Q: In stupor catatonia, all are seen except -

Agitation. ***Agitation*** - **Stuporous catatonia** is characterized by a significant reduction or absence of motor activity and responsiveness, making **agitation**—increased motor activity—an unlikely feature. - In such a state, the patient is typically rigid, immobile, and unresponsive to external stimuli, which is the antithesis of agitation. *Catalepsy* - **Catalepsy** refers to a trance-like state with a loss of voluntary motion and active posturing, where the limbs maintain any position in which they are placed (waxy flexibility). - This is a hallmark feature of **catatonic stupor**, indicating a profound disturbance in motor control. *Mutism* - **Mutism** is the absence or profound reduction of speech, which is a common and defining feature of **catatonic stupor**. - Patients in a stuporous state typically do not speak or respond verbally to questions or commands. *Akinesia* - **Akinesia** is the absence of movement, or pronounced difficulty in initiating voluntary movements, which is a key component of **catatonic stupor**. - Patients exhibit severe motor retardation, often appearing frozen or rigid.

Q: Which of the following statements is NOT true about type 1 schizophrenia?

It has a poor prognosis.. ***It has a poor prognosis.*** - This statement is **NOT true** about type 1 schizophrenia, making it the correct answer to this question. - Type 1 schizophrenia is generally associated with a **better prognosis** and good response to antipsychotic medication. - It is characterized by the prominence of **positive symptoms**, which tend to be more responsive to treatment. *It is an acute illness.* - This statement is **TRUE** about type 1 schizophrenia, so it is not the answer. - Type 1 schizophrenia is often characterized by an **acute onset** of symptoms, particularly positive symptoms. - This acute presentation differentiates it from type 2, which typically has a more insidious onset. *Intellect is usually maintained.* - This statement is **TRUE** about type 1 schizophrenia, so it is not the answer. - In type 1 schizophrenia, **cognitive function**, including intellect, is usually better preserved compared to type 2 schizophrenia. - While some cognitive deficits may occur, they are generally less severe and less pervasive than in type 2. *It is characterized by negative symptoms.* - This statement is **FALSE** about type 1 schizophrenia, but it is not the best answer because the prognosis statement is more definitively incorrect. - Type 1 schizophrenia is primarily characterized by the predominance of **positive symptoms**, such as hallucinations, delusions, and disorganized thought. - **Negative symptoms** (e.g., apathy, anhedonia, alogia, blunted affect) are the hallmark of type 2 schizophrenia.

Q: Ganser syndrome is classified under which of the following disorders?

Dissociative disorder. ***Dissociative disorder*** - Ganser syndrome is characterized by a "passing-off" behavior, where the individual gives **approximate or nonsensical answers** to simple questions, often associated with other dissociative symptoms. - While historically difficult to classify, contemporary understanding places it within the spectrum of dissociative disorders due to its features of an altered state of consciousness and a detachment from reality. *OCD* - **Obsessive-compulsive disorder (OCD)** involves recurrent, intrusive thoughts (obsessions) and repetitive behaviors or mental acts (compulsions). - Ganser syndrome does not typically present with the classic symptom profile of obsessions and compulsions. *Conversion disorder* - **Conversion disorder** involves neurological symptoms (e.g., paralysis, blindness, seizures) that are not consistent with neurological disease and are often preceded by psychological stress. - While both involve psychological factors, Ganser syndrome is distinct in its presentation of "answers" that are close but incorrect, rather than physical symptoms. *Schizoid personality disorder* - **Schizoid personality disorder** is characterized by a pervasive pattern of detachment from social relationships and a restricted range of expression of emotions in interpersonal settings. - This disorder primarily affects social functioning and emotional expression, which is different from the specific cognitive and behavioral pattern seen in Ganser syndrome.

Q: Which neurotransmitter is believed to be increased in mania?

