Types


Types, Sleep-Disorders

Circadian rhythm sleep disorders (CRSDs) are characterized by a misalignment between the body’s natural sleep-wake cycle and the desired sleep-wake cycle. This misalignment can make it difficult to fall asleep, stay asleep, or wake up at the desired time. There are several types of CRSDs, including:

  • Delayed sleep phase disorder (DSPD): People with DSPD have a sleep-wake cycle that is delayed by several hours. They typically fall asleep late at night and wake up late in the morning.
  • Advanced sleep phase disorder (ASPD): People with ASPD have a sleep-wake cycle that is advanced by several hours. They typically fall asleep early in the evening and wake up early in the morning.
  • Non-24-hour sleep-wake disorder: People with non-24-hour sleep-wake disorder have a sleep-wake cycle that is not synchronized with the 24-hour day. They may sleep for long periods of time during the day and night, and their sleep-wake cycle may vary from day to day.
  • Shift work sleep disorder: People with shift work sleep disorder have difficulty sleeping during the night and staying awake during the day because their work schedule is out of sync with their natural sleep-wake cycle.
  • Jet lag: Jet lag is a temporary sleep disorder that occurs when a person travels across multiple time zones. Jet lag can cause insomnia, excessive daytime sleepiness, and fatigue.

All of these types of CRSDs can have a significant impact on a person’s quality of life. People with CRSDs may have difficulty functioning during the day, and they may be at increased risk for accidents and injuries. Treatment for CRSDs typically involves a combination of light therapy, melatonin, sleep restriction therapy, and cognitive behavioral therapy.
