Sleep Hygiene and Other Non-pharmacological Approaches Indian Medical PG Practice Questions and MCQs
Question 1: All are included in sleep hygiene except which of the following?
- A. Healthy diet
- B. Exercising vigorously before sleep (Correct Answer)
- C. Sleeping on time
- D. Sleeping in dark room
Explanation: ***Exercising vigorously before sleep*** - **Vigorous exercise** elevates body temperature, heart rate, and stimulates the central nervous system, making it harder to fall asleep and reducing sleep quality. - This practice directly contradicts the principles of sleep hygiene, which promote relaxing activities before bedtime. - While regular exercise is beneficial for sleep, it should be completed at least **3-4 hours before bedtime**. *Healthy diet* - A **balanced diet** and mindful eating patterns are important components of sleep hygiene. - Sleep hygiene recommendations include avoiding **heavy meals, caffeine, and alcohol** close to bedtime, as these can disrupt sleep quality. - Proper nutrition supports the physiological processes necessary for restorative sleep. *Sleeping on time* - Maintaining a **consistent sleep schedule**, even on weekends, helps regulate the body's natural **circadian rhythm**. - This consistency reinforces the sleep-wake cycle, making it easier to fall asleep and wake up naturally. - Going to bed and waking up at the same time daily is a cornerstone of good sleep hygiene. *Sleeping in a dark room* - A **dark environment** signals to the brain that it's time to release **melatonin**, the hormone that promotes sleep. - Exposure to light, especially blue light from screens, can suppress melatonin production and interfere with sleep onset. - Creating an optimal sleep environment (dark, quiet, cool) is a fundamental sleep hygiene principle.
Question 2: Which anxiolytic acts through 5-HT1A receptor partial agonism without exhibiting significant anticonvulsant or muscle relaxant properties?
- A. Diazepam
- B. Zolpidem
- C. Phenobarbitone
- D. Buspirone (Correct Answer)
Explanation: ***Buspirone*** - **Buspirone** is a unique anxiolytic that primarily acts as a **partial agonist at 5-HT1A receptors**. - Unlike benzodiazepines, it lacks significant **anticonvulsant**, **muscle relaxant**, or **sedative-hypnotic properties** and does not lead to physical dependence or withdrawal. *Diazepam* - **Diazepam** is a **benzodiazepine** that acts by enhancing the effect of **GABA** at GABA-A receptors, leading to significant anxiolytic, sedative, muscle relaxant, and anticonvulsant effects. - It does not primarily act via **5-HT1A receptor partial agonism**. *Zolpidem* - **Zolpidem** is a **non-benzodiazepine hypnotic** that selectively binds to the **GABA-A receptor** subunit, primarily mediating sedative effects. - While it's used for insomnia, it doesn't primarily act as a **5-HT1A partial agonist** and is not typically used for its anxiolytic properties in the same way as buspirone. *Phenobarbitone* - **Phenobarbitone** is a **barbiturate** that acts by prolonging the opening of **chloride channels** associated with GABA-A receptors, leading to strong sedative, hypnotic, and anticonvulsant effects. - Its mechanism of action is distinct from **5-HT1A receptor partial agonism**, and it carries a high risk of dependence and overdose.
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: Which of the following treatments cannot be used for management of Obsessive Compulsive Disorder (OCD)?
- A. Fluoxetine
- B. Carbamazepine (Correct Answer)
- C. Cognitive Behaviour Therapy
- D. Clomipramine
Explanation: ***Carbamazepine*** - **Carbamazepine** is an **anticonvulsant** and **mood stabilizer** primarily used for epilepsy and bipolar disorder. - It does not have established efficacy for the treatment of **Obsessive-Compulsive Disorder (OCD)**. *Fluoxetine* - **Fluoxetine** is a **Selective Serotonin Reuptake Inhibitor (SSRI)** and is a **first-line pharmacotherapy** for OCD. - SSRIs, including fluoxetine, are effective in reducing the severity of **obsessions and compulsions**. *Cognitive Behaviour Therapy* - **Cognitive Behavioural Therapy (CBT)**, specifically **Exposure and Response Prevention (ERP)**, is the **gold standard psychotherapy** for OCD. - It involves gradually exposing patients to feared situations or thoughts while preventing their ritualistic responses. *Clomipramine* - **Clomipramine** is a **tricyclic antidepressant (TCA)** that has potent inhibitory effects on **serotonin reuptake**. - It is one of the **most effective medications** for OCD, often used when SSRIs are insufficient.
Question 5: A child presents with complaints of bed wetting. What is the first line of treatment?
