Cognitive-Behavioral Therapy for Eating Disorders Indian Medical PG Practice Questions and MCQs

Question 1: Diagnostic criteria for Bulimia nervosa are all EXCEPT

A. Lack of control over eating behaviour
B. Self induced vomiting
C. Presence of other psychiatric disorders (Correct Answer)
D. Binge eating

Explanation: ***Presence of other psychiatric disorders*** - While psychiatric comorbidities like depression, anxiety, and substance abuse are **extremely common** in individuals with bulimia nervosa, they are **not a diagnostic criterion** for the disorder. - The DSM-5 diagnosis of bulimia nervosa focuses specifically on **eating behaviors** (binge eating), **compensatory mechanisms** (purging/non-purging), and the impact on self-evaluation, not on the presence of co-occurring mental health conditions. - This is the correct answer as it is **NOT** a diagnostic criterion. *Lack of control over eating behaviour* - This is a **core diagnostic criterion** of bulimia nervosa. - Individuals must experience a sense of **lack of control** over eating during binge episodes (feeling unable to stop eating or control what or how much they are eating). - This feeling of loss of control during binges is essential for diagnosis. *Self induced vomiting* - This is a **diagnostic criterion** as one of the inappropriate compensatory behaviors used to prevent weight gain after binge eating. - Other compensatory behaviors include misuse of laxatives, diuretics, enemas, fasting, or excessive exercise. - At least one type of compensatory behavior must occur regularly (average of once weekly for 3 months). *Binge eating* - This is a **fundamental diagnostic criterion** involving eating an amount of food that is definitely larger than what most people would eat in a similar period under similar circumstances. - Must occur in a discrete time period (e.g., within any 2-hour period) with a sense of lack of control. - Binge episodes must occur, on average, at least once a week for 3 months for diagnosis.

Question 2: A 16-year-old girl has intense cravings for food and consumes large amounts of it, followed by purging behaviors. What is the most likely diagnosis?

A. Anorexia nervosa
B. Bulimia nervosa (Correct Answer)
C. Major depressive disorder
D. Binge eating disorder

Explanation: ***Bulimia nervosa*** - **Bulimia nervosa** is characterized by recurrent episodes of **binge eating** (consuming large amounts of food with a sense of lack of control), followed by inappropriate **compensatory behaviors** such as self-induced vomiting, laxative abuse, or excessive exercise. - The patient's presentation of "intense cravings for food," consuming "large amounts," and "purging behaviors" directly aligns with DSM-5 diagnostic criteria for bulimia nervosa. - Peak onset is typically in **adolescence and early adulthood**, and it is more common in females. *Anorexia nervosa* - **Anorexia nervosa** is primarily characterized by **restriction of energy intake** leading to significantly low body weight, intense fear of gaining weight, and disturbance in body image. - While the binge-eating/purging subtype of anorexia exists, the defining feature is **persistent restriction** and significantly **low body weight**, which is not mentioned in this clinical scenario. *Major depressive disorder* - **Depression** is a mood disorder with persistent sadness, anhedonia, and neurovegetative symptoms. - While depression commonly co-occurs with eating disorders and may cause appetite changes, the specific cyclical pattern of **binge eating followed by compensatory purging** is not a characteristic feature of depression itself. *Binge eating disorder* - **Binge eating disorder** involves recurrent episodes of consuming large amounts of food with a sense of lack of control, accompanied by marked distress. - The key distinguishing feature is the **absence of regular compensatory behaviors** (purging, excessive exercise, fasting) that are present in bulimia nervosa.

Question 3: Best therapy suited to teach daily life skills to a child with intellectual disability:

A. Applied Behavior Analysis (ABA) (Correct Answer)
B. Cognitive Behavioral Therapy (CBT)
C. Social skills training
D. Self-instructional training

Explanation: **Applied Behavior Analysis (ABA)** - **ABA** is a highly structured, evidence-based therapy that focuses on teaching specific skills by breaking them down into smaller steps and using **positive reinforcement**. - It is particularly effective for children with intellectual disabilities in acquiring **adaptive daily living skills**, communication, and social behaviors. *Cognitive Behavioral Therapy (CBT)* - **CBT** primarily targets changing negative thought patterns and behaviors, requiring a level of abstract reasoning that may be challenging for children with significant intellectual disabilities. - While it can be adapted, its core methods rely on cognitive processes that might not be the most direct approach for teaching basic daily life skills to a mentally challenged child. *Social skills training* - **Social skills training** focuses specifically on improving social interactions and communication within social contexts. - While important for overall development, it is a subcomponent of broader skill development and may not directly address all aspects of **daily living skills** in a comprehensive manner. *Self-instructional training* - **Self-instructional training** involves teaching individuals to guide themselves through tasks using internal speech or self-talk, which relies on a child's ability to internalize and follow complex verbal instructions. - This approach might be too cognitively demanding for a child with significant developmental delays when the primary goal is mastering basic, functional daily life skills.