Increased dopamine. ***Increased dopamine*** - **Dopamine** is the primary neurotransmitter implicated in the pathophysiology of mania according to the **dopaminergic hypothesis** of mood disorders. - Increased dopaminergic activity in the **mesolimbic and mesocortical pathways** contributes to the core symptoms of mania including **euphoria**, **increased goal-directed activity**, **reduced need for sleep**, **psychosis**, and **impulsivity**. - Evidence includes: response to dopamine antagonists (antipsychotics) in treating mania, and dopamine agonists can precipitate manic episodes. - Studies using neuroimaging and CSF analysis support elevated dopamine activity during manic episodes. *Increased norepinephrine* - While norepinephrine is also increased in mania and contributes to **arousal**, **attention**, and **energy levels**, it is considered a secondary or contributory mechanism rather than the primary pathophysiological change. - The **catecholamine hypothesis** suggests both dopamine and norepinephrine are elevated, but dopamine plays the more central role in the characteristic manic symptoms. *Decreased dopamine* - Decreased dopamine is associated with **depression**, **Parkinson's disease**, and **negative symptoms of schizophrenia**, not mania. - Low dopamine leads to reduced motivation, anhedonia, psychomotor retardation, and lack of energy—the opposite of manic presentation. *Decreased norepinephrine* - Decreased norepinephrine is linked to **depressive states**, characterized by low energy, poor concentration, and reduced arousal. - This is directly contrary to the hyperarousal, excessive energy, and heightened activity seen in mania.

Q: What is the core feature required for diagnosing a manic episode?

Elevated mood. ***Elevated mood*** - The **DSM-5 criteria** for a manic episode explicitly state that an abnormally and persistently **elevated, expansive, or irritable mood** must be present for at least one week. - This core mood disturbance is what differentiates mania from other psychiatric conditions and is a prerequisite for diagnosis. *Grandiosity* - While **grandiosity** (inflated self-esteem or sense of importance) is a common associated symptom of a manic episode, it is not the sole diagnostic requirement. - It is one of several symptom criteria that must be present in addition to the mood disturbance for a diagnosis of mania. *Decreased appetite* - **Decreased appetite** is generally not a feature of a manic episode; in fact, individuals in a manic state often have an **increased appetite** or engage in impulsive eating due to lack of inhibition. - A decreased appetite is more commonly associated with depressive episodes. *Increased sleep* - **Increased sleep** is contrary to the typical presentation of a manic episode, where individuals often experience a **decreased need for sleep** and can function on very little sleep, feeling energized. - A significant reduction in the need for sleep is a characteristic symptom of mania, not an increase.

Q: Cyclothymia is classified as which type of mood disorder?

Bipolar mood disorder. ***Bipolar mood disorder*** - **Cyclothymia (Cyclothymic Disorder)** is classified under **Bipolar and Related Disorders** in both DSM-5 and ICD-11, making it part of the bipolar spectrum. - It is characterized by **chronic, fluctuating mood disturbances** lasting at least 2 years (1 year in children/adolescents) with numerous periods of hypomanic and depressive symptoms that do not meet full criteria for hypomanic or major depressive episodes. - The alternating, less severe mood swings share the fundamental **bipolar pattern** of mood elevation and depression, hence its classification under bipolar mood disorders. *Major depression* - **Major depressive disorder** is a unipolar mood disorder involving persistent feelings of sadness, loss of interest, and other depressive symptoms that significantly impair daily functioning, **without any episodes of mania or hypomania**. - Cyclothymia involves **mood instability with both elevated and depressed periods**, which distinguishes it from unipolar major depression. *Dysthymia* - **Dysthymia** (now termed **Persistent Depressive Disorder** in DSM-5) is characterized by chronic, low-grade depressive symptoms lasting at least 2 years, **without manic or hypomanic episodes**. - While both involve sub-threshold symptoms, cyclothymia includes periods of **hypomanic symptoms** (elevated mood, increased energy), which are absent in dysthymia. *Persistent mood disorder* - This is a broad, non-specific descriptive term rather than a formal diagnostic category in DSM-5 or ICD-11. - While cyclothymia is indeed a persistent condition, it is **specifically categorized under Bipolar and Related Disorders** due to the presence of both elevated (hypomanic) and depressed mood states.

Q: All are required to diagnose major depression except?

