Insomnia

 

What is insomnia?

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or both, despite having adequate opportunity to sleep. It can lead to daytime fatigue, mood disturbances, and impaired performance. 

Key Terms:

• Acute insomnia: Short-term insomnia lasting from a few days to a few weeks.
• Chronic insomnia: Insomnia that occurs at least three nights a week for three months or longer.
• Sleep efficiency: The ratio of time spent asleep to time spent in bed, often used to measure insomnia severity.

 

What are the symptoms of insomnia?

Symptoms include: - Trouble falling asleep at night - Waking up during the night - Waking up too early - Feeling unrefreshed upon waking - Daytime fatigue and sleepiness - Difficulty concentrating or remembering 

How is insomnia treated?

Treatment options include: - Improving sleep hygiene (e.g., maintaining a regular sleep schedule, creating a comfortable sleep environment) - Cognitive Behavioral Therapy for Insomnia (CBT-I) - Relaxation techniques - In some cases, short-term use of sleep medications 

Key Concepts:

• Sleep hygiene: Practices and habits that promote good sleep quality and daytime alertness.
• CBT-I: A structured program that helps identify and replace thoughts and behaviors that cause or worsen sleep problems with habits that promote sound sleep.
• Sleep restriction therapy: A component of CBT-I that involves limiting time in bed to increase sleep efficiency.

 

Sleep Apnea

 

What is sleep apnea?

Sleep apnea is a condition where breathing repeatedly stops and starts during sleep. The most common type is obstructive sleep apnea (OSA). Types of Sleep Apnea:

1. Obstructive Sleep Apnea (OSA): Caused by physical blockage of the airway.
2. Central Sleep Apnea (CSA): Caused by the brain failing to signal the muscles to breathe.
3. Mixed Sleep Apnea: A combination of OSA and CSA.

What are the symptoms of sleep apnea?

Symptoms include: - Loud snoring - Gasping for air during sleep - Excessive daytime sleepiness - Morning headaches - Difficulty concentrating 

Key Terms:

• Apnea: A pause in breathing lasting at least 10 seconds.
• Hypopnea: A partial blockage of airflow leading to a drop in blood oxygen levels.
• AHI (Apnea-Hypopnea Index): The number of apneas and hypopneas per hour of sleep, used to classify sleep apnea severity.

 

How is sleep apnea treated?

Treatment options include: - Continuous Positive Airway Pressure (CPAP) therapy - Lifestyle changes (e.g., weight loss, avoiding alcohol before bed) - Oral appliances - In some cases, surgery 

Key Concepts:

• CPAP: A machine that delivers a constant stream of air pressure to keep the airway open during sleep.
• Mandibular advancement device: An oral appliance that moves the lower jaw forward to help keep the airway open.
• Uvulopalatopharyngoplasty (UPPP): A surgical procedure to remove excess tissue in the throat to widen the airway.

 

Narcolepsy

 

What is narcolepsy?

Narcolepsy is a chronic neurological disorder that affects the brain's ability to control sleep-wake cycles, causing excessive daytime sleepiness and sudden sleep attacks. Types of Narcolepsy:

1. Narcolepsy Type 1: Characterized by cataplexy and low levels of hypocretin in the brain.
2. Narcolepsy Type 2: Without cataplexy, and normal hypocretin levels.

What are the symptoms of narcolepsy?

Symptoms include: - Excessive daytime sleepiness - Sudden loss of muscle tone (cataplexy) - Sleep paralysis - Hallucinations when falling asleep or waking up 

Key Terms:

• Cataplexy: Sudden, brief loss of muscle tone triggered by strong emotions.
• Hypocretin (Orexin): A neurotransmitter that regulates wakefulness and REM sleep.
• Sleep paralysis: Temporary inability to move or speak while falling asleep or upon waking.

 

How is narcolepsy treated?

Treatment options include: - Medications to promote wakefulness (e.g., modafinil, methylphenidate) - Medications to manage cataplexy (e.g., sodium oxybate) - Lifestyle adjustments (e.g., scheduled naps, regular sleep schedule) 

Key Concepts:

• Multiple Sleep Latency Test (MSLT): A diagnostic test measuring how quickly a person falls asleep in a quiet environment during the day.
• REM sleep: Rapid Eye Movement sleep, a stage of sleep associated with dreaming and paralysis of major muscle groups.

 

Restless Legs Syndrome (RLS)

 

What is restless legs syndrome?

Restless legs syndrome is a neurological disorder characterized by an irresistible urge to move the legs, often accompanied by uncomfortable sensations. 

What are the symptoms of restless legs syndrome?

Symptoms include: - An overwhelming urge to move the legs, especially at night - Uncomfortable sensations in the legs (e.g., crawling, creeping, pulling) - Symptoms that worsen with rest and improve with movement - Sleep disturbances 

Key Terms:

• Periodic Limb Movement Disorder (PLMD): A condition often associated with RLS, characterized by repetitive limb movements during sleep.
• Circadian rhythm: The body's internal 24-hour clock that regulates sleep-wake cycles.

 

How is restless legs syndrome treated?

Treatment options include: - Lifestyle changes (e.g., regular exercise, avoiding caffeine and alcohol) - Iron supplements (if deficient) - Medications (e.g., dopamine agonists, anti-seizure drugs) - Addressing underlying conditions (if applicable) 

Key Concepts:

• Dopamine: A neurotransmitter involved in movement control and believed to play a role in RLS.
• Augmentation: A potential side effect of dopaminergic medications where RLS symptoms worsen over time or spread to other parts of the body.

 

General Sleep Disorder Information

 

How are sleep disorders diagnosed?

Sleep disorders are often diagnosed through: - Sleep studies (polysomnography) - Multiple Sleep Latency Test (MSLT) - Actigraphy - Medical history and physical examination 

Key Terms:

• Polysomnography: A comprehensive overnight sleep study that records brain waves, oxygen levels, heart rate, breathing, and eye and leg movements.
• Actigraphy: A method of monitoring human rest/activity cycles using a small wearable device.

 

What are some common risk factors for sleep disorders?

Risk factors can include: - Age (some disorders are more common in older adults) - Gender (certain disorders affect men or women more frequently) - Obesity - Family history - Certain medical conditions - Medications - Lifestyle factors (e.g., shift work, high stress) 

Key Concepts:

• Comorbidity: The presence of one or more additional conditions co-occurring with a primary condition.
• Circadian rhythm disorders: A group of sleep disorders that occur when the sleep-wake cycle is out of alignment with the day-night cycle.

 

When should someone seek help for a sleep disorder?

It's advisable to consult a healthcare provider if: - Sleep problems persist for several weeks - Daytime functioning is significantly impaired - Sleep issues interfere with daily activities or quality of life - There are concerns about breathing during sleep 

Key Terms:

• Sleep hygiene: Practices and habits that are conducive to sleeping well on a regular basis.
• Sleep medicine: A medical specialty devoted to the diagnosis and therapy of sleep disturbances and disorders.
