Psychotic Disorders Practice Questions

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 - Note: The term "paranoid schizophrenia" is outdated (DSM-5, ICD-11); current classification uses "schizophrenia" with symptom specifiers.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**.

Q: Schizophrenia with the worst prognosis is which of the following?

Disorganized type. ***Disorganized type*** - This subtype, also known as **hebephrenic schizophrenia**, is characterized by prominent **disorganized speech**, **behavior**, and **flat or inappropriate affect**. - The combination of severe thought disorder and affective disturbance typically leads to a **poorer long-term outcome** and **greater functional impairment**. *Catatonic type* - Characterized by prominent psychomotor disturbances, such as **stupor**, **catalepsy**, **waxy flexibility**, mutism, or excessive motor activity. - While acute episodes can be severe, the long-term prognosis is generally considered better than the disorganized type, especially if treatment is initiated early. *Paranoid type* - This subtype is characterized by prominent **delusions** (often persecutory or grandiose) and **auditory hallucinations**, with relatively preserved cognitive function and affect. - Patients with paranoid schizophrenia often have a **better prognosis** and are more likely to achieve functional recovery compared to disorganized type. *Undifferentiated type* - This diagnosis is given when the criteria for the paranoid, disorganized, or catatonic types are not met, but prominent **positive (e.g., delusions, hallucinations)** and **negative (e.g., avolition, anhedonia)** symptoms of schizophrenia are present. - The prognosis varies widely and is not inherently worse than the disorganized type; it simply indicates that the clinical picture doesn't fit neatly into other defined subtypes.

Q: Which type of schizophrenia is characterized by prominent psychomotor disturbances such as waxy flexibility, stupor, or catatonic excitement?

Catatonic schizophrenia. ***Catatonic schizophrenia*** - **Catatonic schizophrenia** is distinguished by prominent **psychomotor disturbances**, including **waxy flexibility** (the ability to be molded into positions that are then maintained). - Other features include **stupor**, **posturing**, **echolalia**, **mutism**, and **negativism**, along with periods of excessive, purposeless motor activity. *Simple schizophrenia* - This type is characterized by a gradual and insidious onset of **negative symptoms**, such as apathy, anhedonia, and social withdrawal. - It lacks prominent positive symptoms like hallucinations, delusions, or the distinctive psychomotor symptoms seen in catatonia. *Hebephrenic schizophrenia* - Also known as **disorganized schizophrenia**, it is characterized by prominent **disorganized speech** and behavior, as well as flat or inappropriate affect. - While there may be some motor abnormalities, they do not typically manifest as the specific psychomotor features like waxy flexibility or stupor. *None of the options* - This option is incorrect because catatonic schizophrenia precisely describes the symptoms of increased psychomotor activity and waxy flexibility. - These features are classic diagnostic criteria for catatonic presentations within the schizophrenia spectrum.

Q: A patient presents with fixed, false beliefs about their partner's fidelity. What is the most likely diagnosis?

Delusional Disorder. ***Delusional Disorder*** - This condition is characterized by the presence of **non-bizarre delusions** (plausible in real life) that persist for at least one month, often involving themes such as jealousy, persecution, or grandiosity. - The patient's fixed, false beliefs about their partner's fidelity are a classic example of a **delusion of jealousy** (Othello syndrome). - According to DSM-5, the diagnosis requires the presence of delusions for at least one month, with no other symptoms of schizophrenia, and relatively preserved functioning apart from the impact of the delusion. *Schizophrenia* - Schizophrenia involves a broader range of psychotic symptoms, including **bizarre delusions**, hallucinations, disorganized thinking, and negative symptoms. - While delusions are present in schizophrenia, the absence of other symptoms like prominent **hallucinations** or disorganized speech makes this diagnosis less likely. *Brief psychotic disorder* - Brief psychotic disorder is characterized by the sudden onset of psychotic symptoms (delusions, hallucinations, disorganized speech) that last for **at least one day but less than one month**. - The key differentiator here is the **duration**: if symptoms persist beyond one month with only delusions present, delusional disorder is more appropriate. *Adjustment disorder* - Adjustment disorder is a stress-related condition characterized by emotional or behavioral symptoms that develop in response to a clearly identifiable stressor. - The symptoms are typically reactive and *do not involve psychotic features* like fixed, false beliefs (delusions).

