Sleep Disorders

Normal Sleep & Its Importance - Sleepy Foundations

• Sleep Cycles: Alternating NREM (Non-Rapid Eye Movement) & REM (Rapid Eye Movement) sleep; cycle duration ~90-120 min.
• NREM Sleep (75-80% total sleep):
  • N1: Light sleep, easy arousal.
  • N2: Deeper, K-complexes & sleep spindles on EEG.
  • N3 (SWS - Slow Wave Sleep): Deepest, restorative; growth hormone (GH) secretion peaks.
• REM Sleep (20-25% total sleep):
  • Active brain (dreaming), muscle atonia.
  • Crucial for learning, memory consolidation, emotional regulation.
• Importance: Physical restoration, cognitive function (memory, attention), mood regulation, immune system support.
• Age Variation:
  • Infants: ↑REM sleep proportion, shorter sleep cycles.
  • Elderly: ↓SWS, ↑night awakenings, ↓sleep efficiency.

⭐ Newborns spend approximately 50% of their sleep time in REM sleep, which gradually decreases with age.

Dyssomnias - Can't Catch Zzz's

• Difficulty initiating/maintaining sleep (DIMS) or excessive sleepiness (EDS).
• Insomnia:
  • Behavioral Insomnia of Childhood (BIC): Commonest.
    • Limit-setting type: Bedtime resistance.
    • Sleep-onset association type: Needs specific conditions.
  • Management: Sleep hygiene, behavioral therapy.
• Obstructive Sleep Apnea (OSA):
  • Symptoms: Snoring, mouth breathing, daytime sleepiness.
  • Diagnosis: Polysomnography (PSG).
  • Management: Adenotonsillectomy, CPAP.

  ⭐ Adenotonsillar hypertrophy is the most common cause of Obstructive Sleep Apnea (OSA) in children.

• Narcolepsy:
  • EDS, cataplexy, sleep paralysis, hallucinations.
  • ↓Hypocretin-1. HLA-DQB1*0602.
  • Management: Modafinil, stimulants.
• Restless Legs Syndrome (RLS):
  • Urge to move legs, worse at night, relieved by movement.
  • Iron deficiency link.
  • Management: Iron, dopamine agonists.

Parasomnias - Nighttime Adventures

Abnormal behaviors/experiences during sleep or sleep-wake transitions.

• NREM Arousal Disorders (Stage N3 Sleep):
  • Sleepwalking (Somnambulism): Complex motor acts; amnesia.
  • Sleep Terrors (Pavor Nocturnus): Sudden arousal, intense fear, autonomic signs (tachycardia, tachypnea); inconsolable; amnesia.
  • Confusional Arousals: Disorientation on waking.
  • Common in children; often outgrown.
  • Management: Safety, reassurance; rarely benzodiazepines.
• REM Sleep Parasomnias:
  • REM Sleep Behavior Disorder (RBD): Dream enactment (loss of REM atonia); risk of injury. Assoc. with neurodegenerative diseases (Parkinson's). Rx: Clonazepam.
  • Nightmare Disorder: Frightening dreams; detailed recall; late REM. Rx: Reassurance.

⭐ NREM parasomnias like sleep terrors and sleepwalking typically occur in the first third of the night, during slow-wave sleep, and are associated with amnesia for the event.

Evaluation & Management - Sweet Dreams Plan

• Initial Evaluation:
  • Comprehensive sleep history: 📌 BEARS mnemonic.
  • Detailed sleep diary: 1-2 weeks duration.
  • Physical exam: identify contributors (e.g., adenotonsillar hypertrophy, obesity).
  • Screen for relevant comorbidities.
• Management Approach:
  • Sleep Hygiene Education (First-line therapy):
    • Consistent bedtime & wake-up schedule.
    • Calm, predictable bedtime routine.
    • Conducive environment: dark, quiet, cool, safe.
    • No electronic screens 1-2 hours before bed.
    • Avoid caffeine/heavy meals close to bedtime.
  • Behavioral Therapies: Extinction, positive reinforcement, stimulus control.
  • Pharmacotherapy (Adjunctive/Resistant cases): Melatonin; always specialist consultation.

⭐ The BEARS mnemonic (Bedtime problems, Excessive daytime sleepiness, Awakenings during the night, Regularity and duration of sleep, Snoring) is a useful screening tool for pediatric sleep problems.

High‑Yield Points - ⚡ Biggest Takeaways

• Parasomnias (night terrors, somnambulism) are NREM (N3) sleep events, typically with amnesia.
• Nightmares are REM sleep phenomena, characterized by vivid recall.
• Pediatric OSA is commonly linked to adenotonsillar hypertrophy; polysomnography is diagnostic.
• Behavioral Insomnia of Childhood (BIC) includes sleep-onset association and limit-setting types.
• Restless Legs Syndrome (RLS) in children may indicate iron deficiency (check ferritin).
• Narcolepsy features Excessive Daytime Sleepiness (EDS), cataplexy; associated with low CSF hypocretin-1.
• Delayed Sleep-Wake Phase Disorder: persistent late sleep onset and wake times, common in adolescents.
