Psychiatric Assessment and Diagnosis Practice Questions

Q: The phenomenon of déjà vu is best described as:

A sense that unfamiliar surroundings appear familiar.. **Explanation:** **Déjà vu** (French for "already seen") is a phenomenon of **paramnesia** where an individual experiences a distinct sense of familiarity when encountering a completely new or unfamiliar situation. It is a disturbance of memory recognition where the feeling of "knowing" occurs without a prior objective basis. **Analysis of Options:** * **Option B (Correct):** This accurately defines déjà vu. The person feels they have lived through the current, unfamiliar situation before. * **Option A (Incorrect):** This describes **Jamais vu** (French for "never seen"). It is the failure to recognize a familiar situation, leading to a sense of strangeness or novelty despite knowing the environment is familiar. * **Option C (Incorrect):** This refers to **Lethologica** or the "tip-of-the-tongue" phenomenon, which is a temporary failure of memory retrieval. * **Option D (Incorrect):** This describes **Depersonalization**, a dissociative symptom where an individual feels like an outside observer of their own body or mental processes. **Clinical Pearls for NEET-PG:** * **Localization:** Déjà vu is most commonly associated with the **Temporal Lobe**. * **Clinical Significance:** While it occurs in healthy individuals (often due to fatigue or stress), frequent or prolonged déjà vu is a classic "aura" or symptom of **Temporal Lobe Epilepsy (TLE)**. * **Related Terms:** * *Déjà entendu:* Feeling that something heard for the first time is familiar. * *Déjà pensé:* Feeling that a new thought has been thought before. * **Classification:** In psychiatry, these are categorized under **Disorders of Memory** (specifically Paramnesias).

Q: Reflex hallucination is a morbid variety of -

Synesthesia. **Explanation:** **Reflex Hallucination** is a morbid variety of **Synesthesia**. Synesthesia is a phenomenon where a stimulus in one sensory modality (e.g., hearing) triggers a real perception in another sensory modality (e.g., vision). In a reflex hallucination, a sensory stimulus in one field leads to a hallucinatory perception in another field. For example, a patient may experience a visual hallucination of a person standing next to them every time they hear a specific sound. This represents a "reflex" cross-activation between different sensory pathways. **Analysis of Incorrect Options:** * **Kinesthesia (A):** Refers to the perception of body movement and position. While there are "Kinesthetic hallucinations" (feeling like one is moving or flying), they do not involve the cross-modal sensory triggering seen in reflex hallucinations. * **Paresthesia (B):** This is a spontaneous abnormal sensation, such as "pins and needles," typically caused by peripheral nerve irritation. It is a neurological symptom rather than a complex psychiatric hallucination. * **Hyperesthesia (C):** Refers to an increased sensitivity to sensory stimuli (e.g., sounds appearing abnormally loud). It involves an intensity change within a single modality, not a cross-modal reflex. **NEET-PG High-Yield Pearls:** * **Functional Hallucination:** A stimulus in one modality triggers a hallucination in the *same* modality (e.g., hearing voices only when the tap is running). * **Reflex Hallucination:** A stimulus in one modality triggers a hallucination in a *different* modality (e.g., hearing a sound triggers a visual hallucination). * **Autoscopic Hallucination:** Seeing a double of oneself in external space (phantom double). * **Extracampine Hallucination:** A hallucination that occurs outside the normal sensory field (e.g., seeing someone behind your back).

Q: What is a false but firm belief about something which is not a fact?

Delusion. **Explanation:** The correct answer is **Delusion**. In psychiatry, a delusion is defined as a **fixed, false belief** that is firmly held despite incontrovertible evidence to the contrary and is not consistent with the patient's educational, social, or cultural background. It is a disorder of **thought content**. **Why the other options are incorrect:** * **Illusion:** This is a **misinterpretation** of a real external sensory stimulus (e.g., mistaking a rope for a snake in the dark). It is a disorder of perception, not belief. * **Hallucination:** This is a **perception in the absence of an external stimulus** (e.g., hearing voices when no one is speaking). Like illusions, these are disorders of perception. * **Obsession:** These are recurrent, persistent, and intrusive **thoughts, urges, or images** that cause marked anxiety. Unlike delusions, the patient usually recognizes them as irrational and products of their own mind (ego-dystonic). **Clinical Pearls for NEET-PG:** * **Primary vs. Secondary:** Primary delusions (autochthonous) arise suddenly without a preceding mental event, while secondary delusions are understandable in the context of other symptoms (e.g., a depressed patient believing they are bankrupt). * **Bizarre vs. Non-bizarre:** Bizarre delusions are clearly implausible (e.g., "aliens replaced my heart with a radio"), whereas non-bizarre delusions involve situations that could occur in real life (e.g., "the police are following me"). * **Overvalued Idea:** This is a bridge between normal belief and delusion; it is a solitary, abnormal belief that is not as "fixed" or "false" as a delusion but dominates the patient's life.