- A. Bed alarm technique (Correct Answer)
- B. Motivational therapy
- C. Oxybutynin
- D. Desmopressin
Explanation: ***Bed alarm technique*** - The **bed alarm technique** is considered the most effective first-line treatment for **nocturnal enuresis** in children. - It works through **classical conditioning**, training the child to wake up in response to bladder fullness. *Motivational therapy* - **Motivational therapy** can be a useful adjunct to other treatments, but it is not typically the sole **first-line therapy** due to varying effectiveness. - It focuses on building the child's confidence and encouraging dryness but does not directly address the physiological aspects of bedwetting. *Oxybutynin* - **Oxybutynin** is an anticholinergic medication that can reduce bladder contractions and increase bladder capacity. - It is usually reserved for cases where **bedwetting alarms** and **desmopressin** have been ineffective, or when there is an identifiable **overactive bladder component**. *Desmopressin* - **Desmopressin** is an antidiuretic hormone analogue that reduces urine production during the night. - While effective, it is often considered a **second-line treatment** after behavioral interventions like the bed alarm, or when rapid but temporary improvement is desired.
Question 6: All are used in the treatment of nocturnal enuresis except?
- A. Voiding of urine before sleeping (Correct Answer)
- B. Imipramine
- C. Alarm setup
- D. Maintenance of calendar of day night wetting
Explanation: ***Voiding of urine before sleeping*** - **Voiding before sleep** is a **general hygiene measure and preventive advice** rather than a specific therapeutic intervention for nocturnal enuresis. - While it may reduce bladder volume at bedtime, it does **not address the underlying pathophysiology** of nocturnal enuresis (arousal deficit, nocturnal polyuria, or detrusor overactivity). - It is **routine advice** given to all children, not a targeted treatment modality for curing enuresis. *Imipramine* - **Imipramine**, a tricyclic antidepressant, is an established **pharmacological treatment** for nocturnal enuresis. - Its mechanisms include: **anticholinergic effects** (increasing bladder capacity and functional bladder capacity), **alpha-adrenergic effects** (increasing bladder outlet resistance), and **antidiuretic effects**. - Typical dosing: **25-50 mg at bedtime**, with success rates of 40-60%. *Alarm setup* - **Bed-wetting alarms** are the **first-line behavioral therapy** with the highest long-term cure rates (60-70% success). - Works through **classical conditioning**: the alarm triggers when moisture is detected, training the child to either wake to void or develop nocturnal bladder control. - Requires **8-12 weeks** of consistent use and has the lowest relapse rates among treatments. *Maintenance of calendar of day night wetting* - **Voiding diary/calendar** is an essential **behavioral intervention** for monitoring and managing nocturnal enuresis. - Helps identify patterns, track treatment progress, and provides **positive reinforcement** through visual feedback. - Part of comprehensive behavioral management alongside fluid restriction and scheduled voiding during daytime.
Question 7: Best treatment for nocturnal enuresis is
- A. Positive reinforcement
- B. Punishment
- C. Bed alarm (Correct Answer)
- D. Desmopressin
Explanation: ***Bed alarm*** - **Bed alarms** are considered the most effective long-term treatment for nocturnal enuresis by conditioning the child to wake up to a full bladder. - This method has a high success rate and a lower relapse rate compared to pharmacological treatments. *Positive reinforcement* - While helpful for building confidence and encouraging adherence to treatment, **positive reinforcement** alone is generally not sufficient to cure nocturnal enuresis. - It works best as an adjunct to other established treatments, like bed alarms, to motivate the child. *Punishment* - **Punishment** is not an effective or appropriate treatment for nocturnal enuresis and can be psychologically harmful to the child. - Enuresis is an involuntary condition, and punishment can lead to increased stress, anxiety, and shame, potentially worsening the problem. *Desmopressin* - **Desmopressin** (DDAVP) is a synthetic analog of antidiuretic hormone and can reduce urine production at night, offering a short-term solution. - It is effective in reducing the frequency of wet nights but has a higher relapse rate once discontinued, and it does not cure the underlying problem like a bed alarm does.
Question 8: Bruxism most commonly occurs during which phase of sleep?
