PSYCHOLOGY OF EMOTIONS

Detailed explanation-1: -Narcolepsy is a disorder of rapid onset rapid eye movement (REM) sleep characterized by excessive daytime sleepiness (EDS), frequent uncontrollable sleep attacks as well as sleep fragmentation and can be associated with cataplexy, sleep paralysis, and hypnagogic hallucinations.

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-3: -NARCOLEPSY IS CHARACTERIZED BY THE PRESENCE OF EXCESSIVE DAYTIME SLEEPINESS AND CLINICAL MANIFESTATIONS OF DISSOCIATED RAPID EYE MOVEMENT (REM) sleep including cataplexy, hypnagogic and hypnopompic hallucinations, and sleep paralysis.

Detailed explanation-4: -Overview. Narcolepsy is a sleep disorder that makes people very drowsy during the day. People with narcolepsy find it hard to stay awake for long periods of time. They fall asleep suddenly. This can cause serious problems in their daily routine.

Detailed explanation-5: -Many cases of narcolepsy are thought to be caused by a lack of a brain chemical called hypocretin (also known as orexin), which regulates sleep. The deficiency is thought to be the result of the immune system mistakenly attacking parts of the brain that produce hypocretin.