Q: A patient with complaints of a deformed nose, despite reassurances from multiple plastic surgeons that there is no deformity, is most probably suffering from:

Delusional disorder. ***Body Dysmorphic Disorder (BDD) / Delusional Disorder (Somatic Type)*** - This is a **classic presentation of Body Dysmorphic Disorder (BDD)** characterized by preoccupation with a perceived defect in physical appearance that is **not observable or appears slight to others** - The nose is the **most common site of concern** in BDD - Patients typically seek reassurance from multiple specialists (plastic surgeons, dermatologists) despite objective evidence of no deformity - When the belief is held with **delusional intensity** (as in this case with multiple reassurances ignored), it can be classified as **delusional disorder, somatic type** - BDD is classified under Obsessive-Compulsive and Related Disorders in DSM-5 *Somatization disorder* - Involves **multiple medically unexplained physical symptoms** affecting various body systems over several years - Not characterized by a singular, fixed belief about a specific perceived physical defect - Patients present with numerous somatic complaints, not focused preoccupation with appearance *Hypochondriasis (Illness Anxiety Disorder)* - Characterized by **preoccupation with having or acquiring a serious illness** based on misinterpretation of bodily symptoms - The focus is on disease/illness, not appearance or physical defects - Different from concern about a perceived cosmetic deformity *OCD* - Involves **recurrent, intrusive thoughts (obsessions)** and **repetitive behaviors (compulsions)** performed to reduce anxiety - While BDD can have obsessive quality, this patient shows a fixed belief about deformity rather than ego-dystonic obsessions - No mention of compulsive rituals or behaviors in this case

Q: Which of the following hallucinations is pathognomonic of schizophrenia?

Auditory hallucinations giving running commentary. ***Auditory hallucinations giving running commentary*** - **Third-person auditory hallucinations**, particularly those giving a continuous descriptive commentary on the patient's actions, thoughts, or movements, are considered **pathognomonic of schizophrenia** within Schneider's first-rank symptoms. - These are distinguished from other types of auditory hallucinations by their specific content and the perspective from which they are perceived, indicating a fundamental disruption in self-perception and reality testing. *Auditory hallucinations commanding the patient* - **Command hallucinations** involve voices instructing the patient to perform specific actions and can occur in various psychiatric conditions, including other psychoses, mood disorders with psychotic features, and even non-psychotic states. - While significant and potentially dangerous, they are **not unique to schizophrenia** and therefore not pathognomonic. *Auditory hallucinations criticizing the patient* - **Critical auditory hallucinations** involve voices that demean, scold, or negatively evaluate the patient, contributing to distress and low self-esteem. - These are also **nonspecific** and can be found in a range of mental health conditions, including depression with psychotic features and bipolar disorder. *Auditory hallucinations talking to patient* - **Second-person auditory hallucinations**, where voices communicate directly with the patient in a conversational manner, are common in various psychotic disorders. - They are a general feature of psychosis and **do not specifically indicate schizophrenia** over other conditions; the *content* and *form* of the hallucination are crucial for differential diagnosis.

Q: The primary disturbance in schizophrenia is:

Formal Thought Disorder. ***Formal Thought Disorder*** - **Formal thought disorder** is considered the primary disturbance in schizophrenia, affecting the structure and organization of thought, leading to symptoms like **loosening of associations**, **tangentiality**, and **word salad**. - It underlies many of the other symptomatic manifestations of schizophrenia, influencing perception, belief, and behavior. *Hallucination* - **Hallucinations** are perceptual disturbances that occur in the absence of an external stimulus, most commonly auditory in schizophrenia. - While prominent in schizophrenia, hallucinations are a *symptom* arising from the underlying thought disorder, not the primary disturbance itself. *Illusion* - An **illusion** is a misinterpretation of an actual external stimulus. - Illusions are much less common in schizophrenia compared to hallucinations and are not considered a primary or defining feature of the disorder. *Psychomotor Retardation* - **Psychomotor retardation** involves a generalized slowing of physical and emotional reactions, and can be seen in conditions like depression or catatonia. - While it can occur in some forms of schizophrenia (e.g., catatonic type), it is not the primary or universal disturbance characterizing the disorder as a whole.
