Psychotic Disorders Practice Questions

Q: What is the medical term for the phenomenon where an individual perceives a double or duplicate of themselves?

Autoscopy. ***Autoscopy*** - **Autoscopy** is a dissociative phenomenon where an individual perceives a vision of their own body projected outside themselves. - It often involves the sensation of seeing a **double** or **duplicate** of oneself from a different spatial perspective. *Capgras syndrome* - **Capgras syndrome** is a delusional misidentification syndrome where a person believes that a close relative or friend has been replaced by an identical impostor. - It does not involve seeing oneself, but rather perceiving others as duplicates or impostors. *Fregoli delusion* - The **Fregoli delusion** is a rare delusional misidentification syndrome in which the affected person believes that different people are in fact a single person in disguise, shifting appearance or identity. - This involves seeing other people as disguised versions of a known individual, not seeing a double of oneself. *Cotard delusion* - **Cotard delusion** (also known as walking corpse syndrome) is a rare mental illness in which the affected person holds the delusional belief that they are dead, do not exist, are putrefying, or have lost their blood or internal organs. - This delusion specifically involves beliefs about one's own non-existence or loss of bodily parts, rather than seeing a double of oneself.

Q: In which condition is erotomania most commonly observed?

Delusional disorder. ***Delusional disorder*** - Erotomania (De Clérambault's syndrome) is **classically and most commonly** associated with **Delusional Disorder, Erotomanic Type**. - This condition is characterized by a **non-bizarre delusion** that another person, usually of higher social status, is in love with the patient. - In delusional disorder, the erotomanic delusion is the **primary and defining feature**, typically lasting at least **1 month** without other prominent psychotic symptoms. - The patient maintains functioning in other areas of life apart from the impact of the delusion. *Bipolar mania* - While **psychotic features** can occur in severe manic episodes, erotomania is **not a characteristic** delusion of mania. - Manic delusions typically involve **grandiose themes** (special powers, wealth, identity), **persecutory content**, or ideas of reference. - Erotomania, when it occurs in bipolar disorder, is **rare** and not the most common presentation. *Neurosis* - **Neurosis** is an outdated term referring to non-psychotic mental disorders characterized by distress without loss of contact with reality. - Erotomania is a **psychotic symptom** (a delusion), indicating a break from reality, and is therefore not characteristic of neurosis. *Obsessive compulsive disorder* - **OCD** is characterized by recurrent, intrusive thoughts (obsessions) and repetitive behaviors (compulsions). - The patient typically recognizes obsessions as **irrational** and experiences them as ego-dystonic. - Erotomania is a **fixed, false belief** (delusion) held with absolute conviction, not an unwanted intrusive thought, making it fundamentally different from OCD.

Q: Which of the following is a negative symptom of schizophrenia?

Alogia (poverty of speech). ***Alogia (poverty of speech)*** - **Alogia** refers to a reduction in the **fluency and productivity of speech**, which is a classic **negative symptom** of schizophrenia indicating a *loss* or *absence* of normal functions. - Negative symptoms are characterized by deficits in normal emotional responses or other thought processes. *Hallucination* - **Hallucinations** are perceptual experiences that occur in the absence of an external stimulus, most commonly **auditory** in schizophrenia. - They are considered **positive symptoms** because they represent an *addition* or *distortion* of normal functions. *Delusion* - A **delusion** is a fixed, false belief that is not amenable to change in light of conflicting evidence, such as **persecutory** or **grandiose delusions**. - Delusions are also categorized as **positive symptoms** as they involve an *exaggeration* or *distortion* of normal thought content. *Motor hyperactivity* - **Motor hyperactivity** involves excessive or uncontrolled body movements and is not a typical symptom of schizophrenia. - While schizophrenia can involve **psychomotor agitation**, this is distinct from generalized hyperactivity and is not a core negative symptom.

Q: The syndrome characterized by an elaborate delusion that the patient is passionately loved by another person is also known as:

De Clérambault's syndrome. ***De Clérambault's syndrome*** - Also known as **erotomania**, this syndrome is characterized by the delusional belief that one is passionately loved by another person, often someone of higher social status. - Patients with this syndrome may go to great lengths to communicate with or even stalk the object of their delusion, interpreting any response as confirmation of their belief. *Ekbom's syndrome* - Also known as **delusional parasitosis**, where the patient believes they are infested with parasites (insects, worms, etc.), despite no medical evidence. - This often leads to self-mutilation as they try to remove the perceived parasites. *Othello syndrome* - This is a delusional disorder characterized by the **delusional belief of infidelity** by a spouse or partner, without any substantiating evidence. - It often leads to obsessive surveillance, accusations, and controlling behaviors, driven by intense jealousy. *Querulous paranoia* - This term refers to a type of paranoia where individuals feel that they have been **treated unjustly or wronged** and relentlessly seek to rectify these perceived injustices. - They are often seen as litigious or constantly complaining, characterized by a persistent and intense sense of grievance and a tendency to challenge authority or established systems.

Q: The worldwide lifetime prevalence of schizophrenia is best estimated as?

1%. ***1%*** - This value represents the widely accepted **lifetime prevalence** of schizophrenia across diverse populations and cultures. - While exact figures can vary slightly based on study methodology (0.7-1.0%), **1%** is the standard estimate provided in most psychiatric textbooks and epidemiological studies. - This means approximately 1 in 100 people will develop schizophrenia during their lifetime. *2.50%* - This figure is generally too high for the global lifetime prevalence of schizophrenia. - While other mental health conditions (such as depression or anxiety disorders) may have higher prevalence rates, schizophrenia is typically less common. *5%* - This percentage significantly overestimates the prevalence of schizophrenia. - Such a high rate would indicate a far more common disorder than observed clinically and epidemiologically. *10%* - A 10% lifetime prevalence rate for schizophrenia is exceptionally high and not supported by global epidemiological data. - This figure would imply that schizophrenia is one of the most common psychiatric disorders, which is not the case.

