Exempel på hur man kan använda NREM i en mening

• Delta waves, like other brain waves, can be recorded with electroencephalography (EEG) and are usually associated with the deep stage 3 of NREM sleep, also known as slow-wave sleep (SWS), and aid in characterizing the depth of sleep.
• According to studies, the mental activity that takes place during NREM sleep is believed to be thought-like, whereas REM sleep includes hallucinatory and bizarre content.
• These include insomnia disorders, hypersomnolence disorders, narcolepsy, obstructive sleep apnea hypopnea, central sleep apnea, sleep-related hypoventilation, circadian rhythm sleep-wake disorders, non–rapid eye movement (NREM) sleep arousal disorders, nightmare disorders, rapid eye movement (REM) sleep behavior disorders, restless legs syndrome (RLS), and substance-medication-induced sleep disorders.
• It can occur many times during a sleep cycle and during both NREM and REM sleep stages, though, as with sleepwalking and night terrors, it most commonly occurs during delta-wave NREM sleep or temporary arousals therefrom.
• Slow-wave sleep (SWS), often referred to as deep sleep, is the third stage of non-rapid eye movement sleep (NREM), where electroencephalography activity is characterised by slow delta waves.
• Parasomnias are dissociated sleep states which are partial arousals during the transitions between wakefulness, NREM sleep, and REM sleep, and their combinations.
• Additionally, there is a close association with Alpha waves that contain a mixture of K complexes and arousals, regardless of the NREM stage in which the RMD occurred.
• Hypoxemia due to hypoventilation is noted in REM sleep but this is less well studied than NREM sleep.
• In a study on cognitive flexibility across the sleep-wake cycle, researchers discovered that when woken from REM sleep, participants had a 32% advantage on an anagram task (when compared with the number of correct responses after NREM awakenings).
• Reports from REM awakenings tend to be longer, more multimodal perceptually, have intensified emotionality, and are less reminiscent of waking life than NREM awakenings.
• For example, the anticonvulsant Phenytoin (PHT) can be seen to disrupt sleep by increasing the duration of NREM stage 1 and decreasing the duration of SWS; whereas the drug Gabapentin is seen to revive sleep by increasing the duration of SWS.
• NREM Stage 2 (N2 – 45–55% of total sleep in adults): In this stage, theta activity is observed and sleepers become gradually harder to awaken; the alpha waves of the previous stage are interrupted by abrupt activity called sleep spindles (or thalamocortical spindles) and K-complexes.
• Confusional arousals are associated with behavioural awakening with persistent slow-wave electroencephalographic activity (see slow-wave sleep) during Non-rapid eye movement sleep (NREM).