Question 4: Bulimia nervosa is treated with

A. Clozapine
B. Reserpine
C. Pimozide
D. Escitalopram (Correct Answer)

Explanation: ***Escitalopram*** - **SSRIs** like escitalopram are considered first-line pharmacological treatment for **bulimia nervosa**, especially when combined with **psychotherapy**. - They help reduce the frequency of **binge-eating** and **purging** episodes by modulating serotonin levels. *Clozapine* - This is an **atypical antipsychotic** primarily used for **treatment-resistant schizophrenia**. - It has significant side effects, including **agranulocytosis**, and is not indicated for eating disorders. *Reserpine* - An **antihypertensive** and **antipsychotic** drug that depletes catecholamines and serotonin from central neurons. - Due to its severe side effects, including **depression** and **parkinsonism**, it is rarely used today and not for eating disorders. *Pimozide* - A **first-generation antipsychotic** specifically approved for treating **Tourette's syndrome** but sometimes used off-label for severe tics. - It is not indicated for the treatment of bulimia nervosa and may carry significant **cardiac side effects**.

Question 5: A young lady presents with a history of repeated episodes of overeating followed by purging using laxatives. She is probably suffering from -

A. Binge eating disorder
B. Schizophrenia
C. Anorexia nervosa
D. Bulimia nervosa (Correct Answer)

Explanation: ***Bulimia nervosa*** - This condition is characterized by recurrent episodes of **binge eating** followed by inappropriate compensatory behaviors like **purging (e.g., laxative use)**, self-induced vomiting, excessive exercise, or fasting. - The patient's presentation of repeated overeating followed by purging with laxatives directly aligns with the diagnostic criteria for **bulimia nervosa**. *Binge eating disorder* - While it involves recurrent episodes of **binge eating**, it **does not include** the regular use of inappropriate compensatory behaviors such as purging. - Individuals with binge eating disorder typically experience significant distress about their binging but do not attempt to undo the caloric intake. *Schizophrenia* - This is a severe mental disorder characterized by **distortions in thinking, perception, emotions, language, sense of self, and behavior**, such as hallucinations and delusions. - It is a **psychotic disorder** and does not involve specific eating patterns or purging behaviors. *Anorexia nervosa* - This eating disorder is characterized by a persistent restriction of energy intake leading to a **significantly low body weight**, an intense **fear of gaining weight**, and a distorted body image. - Although some individuals with anorexia nervosa may engage in binge-purging type behavior, the primary defining feature is **significantly low body weight**, which is not mentioned in the patient's presentation.

Question 6: A young girl hospitalised with anorexia nervosa is on treatment. Even after taking adequate food according to the recommended diet plan for last 1 week, there is no gain in weight. What is the next step in management:

A. Increase the caloric intake from 1500 kcal to 2000 kcal per day
B. Increase fluid intake
C. Increase the dose of anxiolytics
D. Observe patient for 2 hours after meal (Correct Answer)

Explanation: ***Observe patient for 2 hours after meal*** - Patients with **anorexia nervosa** often engage in compensatory behaviors like **purging** or extensive exercise, which would counteract the effects of increased caloric intake and lead to a lack of weight gain despite consuming an "adequate" diet. - Observing the patient post-meal helps identify these behaviors and ensures that the ingested calories are actually being retained and utilized for weight restoration. *Increase the caloric intake from 1500 kcal to 2000 kcal per day* - Increasing caloric intake is a valid long-term strategy but is not the immediate next step when there's **no weight gain despite adequate intake**; the primary concern is identifying *why* the initial intake isn't leading to weight gain. - Doing so without addressing potential compensatory behaviors might only increase patient distress or lead to more intense purging/exercise. *Increase fluid intake* - While adequate **hydration** is important, it does not directly address the issue of **lack of weight gain** in anorexia nervosa, which is fundamentally a caloric deficit problem. - Increased fluid intake would not provide the necessary calories for weight restoration. *Increase the dose of anxiolytics* - Anxiolytics may help manage **anxiety** related to eating, but they do not directly promote **weight gain** or prevent compensatory behaviors. - This step does not address the core issue of why the recommended diet is not leading to weight gain.