Q: The Rorschach test is primarily performed using which of the following?

Symmetric ink blots. **Explanation:** The **Rorschach Inkblot Test** is a classic **projective personality test** developed by Hermann Rorschach in 1921. It consists of **10 standardized cards** containing inkblots that are **bilaterally symmetrical**. 1. **Why Option A is Correct:** The test relies on the principle of projection. Because the inkblots are ambiguous and symmetrical, they do not represent specific objects. When a patient describes what they see, they "project" their unconscious thoughts, personality traits, and emotional functioning onto the stimuli. The symmetry provides a sense of "form" that helps the patient organize their perception while remaining vague enough to allow for varied interpretation. 2. **Why Options B, C, and D are Incorrect:** * **Asymmetric inkblots:** These are not used in the standardized Rorschach test; symmetry is a fundamental structural characteristic of the 10 official cards. * **Counting backwards/Subtractions:** These are components of the **Mini-Mental State Examination (MMSE)** or the **Mental Status Examination (MSE)**, specifically used to assess **attention, concentration, and calculation** (e.g., Serial 7s), rather than personality. **High-Yield Clinical Pearls for NEET-PG:** * **Card Composition:** Of the 10 cards, 5 are black and white (achromatic), 2 are black and red, and 3 are multicolored (polychromatic). * **Exner Scoring System:** This is the most widely used standardized system for interpreting Rorschach responses. * **Other Projective Tests:** * **Thematic Apperception Test (TAT):** Uses ambiguous pictures/scenes (Murray). * **Sentence Completion Test:** Uses unfinished stems. * **Draw-A-Person Test:** Used often in child psychiatry. * **Indication:** Useful for detecting thought disorders (like Schizophrenia) and uncovering defense mechanisms.

Q: Hallucinations experienced outside the sensory field limit are called?

Extracampine Hallucination. ### Explanation **Correct Option: A. Extracampine Hallucination** Extracampine hallucinations are false sensory perceptions that occur **outside the normal limits of the sensory field**. The term is derived from "extra" (outside) and "campus" (field). A classic clinical example is a patient who claims to see someone standing behind them while looking straight ahead, or hearing a voice coming from a city hundreds of miles away. These are distinct from other hallucinations because they defy the anatomical boundaries of the sense organ involved. **Analysis of Incorrect Options:** * **B. Kinesthetic Hallucination:** These involve the sensation of **bodily movement** or position. Patients may feel as if their limbs are moving, their body is vibrating, or they are being twisted, despite being stationary. * **C. Reflex Hallucination:** This is a synesthetic phenomenon where a real stimulus in one sensory modality triggers a hallucination in **another sensory modality**. For example, a patient hears a voice (auditory hallucination) only when they feel a toothache (somatic stimulus). * **D. Functional Hallucination:** These occur only when a real stimulus in the **same sensory modality** is present. For example, a patient hears voices only when they hear the sound of a running tap or a ticking clock. The real sound and the hallucination are perceived simultaneously. **High-Yield Clinical Pearls for NEET-PG:** * **Hypnagogic Hallucinations:** Occur while falling asleep (Normal/Narcolepsy). * **Hypnopompic Hallucinations:** Occur while waking up (Normal/Narcolepsy). * **Lilliputian Hallucination:** Seeing people or objects as much smaller than they are (Common in Delirium Tremens). * **Autoscopic Hallucination:** Seeing a "double" of oneself in the external space (Phantom mirror-image). * **Charles Bonnet Syndrome:** Visual hallucinations occurring in elderly patients with significant visual impairment (no psychiatric illness).

Q: A person is asked about his blood sugar level and responds, "Diabetics have sweet urine"... Urine and faeces are excreta." before finally stating his blood sugar level. What psychiatric phenomenon does this illustrate?