Nihilistic ideas. ***Nihilistic ideas*** - While nihilistic ideas (e.g., belief that life is meaningless or that nothing matters) can occur in severe depression, they are **not a mandatory diagnostic criterion** for major depressive disorder (MDD). - The diagnosis of MDD requires a specific number of core symptoms, and nihilistic ideation is not listed as one of them in diagnostic manuals like the DSM-5. *Depressed mood* - A **depressed mood** for most of the day, nearly every day, is one of the two **cardinal symptoms** required for a diagnosis of major depressive disorder. - The other cardinal symptom is anhedonia (loss of interest or pleasure). *Insomnia* - **Insomnia** (difficulty falling or staying asleep) or hypersomnia (sleeping excessively) is a common neurovegetative symptom of major depressive disorder and is one of the **nine diagnostic criteria**. - At least 5 of these 9 criteria must be present for a diagnosis, including at least one of the two cardinal symptoms. *Decreased concentration* - **Diminished ability to think or concentrate**, or indecisiveness, is another of the **nine diagnostic criteria** for major depressive disorder. - This cognitive symptom highlights the impact of depression on mental function beyond mood.

Q: What does the term 'Folie-à-deux' refer to?

Sharing of delusion. ***Sharing of delusion*** - **Folie-à-deux**, also known as **shared psychotic disorder**, describes a rare psychiatric syndrome in which a **delusional belief** is transmitted from one individual to another. - It typically occurs between two people in a close relationship, where one individual (the primary case) develops a delusion and the other person (the secondary case) subsequently adopts the same delusion. *Delusion of persecution* - A **delusion of persecution** is a specific type of delusion where an individual believes they are being harmed, harassed, or conspired against by others. - While it can be the content of a shared delusion in folie-à-deux, the term itself refers to the *type* of delusion, not the *sharing* mechanism. *Delusion of double* - "Delusion of double" is not a standard term for folie-à-deux. - This phrase might be confused with **delusional misidentification syndromes** (like Capgras syndrome where a person believes someone has been replaced by an identical impostor), but this is a different concept from shared psychotic disorder. *None of the options* - This option is incorrect because "sharing of delusion" accurately defines folie-à-deux.

Q: Which of the following is the most classic example of a delusion?

Othello syndrome. ***Othello syndrome*** - **Othello syndrome**, also known as **delusional jealousy**, is characterized by a *fixed, unfounded belief* that one's partner is being unfaithful. - This is a classic example of a **delusion** because it involves a **fixed, false belief** that is firmly held despite clear evidence to the contrary and is not amenable to logic or persuasion. - The syndrome demonstrates all core features of a delusion: **unshakeable conviction**, **imperviousness to contradictory evidence**, and **significant impact on behavior**. *De Clérambault's syndrome* - **De Clérambault's syndrome**, or **erotomania**, is a delusional disorder where an individual *believes another person, often of higher status, is in love with them*. - While this is also a classic example of a delusional disorder, **Othello syndrome** is more frequently cited in clinical teaching as the prototypical example of an isolated, circumscribed delusion. *Pyromania* - **Pyromania** is an **impulse control disorder** characterized by recurrent, deliberate fire-setting driven by tension or arousal. - It involves **behavioral impulsivity** and *not a fixed false belief*, thus it is not a delusion. *Kleptomania* - **Kleptomania** is another **impulse control disorder** characterized by recurrent failure to resist urges to steal objects not needed for personal use. - Like pyromania, it represents a **disorder of impulse control** rather than a disorder of thought content or belief system.

Q: The delusion that involves the belief that a familiar person has been replaced by someone else is known as?

Capgras syndrome. ***Capgras syndrome*** - This **delusional misidentification syndrome** is characterized by the belief that a familiar person (e.g., a spouse, child, or parent) has been replaced by an identical imposter. - It often occurs in individuals with **schizophrenia**, **dementia**, or following **brain injury**. *Cotard syndrome* - This syndrome involves a nihilistic delusion where the individual believes they are **dead**, do not exist, or have lost their organs or blood. - It is often associated with severe **depression**, psychosis, or neurological disorders. *Othello syndrome* - Also known as **delusional jealousy**, this involves the unfounded belief that one's partner is being unfaithful. - It is a **primary delusional disorder** but can also be seen in conditions like alcohol dependence or neurodegenerative diseases. *Fregoli syndrome* - This is another **delusional misidentification syndrome** where the person believes that different people are actually the same person in disguise. - It is the opposite of Capgras syndrome and may occur in **schizophrenia** or **organic brain disorders**.
