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.
