Psychotic Disorders Practice Questions

Q: A 45-year-old man with a history of schizophrenia presents with flat affect, alogia, and avolition. Which of the following best describes his symptoms?

Negative symptoms. ***Negative symptoms*** - **Flat affect**, **alogia** (poverty of speech), and **avolition** (lack of motivation) are classic examples of negative symptoms in schizophrenia. - These symptoms represent a **reduction or absence of normal functions** and are often more disabling and harder to treat than positive symptoms. *Positive symptoms* - These symptoms involve an **excess or distortion of normal functions**, such as **hallucinations**, **delusions**, and disorganized thought or behavior. - The patient's presentation of flat affect, alogia, and avolition does not include these exaggerated or distorted experiences. *Cognitive symptoms* - **Cognitive symptoms** involve difficulties with attention, memory, executive functions (e.g., planning, problem-solving), and processing speed. - While common in schizophrenia, the described symptoms (flat affect, alogia, avolition) do not primarily fall under the cognitive domain. *Affective symptoms* - **Affective symptoms** relate to disturbances in mood, such as **depression**, **anxiety**, or **irritability**. - While emotional blunting (flat affect) is a negative symptom, the term "affective symptoms" typically refers to broader mood disorders, which are not explicitly described here.

Q: A 45-year-old man believes that he has been receiving secret messages through the television for the past year. He is otherwise functioning well and has no other psychiatric symptoms. What is the most likely diagnosis?

Delusional disorder. ***Delusional disorder*** - The presence of a **fixed, false belief** (receiving secret messages) lasting over a month, without other significant psychiatric symptoms or functional impairment, is characteristic of **delusional disorder**. - In this case, the patient is "otherwise functioning well" and has "no other psychiatric symptoms," pointing away from more pervasive psychotic disorders. *Schizophrenia* - Schizophrenia typically involves a broader range of symptoms, including **disorganized thought and speech**, **negative symptoms** (e.g., flat affect, anhedonia), and significant functional impairment, none of which are described here. - While delusions are a core feature of schizophrenia, they are usually accompanied by other psychotic symptoms and a decline in overall functioning. *Major depressive disorder with psychotic features* - This diagnosis would require prominent symptoms of a **major depressive episode**, such as depressed mood, anhedonia, and vegetative symptoms, alongside psychotic features. - The patient is described as "otherwise functioning well" and having "no other psychiatric symptoms," ruling out a primary mood disorder. *Bipolar disorder* - Bipolar disorder involves episodes of both **mania/hypomania** and **depression**, often with psychotic features occurring during severe mood episodes. - The patient's presentation of isolated delusions without mood cycling or the full symptom constellation of either manic or depressive episodes does not fit bipolar disorder.

Q: Which of the following statements is not true regarding delusional disorder?

Usually false. ***Usually false*** ✓ Correct Answer - This statement is **NOT TRUE** because delusions are **by definition always false beliefs**, not "usually false" - Delusions are **fixed false beliefs** that are firmly held despite evidence to the contrary - Saying "usually false" suggests they could sometimes be true, which contradicts the fundamental definition of a delusion - A true belief, no matter how unusual, is **not a delusion** by psychiatric criteria *Held with some conviction* - This is TRUE - Delusional disorder is characterized by the presence of **non-bizarre delusions** held with strong conviction - Patients do not recognize their beliefs as problematic and will **defend their delusional ideas** when challenged *Not easily amenable to reasoning* - This is TRUE - A key feature of delusional disorder is the patient's **resistance to logical argument** or conflicting evidence - This inflexibility is a hallmark of **delusional thinking**, distinguishing it from overvalued ideas or obsessions *Occurs at a later age* - This is TRUE - Delusional disorder typically has a **later age of onset** compared to schizophrenia - Often appearing in **middle to late adulthood** (40-49 years), distinguishing it from disorders that manifest in late adolescence or early adulthood

Q: A 39-year-old male patient presents with waxy flexibility, negativism and rigidity. Most probable diagnosis is?

