phenomenon described is **Jamais vu**, which is a disorder of memory and recognition. **1. Why Jamais vu is correct:** Jamais vu (French for "never seen") is the **illusion of unfamiliarity**. It occurs when a person encounters a situation, person, or place that is objectively familiar but feels completely new or strange. In psychiatry and neurology, it is classified as a **paramnesia** (distortion of memory). It is most commonly associated with **Temporal Lobe Epilepsy (TLE)**, where it serves as an aura, but can also occur in migraines or states of extreme fatigue. **2. Analysis of Incorrect Options:** * **A. Déjà vu:** This is the "illusion of familiarity." It is the feeling that a new, novel situation has been experienced before. It is the exact opposite of Jamais vu. * **C. Déjà entendu:** This refers to the "already heard" phenomenon—the illusion that a new sound or conversation has been heard previously. * **D. Déjà pensé:** This refers to the "already thought" phenomenon—the illusion that a new thought or idea has occurred to the person before. **3. Clinical Pearls for NEET-PG:** * **Localization:** Both Déjà vu and Jamais vu are strongly associated with the **Temporal Lobe** (specifically the hippocampus and parahippocampal gyrus). * **Differential Diagnosis:** While these can occur in healthy individuals (especially under stress), frequent occurrences should raise suspicion for **Complex Partial Seizures**. * **Capgras Syndrome:** Do not confuse Jamais vu with Capgras syndrome. In Capgras, the patient believes a familiar person has been replaced by an **imposter** (a delusional misidentification), whereas Jamais vu is a transient, subjective feeling of strangeness.

Q: All of the following are features of hallucinations, except:

Sensory organs are not involved. **Explanation:** Hallucinations are defined as **perceptions in the absence of an external stimulus**. To understand this question, one must distinguish between the *source* of the perception and the *experience* of it. **Why Option B is the correct answer:** The statement "Sensory organs are not involved" is **incorrect** (making it the right choice for an "except" question). While hallucinations are generated in the brain (often due to neurotransmitter imbalances like dopamine excess), the individual experiences them through their sensory pathways. For example, in auditory hallucinations, the primary auditory cortex is activated, and the patient "hears" the sound just as they would a real one. Therefore, the sensory system is fundamentally involved in the manifestation of the perception. **Analysis of other options:** * **Option A (Independent of will):** True. Hallucinations are involuntary; the observer cannot summon or dismiss them at will. * **Option C (Vividness):** True. A hallmark of a true hallucination is that it possesses the same force and clarity as a real perception (unlike imagery, which is faint). * **Option D (Absence of stimulus):** True. This is the core definition. If a stimulus were present but misinterpreted, it would be an **illusion**. **High-Yield Clinical Pearls for NEET-PG:** * **Hallucination vs. Pseudohallucination:** True hallucinations occur in **outer objective space**, while pseudohallucinations occur in **inner subjective space** (e.g., "voices inside my head"). * **Most Common Types:** Auditory hallucinations are most common in **Schizophrenia**, while visual hallucinations often suggest an **organic/medical etiology** (e.g., delirium, substance withdrawal). * **Hypnagogic vs. Hypnopompic:** Hallucinations while falling asleep (Hypna**g**ogic = **G**o to sleep) vs. waking up (Hypno**p**ompic = **P**op out of bed). These can occur in normal individuals or Narcolepsy.

Q: Which statement regarding hallucinations is FALSE?

Sensory organs are not involved in hallucinations.. **Explanation:** The correct answer is **C**. This statement is false because, by definition, hallucinations are perceptions that occur in the absence of an external stimulus but are processed by the brain as if the **sensory organs** were actually involved. While there is no external object, the individual "sees" with their eyes or "hears" with their ears; the experience is vivid and possesses the full force and impact of a real perception. **Analysis of Options:** * **Option A (False):** Hallucinations are characterized by a **lack of insight**. The patient perceives them as real and objective, not as products of their imagination (unlike pseudohallucinations). * **Option B (False):** True hallucinations are projected into the **external objective space** (e.g., a voice coming from the corner of the room), distinguishing them from imagery which occurs in internal subjective space. * **Option D (False):** This is the core definition of a hallucination. Unlike an **illusion** (which is a misinterpretation of a real stimulus), a hallucination occurs without any external stimulus. **Clinical Pearls for NEET-PG:** * **Hypnagogic vs. Hypnopompic:** Hallucinations while falling asleep (Hypna**go**gic = **Go**ing to sleep) vs. waking up (**P**ompic = **P**ost-sleep/ waking up). These can be normal but are also seen in Narcolepsy. * **Schizophrenia:** Most common type is **Auditory** (specifically third-person voices). * **Organic Brain Syndrome/Drug Withdrawal:** Most common type is **Visual**. * **Temporal Lobe Epilepsy:** Often associated with **Olfactory** hallucinations (Uncinate fits). * **Formication:** The sensation of insects crawling on the skin; common in Cocaine use ("Cocaine bugs") and Alcohol withdrawal.

