Overview of Sleep Disorders

What Are Sleep Disorders?

Sleep disorders encompass a range of conditions that interfere with your ability to sleep well. These conditions may impact:

• Quality: How restful your sleep is.

• Duration: How long you sleep.

• Timing: When you fall asleep and wake up.

Sleep disorders are more than occasional sleep problems. They are chronic conditions that can lead to serious health issues if left untreated. Common symptoms include trouble falling asleep, staying asleep, or feeling excessively tired during the day despite adequate rest.

Key Categories of Sleep Disorders

The International Classification of Sleep Disorders (ICSD-3R) categorizes sleep disorders into several groups:

1. Insomnia: Difficulty falling or staying asleep.

2. Sleep-Related Breathing Disorders: Conditions affecting breathing during sleep, such as sleep apnea.

3. Central Disorders of Hypersomnolence: Excessive sleepiness, such as narcolepsy.

4. Circadian Rhythm Sleep-Wake Disorders: Misalignment of the internal body clock with external cues.

5. Parasomnias: Abnormal behaviors or experiences during sleep, such as sleepwalking.

6. Sleep-Related Movement Disorders: Conditions like restless legs syndrome.

How Common Are Sleep Disorders?

Over 50 million Americans and more than 100 million individuals worldwide suffer from sleep disorders. Despite their prevalence, many cases remain undiagnosed or untreated.
