Study Notes
Sleep
- Sleep involves a lack of conscious awareness of surroundings but allows for easy arousal.
- It is a basic, dynamic, and necessary behavior crucial for mood, behavior, physical functioning, and survival.
- Insufficient sleep can lead to decreased alertness and health issues.
- Sleep disorders such as insomnia, obstructive sleep apnea (OSA), and narcolepsy represent unique abnormalities impacting sleep quality.
Sleep Disturbances and Disorders
- Sleep disturbances refer to conditions resulting in poor sleep quality, often due to health or environmental factors.
- Sleep disorders are specific abnormalities affecting sleep quality, often underestimated and associated with significant health, safety, and economic consequences.
Sleep–Wake Cycle
- The sleep-wake cycle is regulated by the brain, involving the cerebral cortex, hypothalamus, thalamus, and brainstem.
- Wakefulness is mediated by ARAS and neurotransmitters that activate the cerebral cortex.
- Sleep is promoted by hypothalamic neurons and the hormone melatonin, which is affected by light exposure.
Circadian Rhythms
- Circadian rhythms are 24-hour biological fluctuations regulated by the suprachiasmatic nucleus in the hypothalamus.
- Light serves as a strong cue, helping synchronize these rhythms which dictate the sleep-wake cycle.
Sleep Architecture
- Polysomnography (PSG) is used to record sleep patterns, which include muscle tone (EMG), eye movements (EOG), and brain activity (EEG).
- Two main sleep states: Rapid Eye Movement (REM) and Non-Rapid Eye Movement (NREM), with 4-6 cycles occurring nightly.
NREM Sleep
- NREM sleep constitutes 75-80% of total sleep time and is divided into three stages:
- N1: Transition to sleep; easily awakened.
- N2: Major sleep stage where heart rate and temperature drop.
- N3: Deep sleep stage characterized by delta brain waves.
REM Sleep
- REM sleep, accounting for 20-25% of sleep, follows NREM and is characterized by brain activity resembling wakefulness, postural muscle inhibition, and vivid dreaming.
Effects of Sleep Deprivation
- Sleep deprivation and disorders can lead to significant impairments including fatigue, affecting overall quality of life and recovery, especially in hospital settings.
Insomnia
- Insomnia is the most prevalent sleep disorder, affecting approximately one in three adults, characterized by difficulty falling or staying asleep, waking up early, or feeling unrefreshed.
- Chronic insomnia affects around 10% of Americans, more frequently seen in specific demographics such as women and individuals with lower socioeconomic status.
Insomnia Diagnosis and Management
- Insomnia is assessed through self-reported sleep diaries, comprehensive sleep history, and actigraphy.
- Management includes behavioral strategies, sleep hygiene education, cognitive-behavioral therapy (CBT-I), and, if necessary, drug therapy tailored to individual patterns of insomnia.
Sleep-Disordered Breathing (SDB)
- SDB entails abnormal respiratory patterns during sleep, including snoring and apnea, leading to sleep disruptions.
- Obstructive Sleep Apnea (OSA) is the most common form of SDB, affecting around 25% of adults in the U.S.
Obstructive Sleep Apnea (OSA)
- OSA involves upper airway obstruction during sleep, prominent during REM sleep when muscle tone is lowest, resulting in repeated apnea episodes.
- Key risk factors include obesity, age over 65, larger neck circumference, and gender (more common in males and postmenopausal women).
Diagnosis and Management of OSA
- Assessment involves a combination of sleep history, questionnaires (Berlin, STOP-BANG), and PSG for accurate diagnosis.
- Treatment options include behavioral changes, continuous positive airway pressure (CPAP) devices, surgical interventions to enhance airway patency, and potential use of oral appliances.
General Considerations
- Effective management of sleep disorders necessitates a thorough understanding of patient habits, environmental factors, and the careful use of medications.
- Collaboration with an interprofessional team is crucial for optimizing patient outcomes related to sleep health.
Sleep Overview
- Sleep involves lack of conscious awareness of surroundings, easily reversible state.
- Essential for mood, behavior, physical functioning, and overall survival.
- Types of sleep issues include insufficiency (insufficient sleep for optimal functioning), deprivation (too little sleep), and fragmentation (frequent awakenings).
Sleep Disturbances and Disorders
- Sleep disturbances refer to conditions that compromise sleep quality, often due to health or environmental factors.
- Sleep disorders are abnormalities specific to sleep patterns, including insomnia, obstructive sleep apnea (OSA), and narcolepsy.
- These disorders can lead to significant health, safety, and economic issues.
Sleep–Wake Cycle
- Controlled by brain regions: cerebral cortex, hypothalamus, thalamus, and brainstem.
- Wakefulness is influenced by neurotransmitters that activate the cerebral cortex; illnesses or medications may hinder this process.
- Sleep-promoting neurons in the hypothalamus help initiate sleep by inhibiting wakefulness mechanisms; melatonin contributes to this process.
Circadian Rhythms
- Governed by the suprachiasmatic nucleus (SCN) in the hypothalamus; this acts as the master clock for the 24-hour sleep-wake cycle.
- Light is a significant time cue and can influence sleep timing through light therapy.
Sleep Architecture
- Sleep is recorded using polysomnography (PSG), measuring brain activity (EEG), eye movements (EOG), and muscle tone (EMG).
- Two primary sleep states: Rapid eye movement (REM) and non-rapid eye movement (NREM) sleep.
- Each sleep cycle lasts 60-110 minutes, consisting of 4-6 NREM and REM cycles.
NREM and REM Sleep
- NREM sleep comprises 75-80% of total sleep, with three stages:
- N1: Light sleep, easy to awaken.
- N2: Most common stage, heart rate and temperature decrease.
- N3: Deep sleep characterized by delta waves indicating sleep intensity.
- REM sleep accounts for 20-25% of sleep, associated with vivid dreaming and brain activity resembling wakefulness.
Insomnia
- Most prevalent sleep disorder affecting approximately 1 in 3 adults.
- Can be categorized into short-term (less than 3 months) and chronic (3 months or longer, prevalent in 10% of Americans).
- Influencing factors include behaviors, lifestyle, diet, physical/mental health issues, and medications.
Insomnia Manifestations and Assessment
- Symptoms include difficulty falling/staying asleep, waking too early, and overall unrefreshing sleep.
- Utilizes self-reporting methods, sleep diaries, and comprehensive medical histories for diagnosis.
Insomnia Management
- Address short-term insomnia and treat chronic cases through education, behavioral strategies, and cognitive-behavioral therapy (CBT-I).
- Drug therapies include benzodiazepine-receptor agonists and orexin-receptor antagonists, but they entail risks like dependence and rebound insomnia.
- Emphasizes safe sleep hygiene practices and environmental adjustments for better sleep quality.
Sleep-Disordered Breathing (SDB)
- Characterized by abnormal respiratory patterns during sleep, leading to snoring, apnea, and daytime sleepiness.
- Obstructive sleep apnea (OSA) is the most common form, affecting about 25% of adults.
Obstructive Sleep Apnea (OSA)
- Defined by intermittent airway obstruction during sleep, primarily occurring in the REM phase.
- Symptoms include frequent arousals, excessive daytime sleepiness, snoring, and morning headaches.
- Associated risks include hypertension, type 2 diabetes, and cardiovascular complications.
Diagnostic Studies for OSA
- Use of sleep history questionnaires (Berlin, STOP-BANG) and sleepiness scales (Epworth) to identify OSA.
- Polysomnography (PSG) used to assess sleep stages, airflow, and other physiological parameters during sleep.
Management of OSA
