Narcoleptics typically have higher REM sleep density than non-narcoleptics, but also experience more REM sleep without atonia. [16] Many narcoleptics have sufficient REM sleep, but do not feel refreshed or alert throughout the day. [17] This can feel like living their entire lives in a constant state of sleep deprivation.

It is sometimes called the ultradian sleep cycle, sleep–dream cycle, or REM-NREM cycle, to distinguish it from the circadian alternation between sleep and wakefulness. In humans, this cycle takes 70 to 110 minutes (90 ± 20 minutes). [1] Within the sleep of adults and infants there are cyclic fluctuations between quiet and active sleep.
The Sleep Timing Questionnaire is a 10-minute self-administration test that can be used in place of a 2-week sleep diary. The questionnaire can be a valid determinate of sleep parameters such as bed time, wake time, sleep latency, and wake after sleep onset.
Parasomnias like sleepwalking and talking typically occur during the first part of an individual's sleep cycle, the first slow wave of sleep [63] During the first slow wave of sleep period of the sleep cycle the mind and body slow down causing one to feel drowsy and relaxed.

It is used to measure the time it takes from the start of a daytime nap period to the first signs of sleep, called sleep latency. Subjects undergo a series of five 20-minute sleeping opportunities with an absence of alerting factors at 2-hour intervals on one day.
The whole period normally proceeds in the order: N1 → N2 → N3 → N2 → REM. REM sleep occurs as a person returns to stage 2 or 1 from a deep sleep. [20] There is a greater amount of deep sleep (stage N3) earlier in the night, while the proportion of REM sleep increases in the two cycles just before natural awakening. [17]
Solriamfetol is used to promote wakefulness in the treatment of excessive daytime sleepiness associated with narcolepsy or obstructive sleep apnea in adults. [1] It appears to be more effective in improving excessive daytime sleepiness associated with obstructive sleep apnea than certain other wakefulness-promoting agents including modafinil, armodafinil, and pitolisant.