Q: Delusion is not typically seen in which of the following conditions?

Anxiety disorders. **Explanation:** The core of this question lies in distinguishing between **Psychotic Disorders** and **Neurotic Disorders**. **1. Why Anxiety Disorders is the correct answer:** Anxiety disorders (such as GAD, Panic Disorder, and Phobias) are classified as **neurotic disorders**. In these conditions, **reality testing remains intact**. While patients may experience irrational fears or obsessions, they do not harbor fixed, false beliefs that are unshakable despite evidence to the contrary (delusions). If a patient with anxiety develops delusions, the diagnosis usually shifts toward a psychotic spectrum or a mood disorder with psychotic features. **2. Why the other options are incorrect:** * **Schizophrenia:** Delusions are a **hallmark symptom** (Criterion A) of schizophrenia. They are typically bizarre or persecutory and represent a primary disturbance of thought content. * **Mania:** In Bipolar Disorder (Manic episode), **delusions of grandeur** are common. Patients may believe they possess special powers, extreme wealth, or a divine identity. * **Depression:** In Severe Depressive Episodes, **mood-congruent delusions** (e.g., delusions of guilt, poverty, or nihilistic delusions/Cotard syndrome) can occur, classifying it as "Psychotic Depression." **Clinical Pearls for NEET-PG:** * **Definition:** A delusion is a fixed, false belief that is out of keeping with the patient’s social, cultural, and educational background. * **Insight:** Insight is typically **present** in anxiety disorders but **absent** in conditions where delusions occur. * **Nihilistic Delusions:** Most commonly associated with severe depression (Cotard’s Syndrome). * **Primary vs. Secondary:** Delusions in Schizophrenia are often primary (autochthonous), while in Mania/Depression, they are usually secondary to the prevailing mood.

Q: IQ level of intelligence 90-109 is classified as:

Normal. **Explanation:** The classification of Intelligence Quotient (IQ) is primarily based on the **Wechsler Adult Intelligence Scale (WAIS)**, which follows a normal distribution (bell curve) with a mean of 100 and a standard deviation of 15. 1. **Why the correct answer is right:** An IQ score of **90–109** is classified as **Average or Normal**. This range represents the middle of the bell curve, encompassing approximately 50% of the general population. Individuals in this range possess the cognitive abilities required for standard academic and occupational functioning. 2. **Analysis of incorrect options:** * **Borderline (IQ 70–79):** This is the "gray zone" between Intellectual Disability and Low Normal intelligence. These individuals often require some support but do not meet the criteria for Intellectual Disability (which starts below 70). * **Low Normal / Dull Normal (IQ 80–89):** This range is below average but still within the normal variation of the population. * **Superior (IQ 120–129):** This represents significantly above-average cognitive functioning. (Note: 110–119 is High Average, and >130 is Very Superior/Gifted). **High-Yield Clinical Pearls for NEET-PG:** * **Intellectual Disability (ID):** Defined as an IQ <70 along with deficits in adaptive functioning. * **Classification of ID (ICD-10):** * **Mild:** 50–69 (Educable; most common type) * **Moderate:** 35–49 (Trainable; can perform supervised tasks) * **Severe:** 20–34 (Poor verbal communication) * **Profound:** <20 (Requires total nursing care) * **Formula:** IQ = (Mental Age / Chronological Age) × 100. * **Flynn Effect:** The observed rise in average IQ scores over generations, necessitating periodic re-norming of tests.

Q: What is transvestism?

