Study Notes

Overview of Sleep and Sleep Disorders

Sleep disorders involve lack of awareness of surroundings, yet ability to be easily aroused.
Sleep insufficiency hinders optimal health, alertness, and functioning.
Sleep deprivation entails insufficient sleep for individual needs.
Sleep fragmentation refers to frequent awakenings disrupting normal sleep.
Poor sleep quality, known as sleep disturbances, is influenced by health and environmental factors.
Common sleep disorders include insomnia, obstructive sleep apnea (OSA), periodic limb movements, circadian sleep disorders, narcolepsy, and parasomnias.

Brain & Sleep Regulation

The cerebral cortex, hypothalamus, thalamus, and brainstem coordinate the sleep-wake cycle.
Ascending reticular activating system (ARAS) and neurotransmitters affect wakefulness and attention.
Sleep-promoting neurons in the hypothalamus inhibit ARAS to induce sleep.
Melatonin, produced by the pineal gland, is integral to the light-dark cycle regulation.
Circadian rhythms, governed by the suprachiasmatic nucleus (SCN), dictate the sleep-wake cycle pattern.

Sleep States & Effects of Disorders

Two main sleep states: Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM) sleep.
Sleep deprivation and disorders can lead to hospitalization, disrupted sleep stages, delirium, and delayed recovery.
Insomnia is the most prevalent sleep disorder, particularly affecting women and individuals with lower socioeconomic status.

Insomnia Characteristics & Management

Manifestations include difficulty initiating sleep, maintenance issues, waking early, and resistance to going to bed.
Multi-faceted approach: early intervention to prevent progression from short-term to chronic insomnia is essential.
Cognitive-behavioral therapy for insomnia (CBT-I) paired with education on sleep hygiene is effective.
Drug therapy is tailored to individual patterns, recommended primarily for short-term use.
Benzodiazepine-receptor agonists are advised intermittently; patients must be aware of side effects like sleepwalking.
Orexin-receptor antagonists and melatonin receptor agonists are alternatives for specific insomnia patterns.

Complementary Therapies & Assessment

Melatonin may aid circadian rhythm disorders.
Herbal remedies require further research for efficacy.
Assessment involves identifying personal habits, diet, and environmental factors affecting sleep.
Utilizing a sleep diary can help monitor patterns.

Obstructive Sleep Apnea (OSA)

OSA affects around 25% of US adults; key risk factors include obesity and advanced age.
Symptoms include insomnia, excessive daytime sleepiness, snoring, morning headaches, and mood changes.
Diagnosis involves medical history and questionnaires (Berlin, STOP-BANG) along with diagnostic studies like polysomnography (PSG).
Treatment options include behavioral changes, CPAP and BiPAP devices, and surgical interventions.

Periodic Limb Movement Disorder & Other Disorders

Periodic limb movement disorder (PLMD) is characterized by involuntary limb movements disrupting sleep.
Jet lag and shift work disorders lead to sleep-wake cycle disruptions and excessive daytime sleepiness.
Increased incidence of sleep disorders in older adults due to changes in sleep architecture.
Chronic conditions prevalent in older adults can exacerbate sleep issues.

Nursing Care Considerations

Emphasize the importance of sleep assessments and cautious medication use.
Avoid long-acting benzodiazepines in older patients due to increased fall risk.
Address social factors impacted by shift work, including job satisfaction and social engagement, to mitigate sleep disorders.

Sleep Disorders Overview

Sleep Disorders: Individuals lack conscious awareness but can be easily aroused.
Sleep Insufficiency: Insufficient sleep does not support optimal alertness or health.
Sleep Deprivation: Occurs when sleep is too little to meet an individual's needs.
Sleep Fragmentation: Characterized by frequent awakenings during sleep.
Sleep Disturbances: Poor sleep quality due to health-related or environmental factors.
Types of Sleep Disorders include insomnia, obstructive sleep apnea (OSA), periodic limb movements, circadian sleep disorders, narcolepsy, and parasomnias.

Brain Function in Sleep

Brain structures such as the cerebral cortex, hypothalamus, thalamus, and brainstem regulate sleep-wake cycles.
Wake Behavior: The ascending reticular activating system (ARAS) and neurotransmitters enhance alertness.
Sleep Behavior: Sleep-promoting neurons inhibit the ARAS, facilitating sleep.
Melatonin: A hormone from the pineal gland influenced by light-dark cycles, plays a role in sleep regulation.

Circadian Rhythms

Suprachiasmatic nucleus (SCN) in the hypothalamus regulates 24-hour biological rhythms.
Circadian Rhythms are assessed using polysomnography (PSG), EEG, electromyogram (EMG), and electrooculogram (EOG).
Sleep has two primary states: Rapid eye movement (REM) and Non-rapid eye movement (NREM).

Impact of Sleep Disorders

Sleep deprivation can lead to hospitalization, disrupted sleep stages, circadian rhythm disorders, and other health issues.
Insomnia is the most prevalent sleep disorder, often affecting women and individuals in lower socioeconomic groups.
Common symptoms of insomnia include difficulty falling asleep, maintaining sleep, waking too early, and reluctance to adhere to sleep schedules.

Insomnia Management

Interprofessional care focuses on preventing short-term insomnia from becoming chronic.
Behavioral strategies and cognitive-behavioral therapy for insomnia (CBT-I) are effective treatments.
Regular exercise and avoiding daytime napping are recommended for better sleep quality.

Drug Therapy for Insomnia

Personalized drug therapy is essential, particularly for chronic insomnia.
Medications may lead to daytime impairment and rebound insomnia when discontinued.
Benzodiazepine-receptor agonists are recommended for sleep onset and maintenance but should be used cautiously.
Orexin-receptor antagonists block orexin effects for sleep onset/maintenance.
Melatonin receptor agonists can assist with sleep onset but may not always be effective.

Assessment and Treatment

Evaluation should consider personal habits, environmental factors, diet, caffeine intake, and sleep aids.
Sleep diaries may help identify patterns contributing to poor sleep.
Implementation of strategies depends on the severity of sleep issues, with education on sleep hygiene being vital.

Obstructive Sleep Apnea (OSA)

OSA occurs in approximately 25% of US adults; risk factors include obesity, older age, male gender, and postmenopausal status.
Symptoms of OSA encompass insomnia, excessive daytime sleepiness, arousals, apneic episodes, snoring, and morning headaches.
Assessment tools include sleep and medical history, questionnaires, and polysomnography.

OSA Treatment

Behavioral treatments involve weight loss, positional therapy, and avoiding sedatives.
Medical devices like CPAP and BiPAP are used for severe cases.
Surgical options may include Uvulopalatopharyngoplasty (UPPP), Genioglossal advancement, and newer investigational neurostimulators.

Other Sleep Disorders

Periodic Limb Movement Disorder (PLMD) involves reduced muscle activity; treatment may include dopaminergic agents like selegiline.
Jet Lag Disorder: Disruption of sleep-wake cycles post-travel.
Shift Work Sleep Disorder often leads to insomnia and excessive daytime sleepiness, impacting job satisfaction and social engagement.

Older adults experience shorter sleep duration and decreased efficiency, increasing risks of falls and chronic conditions.
Caution is advised when prescribing sleep medications in older patients, particularly avoiding long-acting benzodiazepines.
Chronic conditions such as depression and cardiovascular disease are prevalent in older adults, affecting sleep health.
