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.
