Study Notes
Overview of Sleep Disorders
- Growing awareness of sleep problems' impact on mental and physical health has led to increased specialization in sleep medicine.
- Sleep disorders encompass both dyssomnias (insomnia, hypersomnia) and parasomnias (behaviors associated with sleep).
- Sleep issues can indicate primary sleep disorders, be a symptom of psychiatric conditions, or contribute to psychiatric disorders.
Persistent Sleep Difficulties
- Persistent sleep issues are linked to various negative physical health outcomes.
Classification of Sleep Disorders
- DSM-5 identifies 10 sleep-wake disorders including insomnia disorder, hypersomnolence disorder, and narcolepsy.
- ICD-10 categorizes sleep disorders based on aetiology, including non-organic and organic sleep disorders.
Assessment of Sleep Disturbance
- Key screening questions evaluate sleep quality, daytime sleepiness, and nighttime disturbances.
- A comprehensive sleep history and sleep diary help document sleep patterns and related factors.
- Investigations may include actigraphy, polysomnography, and cerebrospinal fluid analysis.
Treatments for Insomnia
- Cognitive and Behavioral Interventions focus on sleep hygiene, sleep restriction, and relaxation techniques.
- Pharmacological Treatments range from short-acting benzodiazepines to melatonin agonists and low-dose sedative antidepressants.
Principles of Sleep Education (Sleep Hygiene)
- Optimal sleep environment: familiar, dark, and quiet.
- Recommended practices include regular bedtime, limited screentime before sleep, and consistent routines.
- Activities to avoid: late exercise, caffeine, excessive alcohol, and large meals before bed.
Insomnia
- Defined as unsatisfactory sleep quality or quantity with difficulty falling asleep, staying asleep, or waking too early.
- Often secondary to other conditions like depression, anxiety, or physical ailments.
- Diagnosis requires persistent insomnia occurring at least three nights per week for a month (ICD-10) or three months (DSM-5).
Narcolepsy
- A neurological disorder characterized by excessive daytime sleepiness, cataplexy, and hypnagogic hallucinations.
- Type 1 narcolepsy involves reduced orexin-A levels and is linked to specific genetic markers (HLA-DQB1*06:02).
- Treatment includes sleep management, stimulant medications, and occasionally antidepressants.
Breathing-Related Sleep Disorder
- Defined by daytime drowsiness with recurrent apneas, often linked to upper airway obstruction.
- About 4% of males are affected, with management focused on addressing the underlying causes and promoting weight loss.
Kleine-Levin Syndrome
- Rare disorder marked by episodes of excessive sleep, hyperphagia, and hypersexuality.
- Affects primarily adolescent boys, with unknown causes and variable treatment approaches, including stimulants and mood stabilizers.
Circadian Rhythm Sleep Disorder
- Encompasses conditions like jet lag and shift-work disorder, leading to fatigue and sleep disturbances due to irregular sleep patterns.
Hypersomnia and Excessive Daytime Sleepiness
- Commonly underdiagnosed, with prevalence estimates of 3-5%.
- Can result from insufficient sleep, medical disorders, or sedative medication use.
Parasomnias
- Abnormal behaviors accompanying sleep, prevalent in children and increasing with age-related disorders.
- Nightmares: Typically peak during childhood; related to anxiety and stressful experiences.
- Night Terrors: More common in childhood; involve episodes of terror within hours of sleep onset.
- Sleepwalking: Typically occurs in children; characterized by repetitive movements or walking while seemingly asleep.
- REM Sleep Behavior Disorder: Agitation during REM sleep; may precede neurodegenerative diseases.
- Restless Legs Syndrome: Painful condition causing disruptive sleep; prevalent among women and the elderly.
- Sleep Paralysis: Characterized by temporary inability to move during sleep transition, often accompanying fear.
Accidents and Behavioral Effects
- Sleep disorders can increase the risk of accidents and significantly impact social and emotional well-being, especially in adolescents.