Question 7: Management of a violent patient in psychiatry includes all except:

A. CBT (Correct Answer)
B. Haloperidol
C. ECT
D. BZD

Explanation: ***CBT*** - **Cognitive Behavioral Therapy (CBT)** is a long-term psychological intervention aimed at changing maladaptive thought patterns and behaviors. It is **not suitable for immediate management** of an acutely violent patient. - While CBT can be beneficial for aggression management in a stable patient, it requires patient cooperation, cognitive engagement, and time, which are not available during a **violent psychiatric emergency**. *Haloperidol* - **Haloperidol** is a potent typical antipsychotic frequently used in acute settings for rapid tranquilization of violent or severely agitated patients. - It is effective in reducing **psychosis-related agitation** and can be administered **intramuscularly** for quick onset of action. - Often used in combination with benzodiazepines for optimal control of acute violence. *ECT* - **Electroconvulsive Therapy (ECT)** may be considered in **severe, treatment-resistant cases** of violence associated with conditions like uncontrolled mania, catatonic excitement, or psychotic depression when pharmacological interventions have failed. - While not used for immediate acute management due to logistical requirements (consent, anesthesia, specialized setup), it can be an effective option for severe psychiatric conditions with persistent violence. - It works by inducing a brief controlled seizure, which can rapidly alleviate severe symptoms. *BZD* - **Benzodiazepines (BZDs)** like lorazepam or diazepam are **first-line agents** in the acute management of violent or agitated patients due to their rapid anxiolytic, sedative, and muscle relaxant properties. - They are particularly useful for **calming acute agitation** and are often combined with antipsychotics for rapid tranquilization. - Can be administered intramuscularly or intravenously for quick action in psychiatric emergencies.

Question 8: Which of the following is FALSE regarding Anorexia Nervosa:

A. Decreased appetite (Correct Answer)
B. Body image distortion
C. Vigor exceeding physical ill being
D. Weight loss

Explanation: ***Decreased appetite*** - Patients with anorexia nervosa typically experience **increased hunger** and **preoccupation with food**, despite efforts to restrict intake, rather than a decreased appetite. - The sensation of hunger often intensifies due to severe caloric restriction, making the statement "decreased appetite" false. *Body image distortion* - This is a core diagnostic criterion of anorexia nervosa, where individuals perceive themselves as **overweight** even when they are severely underweight. - The distorted body image drives their relentless pursuit of thinness and fear of weight gain. *Vigor exceeding physical ill being* - Patients with anorexia nervosa often display surprising **energy and hyperactivity** despite severe physical debilitation and malnutrition. - This "vigor" can be a mechanism to burn calories, suppress hunger, or avoid rest, exceeding what would be expected given their poor health status. *Weight loss* - **Significant weight loss** or failure to gain weight during growth is a defining characteristic of anorexia nervosa. - This weight loss is intentionally achieved through severe dietary restriction, excessive exercise, or purging behaviors.

Question 9: Laser uvulopalatoplasty is indicated for which of the following conditions?

A. Obstructive sleep apnea (Correct Answer)
B. Pharyngotonsillitis
C. Cleft palate
D. Stammering

Explanation: ***Obstructive sleep apnea*** - **Laser uvulopalatoplasty (LUP)** is a surgical procedure that reshapes the **uvula** and **soft palate** to enlarge the airway in patients with **obstructive sleep apnea (OSA)**. - OSA is characterized by repetitive episodes of upper airway obstruction during sleep, leading to snoring, daytime sleepiness, and other health issues. *Pharyngotonsillitis* - This condition involves inflammation of the **pharynx** and **tonsils**, usually caused by bacterial or viral infections. - Treatment typically involves antibiotics for bacterial infections or symptomatic relief for viral infections, not surgical reshaping of the palate. *Cleft palate* - **Cleft palate** is a congenital birth defect where the roof of the mouth does not fully close during fetal development. - The primary treatment involves **surgical repair** to close the opening, which is a different procedure from LUP and focuses on reconstructing normal anatomy. *Stammering* - **Stammering** is a **speech disorder** characterized by disruptions in fluency, such as repetitions, prolongations, or blocks in speech. - It is managed through **speech therapy** and behavioral interventions, and is unrelated to airway obstruction or surgical procedures on the palate.

Question 10: Which of the following is not a known cause of neuroregression in children?

A. Vitamin B12 deficiency
B. Ataxia telangiectasia
C. ADHD (Correct Answer)
D. Wilson's disease

Explanation: ***ADHD*** - **Attention-deficit/hyperactivity disorder (ADHD)** is a neurodevelopmental disorder characterized by persistent patterns of inattention, hyperactivity, and impulsivity. It is **not** a cause of neuroregression. - While ADHD can impact cognitive and behavioral functioning, it does not involve a loss of previously acquired developmental milestones or skills. *Wilson's disease* - **Wilson's disease** is an inherited disorder that causes **copper accumulation** in organs, particularly the liver and brain. - Neurological symptoms, including **neuroregression**, can occur due to copper toxicity in the central nervous system. *Vitamin B12 deficiency* - **Vitamin B12 deficiency** can lead to neurological complications such as **subacute combined degeneration** of the spinal cord and peripheral neuropathy. - In children, severe or prolonged deficiency can impair brain development and lead to **developmental regression**. *Ataxia telangiectasia* - **Ataxia telangiectasia** is a rare, neurodegenerative, inherited disease that affects multiple body systems. - It is characterized by progressive **cerebellar ataxia**, leading to **neuroregression** and intellectual disability over time.