Stuporous catatonia. ***Stuporous catatonia*** - **Waxy flexibility**, **negativism**, and **rigidity** are classic symptoms of catatonia, specifically indicating the stuporous presentation where there is a marked decrease in reactivity to the environment. - In this subtype, the patient often exhibits features such as **immobility**, mutism, and fixed postures, alongside the mentioned symptoms. *Excitatory catatonia* - Characterized by **psychomotor agitation**, restlessness, and sometimes violent behavior, which is contrary to the reduced reactivity seen in the patient. - Patients with excitatory catatonia may present with **purposeless motor activity** and impulsivity, along with other catatonic features. *Paranoid schizophrenia* - Primarily defined by prominent **delusions of persecution** or grandeur and **auditory hallucinations**. - While catatonic features can sometimes occur in schizophrenia, they are not the hallmark symptoms; the described features are more directly indicative of catatonia itself. *None of the options* - This is incorrect because the constellation of symptoms (waxy flexibility, negativism, rigidity) clearly points to a specific and well-recognized clinical syndrome, which is stuporous catatonia. - The symptoms provided are classic for a recognized psychiatric condition, making an "all of the above" or "none of the above" option unlikely if a specific diagnosis fits perfectly.

Q: Which type of persistent delusional disorder is characterized by the belief that one is being persecuted?

Delusion of persecution. ***Delusion of persecution*** - This is a core feature of **persecutory delusional disorder**, where the individual firmly believes they are being harmed, harassed, or conspired against by others. - The belief is **fixed** and **unshakeable**, despite evidence to the contrary. *Delusion of reference* - This involves a false belief that ordinary events, objects, or people in the environment have a particular and unusual meaning specifically directed at oneself. - It differs from persecution in that the emphasis is on **personal significance** rather than active harm or conspiracy. *Delusion of jealousy* - Characterized by the **unfounded belief** that one's partner is being unfaithful, often leading to surveillance and confrontation. - This is a specific type of delusional disorder, but it does not primarily involve a global sense of being persecuted. *Delusion of grandeur* - This involves an exaggerated belief in one's own **importance, power, knowledge, or identity**. - It contrasts with persecution, where the individual feels threatened rather than inflated in self-perception.

Q: A woman firmly and persistently believes that her husband is cheating on her, despite any evidence to the contrary, and she disapproves of accepting any proof given in her husband's support. The other family members do not support her belief. This is an example of-

Delusion. ***Delusion*** - A **delusion** is a **fixed, false belief** that is not amenable to change in light of conflicting evidence. - The woman's persistent belief about her husband's infidelity, despite evidence to the contrary and disagreement from family members, fits the diagnostic criteria for a delusion. - This scenario specifically describes a **jealous delusion (Othello syndrome)**, where a person falsely believes their partner is unfaithful without any reasonable basis. - Key features: **firmly held**, **evidence-resistant**, **not shared by others** (non-bizarre delusion). *Illusion* - An **illusion** is a **misinterpretation of a real external stimulus**. - Example: Seeing a rope in dim light and thinking it's a snake. - In this case, there is no misperception of a real sensory stimulus; rather, it's a false belief held without basis in reality. *Hallucination* - A **hallucination** is a **sensory perception in the absence of an external stimulus**. - Examples include hearing voices when no one is speaking, or seeing objects that aren't present. - The woman is not experiencing false sensory perceptions; she is holding a fixed false belief about her husband's actions. *Perversion* - **Perversion** refers to a **deviation from what is considered normal**, often used in the context of sexual behavior or moral corruption. - This term does not describe a psychotic symptom or cognitive disorder like a delusion. - Not relevant to the clinical presentation of fixed false beliefs in psychiatric disorders.

Q: Which of the following is not one of Eugene Bleuler's 4As?

Anhedonia. ***Anhedonia*** - **Anhedonia** is the inability to experience pleasure, often seen in major depressive disorder and schizophrenia, but it is not one of **Bleuler's original 4 As**. - **Bleuler's criteria** focused on fundamental symptoms of schizophrenia related to thought, feeling, and social interaction, not specifically the capacity for pleasure. *Autism* - **Autism** (Bleuler's concept of autism, referring to a withdrawal into a private world) is one of **Bleuler's 4 As**. - It describes the **self-absorption** and detachment from reality often observed in schizophrenia. *Affect* - **Affect** (specifically disturbance of affect, such as **blunted** or **inappropriate affect**) is one of **Bleuler's 4 As**. - This symptom refers to the **emotional responses** of an individual, which are often disorganized or mismatched with the context in schizophrenia. *Ambivalence* - **Ambivalence** (the coexistence of opposing thoughts, emotions, or attitudes toward the same object or situation) is one of **Bleuler's 4 As**. - It describes the **simultaneous presence of contradictory feelings** often seen in schizophrenia, such as loving and hating the same person at the same time.