Q: Which of the following is NOT considered one of Schneider's first-rank symptoms?

Elation. ***Elation*** - **Elation** is a mood state characterized by intense joy, excitement, and a sense of well-being, commonly associated with bipolar disorder or mania. - It is **not** included in Schneider's first-rank symptoms, which are specific psychotic phenomena strongly suggestive of schizophrenia. *Auditory hallucinations* - **Auditory hallucinations** are a core first-rank symptom, specifically including: - **Voices commenting** on one's actions - **Voices arguing** or discussing the patient in the third person - **Thought echo** (audible thoughts) - These specific types of auditory hallucinations are highly indicative in Schneider's criteria for schizophrenia. *Thought insertion* - **Thought insertion** is a classic first-rank symptom where the patient believes that thoughts are being put into their mind by an external force or agency. - Along with **thought withdrawal** (thoughts being removed) and **thought broadcasting** (thoughts being made known to others), this belongs to the category of **disorders of thought possession**. - These are pathognomonic features in Schneider's framework. *Passivity phenomenon* - **Passivity phenomena** (also known as experiences of influence or control) involve the feeling that one's body, movements, emotions, or impulses are being controlled by an external force. - These include **made feelings**, **made impulses**, **made acts**, and **somatic passivity**, all of which are classic first-rank symptoms. - The patient experiences their will or actions as being taken over by an alien force.

Q: Delusions of control, persecution, and self-reference are seen in:

Schizophrenia. ***Schizophrenia*** - Hallmarks of **schizophrenia** (particularly presentations with predominantly positive symptoms) include bizarre and highly organized delusions, such as **delusions of control**, persecution, and self-reference, often accompanied by auditory hallucinations. - These symptoms disrupt daily functioning and are typically chronic, distinguishing it from other delusional disorders by its pervasive impact and additional psychotic features. - Note: The term "paranoid schizophrenia" is outdated (DSM-5, ICD-11); current classification uses "schizophrenia" with symptom specifiers. *Delusional disorder* - Characterized by **non-bizarre delusions**, meaning they could conceivably occur in real life, such as being followed or poisoned. - Lacks other symptoms of psychosis seen in schizophrenia, like hallucinations, disorganized speech, or negative symptoms. - Delusions are typically more circumscribed and less bizarre than in schizophrenia. *Bipolar disorder* - Primarily defined by episodes of **mania** and **depression**, with mood swings being the dominant feature. - Psychotic symptoms, if present, are usually **mood-congruent** and occur during severe manic or depressive episodes, not as persistent, bizarre delusions. *Generalized anxiety disorder* - Involves **persistent and excessive worry** about various aspects of life, accompanied by physical symptoms like restlessness, fatigue, and difficulty concentrating. - Does not involve delusions or other psychotic symptoms; the anxiety is rooted in reality-based concerns, however exaggerated.

Q: Which of the following is considered the prototypical major psychotic disorder?

Schizophrenia. ***Schizophrenia*** - Schizophrenia is often considered the **prototypical major psychotic disorder** due to its characteristic presentation of **positive symptoms** (hallucinations, delusions, disorganized thought), **negative symptoms** (avolition, anhedonia), and **cognitive deficits**. - It is a chronic and severe mental disorder that affects how a person thinks, feels, and behaves, leading to significant functional impairment. *Bipolar disorder with psychotic features* - This disorder primarily involves **mood disturbances** (manic and depressive episodes), with psychotic symptoms occurring specifically during severe mood episodes. - While it can involve psychosis, the **mood dysregulation** is the defining feature, differentiating it from disorders where psychosis is primary. *Delusional disorder* - Delusional disorder is characterized by the presence of **non-bizarre delusions** for at least one month, without the other prominent psychotic symptoms (e.g., hallucinations, disorganized speech) common in schizophrenia. - The **relative absence of other positive and negative symptoms** distinguishes it from schizophrenia. *Schizoaffective disorder* - Schizoaffective disorder involves a continuous period during which there is an uninterrupted illness where a **major mood episode (manic or depressive) is concurrent with Criterion A of schizophrenia**, and delusions or hallucinations have been present for at least two weeks in the absence of a major mood episode. - Its diagnosis requires the co-occurrence of prominent **mood episodes** with psychotic symptoms, distinguishing it from schizophrenia where psychosis is the core feature without necessarily prominent mood episodes.

Q: Characteristic hallucination of schizophrenia is -

Auditory hallucinations giving running commentary. **Auditory hallucinations giving running commentary** - **Third-person auditory hallucinations**, such as *running commentaries* or *voices discussing the patient in the third person*, are considered highly characteristic of **schizophrenia**, particularly a **first-rank symptom**. - These types of hallucinations are distinct from simple voices and often involve multiple voices or a narrative describing the patient's actions or thoughts. *Auditory hallucinations commanding the patient* - While *command hallucinations* can occur in **schizophrenia**, they are not considered as diagnostically characteristic as *third-person commentaries or discussions*. - *Command hallucinations* can also be seen in other psychiatric conditions, including **bipolar disorder** and **severe depression**. *Auditory hallucinations criticizing the patient* - *Critical or pejorative hallucinations* can be present in **schizophrenia**, but they are not as specific to the diagnosis as third-person voices. - These types of hallucinations can also be a feature of **mood disorders** with psychotic features. *Auditory hallucinations talking to patient* - *Second-person auditory hallucinations* where voices speak directly *to* the patient are common in many psychotic disorders, including **schizophrenia**. - However, they lack the specific classic feature of *third-person commentary* or discussion, which is more indicative of **schizophrenia**.