Wearing clothes of the opposite sex. **Explanation:** **Transvestism** (or Transvestic Disorder) is a type of paraphilia characterized by recurrent and intense sexual arousal from **cross-dressing** (wearing clothes of the opposite sex). In the context of psychiatric diagnosis (DSM-5/ICD-11), it is primarily seen in heterosexual males who experience sexual excitement while wearing female attire. It is important to distinguish this from gender dysphoria; individuals with transvestism generally do not wish to change their biological sex. **Analysis of Incorrect Options:** * **Option B (Frotteurism):** This involves the act of touching or rubbing one's genitals against a non-consenting person, typically in crowded places like buses or trains. * **Option C (Necrophilia):** This is a paraphilia characterized by sexual attraction to or sexual intercourse with corpses. * **Option D (Voyeurism):** This involves achieving sexual arousal by observing an unsuspecting person who is naked, disrobing, or engaging in sexual activity ("Peeping Tom"). **High-Yield Clinical Pearls for NEET-PG:** * **Dual-role Transvestism (ICD-10):** Wearing clothes of the opposite sex to enjoy a temporary sense of membership in that sex, but *without* sexual motivation or desire for permanent sex reassignment. * **Fetishistic Transvestism:** Cross-dressing specifically for sexual arousal (often involving specific fabrics like silk or lace). * **Demographics:** Almost exclusively reported in males. * **Treatment:** Behavioral therapy (Aversion therapy) and SSRIs (to reduce compulsive sexual urges) are commonly employed.

Q: A patient reports hearing music whenever their thumb is touched. This phenomenon is an example of what type of hallucination?

Reflex hallucination. ### Explanation **Correct Answer: A. Reflex hallucination** **Why it is correct:** A **reflex hallucination** occurs when a sensory stimulus in one modality (e.g., touch) triggers a hallucination in a completely different sensory modality (e.g., hearing). In this case, the tactile stimulus of touching the thumb "reflexively" provokes an auditory hallucination (music). This is a form of synesthesia-like pathological experience often associated with schizophrenia. **Why the other options are incorrect:** * **B. Functional hallucination:** This occurs when a real stimulus in one modality triggers a hallucination in the **same** modality. For example, hearing voices only when a tap is running (water noise triggers auditory hallucination). * **C. Visual hallucination:** This refers to seeing things that are not there. The question describes an auditory experience (music). * **D. Extracampine hallucination:** This is a hallucination that occurs outside the normal sensory field. For example, a patient "seeing" someone standing behind them or "hearing" a voice coming from another city. **High-Yield NEET-PG Pearls:** * **Reflex vs. Functional:** The key differentiator is the **modality**. Different modality = Reflex; Same modality = Functional. * **Hypnagogic vs. Hypnopompic:** Hallucinations while falling asleep (Gogic = Go to sleep) vs. waking up (Pompic = Pop out of bed). These can be normal but are also seen in Narcolepsy. * **Elementary Hallucinations:** Simple sounds (whistling, clicking) or flashes of light, often seen in organic brain disorders or epilepsy. * **Autoscopic Hallucination:** Seeing a double of oneself in the external space (phantom double).

Q: What is the new name for mental retardation in ICD-11?

Disorders of intellectual development. **Explanation:** The transition from ICD-10 to **ICD-11** brought significant changes in terminology to reduce stigma and align with modern clinical practices. The term "Mental Retardation" has been officially replaced by **Disorders of Intellectual Development**. **1. Why the correct answer is right:** In ICD-11, **Disorders of Intellectual Development** are classified under Neurodevelopmental Disorders. The diagnosis requires deficits in both intellectual functioning (usually confirmed by standardized testing, IQ < 70) and adaptive behavior (conceptual, social, and practical domains) originating during the developmental period. This shift emphasizes the developmental nature of the condition rather than just a "mental" deficit. **2. Why the other options are wrong:** * **Intellectual Disability (Option A):** This is the terminology used in the **DSM-5**. While commonly used in clinical practice and synonymous in meaning, it is not the specific term adopted by ICD-11. * **Mental Instability (Option C):** This is a vague, non-clinical term often used colloquially to describe mood swings or personality disorders; it has no place in formal psychiatric classification. * **Intellectual Deterioration (Option D):** This refers to a decline from a previously attained level of functioning, which is characteristic of **Dementia (Neurocognitive Disorders)**, whereas intellectual development disorders are present from birth or early childhood. **High-Yield Clinical Pearls for NEET-PG:** * **ICD-11 Code:** 6A00. * **Key Criteria:** Deficits in intellectual functions AND adaptive functioning. * **Severity Levels:** Still categorized as Mild, Moderate, Severe, and Profound, but based primarily on **adaptive functioning** rather than IQ scores alone. * **Most common cause:** Genetic (Trisomy 21/Down Syndrome is the most common chromosomal cause; Fragile X is the most common inherited cause).