- A. REM sleep
- B. NREM Stage I
- C. NREM Stage II (Correct Answer)
- D. NREM Stage III
Explanation: **Explanation:** **Sleep Bruxism** is a sleep-related movement disorder characterized by the involuntary grinding or clenching of teeth. **Why NREM Stage II is correct:** While bruxism can occur in any stage of sleep, it is most frequently observed during **NREM Stage II (Light Sleep)**. Statistically, about 80% of bruxism episodes occur during NREM sleep, with the vast majority clustered in Stage II. These episodes are often associated with "micro-arousals"—brief shifts in sleep depth where the sympathetic nervous system activity increases, leading to rhythmic masticatory muscle activity (RMMA). **Analysis of Incorrect Options:** * **REM Sleep (A):** Although bruxism can occur during REM, it is less common. REM-related bruxism is often associated with more severe clinical symptoms and may be linked to obstructive sleep apnea. * **NREM Stage I (B):** This is a transitional phase of very light sleep. While grinding can occur here, the frequency is significantly lower than in Stage II. * **NREM Stage III (D):** Also known as Slow Wave Sleep (SWS) or deep sleep. Parasomnias like sleepwalking (somnambulism) and night terrors typically occur here, but bruxism is less frequent in this stage compared to Stage II. **High-Yield Clinical Pearls for NEET-PG:** * **Treatment of Choice:** The first-line management is usually **stress reduction** and **dental guards (occlusal splints)** to prevent tooth wear. * **Pharmacotherapy:** If severe, **Benzodiazepines** (like Clonazepam) or muscle relaxants may be used short-term. * **Association:** Bruxism is frequently associated with stress, anxiety, and other sleep disorders like Obstructive Sleep Apnea (OSA). * **Key Distinction:** Do not confuse bruxism (Stage II) with **Sleep Terrors/Somnambulism**, which are classic **Stage III (N3)** phenomena.
Question 9: What is a feature of narcolepsy?
- A. Insomnia
- B. Hypersomnia during the day (Correct Answer)
- C. Bruxism
- D. Somnambulism
Explanation: **Explanation:** **Narcolepsy** is a chronic neurological disorder characterized by the brain's inability to regulate sleep-wake cycles normally. The hallmark feature is **excessive daytime sleepiness (EDS)** or hypersomnia, where patients experience an irrepressible need to sleep or "sleep attacks" regardless of the amount of sleep they get at night. This occurs due to the loss of orexin (hypocretin)-producing neurons in the hypothalamus, which are responsible for maintaining wakefulness. **Analysis of Options:** * **Option B (Correct):** Hypersomnia is the primary symptom. Patients often enter REM sleep directly from wakefulness (SOREMPs), leading to refreshing but short naps. * **Option A:** Insomnia refers to difficulty initiating or maintaining sleep. While narcoleptics may have fragmented nocturnal sleep, the defining diagnostic feature is daytime hypersomnia. * **Option C:** Bruxism (teeth grinding) is a sleep-related movement disorder, not a primary feature of narcolepsy. * **Option D:** Somnambulism (sleepwalking) is a NREM parasomnia. Narcolepsy is primarily associated with REM sleep dysregulation. **High-Yield Clinical Pearls for NEET-PG:** * **The Classic Tetrad:** 1. Excessive Daytime Sleepiness, 2. **Cataplexy** (sudden loss of muscle tone triggered by emotions—most specific sign), 3. Sleep Paralysis, and 4. Hypnagogic/Hypnopompic hallucinations. * **Diagnosis:** Gold standard is the **Multiple Sleep Latency Test (MSLT)** showing a mean sleep latency <8 minutes and ≥2 SOREMPs. * **Treatment:** Modafinil (first-line for EDS); Sodium Oxybate (effective for both EDS and cataplexy).
Question 10: Benzodiazepines are used in the treatment of somnambulism because they?
- A. Increase the duration of NREM stages III and IV
- B. Increase the duration of REM sleep
- C. Decrease the duration of NREM stages III and IV (Correct Answer)
- D. Decrease the duration of REM sleep
Explanation: **Explanation:** **Somnambulism (Sleepwalking)** is a parasomnia that occurs during **NREM Stage N3 (Stage III and IV)**, also known as slow-wave sleep (SWS) or deep sleep. This is the stage characterized by high-arousal thresholds and rhythmic delta waves. **Why the correct answer is right:** Benzodiazepines (such as Diazepam or Alprazolam) are effective in treating somnambulism because they **suppress and decrease the duration of NREM Stage III and IV sleep**. By reducing the time a patient spends in these deep sleep stages, the physiological window in which sleepwalking occurs is minimized, thereby reducing the frequency of episodes. **Why the incorrect options are wrong:** * **Option A:** Increasing NREM Stage III and IV would theoretically increase the risk and frequency of sleepwalking episodes, as the disorder originates in these stages. * **Option B & D:** While Benzodiazepines are known to **decrease REM sleep** (Option D), this is not the primary reason they are used for somnambulism. Somnambulism is an NREM disorder; REM-related disorders include Nightmares and REM Sleep Behavior Disorder (RBD). Therefore, the effect on NREM is the clinically relevant mechanism here. **High-Yield Clinical Pearls for NEET-PG:** * **Timing:** Sleepwalking typically occurs during the **first third** of the night (when NREM sleep is most abundant). * **Amnesia:** Patients usually have complete amnesia regarding the episode the following morning. * **Management:** The first line of management is usually **safety precautions** and sleep hygiene. Pharmacotherapy (Benzodiazepines) is reserved for refractory or dangerous cases. * **Differential:** Unlike sleepwalking, **Nightmares** occur during REM sleep, usually in the later part of the night, and the patient has vivid recall.
