Narcolepsy and Sleep Stages

Very Hard Unit 10: States Of Consciousness Sleep And Dreams

In the study of sleep and dreams, scientists have identified various sleep disorders that can disrupt normal sleep patterns. One such disorder, narcolepsy, is marked by excessive daytime sleepiness and sudden sleep attacks. During an episode of narcolepsy, individuals may experience a phenomenon known as cataplexy, which involves a sudden loss of muscle tone. This leads researchers to investigate the specific neurobiological mechanisms underlying narcolepsy and its impact on sleep architecture, particularly how it affects the transitions between sleep stages. Which of the following statements most accurately describes an aspect of narcolepsy in relation to sleep stages?

Narcolepsy is primarily characterized by an advanced onset of slow-wave sleep early in the night.

Individuals with narcolepsy typically experience prolonged periods of rapid eye movement (REM) sleep without interruption.

Narcolepsy often leads to the intrusion of REM sleep into waking periods during the day.

Those suffering from narcolepsy usually have a disrupted circadian rhythm that prevents deep sleep.

Narcolepsy is solely related to a lack of nighttime sleep, resulting in excessive sleepiness regardless of daytime duration.
