Common Sleep Disorders

SMH facility The Sibley Sleep Center

Common symptoms of sleep disorders include loud and/or irregular snoring, excessive daytime sleepiness, depressed or anxious mood, interruptions in breathing during sleep and/or complaints of inability to fall asleep or maintain sleep.

The most common sleep disorders are:

  • Sleep Apnea Syndrome. People with sleep apnea may stop breathing several times during sleep. These apneic episodes last from 10 to 120 seconds and may occur as often as several hundred times a night. Symptoms include heavy snoring, fitful and restless sleep, excessive daytime sleepiness, morning headaches, obesity, high blood pressure, and depression.
  • Periodic Limb Movements of Sleep. People with this disorder may not receive proper rest at night and consequently feel as though they have insomnia or excessive daytime sleepiness.
  • Narcolepsy. People who are too sleepy during the day, or have almost irresistible urges to take daytime naps, may have narcolepsy. These individuals also may experience muscular weakness when they are angry, surprised or amused.
  • Conditional Insomnia. There are many causes of insomnia. The most common factors causing conditional insomnia are:
    • Depression
    • Stress
    • Noise/environmental conditions
    • Breathing problems
    • Illness
    • The use of drugs or medications, including alcohol