Circumstantiality. **Explanation:** The correct answer is **Circumstantiality**. This phenomenon is a formal thought disorder where the patient includes excessive, tedious, and unnecessary details before eventually reaching the goal of the conversation (the "point"). In this case, the patient provides irrelevant information about the nature of diabetes and excreta but ultimately answers the original question regarding his blood sugar level. **Analysis of Options:** * **Circumstantiality (Correct):** The key feature is that the patient **reaches the goal** of the conversation after a circuitous route. It is often seen in individuals with obsessive-compulsive traits, epilepsy, or intellectual disabilities. * **Tangentiality:** The patient moves from one topic to another that is related but **never returns to the original point** or answers the question. The "goal" is never reached. * **Flight of Ideas:** Characterized by rapid shifting between topics, usually linked by rhymes, puns, or environmental distractions (clanging/assonance). It is a hallmark of **Mania** and is typically associated with "pressure of speech." * **Loosening of Association (Knight’s Move Thinking):** A severe disruption where there is no logical connection between successive thoughts. The speech becomes incoherent to the listener. This is a core feature of **Schizophrenia**. **NEET-PG High-Yield Pearls:** * **Circumstantiality:** Goal is reached (Delayed). * **Tangentiality:** Goal is never reached. * **Derailment:** Another term for loosening of association; the "train of thought" leaves the track. * **Word Salad:** The most extreme form of loosening of association where even syntax is lost.

Q: A prisoner, when asked about the color of the sky, answered it as pink. This symptom is characteristic of which of the following?

Ganser syndrome. **Explanation:** The correct answer is **Ganser syndrome** (Option B). This condition is characterized by the production of **approximate answers** (vorbeireden), where the patient provides answers that are clearly wrong but indicate that the question was understood. For example, calling the sky "pink" or saying a cow has five legs. **Why Ganser Syndrome is Correct:** Ganser syndrome is a dissociative disorder (historically classified as a factitious disorder) most commonly observed in **prison populations** (hence the term "Prison Psychosis"). The classic triad includes: 1. **Approximate answers** (the hallmark feature). 2. Clouding of consciousness. 3. Somatic conversion symptoms or hallucinations. **Analysis of Incorrect Options:** * **A. Othello Syndrome:** Also known as pathological jealousy, it is a delusional belief that one's partner is being unfaithful. * **C. De Clerambault Syndrome:** Also known as Erotomania, it is a delusion where the patient believes that another person (usually of higher social status or a celebrity) is in love with them. * **D. Ekbom’s Syndrome:** Also known as Delusional Parasitosis, it is the fixed, false belief that one is infested with insects or parasites under the skin. **High-Yield Clinical Pearls for NEET-PG:** * **Vorbeireden:** The German term for "talking past the point" or giving approximate answers. * **Demographics:** Most common in males and forensic/prison settings. * **Differential Diagnosis:** Must be distinguished from **malingering**, where the patient consciously fakes symptoms for secondary gain (e.g., avoiding trial). In Ganser syndrome, the process is considered largely unconscious/dissociative.

Q: The Halstead Reitan battery includes all of the following except:

Constructional praxis. The **Halstead-Reitan Neuropsychological Battery (HRNB)** is a comprehensive set of tests used to assess the location and effects of brain damage. It evaluates various cognitive and sensorimotor functions. **Explanation of the Correct Answer:** **Option B (Constructional praxis)** is the correct answer because it is **not** a subtest of the Halstead-Reitan Battery. Constructional praxis (the ability to draw or assemble 2D or 3D objects) is typically assessed using the **Luria-Nebraska Neuropsychological Battery** or specific tests like the Bender-Gestalt Test. **Explanation of Incorrect Options:** * **A. Finger oscillation (Finger Tapping Test):** A core HRNB subtest that measures motor speed and coordination by having the patient tap a lever as fast as possible with the index finger. * **C. Rhythm (Seashore Rhythm Test):** A subtest assessing auditory perception and sustained attention where the patient must differentiate between pairs of rhythmic patterns. * **D. Tactual performance:** A subtest where the patient is blindfolded and asked to place blocks into a formboard. It assesses tactile perception, motor coordination, and spatial memory. **High-Yield Facts for NEET-PG:** * **Other HRNB Subtests:** Category Test (abstract reasoning), Speech Sounds Perception Test, and Trail Making Test (Part A and B). * **Purpose:** It is primarily used to differentiate between organic brain damage and functional psychiatric disorders. * **Luria-Nebraska vs. Halstead-Reitan:** While HRNB is more quantitative and time-consuming, the Luria-Nebraska Battery is more qualitative and takes less time to administer. * **Frontal Lobe Assessment:** The Wisconsin Card Sorting Test (WCST) is the gold standard for executive function/frontal lobe assessment, often tested alongside HRNB concepts.
