AP PSYCHOLOGY

Detailed explanation-1: -In narcolepsy, you may suddenly enter REM sleep without going through NREM sleep. This can happen both at night and during the day. Cataplexy, sleep paralysis and hallucinations are similar to changes that occur in REM sleep. But in narcolepsy they happen while you’re awake or drowsy.

Detailed explanation-2: -People with narcolepsy frequently enter REM sleep rapidly, within 15 minutes of falling asleep. Also, the muscle weakness or dream activity of REM sleep can occur during wakefulness or be absent during sleep. This helps explain some symptoms of narcolepsy.

Detailed explanation-4: -Since the discovery of sleep onset REM periods (SOREMPs) in narcoleptic patients, narcolepsy has often been regarded as a disorder of REM sleep generation: REM sleep intrudes in active wake or at sleep onset, resulting in cataplexy, sleep paralysis, or hypnagogic hallucinations.

Detailed explanation-5: -Types of narcolepsy Type 1 narcolepsy used to be known as “narcolepsy with cataplexy.” Type 2 used to be called “narcolepsy withoutcataplexy.” In very rare cases, a person may develop another type of narcolepsy known as secondary narcolepsy.