Q: Catatonia is most commonly associated with which of the following mental disorders?

Schizophrenia. ***Schizophrenia*** - Catatonia is a severe neuropsychiatric syndrome characterized by profound psychomotor disturbance. It is **most commonly associated with schizophrenia and other psychotic disorders**. - Catatonia in schizophrenia can present with symptoms like **immobility**, **mutism**, **waxy flexibility**, **posturing**, **negativism**, and **stupor**. - Approximately **10-35%** of patients with schizophrenia may exhibit catatonic features during their illness, making it the most frequent psychiatric association. - DSM-5 recognizes catatonia as a specifier that can occur with schizophrenia spectrum disorders, where it remains most prevalent. *Major Depressive Disorder* - While catatonia can occur in mood disorders including major depressive disorder, it is **less common** than in schizophrenia and psychotic disorders. - When catatonia occurs in MDD, it indicates a **severe episode** and requires urgent treatment, often with benzodiazepines or ECT. - Catatonia in mood disorders accounts for a significant but smaller proportion of cases compared to psychotic disorders. *Specific Phobia* - **Specific phobias** are anxiety disorders characterized by an intense, irrational fear of a specific object or situation. - They do not involve **psychomotor disturbances** or other symptoms associated with catatonia. *Obsessive-Compulsive Disorder* - **Obsessive-compulsive disorder (OCD)** is characterized by recurrent, intrusive thoughts (obsessions) and repetitive behaviors (compulsions). - OCD does not present with **catatonic symptoms**; its motor features (compulsions) are driven by anxiety reduction, not the profound psychomotor dysfunction seen in catatonia.

Q: What psychiatric disorder is characterized by delusions of infidelity towards a spouse?

Othello syndrome. ***Othello syndrome*** - **Othello syndrome**, also known as **delusional jealousy**, is characterized by a **fixed, irrational belief** that one's partner is being unfaithful, despite a lack of evidence. - Individuals with this syndrome may engage in **excessive monitoring**, interrogations, and even violence to "prove" the infidelity. *Chronic alcohol use disorder* - While **chronic alcohol abuse** can sometimes contribute to paranoia or jealousy, it is not a psychiatric disorder primarily defined by **delusions of infidelity**. - Alcohol-related jealousy typically subsides with sobriety, unlike the persistent nature of Othello syndrome. *Stockholm syndrome (hostage bonding)* - **Stockholm syndrome** involves a psychological phenomenon where hostages develop a **psychological bond** with their captors during traumatic situations. - It is unrelated to delusions about a partner's infidelity. *Clerambault's syndrome (erotomania)* - **Clerambault's syndrome**, or **erotomania**, is a delusional disorder where an individual believes another person, often of higher status, is **madly in love with them**. - This is the opposite of delusional jealousy and involves a belief in being loved, not betrayed.

Q: Which of the following statements is true regarding delusional disorder?

Held with absolute conviction. ***Held with absolute conviction*** - This is the **BEST ANSWER** as it describes a **core diagnostic criterion** for delusions in delusional disorder per DSM-5/ICD-11. - Delusions are defined as **fixed, false beliefs held with absolute conviction** despite clear evidence to the contrary. - This unwavering certainty is what distinguishes delusions from overvalued ideas or normal beliefs. - This statement captures the fundamental **nature and defining characteristic** of the disorder itself. *More commonly occurs in middle to late adulthood* - This statement is **factually TRUE** - delusional disorder typically has onset between ages 40-55 (middle to late adulthood). - However, this describes **epidemiological data** (when it occurs), not a defining feature of the disorder. - While accurate, it is less fundamental than the absolute conviction which is a **diagnostic criterion**. *Often not amenable to reasoning* - This statement is also **factually TRUE** - patients with delusional disorder cannot be reasoned out of their false beliefs. - However, this is a **consequence** of the absolute conviction, not the primary defining feature. - The inability to respond to reasoning stems from the unwavering belief system. *Occurs at early age* - This is **FALSE** - delusional disorder is rare in early age. - Typical onset is in **middle to late adulthood** (ages 40-55), not childhood or adolescence. - Early onset would be atypical for this disorder.
