🔴 Resumen TRASTORNOS DEL SUEÑO VIGILIA (INSOMNIO, HIPERSOMNIA Y NARCOLEPSIA) DSM 5-TR

Understanding Sleep Disorders: Insomnia

Overview of Sleep Disorders

• The session introduces sleep-wake disorders, focusing on insomnia as a primary concern.

• Sleep disorders lead to dissatisfaction with sleep quality, timing, and quantity, resulting in daytime distress and cognitive impairment.

Diagnostic Criteria for Insomnia

• Key diagnostic criteria include:

• Quality and Quantity: Dissatisfaction due to difficulty initiating or maintaining sleep.

• Significant Distress: Impairment in functional areas such as work or education.

• Frequency: Symptoms occurring at least three times per week over a minimum of three months.

• Favorable Conditions: Issues arise despite having an appropriate sleeping environment.

• Exclusion of Other Disorders: Symptoms not better explained by other sleep disorders or substance effects.

Characteristics and Prevalence

• Insomnia can manifest as initial difficulties falling asleep or maintaining it, often leading to non-restorative sleep experiences.

• According to DSM-5 TR data, insomnia is the most prevalent sleep disorder globally, affecting about one-third of adults.

Demographics and Associated Factors

• Approximately 10-15% report daytime impairments; 4-22% meet full criteria for insomnia.

• Higher prevalence noted among individuals with mental health issues (40-50%) and more common in women (1.7 women for every man).

Causes of Insomnia

Psychological Factors

• Stressful life events can trigger situational insomnia; symptoms may persist even after stressors are resolved.

Inadequate Sleep Habits

• Irregular sleeping patterns, excessive napping, and stimulant consumption before bed negatively impact sleep quality.

Physical Health Issues

• Chronic pain, respiratory problems, restless legs syndrome, or hormonal disorders can contribute to insomnia risk.

Treatment Approaches

Multidisciplinary Strategies

• Treatment often involves medication management alongside psychological interventions targeting underlying causes.

Cognitive Behavioral Therapy for Insomnia (CBT-I)

Sleep Disorders and Their Treatments

Sleep Hygiene and Environment

• Activities unrelated to sleep can create a negative association with the bed, leading individuals to perceive it as a place for physiological activation rather than rest.

• Sleep hygiene treatments provide guidelines to foster healthy sleep habits, including maintaining a regular sleep schedule, avoiding stimuli before bedtime, and creating a calm sleeping environment.

• Relaxation techniques such as deep breathing, progressive muscle relaxation, or meditation are taught to reduce anxiety and physiological activation before sleep.

Understanding Hypersomnia

• Hypersomnia is characterized by excessive daytime sleepiness despite adequate nighttime sleep; affected individuals often struggle to wake up even after long hours of rest.

• Diagnostic criteria include excessive daytime drowsiness after at least seven hours of sleep, recurrent periods of falling asleep during the day, prolonged non-restorative nighttime sleep exceeding nine hours, and difficulty staying awake post-wakefulness.

• Symptoms must occur at least three times weekly for three months and cause significant distress or impairment in cognitive, social, or occupational functioning.

Causes and Characteristics of Hypersomnia

• Hypersomnia cannot be better explained by other sleep disorders (e.g., narcolepsy or breathing-related disorders), nor attributed to substance effects.

• Associated characteristics include ease of falling asleep during the day, decreased motor skills upon waking, inappropriate behaviors, memory deficits, disorientation in time/space, and dizziness lasting minutes to hours.

Prevalence and Contributing Factors

• The prevalence of hypersomnia ranges from 5% to 10% among patients seeking medical help for sleep issues; it affects about 1% of the global population equally across genders.

• Multiple factors contribute to hypersomnia: other sleep disorders (like apnea), psychological issues (chronic stress or depression), certain medications (antidepressants), substance abuse (alcohol/drugs), and physical health problems (fibromyalgia).

Treatment Approaches for Hypersomnia

• Interdisciplinary treatment may involve cognitive-behavioral therapy addressing psychological factors related to hypersomnia while improving overall sleep hygiene practices.

• Healthy sleeping habits include establishing regular routines, creating conducive environments for rest, avoiding excessive napping during the day, and limiting stimulants like caffeine/alcohol before bed.

• Stress reduction techniques such as meditation or deep breathing exercises can enhance overall sleep quality while decreasing daytime drowsiness.

Pharmacological Interventions

• Stimulant medications like modafinil or methylphenidate may be prescribed to alleviate daytime drowsiness by enhancing alertness throughout the day.

• Light therapy has shown effectiveness in regulating circadian rhythms through exposure to bright light in the morning which promotes appropriate wakefulness during daylight hours.

Narcolepsy Overview

Narcolepsy: Understanding Symptoms and Diagnosis

Overview of Narcolepsy Symptoms

• Narcolepsy is characterized by uncontrollable episodes of sudden sleep and brief naps during normal activities, often accompanied by cataplexy, sleep paralysis, and hypnagogic hallucinations.

Diagnostic Criteria for Narcolepsy

• The first diagnostic criterion includes recurrent periods of an irresistible need to sleep or nap during the day at least three times a week over the last three months.

• The second criterion involves at least one of the following features: cataplexy (a sudden loss of muscle tone triggered by strong emotions), which can range from mild weakness to complete loss of control.

Additional Diagnostic Features

• A deficiency in hypocretin in cerebrospinal fluid is another key feature; hypocretin helps maintain wakefulness. Levels must be below 110 pg/ml without any brain injury or infection.

• The third characteristic is observed through polysomnography showing REM sleep duration equal to or less than 15 minutes, or two or more REM periods occurring at the start of multiple sleep latency tests.

Severity Levels of Narcolepsy

• Narcolepsy severity ranges from mild (cataplexy occurs less than once a week and minimal nighttime disturbance) to severe (frequent cataplexy resistant to medication with constant daytime sleepiness).

Prevalence and Causes

• The prevalence of narcolepsy is between 0.02% and 0.05% in adults, with no gender differences noted. Its causes are not fully understood but involve genetic, neurochemical, and environmental factors.

Treatment Options for Narcolepsy

• Treatment focuses on managing symptoms rather than curing narcolepsy. Stimulants like modafinil help reduce daytime drowsiness while antidepressants may assist with cataplexy symptoms.

• Sodium oxybate can improve nighttime sleep quality and reduce awakenings. Behavioral therapy aids in developing healthy sleep habits.

Lifestyle Recommendations

• Maintaining a healthy lifestyle with regular sleep routines, avoiding stimulants before bed, and practicing relaxation techniques are crucial for improving overall well-being.
