PSYCHOLOGY OF EMOTIONS

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: -Narcolepsy is not a seizure. It is a lack of a protein in your brain called hypocretin, believed to be destroyed by your immune system. Hypocretin works in your hypothalamus by regulating chemicals that cause you to fall asleep and remain awake.

Detailed explanation-3: -What causes narcolepsy. Narcolepsy is often caused by a lack of the brain chemical hypocretin (also known as orexin), which regulates wakefulness. The lack of hypocretin is thought to be caused by the immune system mistakenly attacking the cells that produce it or the receptors that allow it to work.

Detailed explanation-4: -As discussed in the REM behavior disorder section, muscle atonia, or sleep paralysis most commonly occurs when a person is either falling asleep awakening.
