-
Sleep Apnea
- Definition: A potentially serious sleep disorder characterized by repeated interruptions in breathing during sleep.
- Types of sleep apnea:
- Obstructive Sleep Apnea (OSA): Caused by throat muscles relaxing and blocking the airway.
- Central Sleep Apnea: Occurs when the brain fails to send signals to the muscles that control breathing.
- Complex Sleep Apnea Syndrome: A combination of obstructive and central sleep apnea.
- Types of sleep apnea:
- Symptoms:
- Loud snoring, choking or gasping during sleep, excessive daytime sleepiness.
- Definition: A potentially serious sleep disorder characterized by repeated interruptions in breathing during sleep.
-
Narcolepsy
- Definition: A neurological disorder affecting the control of sleep and wakefulness.
- Types of narcolepsy:
- Narcolepsy Type 1: Characterized by excessive daytime sleepiness combined with cataplexy (sudden muscle weakness).
- Narcolepsy Type 2: Excessive daytime sleepiness without cataplexy.
- Types of narcolepsy:
- Symptoms:
- Sudden sleep attacks, sleep paralysis, vivid hallucinations.
- Definition: A neurological disorder affecting the control of sleep and wakefulness.
-
Parasomnias
- Definition: Abnormal behaviors during sleep, including movements, emotions, and experiences.

- Definition: Disorders that affect the timing of sleep and wakefulness, often resulting from a misalignment between an individual’s internal clock and societal demands.
- Types:
- Delayed Sleep Phase Disorder: A significant delay in the sleep-wake cycle, often leading to late bedtimes and difficulty waking up.
- Advanced Sleep Phase Disorder: An earlier-than-normal sleep-wake cycle, leading to early bedtimes and early morning awakenings.
- Shift Work Disorder: Disruptions in sleep patterns due to night shifts or irregular work hours.
- Types:

- Definition: Disorders that affect the timing of sleep and wakefulness, often resulting from a misalignment between an individual’s internal clock and societal demands.
Conclusion
Sleep-wake disorders encompass a variety of conditions that can severely impact behavior, mood, and overall health. Recognizing the different types—such as insomnia, sleep apnea, narcolepsy, parasomnias, and circadian rhythm disorders—allows for better diagnosis and treatment options. Addressing these issues is essential for improving the quality of life for those affected.
